Histopathologic features and management of ameloblastoma: study of 20 cases. (1/137)

BACKGROUND: Odontogenic ameloblastoma (OA) of the jaws is a rare neoplasia of the oral cavity (0.78%) with a 5:1 mandible/maxilla relation, with the molar region and the ascendant ramus being the most affected areas. Comparing our results with the literature demonstrated to us that this tumor may be considered to be a worldwide problem due to the similarity in clinical findings among different ethnic groups CASE SERIES: The purpose of this study of 20 patients with ameloblastoma of the mandible and maxilla diagnosed at the Stomatology and Head and Neck Services of Heliopolis Hospital, Sao Paulo, Brazil, from 1980 to 1997, was to establish the histopathologic pattern of classification of those tumors through optical microscopy and the relation of this histopathology to therapeutic management. Using the Regeze, Kerr and Courtney classification (1978), we diagnosed follicular tumor in 11 cases, plexiform in 6 cases and unicystic in 3 cases, and performed surgical resection with a safety margin of 1.5 to 3.0 cm in the follicular and plexiform cases and bone curettage in the unicystic cases.  (+info)

Extra copies of chromosomes 7, 8, 12, 19, and 21 are recurrent in adamantinoma. (2/137)

Adamantinoma of long bones is a rare neoplasm predominantly involving the tibia. Cytogenetic studies of adamantinoma are few. Cytogenetic or molecular cytogenetic analysis of four adamantinomas, and a review of eleven cases in the literature reveals extra copies of chromosomes 7, 8, 12, 19, and 21 as recurrent in this neoplasm. Adamantinoma may be confused with a variety of primary and metastatic epithelial and mesenchymal neoplasms. Observation of these aneuploidies may be useful in establishing the diagnosis of adamantinoma.  (+info)

Clinicostatistical study of ameloblastoma treatment. (3/137)

The purpose of this study was to investigate the treatment of 190 cases of ameloblastoma in our department from 1966 to 1994. The statistical results with regard to age, sex and region agreed with those of other investigators. Thirty-five of 43 (81.4%) cases underwent enucleation in 1960s, but the sixteen of 27 (59.3%) cases underwent partial resection of mandible in 1990s. The defect of mandible was reconstructed with iliac bone grafting since 1968, grafts with a mixture of iliac blocked bone and PCBM (particulate cancellous bone and marrow) have been used since 1975. Grafting of the inferior alveolar nerve with the great auricular nerve to the defect has been performed in our department since 1977. Recently, technique involving pull-through of the inferior alveolar nerve bundle has been used in our department. When the reconstruction method for the mandible and nerve has been established, it becomes possible to operate radically and positively. Recurrence occurred in 17 cases after the primary enucleation. It is thought that the primary treatment of ameloblastoma must be as radical as possible. It appears to be necessary to observe progress and perform follow-up in cases of ameloblastoma for more than ten years, because there was one recurrence at 9 years and 4 months after the first operation. In fact, three quarters of our cases were lost to follow-up. Such losses can problems in confirming recurrence and responding rapidly.  (+info)

Cytokeratins expression of constituting cells in ameloblastoma. (5/137)

The purposes of this study were to investigate the distribution of cytokeratins in the different tissue types of ameloblastoma and to discuss the histogenesis of this tumor. CK19 and CK8, which are markers for odontogenic epithelium, reacted positively to the constituting cells in all types of ameloblastoma. This suggests that all types of ameloblastoma derive from odontogenic epithelium. However, the desmoplastic type diminished the odontogenic characteristics because the basal cells are negative to CK19. Immunoreactions of five kinds of cytokeratin revealed similar results in plexiform, follicular, acanthomatous, and granular cell types. The plexiform type is probably the original type of ameloblastoma; the other types have the characteristics of squamous epithelium, and the follicular, acanthomatous, and granular cell types can develop due to the differentiation of cells of the plexiform type into squamous epithelium.  (+info)

Hemicortical allograft reconstruction after resection of low-grade malignant bone tumours. (6/137)

