A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid.

Regulation of human airway mucins by acrolein and inflammatory mediators. (1/163)

Bronchitis, asthma, and cystic fibrosis, marked by inflammation and mucus hypersecretion, can be caused or exacerbated by airway pathogens or irritants including acrolein, an aldehyde present in tobacco smoke. To determine whether acrolein and inflammatory mediators alter mucin gene expression, steady-state mRNA levels of two airway mucins, MUC5AC and MUC5B, were measured (by RT-PCR) in human lung carcinoma cells (NCI-H292). MUC5AC mRNA levels increased after >/=0.01 nM acrolein, 10 microM prostaglandin E2 or 15-hydroxyeicosatetraenoic acid, 1.0 nM tumor necrosis factor-alpha (TNF-alpha), or 10 nM phorbol 12-myristate 13-acetate (a protein kinase C activator). In contrast, MUC5B mRNA levels, although easily detected, were unaffected by these agonists, suggesting that irritants and associated inflammatory mediators increase mucin biosynthesis by inducing MUC5AC message levels, whereas MUC5B is constitutively expressed. When transcription was inhibited, TNF-alpha exposure increased MUC5AC message half-life compared with control level, suggesting that transcript stabilization is a major mechanism controlling increased MUC5AC message levels. Together, these findings imply that irritants like acrolein can directly and indirectly (via inflammatory mediators) increase airway mucin transcripts in epithelial cells.  (+info)

Sclerosing Mucoepidermoid carcinoma with eosinophilia of the thyroid glands: a case report with clinical manifestation of recurrent neck mass. (2/163)

Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) is a recently recognized malignant neoplasm of the thyroid gland. About 14 cases of SMECE have been reported and this is the first reported case in Korea. A 57-year-old woman presented with right neck mass for 20 years. Total thyroidectomy was performed under the impression of thyroid carcinoma. The resected thyroid gland showed a poorly circumscribed hard mass. Histologically, the tumor consisted of solid nests of large atypical cells with dense fibrous stroma. The tumor cells showed squamoid appearance with abundant eosinophilic cytoplasm. There were also rare mucin-containing cells within the nests. Within the hyalinized stroma, numerous eosinophils were found. The surrounding thyroid parenchyma displayed Hashimoto's thyroiditis. There was metastasis in a regional lymph node. Two years after initial surgery, she underwent a modified radical neck dissection due to recurrent neck mass. After the radiation therapy for eight weeks, laryngectomy and esophagectomy were performed due to a recurrent carcinoma in the esophageal wall. We report an additional case of SMECE, with metastasis to regional lymph nodes and esophagus. The tumor appears to be more aggressive than previously reported and a correct diagnosis can be rendered by just examining the metastatic lesions.  (+info)

Characterization of CFTR expression in a human pulmonary mucoepidermoid carcinoma cell line, NCI-H292 cells. (3/163)

The NCI-H292 cell, a human pulmonary mucoepidermoid carcinoma cell line, is commonly used for studying bacterial and viral infections of airway epithelial cells. Dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) is the main cause of fetal lung infection in cystic fibrosis patients. In this study, we examined CFTR expression in NCI-H292 cells to determine whether NCI-H292 cells possess sufficient, normally functioning CFTR. The results of RT-PCR and Northern blotting analysis indicated that the CFTR gene expression level was much lower in NCI-H292 cells than in T84 cells. However, Western blotting analysis showed that protein expression in NCI-H292 cells was comparable to that in T84 cells. Furthermore, whole-cell and cell-attached patch clamp electrophysiological techniques indicated that the Cl- current induced by intracellular cAMP elevation in NCI-H292 cells was comparable to that in T84 cells. These findings suggest that NCI-H292 cells with a low level of CFTR gene expression possess enough functional CFTR to show a physiological response.  (+info)

Salivary gland tumors in Jordan: a retrospective study of 221 patients. (4/163)

