These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Papillary adenocarcinoma of the stomach with psammoma bodies: report of two cases. (1/282)

Calcification of gastric carcinoma is unusual and most of the reported cases were of the mucinous type. This report describes two cases of papillo-tubular adenocarcinoma of the stomach with psammomatous calcification confined only to the papillary portion. Calcification was so heavy that specimen X-ray was able to clearly delineate its distribution. Microscopically, the calcification was confined to the papillary carcinoma area and was not found in the area of the tubular adenocarcinoma. Polymorphic calcific bodies were found in the supportive stroma of papillae and extrapapillary spaces as concentrically laminated psammoma bodies. They were also found in tumor cells as minute corpuscles. The mechanism of neoplastic mineralization in these cases seemed different from ontogenic calcification of mucinous gastric carcinoma and we postulated the mechanism of psammomatous calcification which is referred as intracellular calcification.  (+info)

Mucin Hypersecreting Intraductal Papillary Neoplasm of the pancreas. (2/282)

Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous Cystadenoma or Mucinous Cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings help distinguish this neoplasm from the cystadenomas and cystadenocarcinomas. Histopathologic identification is not crucial to the preoperative diagnosis. This neoplasm is considered to represent a premalignant condition and, therefore, surgical resection is warranted. Prognosis, following resection, is felt to be curative for the majority of patients. We present two cases of Mucin Hypersecreting Intraductal Papillary Neoplasm and discuss their diagnosis and surgical therapy.  (+info)

Clinical significance of magnetic resonance cholangiopancreatography for the diagnosis of cystic tumor of the pancreas compared with endoscopic retrograde cholangiopancreatography and computed tomography. (3/282)

BACKGROUND: Cystic tumor of the pancreas has been investigated by a variety of imaging techniques. Magnetic resonance cholangiopancreatography (MRCP) is being widely used as a non-invasive diagnostic modality for investigation of the biliary tree and pancreatic duct system. The purpose of this study was to compare MRCP images with those of endoscopic retrograde cholangiopancreatography (ERCP) and computed tomography (CT) in order to clarify the diagnostic efficacy of MRCP for cystic tumor of the pancreas. METHODS: We retrospectively studied 15 patients with cystic tumor of the pancreas that had been surgically resected and histopathologically confirmed. There were five cases of intraductal papillary adenocarcinoma, five of intraductal papillary adenoma, two of serous cyst adenoma, two of retention cyst associated with invasive ductal adenocarcinoma and one of solid cystic tumor. RESULTS: In all cases MRCP correctly identified the main pancreatic duct (MPD) and showed the entire cystic tumor and the communication between the tumor and the MPD. On the other hand, the detection rate by ERCP of the cystic tumor and the communication between the cystic tumor and the MPD was only 60%. Although the detection rates by CT for the septum and solid components inside the cystic tumor were 100 and 90.0%, respectively, those of MRCP for each were 58.3 and 20.0%. CONCLUSION: MRCP is capable of providing diagnostic information superior to ERCP for the diagnosis of cystic tumor of the pancreas. Although MRCP may provide complementary information about the whole lesion of interest, the characteristic internal features of cystic tumor of the pancrease should be carefully diagnosed in combination with CT.  (+info)

Localized amyloidosis in canine mammary tumors. (4/282)

Histopathologic and immunohistochemical examinations were performed on localized amyloidosis associated with mammary tumors in two dogs. These tumors were identified as adenoma and adenocarcinoma. An acellular, amorphous pale eosinophilic material (amyloid) was observed in the lumina of acini lined by neoplastic cells and in the stroma of the tumors. Concentrically laminated pale eosinophilic bodies (corpora amylacea) were also found in the lumina of the acini. Amyloid and corpora amylacea stained positively with Congo red with and without 5% potassium permanganate pretreatment and revealed a green birefringence under polarized light. Corpora amylacea showed an occasional Maltese-cross pattern. Immunohistochemically, amyloid and corpora amylacea usually stained positively with anti-bovine alpha-casein antibody but negatively with anti-human amyloid AA, anti-bovine kappa-light and lambda-light chains, anti-human lactoferrin, anti-human transferrin, anti-human secretory component, and anti-human polyglucosan antibodies. These findings suggested that the amyloid deposition in these canine mammary tumors was related to lactating casein.  (+info)