Low-grade surface tumours of bone may theoretically be treated by hemicortical resection, retaining part of the circumference of the cortex. An inlay allograft may be used to reconstruct the defect. Since 1988 we have performed 22 hemicortical procedures in selected patients with low-grade parosteal osteosarcoma (6), peripheral chondrosarcoma (6) and adamantinoma (10). Restricted medullary involvement was not a contraindication for this procedure. There was no evidence of local recurrence or distant metastasis at a mean follow-up of 64 months (27 to 135). Wide resection margins were obtained in 19 patients. All allografts incorporated completely and there were no fractures or infections. Fractures of the remaining hemicortex occurred in six patients and were managed successfully by casts or by osteosynthesis. The functional results were excellent or good in all except one patient. Hemicortical procedures for selected cases of low-grade surface tumours give excellent oncological and functional outcomes. There was complete remodelling and fewer complications when compared with larger intercalary procedures. The surgery is technically demanding but gives good clinical results.  (+info)

Malignant odontogenic tumors. A retrospective and collaborative study of seven cases. (7/137)

The frequency, clinico-pathologic features and outcome of malignant odontogenic tumors diagnosed according to the current WHO classification in three pathology services in Mexico City are presented. There were seven cases (5 male and 2 female patients), which represent less than 4% of all odontogenic tumors diagnosed in these services. There were six odontogenic carcinomas (two malignant ameloblastomas, two clear cell odontogenic carcinomas, one primary intraosseous carcinoma and one carcinoma arising in an odontogenic cyst) and one ameloblastic fibrosarcoma. Age ranged from 25 to 72 years (mean: 43.8). Clear cell odontogenic carcinomas occurred in the canine-premolar region, one in the maxilla and one in the mandible (one ia a man and one in a woman), while the remaining lesions affected the posterior region of the mandible, with a male predominance (4:1), which agrees with previously reported cases. Surgical resection was the treatment employed in all carcinomas, while the ameloblastic fibrosarcoma was treated with chemotherapy due to its large extension, but without favorable response. The patient with primary intraosseous carcinoma had submaxillary and cervical metastases and the neoplasm was the cause of death. In spite of their extremely low frequency, malignant odontogenic tumors are an important cause of extensive surgical procedures in the oral and maxillofacial region.  (+info)

Ameloblastic fibroma of the mandible. Report of two cases. (8/137)

The ameloblastic fibroma (AF)-ameloblastic fibro-odontoma (AFO), is an uncommon benign mixed odontogenic tumor (epithelial and mesenchymal), that represents the 2% of all odontogenic tumors. It usually appears in the mandible and in the posterior segments of young patients without gender predilection, and sometimes is associated with an impacted tooth. The classification of the WHO includes it in the subtype of odontogenic tumors with a defined histologic features. The AF and the AFO are considered as an unique entity as they are variations of the same tumor, only distinct for the presence of an odontoma in the case of the AFO. Surgical conservative treatment with excision followed by curettage seems to be the most appropriate therapeutic option. The objective of this paper is to report two cases of this tumor, to make a brief review of the literature and its differential diagnosis, to analyse its clinical and histologic features and the therapeutic option.  (+info)

Ameloblastoma is a histologically almost always benign odontogenic tumor with a high rate of recurrence if not removed completely. Therefore, radical surgery is the treatment of choice of a primary ameloblastoma. Of 18 patients with a recurrent ameloblastoma, previously treated by enucleation, radical surgery was deemed impossible in three because of the extent of the tumor or because of a poor general condition of the patient. Of the remaining 15 patients three refused to undergo radical surgery and have been treated for their recurrence by enucleation again ...