AIM: To evaluate the types and clinical outcome of salivary gland tumors in Jordan. METHODS: Hospital records of 221 patients (85 women and 136 men) with salivary gland tumors, diagnosed from January 1988 to December 1997 were reviewed. The patients were analyzed according to sex, age, histopathological type and site of the tumor. Survival curves for patients with malignant tumors were constructed using Kaplan-Meier's method. RESULTS: Of the total 221 salivary gland tumors, 155 (70.2%) were parotid tumors, 42 (19%) minor salivary gland tumors, 23 (10.4%) submandibular gland tumors, and a single (0.4%) sublingual gland tumor. Most of the tumors (151, or 68.4%) were classified as benign and 70 (31.6%) were malignant. Men to women ratio was 1.6:1, and the age of the patients ranged from 2 to 81 years. The overall 5 and 10 year-survival rates for the 70 malignant tumors were 67% and 53%, respectively, for all tumor stages. Mucoepidermoid carcinoma had the best, and squamous cell carcinoma the worst 10-year survival rate. Patients treated with surgery and subsequent radiation therapy had better survival rates than those treated with surgery or radiation therapy alone. CONCLUSION: The principal site for salivary gland tumors in Jordan population was the parotid, and the pleo- morphic adenoma the most common pathological finding. Tumor characteristics and survival data for the Jordanian population are comparable to those from western countries.  (+info)

Detection of circulating anti-p53 antibodies in esophageal cancer patients. (5/163)

It has been reported that circulating anti-p53 antibodies (p53-Ab) in the serum are detected in some cancers. To investigate the usefulness of detecting p53-Ab, we measured the circulating p53-Ab in comparison with squamous cell carcinoma antigen (SCC-Ag) in patients with esophageal carcinoma. Serum specimens from 46 esophageal cancer patients (42 squamous cell carcinomas, 3 mucoepidermoid carcinomas and 1 basaloid squamous carcinoma) and 13 healthy subjects were studied. Serum p53-Ab was measured by an enzyme-linked immunosorbent assay. Surgically resected specimens from 43 patients were immunohistochemically stained for p53. Serum SCC-Ag was measured by a radioimmunoassay. The results were analyzed with the clinical data and outcome. Serum p53-Ab was detected in 13 (28%) of the 46 patients, but not in any of the healthy subjects. The positive rate was 0% (0/6) in stage I, 60% (3/5) in stage IIA, 30% (3/10) in stage IIB, 29% (7/24) in stage III and 0% (0/1) in stage IV. There was no difference in the outcome between the p53-Ab-positive and p53-Ab-negative patients. Immunohistochemically, 30 (70%) of the 43 specimens stained positively for p53. Serum p53-Ab was detected in 43% (13/30) of the patients with tumors which stained positively for p53. There was a close correlation between positivity for p53 immunostaining and positivity for p53-Ab (p<0.01). An elevated level of SCC-Ag was found in only 13%of the patients, and most patients positive for SCC-Ag already had advanced disease with lymph node metastasis and invasion to the adventitia. In conclusion, serum p53-Ab was detected in Japanese esophageal cancer patients at a frequency similar to that reported in Western countries. Serum p53-Ab may be a potentially useful molecular marker for detection and screening of esophageal cancer. Further studies of a large population may be required to elucidate the true diagnostic usefulness of measuring the serum p53-Ab.  (+info)

Failure patterns and factors affecting prognosis of salivary gland carcinoma: retrospective study. (6/163)