Severe hypoglycaemia caused by raised insulin-like growth factor II in disseminated breast cancer. (5/282)

A 60 year old woman with disseminated ductal carcinoma of the breast developed non-islet cell tumour induced hypoglycaemia (NICTH). The concentrations of the two insulin-like growth factors, IGF-I and IGF-II, were < 2 nmol/l and 94.1 nmol/l, respectively. The IGF-II to IGF-I ratio was > 47 (normal < 10). Insulin (< 3 mu/l) and C peptide (< 100 pmol/l) were both undetectable.  (+info)

Primary carcinoma of the fallopian tube coexisting with benign cystic teratoma of the ovary. (6/282)

Primary carcinoma of the fallopian tube is a rare malignancy of the female genital tract and infrequently diagnosed before an operation. The majority of patients have extensive disease at the time of diagnosis. We have experienced incidentally a case of a carcinoma of the fallopian tube coexisting with a benign cystic teratoma of the ovary in a 25-year-old woman. We report this case with a brief review of literatures.  (+info)

Potential allogeneic graft-versus-tumor effect in a patient with ovarian cancer. (7/282)

A 33-year-old woman developed progressive ovarian cancer resistant to classical chemotherapy agents. We performed a bone marrow allograft after a myeloablative regimen. During hematological recovery, she developed acute graft-versus-host disease (GVHD). From this time her tumor diminished progressively. One year post transplant she has limited chronic liver GVHD and is still free of disease. The complete remission of advanced ovarian cancer was probably related to the GVHD which might therefore provide a new treatment option for this disease.  (+info)

Frequent activation of AKT2 and induction of apoptosis by inhibition of phosphoinositide-3-OH kinase/Akt pathway in human ovarian cancer. (8/282)

We previously demonstrated that AKT2, a member of protein kinase B family, is activated by a number of growth factors via Ras and PI 3-kinase signaling pathways. Here, we report the frequent activation of AKT2 in human primary ovarian cancer and induction of apoptosis by inhibition of phosphoinositide-3-OH kinase (PI 3-kinase)/Akt pathway. In vitro AKT2 kinase assay analyses in 91 ovarian cancer specimens revealed elevated levels of AKT2 activity (>3-fold) in 33 cases (36.3%). The majority of tumors displaying activated AKT2 were high grade and stages III and IV. Immunostaining and Western blot analyses using a phospho-ser-473 Akt antibody that detects the activated form of AKT2 (AKT2 phosphorylated at serine-474) confirmed the frequent activation of AKT2 in ovarian cancer specimens. Phosphorylated AKT2 in tumor specimens localized to the cell membrane and cytoplasm but not the nucleus. To address the mechanism of AKT2 activation, we measured in vitro PI 3-kinase activity in 43 ovarian cancer specimens, including the 33 cases displaying elevated AKT2 activation. High levels of PI 3-kinase activity were observed in 20 cases, 15 of which also exhibited AKT2 activation. The remaining five cases displayed elevated AKT1 activation. Among the cases with elevated AKT2, but not PI 3-kinase activity (18 cases), three showed down-regulation of PTEN protein expression. Inhibition of PI 3-kinase/AKT2 by wortmannin or LY294002 induces apoptosis in ovarian cancer cells exhibiting activation of the PI 3-kinase/AKT2 pathway. These findings demonstrate for the first time that activation of AKT2 is a common occurrence in human ovarian cancer and that PI 3-kinase/Akt pathway may be an important target for ovarian cancer intervention.  (+info)

Well differentiated villoglandular adenocarcinoma of uterine cervix is a rare tumour which usually occurs in young women. It is considered to be an indolent tumour with favorable prognosis and most of them were treated by conservative procedures. We report a 35 year old lady who came with complaints of 3 months amenorrhoea and an episode of spontaneous bleeding. Urine pregnancy test was negative. Physical examination revealed a cervical polyp. Histopathological findings were consistent with villoglandular papillary adenocarcinoma associated with high grade cervical intraepithelial neoplasia (CIN-3). Left parametrial and left ureteral involvement, proved by biopsy, causing left hydroureteronephrosis was detected. The patient was thus found to be in an advanced stage, stage- III b (FIGO). The patient is currently undergoing radiotherapy. A review of literature showed that only occasional cases showing disease spread have been reported, suggesting caution in the management and regular follow up of ...