INTRODUCTION: Cases of maxillary ameloblastomas from 15-year database (1986-2000) collected in the Department of Cranio-Maxillofacial Surgery of the University Hospital of Zurich were evaluated. PATIENTS: Twenty-six patients suffering from ameloblastoma had been collected. Five of them, had a maxillary ameloblastoma, three females and two males. METHODS: A clinical retrospective study was performed. In addition a review of the literature was undertaken and the findings have been compared and contrasted. PATIENTS: The overall incidence of ameloblastoma within the mandible (21) was four times higher than in the maxilla (5). In 69 per cent of the cases (18) it occurred in men, in 31 percent (8) in women. The sex ratio differed with the maxillary ameloblastomas: 40 percent male (2) and 60 per cent female (3). Although slow growing and nearly painless, it can reach a considerable size within the mid-face involving such highly specialized structures as the orbit, skull-base and brain. Wide resections ...

Ameloblastoma (from the early English word amel, meaning enamel + the Greek word blastos, meaning germ) is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. It was recognized in 1827 by Cusack. This type of odontogenic neoplasm was designated as an adamantinoma in 1885 by the French physician Louis-Charles Malassez. It was finally renamed to the modern name ameloblastoma in 1930 by Ivey and Churchill. While these tumors are rarely malignant or metastatic (that is, they rarely spread to other parts of the body), and progress slowly, the resulting lesions can cause severe abnormalities of the face and jaw. Additionally, because abnormal cell growth easily infiltrates and destroys surrounding bony tissues, wide surgical excision is required to treat this disorder. If an aggressive tumor is left untreated, it can obstruct the nasal and oral airways making it ...

With the disease being extremely rare, clinicians have to rely on various reported cases for guidance. Hence, the establishment of treatment standards is not possible. Radiotherapy has been controversially discussed in the past. Most reported cases underwent surgical removal.. Reports of ameloblastic carcinomas receiving radiation therapy are scarce and mostly from the pre-3 D and cobalt era [9-11]. To our knowledge, radiotherapy has only been given as adjuvant therapy in only a few cases [11-15] within the past 20 years. Radiation doses between 41,4 Gy and 54 Gy have been comparatively conservative [12, 13, 16] or not been reported [2, 14, 17] leading to local relapse in half of the cases. Higher radiation doses between 66 and 72 Gy in close margin/positive-margin resections as reported by Philip et al [15] lead to local control for the duration of available follow-up (0.8 - 3.3 years) in the reported 3 cases.. While it has been discussed in cases with incomplete resections or nodal metastases, ...
Ameloblastomas are odontogenic tumors known for their aggressive nature. Because of the odontogenic origin, they are seen affecting the mandible and maxilla. Like humans, animals like dogs, horses may also develop these lesions. In this report, ameloblastoma of the mandible in a male dog is described, The lesion clinically appeared like an exophytic growth on the gingiva near mandibular left canine tooth, radiograph showed a large multilocular radioleucency with destruction of the lower mandible. The lesion recurred after 2 years following the conservative removal. This case report is interesting because similar to humans, the dogs too suffer from the odontogenic lesions. The radiographic, histologic features and the behaviour pattern were similar to humans where as the treatment rendered was only conservative keeping the limited life span of the dog.

Bilateral rostral mandibulectomy is a surgical procedure involving removal of the mandible rostral to the second premolar tooth. This technique is indicated for benign oral tumors, such as acanthomatous ameloblastoma and either small or low-grade malignant tumors, which have crossed the midline.. The overall complication rate following bilateral rostral mandibulectomy in dogs is 19%. The most common complications are wound dehiscence (2%-8%) and short-term eating difficulties (up to 44% overall with 30%, 70%, 90%, and 97% of dogs returning to voluntary eating by day 1, 2, 3, and 4, respectively). The median time to return to voluntary eating is 2 days following bilateral rostral mandibulectomy in dogs. In one study, prehension difficulties were common following bilateral rostral mandibulectomy, particularly with more aggressive procedures extending caudal to the second premolar teeth because of the loss of bone and soft tissue support of the tongue; however, the majority of dogs with prehension ...