OBJECTIVES: To investigate the failure patterns and the prognostic factors following postoperative radiotherapy for salivary gland carcinoma. DESIGN: Retrospective study. SETTING: University teaching hospital, Hong Kong. PATIENTS: Fifty patients who had non-disseminated salivary gland carcinoma and who received primary treatment from 1984 through 1993. MAIN OUTCOME MEASURES: Demographic data, cancer T- and N-stages, histological type, site of origin, completeness of surgery, whether postoperative radiotherapy was given, and the clinical outcome. RESULTS: Two (4%) patients had been treated with radiotherapy alone, six (12%) had undergone radical resection alone, and 42 (84%) had been radically treated by using both modalities. The 5-year overall survival and relapse-free survival rates were 78.4% and 63.1%, respectively. The free from local failure and free from distant metastasis rates at 5 years were 77.2% and 72.8%, respectively. The N-stage was a significant prognostic factor. The site of the primary tumour, T-stage, completeness of surgery, and use of postoperative radiotherapy were not significant independent prognosticators; however, among the T-stage tumours, the b-substage carcinomas had significantly fewer local failures (P=0.040) and better survival rates (P=0.038) than the a-substage carcinomas. There were seven (14%) locoregional failures without distant metastasis, seven (14%) cases of distant metastasis without locoregional failures, and four (8%) locoregional failures preceding distant metastasis; isolated regional relapse was rare (1/50; 2%). All regional failures (5/50; 10%) occurred ipsilateral to the primary lesion. There were no deaths due to lymphoepithelioma-like carcinoma or acinic cell carcinoma. CONCLUSIONS: The N-stage is the main prognostic factor of overall survival, relapse- and metastasis-free recovery, and success of treatment for salivary gland carcinoma. Optimal locoregional treatment can help reduce distant metastasis, and the maximal use of postoperative radiotherapy may contribute to improved locoregional control. Elective ipsilateral neck radiotherapy is indicated for lymphoepithelioma-like carcinoma.  (+info)

Proliferating cell nuclear antigen expression in mucoepidermoid carcinoma of salivary glands. (7/163)

CONTEXT: Among the cytological and morphological properties of mucoepidermoid carcinoma, one of the most important criteria for measuring its biological behavior and aggressiveness is cell proliferation. In this way, immunohistochemical markers of cell proliferation have been found to be useful in tumor classification and have formed part of the prognostic and therapeutic studies of these pathologies. OBJECTIVE: To analyze 11 cases of mucoepidermoid carcinoma (MEC) using the proliferation activity marker (PCNA) and to determine its relationship to the grade of malignancy of these tumors. DESIGN: Correlation study. SETTING: Head and Neck Surgery Service of Heliopolis Hospital, Sao Paulo, Brazil. SAMPLE: Slides of 11 cases of primary mucoepidermoid carcinomas of salivary glands were prepared according to routine techniques employed in the Oral Pathology Department of the Dentistry Faculty of Sao Paulo University, Brazil. They were fixed in a 10% formaldehyde solution and stained with hematoxylin and eosin. After this preparation the tumors were classified as low, intermediate and high grade of malignancy, according to the criteria established by Seifert & Sobin and Auclair, Goode & Ellis. The slides were sent for immunohistochemical processing to evaluate the positivity of proliferating cell nuclear antigen using the streptavidin biotin technique. MAIN MEASUREMENT: The correlation between proliferating cell nuclear antigen expression and the histological malignancy grade in mucoepidermoid carcinoma of salivary glands. RESULTS: there were 4 cases (36%) of low grade, 4 cases (36%) of intermediate grade and 3 cases (27%) of high grade of malignancy. After a comparative study between histological features and immunohistochemical analysis, significant differences were observed (P < 0.01) for low, intermediate and high grades: 16.04%, 26.98% and 56.98% of proliferating cell nuclear antigen expression in mucoepidermoid carcinoma, respectively. CONCLUSION: The proliferating cell nuclear antigen expression increases with the grade of malignancy in mucoepidermoid carcinoma of salivary glands.  (+info)

Primary mucoepidermoid carcinoma and sclerosing mucoepidermoid carcinoma with eosinophilia of the thyroid gland: a report of nine cases. (8/163)