Serous adenocarcinoma is a type of epithelial ovarian cancer, which is the most common among ovarian cancers. Ovarian cancers account for 6 percent of all cancers among women according to the American Cancer Society. The five-year survival rate in women with advanced ovarian cancer is 15 to 20 percent, but if the disease is found at an early stage, survival approaches 90 percent [16]. Women with a personal/family history of ovarian or other cancers are at the highest risk of having ovarian serous carcinoma, especially if their mother or sister had ovarian cancer. Other risk factors include: increased age, use of high-dose estrogens without progesterone for a long period, uninterrupted ovulation due to infertility, no pregnancies, no use of birth control, and defects in the BRCA1 or BRCA2 genes. Unfortunately, in most women ovarian serous carcinoma is not diagnosed until the disease is advanced, and has spread into the abdomen or beyond due to non-clear physical symptoms. Therefore, early ...

The NCI-H441 cell line was derived by A.F. Gazdar, M. Brower and D. Carney and associates in 1982 from the pericardial fluid of a patient with papillary adenocarcinoma of the lung.
Micropapillary carcinoma (MPC) is a rare variant of carcinoma, and it is composed of small papillary neoplastic cell clusters lying within clear lacunar spaces that simulate lymphovascular channels. This tumor has been described in the several organs such as the breast, lung, urinary bladder and salivary gland and it is known to be frequently associated with a high incidence of lymphatic invasion and metastasis in lymph nodes, resulting in poor clinical outcome. We present here a case of MPC in the gall bladder, and this type of case has not been previously described. Histologically, the tumor was composed of micropapillary carcinoma with tight clusters of micropapillary aggregates in the background of tubular adenoma. Focal invasive micropapillary components were also noted in the submuscular connective tissue. A metastatic lesion in a regional lymph node also showed an entirely micropapillary pattern. ...

Papillary thyroid carcinoma (PTC) is the most common type of well-differentiated thyroid carcinoma and typically has an excellent prognosis. The incidence of distant metastasis from PTC is low. However, once metastasis has developed in a distant site, prognosis is markedly diminished. Brain metastases from PTC are extremely rare. No consensus regarding management has yet been reached. We report on the case of a patient who presented with signs of intracranial hypertension. Cranial magnetic resonance imaging (MRI) identified a lesion of the right temporofrontoparietal lobe. The patient underwent a craniotomy with a total removal of the tumor. Histologic examination of the lesion showed a metastasis of papillary adenocarcinoma. We observed a cold nodule in the right lobe of the thyroid on physical examination and imaging techniques (e.g., CT and scintigraphy). Fine-need-aspiration cytology of the nodule was reported as PTC. A total thyroidectomy was performed and histopathological examination ...

The transcriptional regulator c-Myc is the most frequently deregulated oncogene in human tumors. Targeted overexpression of this gene in mice results in distinct types of lung adenocarcinomas. By using microarray technology, alterations in the expression of genes were captured based on a female transgenic mouse model in which, indeed, c-Myc overexpression in alveolar epithelium results in the development of bronchiolo-alveolar carcinoma (BAC) and papillary adenocarcinoma (PLAC). In this study, we analyzed exclusively the promoters of induced genes by different in silico methods in order to elucidate the c-Myc transcriptional regulatory network. We analyzed the promoters of 361 transcriptionally induced genes with respect to c-Myc binding sites and found 110 putative binding sites in 94 promoters. Furthermore, we analyzed the flanking sequences (+/- 100 bp) around the 110 c-Myc binding sites and found Ap2, Zf5, Zic3, and E2f binding sites to be overrepresented in these regions. Then, we analyzed the
The objective of this study was to investigate the relationship between the accumulation of black dust matter in lungs (anthracosis) and primary lung cancer in dogs. A retrospective study was carried out on material from 35 dogs with primary lung cancer and 160 controls. The amount, histological appearance and birefringence of anthracosis were assessed in pulmonary specimens by light microscopy, and the odds ratio (OR) calculated for dogs with primary lung cancer. The same factors were analysed to identify an association between tumour histotype, histological grade, and clinical stage. Papillary adenocarcinoma was most commonly diagnosed (45.7%). The majority of tumours were of histological grade II, and the lung cancer was more often localised (clinical stage I). An increased risk of lung cancer was observed in dogs with higher amounts of anthracosis (OR: 2.11, CI 95%: 1.20-3.70; P , 0.01), which suggests an association between anthracosis due to inhalation of polluted air and lung cancer in ...