Bilateral rostral maxillectomy is a surgical procedure involving removal of the maxilla rostral to the second premolar tooth. This technique is indicated for benign oral tumors, such as acanthomatous ameloblastoma and either small or low-grade malignant tumors, which have crossed the midline.. The most common complications following biilateral rostral maxillectomy include cosmetic appearance and wound dehiscence (7%-33% overall). Cosmetically, the nose droops downwards because of loss of ventral support from the incisive and maxillary bones. While this is a cosmetic defect and rarely causes functional problems, such as respiratory difficulties; it can be corrected with a cosmetic cantilever nasal lift surgery. Functionally, dogs and cats do well following bilateral caudal maxillectomy with the vast majority of animals returning to voluntary eating within 1-3 days of surgery. In a 1997 survey of owner satisfaction, 85% of owners were satisfied with the functional and cosmetic outcomes following ...
appointment day had arrived, just two weeks later, the area in question had doubled in size and was now a visible mass. It was decided that during her dental procedure, the mass should be removed and sent off to a lab for further testing. The removal of the growth involved the extraction of Stellas four lower front teeth in order to make it possible to get as much of the invasive tissue as possible. The days to follow came with good and bad news. Lab results revealed that the tumor was benign and non-cancerous. This was certainly a relief to her caregivers. However, pathology test results showed that this type of tumor was a locally aggressive and rapidly growing mass of cells known as Canine Acanthomatous Ameloblastoma (CAA), which would be very hard to completely obliterate without a more invasive form of surgery. We also learned that the margins along the specimen removed from her mouth were not clear - meaning that this type of cellular formation still probably existed deep within the ...

Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic neoplasm of the jaw. AFS is characteristically composed of a benign odontogenic epithelium and a malignant mesenchymal component. The posterior region of the mandible is the predominantly occupied site. In the present report, a new case of AFS in a 22-year-old male that originated from ameloblastic fibroma was described. Histologically, the tumor showed biphasic components: Benign epithelium and a malignant mesenchymal component. Immunochemical findings revealed that the tumor cells were positive for cluster of differentiation (CD) 34, vimentin, Ki-67 and p53, but negative for smooth muscle actin, S-100, CD68 and desmin ...

Based on its histological resemblance to some odontogenic tumors, we suspected the presence of common genetic alterations among these tumors. To address this issue, 11 cases of calcifying odontogenic cyst (COC) and 20 cases of ameloblastoma were investigated for the presence of β-catenin mutations and β-catenin expression. Ten COCs were successfully analyzed by direct sequencing, and nine of them were found to harbor somatic β-catenin mutations. Immunohistochemically, all of the ...
Non-inflammatory odontogenic cysts and tumours vary in clinical appearance and can cause widespread destruction and deformation of the face. Proteases may play a role in the differing pathogenesis of these cysts and tumours. Human kallikrein proteins (KLKs) are a group of 15 serine proteases implicated in a variety of signaling and regulatory roles. This study evaluated the ameloblastoma, keratocystic odontogenic tumour (KOT), dentigerous cyst, lateral periodontal cyst, nasopalatine duct cyst and odontoma for the presence of KLK 3, 4, 5, 9 and 11 utilizing immunohistochemistry. Secondarily, we evaluated ameloblastoma for expression of KLK 1-15 mRNA using reverse transcription-polymerase chain reaction. Immunostaining identified KLK 3, 4, 9 & 11 in all tissue types and KLK 5 only in KOTs. The ameloblastoma expressed KLK 1, 4, 7, 8, 10 & 12 mRNA. For the first time KLK 3, 4, 5, 9 & 11 were identified in maxillofacial cysts and tumours.