Mucoepidermoid carcinoma is a rare primary thyroid tumor with indolent biologic potential. Two types of tumors have been described under this category: mucoepidermoid carcinoma (MEC) and sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE). The MEC shows both squamous and glandular differentiation in a background of a noninflamed gland, whereas SMECE is characterized by extensive sclerosis, squamous and glandular differentiation, a concomitant inflammatory infiltrate rich in eosinophils, and a background of lymphocytic thyroiditis. We present nine cases of these entities: five MEC and four SMECE. All tumors occurred in women (age 27 to 73 years). Five tumors showed extrathyroidal invasion and multiple lymph node metastases. One case of MEC showed a concomitant tall cell variant of papillary carcinoma with vascular invasion, and two cases showed intimately associated areas of usual papillary carcinoma. One of the latter cases also showed areas of transformation to anaplastic carcinoma. In all cases of SMECE and in only one case of MEC, the uninvolved thyroid tissue showed lymphocytic thyroiditis. Follow-up information was available in four of the nine cases (3 months to 7 years). Two patients with SMECE are alive with no evidence of disease. One patient with MEC and tall cell variant of papillary carcinoma died of disease after 3 months, and the patient with anaplastic carcinoma died after 5 months with lung metastasis. Both MEC and SMECE were positive for cytokeratin and negative for calcitonin. All cases of MEC were positive for thyroglobulin, whereas all cases of SMECE were negative. The immunohistochemical findings suggest that both MEC and SMECE have different histogenesis.  (+info)