Three out of four patients with extrapancreatic invasion died of their tumors or ...
A psammoma body is a round collection of calcium, seen microscopically. The term is derived from the Greek word ψάμμος (psámmos), meaning sand. Psammoma bodies are associated with the papillary (nipple-like) histomorphology and are thought to arise from (1) the infarction and calcification of papillae tips and (2) calcification of intralymphatic tumor thrombi. Psammoma bodies are commonly seen in certain tumors such as: Papillary thyroid carcinoma Papillary renal cell carcinoma Micropapillary subtype of lung adenocarcinoma Ovarian papillary serous cystadenoma and cystadenocarcinoma Endometrial adenocarcinomas (Papillary serous carcinoma ~3%-4%) Meningiomas, in the central nervous system Peritoneal and Pleural Mesothelioma Somatostatinoma (pancreas) Prolactinoma of the pituitary ...

N2 - Psammoma bodies at the perivascular area in five cases of meningioma were examined with the electron microscope. In general, meningocytic cells invest the outer aspect of blood vessels, which are constituted by multilayered basal laminae, collagen fibers, microfibrils, and pericytes. Remnants of degenerated cells are observed in some areas of the perivascular space. Matrix vesicles and matrix giant bodies with or without mineralized deposits are also present in those areas. Energy disperisve, X-ray microanalysis evidenced the presence of both calcium and phosphorus (probably hydroxyapatite) mineralized precipitates. Production of psammoma bodies in the perivascular area may indicate that matrix vesicles and matrix giant bodies are derived from degenerated cells, which then sequestrate ...

Intraductal papillary mucinous neoplasms of the pancreas: an increasingly recognized clinicopathologic entity.: Intraductal papillary mucinous neoplasms represe
Oviduct-specific glycoprotein is a glycoprotein secreted by secretory epithelial cells of the oviduct (3) ; recently, we showed that it is ectopically expressed in ovarian cancer (9) . On the basis of the present study of normal, hyperplastic, and malignant endometrial tissues, it appears that a gain of oviduct-specific glycoprotein begins under conditions of unopposed estrogen exposure, which is a known risk factor for the development of endometrioid carcinoma.. Although oviduct-specific glycoprotein is not normally a secretory product of the normal endometrium, we observed focal staining of the stem cells in the basalis layer with some staining in adjacent glands in the functionalis layer (1) .

N2 - Inherited loss-of-function mutations in BRCA1 and BRCA2 and other tumor suppressor genes predispose to ovarian carcinomas, but the overall burden of disease due to inherited mutations is not known. Using targeted capture and massively parallel genomic sequencing, we screened for germ-line mutations in 21 tumor suppressor genes in genomic DNA from women with primary ovarian, peritoneal, or fallopian tube carcinoma. Subjects were consecutively enrolled at diagnosis ...
Fallopian tube carcinomas were once believed to be rare. Some investigators have demonstrated precursor cancerous lesions in the fallopian tube (tubal in-situ carcinoma [TIC]) and have speculated that many advanced serous

The question as to whether BRAF confers a distinct biological behaviour to PTC that could have a prognostic value is still controversial. The inconsistent results described by several groups (Soares et al. 2003, Xu et al. 2003, Fugazzola et al. 2004, Trovisco et al. 2005) could be partially due to an insufficient number of patients and/or to the different combinations of various subtypes of PTC included in each study. Subtype stratification is likely to be important as BRAF is present predominantly in the classic and tall cell variants of PTC and not in the follicular variant. In our study, with classic PTC accounting for more than 50% of the total, BRAF mutation predicted an increased risk of recurrence. The univariate analysis also revealed that BRAF was associated with extra-thyroidal extension and advanced clinical stage. Indeed, larger series including mortality rate and multivariate analysis with adjustment for various confounding factors will reveal the independent prognostic role of ...
The 5-year overall survival and recurrence-free rates were 86.8% and 84.8%, respectively. During follow-up, 59 (7.9%) patients developed recurrence. Univariate analysis showed that micropapillary/solid predominant group had significantly lower probability of FFR (P = 0.001) in node-negative lung adenocarcinoma of 3cm or smaller. Older age (P = 0.007), greater tumor size (P = 0.006), and micropapillary/solid predominant group (P = 0.031) had significantly lower probability of FFR in multivariate analysis. ...