INTRODUCTION. The human homologue of Drosophila patched (PTCH) is a tumor suppressor gene localized to chromosome 9q22.3-q31 (GenBank accession numbers: U43148 and U59464) (Hahn et al., 1996; Johnson et al., 1996) member of the Hedgehog/Patched (or SHH/SMO/PTCH) signaling pathway, which plays a fundamental role during embryogenic development and appears to underlie many disease states when misregulated (Saldanha, 2001). Increased PTCH expression has been detected immunohistochemically in sporadic and Gorlin-syndrome-related keratocystic odontogenic tumors (Barreto et al., 2000; Ohki et al., 2004; Shear, 2002; Zedan et al., 2001), dentigerous cysts (Levanat et al., 2000), ameloblastomas (Kumamoto et al., 2004) and epithelial-mesenchymal tumors, such as adenomatoid odontogenic tumor, Pindborg tumor and ghost cell odontogenic carcinoma (Zhang et al., 2006). However, to the best of our knowledge, there are no studies concerning the PTCH in dental follicles (DF), whose epithelial components are ...
To the authors knowledge, this is the first reported case of an odontogenic carcinoma with documented skeletal muscle differentiation (rhabdomyosarcoma). The histology and clinical features of this aggressive odontogenic neoplasm are described. Within the English-language literature, only 2 cases are reported of an odontogenic tumor with muscle differentiation: a benign odontogenic tumor (ameloblastoma) with differentiation into a rhabdomyosarcoma and an odontogenic sarcoma with smooth-muscle differentiation. The general practitioner should be aware that odontogenic lesions may be malignant, even though this is extremely rare, and all tissue removed from the oral cavity should be submitted for biopsy.

During the last few years several studies have been published dealing with the immunhistological properties of AOT. Immunohistochemically, the classical AOT phenotype is characterized by a cytokeratin (CK) profile similar to follicular cyst and/or oral or gingival epithelium based on positive staining with CK5, CK17 and CK19 [18]. On the other hand the classical AOT is negative for CK4, 10, 13 and 18. Recently, Crivelini et al. [19] detected the expression of cytokeratin 14 in AOT and concluded that this probably indicate its origin in the reduced dental epithelium which is also positive for staining with cytokeratin 14 antibodies. Positive reactions for amelogenin in limited areas in AOT are also reported as well as in ameloblasts and in the immature enamel matrix [20].. Interestingly, Takahashi et al. [21] observed a positive staining for iron-binding proteins (transferring, ferritin) and proteinase inhibitor (alpha-one-antitrypsin) in various cells of AOT indicating their role to the ...
Objective: To study hTERT mRHA expression in ameloblastoma (AB) and odontogenic keratocyst (OKC) and to investigate the genesis, development and biological characteristics of AB and OKC. Methods: hTERT mRNA expression in 54 cases of AB, 16 cases of OKC, and 7 cases with normal oral mucosa was detected by in situ hybridization. Results: The positive ratios of hTERT mRNA in AB, OKC and normal oral mucosa were 94.4% (51/54), 87.5% (14/16) and 14.3% (1/7) respectively. There was a significant statistical difference (P < 0.001). hTERT has no correlation (P > 0.05) with histological types, lesion locations or types of AB growth (unilocular or multilocular). hTERT mRNA was found in peripheral and stellate reticular cells, but not in keratinizing and degraded areas or granular cells.

Case study: In May 2016, a 60-year-old male patient was referred with a swelling in the premolar/molar region of the left mandible This had been preceded by an operation to remove tooth 38, carried out by a registered oral surgeon. As the spongiosa in the vicinity of tooth 38 seemed conspicuously soft to the surgeon, he prescribed a histopathological examination. This found fibrotic tissue, giant cells, and reactive new bone formation with signs of active remodelling. Any malignant process was expressly ruled out, as was an ameloblastoma. We for our part prescribed three-dimensional imaging using CT, and the finding was a tumorous infiltration of ramus and corpus mandibulae. Another biopsy, carried out with intubation anesthesia, was interpreted in the histopathological finding as a moderately differentiated squamous cell carcinoma. There followed the partial resection of the mandible with a joint replacement and neck dissection on one side. The histopathological finding classified the ...

Background: Oral cancers (OC) are malignant lesions occurring in the oral cavity that include squamous cell carcinomas (SCC), salivary gland and odontogenic neoplasms. Even though it is the eighth most common malignancy globally but in Pakistan it is the second commonest type of cancer. Lack of awareness about ill-effects of preventable risk factors of oral cancer increases the burden of disease due to the associated high cost of treatment, permanent impairment and high mortality. Hence, awareness can be very helpful in prevention, control and early diagnosis of oral cancer. Methods: A cross-sectional study was carried out among university students from Karachi, Pakistan during April to May 2018. Three hundred students were approached to participate in the study of which 277 agreed to participate. Pretested questionnaire was distributed and collected data was analysed using IBM SPSS version 23. Results: There were 125 (45%) males and 152 (55%) females in the study and response rate was 94%. ...