Oncocytic differentiation in mucoepidermoid carcinoma (MEC) is uncommon. Only twelve well-documented cases of oncocytic MEC have been reported previously all of which occurred in the parotid gland. To the best of our knowledge this is the first case of oncocytic mucoepidermoid carcinoma involving the submandibular salivary gland. The recognition of this ...
Central mucoepidermoid carcinoma (MEC) is a rare neoplasm arising intraosseously in the jaws. To clarify the clinicopathologic profile and pathogenesis of central MEC, clinicopathologic findings and follow-up data of 39 cases were collected and analyzed. There were 16 male and 23 female patients (median age, 43 y). Sixteen cases affected the maxilla, and 23 occurred in the mandible. Radiographically, most cases (32 of 39) showed a unilocular or multilocular radiolucency with bone destruction, and 7 were found with scattered calcification. The margins of the lesions were ill defined or diffused in 14 cases and relatively well defined in 25 cases. Most cases (26 of 39) were classified as low-grade MECs, whereas 13 were moderate-to-high grade. Follow-up data were available for 35 patients with a median period of 36 months. All cases were found to be primary; local recurrence occurred in 8 cases, most (75.0%) of which were low-grade tumors. Four cases showed regional lymph node metastasis, and I ...
The mucoepidermoid carcinoma is a rare tumor arising in the bronchial submucosal glands that shows an intimate admixture of glandular elements and sheets of cells with little or no definite squamous differentiation. The low grade mucoepidermoid carcinoma is a characteristic and readily recognized tumor. The very rare high grade mucoepidermoid carcinoma must be distinguished with care from the much more common adenosquamous bronchogenic carcinoma. The present case was a 45-year-old female patient with a several-year history of right chest pain and a few-day-history of coughing, fever, dyspnea. Under the bronchoscopic impression of the bronchial adenoma, right middle and lower lobectomy was done. Grossly, the endobronchial mass, 1.2×1.2cm, was located at the mainsterm bronchus branching to middle and lower lobe. It was well circumscribed. It occluded most of the bronchus supplying the lower lobe. The cut surface was whitish gray, relatively smooth and firm. Microscopically, the tumor consisted ...
Mucoepidermoid carcinoma is the most common type of minor salivary gland malignancy in adults. Mucoepidermoid carcinoma can also be found in other organs, such as bronchi, lacrimal sac and thyroid. Mucicarmine staining is one stain used by pathologist for detection. Occurs in adults, with peak incidence from 20-40 years of age. A causal link with cytomegalovirus (CMV) has been strongly implicated in a 2011 research. Presents as painless, slow-growing mass that is firm or hard. Most appear clinically as mixed tumors. This tumor is not encapsulated and is characterized by squamous cells, mucus-secreting cells, and intermediate cells. Mucoepidermoid carcinomas of the salivary and bronchial glands are characterized by a recurrent t(11;19)(q21;p13) chromosomal translocation resulting in a MECT1-MAML2 fusion gene. The CREB-binding domain of the CREB coactivator MECT1 (also known as CRTC1, TORC1 or WAMTP1) is fused to the transactivation domain of the Notch coactivator MAML2 PMID 16444749. A possible ...
CRTC1-MAML2 fusion is often detected in low- or intermediate-grade salivary mucoepidermoid carcinoma (MEC), and it is associated with a favorable clinical course. Primary MEC of the liver is an extremely rare, aggressive tumor, and no study has investigated CRTC1-MAML2 fusion. A 79-year-old Japanese female presented with an approx. 5-cm hepatic mass lesion. We surgically resected the lesion under the clinical diagnosis of intrahepatic cholangiocarcinoma. The histological and immunohistochemical findings were consistent with high-grade MEC, consisting of squamoid, mucin-producing, and intermediate tumor cells. Our RT-PCR analysis revealed the presence of CRTC1-MAML2 fusion. This fusion gene was further confirmed by direct sequencing. The patient is still alive almost 10 years after the surgery. This is the first case report of primary MEC of the liver with CRTC1-MAML2 fusion, with long survival. The present case has significant implications for the entity of primary MEC of the liver which should be
Introduction: Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor, however few studies have been reported in Brazilian populations. Aim: To report clinical and pathologic data from 173 head and neck MEC treated in the Treatment and Research Center at Hospital do Câncer A. C. Camargo in São Paulo. Study design: Clinical randomized. Material and Method: From 1953 to 1997, 173 cases of MEC were found in the medical files of the center. Data were obtained from the patients records and histological review of all cases. Results: The mean age of the patients was 44 years and 93 (53.8%) were men; parotid glands were affected in 61 cases (35.2%) and intraoral minor salivary glands in 75 (43.4%). TNM revealed 50.3% of the cases in stages I and II, and histological grading revealed 45.2%, 18.5% and 36.3% low-grade, intermediate-grade and high-grade tumors, respectively. Surgical treatment was employed in 80.3% of the cases, with neck dissection in 52 cases (30.1%), and ...
Diagnosis of low- or intermediate-grade tumors is associated with significantly better overall survival and disease-free survival in patients with mucoepidermoid carcinoma (MEC) of the salivary glands, while advanced disease stage and perineural invasion are the most significant indicators of poor prognosis.
Objective. It is well known that mucoepidermoid carcinoma (MEC) displays a variety of biological behaviors. While the high-grade type is a highly aggressive tumor, its low-grade counterpart usually demonstrates a more benign nature and several systems have, therefore, been proposed to grade this neoplasm.. Methods. This report analyzes 43 patients suffering from head and neck MEC, who were treated in our department during the period from 1989 to 2005. The relationship between clinical and pathologic characteristics and survival rate was investigated.. Results. The 5-year overall and disease-free survival rate was 62.3 and 57.2%. Multivariate analysis demonstrated that the parameters that significantly affected survival were the patients age (P = 0.040) and treatment method (P = 0.011).. Conclusions. The patients age and treatment method is the prognostic parameter in this study. Although complete surgical resection is the standard treatment for MEC, we should aggressively consider adjunctive ...

Mucoepidermoid carcinoma (MEC) arises from multiple organs and accounts for the most common types of salivary gland malignancies. Currently, patients with unresectable and metastatic MEC have poor long-term clinical outcomes and no targeted therapies are available. The majority of MEC tumors contain a t(11;19) chromosomal translocation that fuses two genes, CRTC1 and MAML2, to generate the chimeric protein CRTC1-MAML2. CRTC1-MAML2 displays transforming activity in vitro and is required for human MEC cell growth and survival, partially due to its ability to constitutively activate CREB-mediated transcription. Consequently, CRTC1-MAML2 is implicated as a major etiologic molecular event and a therapeutic target for MEC. However, the molecular mechanisms underlying CRTC1-MAML2 oncogenic action in MEC have not yet been systematically analyzed. Elucidation of the CRTC1-MAML2-regulated transcriptional program and its underlying mechanisms will provide important insights into MEC pathogenesis that are essential
A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid.

Hi Phil,. Thank you so much for your reply. Believe it or not, but I am STILL dealing with the pain. At one point, I was told I had shingles. However, the ENT surgeon took a biopsy which turned out to be just an ulcer. I cannot touch it. It is way far back on my soft pallete. I have to use miracle mouthwash before I eat. Sometimes I will use it in the middle of what I am eating, too. This has been going on for 5 weeks. I have lost 50 pounds (since Dec), but honestly, the weight loss is the ONLY positive thing that has come of this nightmare called cancer. I am now 147 pounds - a weight I havent seen since 1992 - ha! I miss eating. I miss pizza and subs the most. I cant eat pizza because it burns and is hard to chew (of course). Subs are impossible. I can only open my mouth to fit one finger in. I eat a lot of soups. I drink Boost (just started that) and Carnation Instant Breakfast. Im going to try what you said about adding stuff to the Carnation Instant Breakfast. I have added whey ...

4321 The 11q23 region is a common participant in LOH (Loss of Heterozygosity), observed in 40% of breast cancers, as well as leukemogenic translocations; in this study a search was made for motifs intrinsic to the region that promote recombinogenic events. The human mucoepidermoid carcinoma cell line, H292, was used for initial study on radiation-induced LOH. Here, 5 x 105 cells were exposed to either 4 or 8 Gy, surviving single cells expanded into colonies of 100 cells or more, the colonies isolated and regrown from single cells. 150 separate clones were analyzed in total. After expansion of the doubly picked clones, LOH analysis of chromosome 11 was performed using polymorphic markers at 6 locations both distal and proximal to 11q23 using a genetic analyzer. A total of 38 LOH events were observed within the irradiated groups. A hot spot for LOH was observed at 11q23.2 (Marker 744724) positive in 8/49 and 6/50 clones after 4 and 8 Gy exposure respectively. No LOH was observed centromeric to ...
This most common malignant salivary gland tumour involves minor glands, and accounts for 9.5-23% of all minor gland tumours {669,704,2711}. About half of the cases arise in the palate and other common sites include the buccal mucosa, lips, floor of oral cavity and retromolar pad. They appear to be much more frequent in the lower lip than the upper lip {1871}. The tumour is often asymptomatic and detected during a routine dental examination.Many appear as bluish, domed swellings that resemble mucoceles or haemangiomas. Less commonly, the surface appears granular or papillary. Tumours of the base of tongue or oropharynx may cause dysphagia and sublingual tumours can lead to ankyloglossia and dysphonia. High-grade tumours are uncommon but can result in ulceration, loosening of teeth, paraesthesia or anaesthesia. Mucoepidermoid carcinoma is the most common salivary gland tumour to develop in a central location within the bone of the mandible or, less frequently, the maxilla {280}. The microscopical ...

Head and Neck Cancer is a term used to describe a number of different malignant tumours that develop in or around the throat, larynx, nose, sinuses, and mouth.. Most Head and Neck Cancers are Squamous Cell Carcinomas. This type of cancer begins in the flat, squamous cells that make up the thin layer of tissue on the surface of the structures in the head and neck. Directly beneath this lining, which is called the epithelium, some areas of the head and neck have a layer of moist tissue, called the mucosa. If a cancer is limited to the squamous layer of cells, it is called Carcinoma in Situ. If the cancer has grown beyond this cell layer and moved into the deeper tissue, then it is called Invasive Squamous Cell Carcinoma.. If a Head and Neck Cancer starts in the salivary glands, the tumour will usually be classified as an adenocarcinoma, adenoid cystic carcinoma, or mucoepidermoid carcinoma. ...
Mucoepidermoid carcinoma of the lung is a rare subtype of bronchial adenoma first described 35 years ago by Smetana et al. Although initially perceived to be a slow-growing neoplasm exhibiting local but not distant spread, dissemination was later described by Ozlu et al in 1961. Widespread metastases have since been described by many authors. Of […] ...
History: Cryptotanshinone (CT) is a biologically active compound from the root of that has been reported to induce apoptosis in various malignancy cell lines; but it has not yet been fully explored in human mucoepidermoid carcinoma (MEC). of MC-3 cells results in anti-proliferative and apoptotic activities in MC-3 and it is accompanied by a decrease in phosphorylation and dimerization of transmission transducer and activators of transcription 3 (STAT3). CT decreased the expression levels of myeloid cell leukemia-1 (Mcl-1) and surviving whereas Bcl-xL expression was not changed. CT obviously regulates survivin proteins in a transcriptional alters and level Mcl-1 through proteasome-dependent proteins degradation. Furthermore CT-induced apoptotic cell loss of life in YD-15 another individual MEC cell series was from the inhibition BMS-650032 of STAT3 phosphorylation. Bottom line: These data claim that CT BMS-650032 is actually a great apoptotic inducer through adjustment of STAT3 signaling in ...

We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma ...

Immunostaining for p63, p504S and the androgen receptor status are important markers for carcinomas of the prostate. The purpose of this study was to investigate the staining characteristics of these markers for malignancies of salivary gland origin. Wax blocks of 32 malignant salivary gland neoplasms were retrieved, sections prepared and stained by the H&E method and immunoperoxidase techniques for the demonstration of p63 (Dako N1604), p504S (Dako N1609) and androgen receptors (Dako M3562). The sections were viewed by light microscopy and positivity scored with the aid of a grading scale. Androgen receptor- and p504S positivity were infrequently observed in the study samples, except for salivary duct carcinoma and mucoepidermoid carcinoma where most of the cases stained positive for p504S. The staining pattern of adenoid cystic carcinomas for p63 correlated with the microscopic subtype. The basal- and intermediate cells of mucoepidermoid carcinomas stained positive- and the mucus- and epidermoid
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether radiation therapy is more effective when given together with chemotherapy or alone after surgery in treating salivary gland tumors.. PURPOSE: This randomized phase II/III trial is studying radiation therapy with or without chemotherapy to see how well it works in treating patients with high-risk malignant salivary gland tumors that have been removed by surgery. ...

Salivary gland tumors are more likely to be cancerous in children when compared to adults. About half of the salivary gland tumors are cancerous in children. Most of the tumors occur in a salivary gland called parotid gland (located at the angle of the jaw below the ear lobes on both sides). The types of cancerous salivary gland tumors include mucoepidermoid carcinoma, adenoid cystic carcinoma, acinic cell carcinoma and adenocarcinoma NOS.. ...
This is among the first studies to evaluate patterns of M-SGC incidence in a U.S. population during 1992 to 2006 according to the WHO-2005 classification that presents a detailed evaluation of ,6,000 cases by age, gender, race, calendar year, and site. New information includes the observation that the highest IRs among males were observed for squamous cell carcinoma, mucoepidermoid carcinoma, and adenocarcinoma-NOS, whereas the predominant histologic subtypes among females were mucoepidermoid, acinic cell, and adenoid cystic carcinomas. Male-to-female IRRs varied markedly, with 14% to 23% lower incidence for acinic cell and adenoid cystic carcinoma and ∼5-fold higher IRR for squamous cell carcinoma. Mucoepidermoid and adenoid cystic carcinomas IRs were similar among Whites, Blacks, and Asians/Pacific Islanders, whereas most other histologic subtypes evaluated generally had higher IRs among Whites. Except for adenoid cystic carcinoma, which developed equally in the parotid and submandibular ...
TY - JOUR. T1 - A study on seventy-eight cases of parotid tumor. AU - Suzuki, Takahiro. AU - Ikushima, Hiroyuki. AU - Kakuta, Risako. AU - Noguchi, Naoya. AU - Ogura, Masaki. AU - Ogawa, Takenori. AU - Katori, Yukio. AU - Shoji, Fumi. AU - Ohta, Nobuo. PY - 2017. Y1 - 2017. N2 - We reviewed 78 cases of parotid gland tumors treated at our hospital over the past 2 years and 5 months. Benign tumors were observed in 65 patients (36 males and 29 females), and malignant tumors were observed in 13 patients (4 males and 9 females). The average patient age was 50 years old for the cases with benign tumors and 65 years old for the cases with malignant tumors. The most common benign tumor was pleomorphic adenoma, followed by Warthins tumor. The most common malignant tumor was mucoepidermoid carcinoma. The sensitivity/specificity/accuracy of preoperative fine-needle aspiration cytology (FNA) were 27.3%, 96.8%, and 86.5%, respectively, while those of MRI were 84.6%, 86.2%, and 85.9% when an unsharp margin ...
Discussion: Parotid gland neoplasms are quite rare in the pediatric population but when such a lesion is encountered, a higher percentage (40-50%) will be malignant when compared to the adult population (25-35%); therefore, parotid neoplasms in children must be approached with suspicion (1). The mean age at which malignant parotid gland neoplasms occur in the pediatric population is 13.2 years (2). Acinic cell carcinoma (ACC) accounts for an appreciable number of pediatric parotid malignancies; in fact, it is the second most common malignant parotid tumor in this population followed by mucoepidermoid carcinoma (3). Nasse first described the lesion in a 1892 publication in which four cases of parotid adenomas were described (4). Due to the similarity of the tumor cells to normal salivary tissue, the lesions were initially regarded as benign. The benignity of the lesion was questioned in 1953 when Buxton et al. reported three cases of ACC with verified distant metastases (5). Therefore, the lesion ...
Two patients were diagnosed with malignant tumor of the parotid gland. In the case of a 6-year-old boy with rhabdomyosarcoma (lat. rhabdomyosarcoma embryonale), ultrasound examination revealed a well-vascularized solid polycyclic lesion measuring 20x18x14 mm. After 2 weeks, MRI examination revealed a mass in the superficial and deep lobe of parotid gland measuring 53x45x41 mm, reaching parapharyngeal space, modelling the lumen of nasopharynx, and compressing internal jugular vein. The invasion of neighboring structures was not observed. In the case of an 8-year-old boy with mucoepidermoid carcinoma (lat. carcinoma mucoepidermale), ultrasound examination revealed an oval, heterogenous, hypoechogenic tumor measuring 17x13x14 mm. Ultrasound-guided fine needle aspiration (FNA) was performed, and the results were identical with subsequent histopathological examination. No further imaging studies were performed. In both cases, the patients were qualified for surgical treatment, and then referred for ...
Answer: Necrotizing sialometaplasia. Histology: The stroma surrounding the proliferation of bland squamous epithelium in this case is highly inflamed, and shows focal necrosis. The nests of squamous epithelium may appear to be invasive, but on low power have an overall lobular, branching architecture to them. Focally one may see a benign residual duct of native minor salivary gland. Significant cytologic atypia and mitotic activity are not evident. The findings are consistent with necrotizing sialometaplasia, representing squamous metaplasia of injured salivary gland ductal epithelium, typically in the setting of an ischemic insult. Discussion: Invasive squamous cell carcinoma would be highly unusual in this age group, and would demonstrate greater cytological atypia and an infiltrative growth pattern. Mucoepidermoid carcinoma could be suggested by the presence of proliferating squamous epithelium in associationwith the benign residual ducts of the minor salivary gland. The lobular nature of the ...
Ceruminous adenocarcinoma is a malignant neoplasm derived from ceruminous glands of the external auditory canal. This tumor is rare, with several names used in the past. Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), and ceruminous mucoepidermoid carcinoma. This tumor only affects the outer 1/3 to 1/2 of the external auditory canal as a primary site. If this area is not involved, the diagnosis should be questioned. The most common tumor type is ceruminous adenoid cystic carcinoma and ceruminous adenocarcinoma, NOS. Pain is the most common symptom, followed by either sensorineural or conductive hearing loss, tinnitus or drainage (discharge). A mass lesion may be present, but it is often slow growing. Imaging studies are used to define the extent of the tumor and to exclude direct extension from the parotid gland or nasopharynx. The imaging findings are usually non-specific, and cannot give a ...