Najpogostejša vrsta (60 %) napadov so krčeviti, konvulzivni napadi.[15] Od tega jih dve tretjini začne kot žariščni napadi (ki se potem lahko spremenijo v generalizirane napade), ena tretjina med njimi pa se pojavi kot generalizirani napad.[15] Preostalih 40 % napadov je nekonvulzivnih. Primer te vrste je odsotnostni napad, ki se kaže kot zmanjšana raven zavesti in po navadi traja okoli 10 sekund.[16][17]. Pred žariščnim napadom pride pogosto do določenih doživetij, ki so znani kot avra.[18] Gre med drugim za čutilne (vidne, slušne ali vonja) doživljaje, ter psihične, avtonomske ali motorične fenomene.[16] Trzljaji se lahko začnejo v določeni skupini mišic in se potem razširijo na okoliške skupine mišic, proces, znan kot Jacksonski pohod.[19] Lahko pride do avtomatizmov; gre za nezavestno izzvane dejavnosti, ki so večinoma enostavni, ponavljajoči se gibi, kot je cmokanje, ali pa gre za bolj zapletene gibe, kot je pobiranje kake stvari s tal.[19].

V raziskovanju in teoretiziranju ženskega orgazma vlada polemika o vlogi in funkciji ženskega orgazma, saj je za razliko od moškega, funkcija ženskega orgazma veliko bolj nejasna, pri čemer se pojavljajo spekulacije o njegovi funkciji pri »posrkanju semena«. Na nasprotnih polih nastopajo zagovorniki teorije ženskega orgazma kot posledice adaptacije skozi evolucijo in zagovorniki ženskega orgazma kot evolucijsko stranskega produkta moškega orgazma. Adaptacija pomeni, da se na primer nek organ ali lastnost skozi evolucijo razvije tako, da poveča svojo učinkovitost, kar pomeni, da ima ta lastnost za organizem nekakšno funkcijo. Zaradi tega zagovorniki ženskega orgazma kot adaptacije verjamejo, da ima ta funkcijo. Na drugi strani zagovorniki ženskega orgazma kot stranskega produkta moškega orgazma pravijo, da ženski orgazem nima funkcije in je zgolj neke vrste ostanek skupnega zgodnjega embrionalnega razvoja z moškimi, pri katerih ima orgazem reproduktivno funkcijo.

A keratocystic odontogenic tumour (also keratocystic odontogenic tumor), abbreviated KCOT, is a rare and benign but locally aggressive developmental cystic neoplasm. It most often affects the posterior mandible.. It was previously called odontogenic keratocyst and abbreviated OKC. ...
Background/Aim: In the pathogenesis of odontogenic tumors which arise from the rests of the dental apparatus in the jaw, several molecular pathways have been shown to play critical roles such as genetic alterations in the hedgehog, BRAF/Ras/MAPK, epidermal growth factor receptor. Next generation genomic sequencing has identified gene mutations in many different tumors. Materials and Methods: Here we report four types of odontogenic tumor including six cases in which five had mutation according to next generation sequencing analysis from archival paraffin blocks that diagnosed previously as ameloblastoma (solid), amloblastoma (unicystic-mural), ameloblastic fibroma, squamous odontogenic tumor, and adenomatoid odontogenic tumor. Results: All ameloblastomatic tumors were shown BRAF mutation and adenomatoid odontogenic tumors were KRAS mutation. Conclusion: This evidence may highlight the poorly understood pathogenesis of odontogenic tumors. Further comparisons need to be made with other benign and ...
Objective: In jawbones, ameloblastomas and odontogenic keratocysts share many clinical features in common such as aggressiveness, high recurrence rates and radical management options. Understanding the pathogenesis and biological aspects of these tumors would improve the success of diagnose and treatment procedures. The aim of this study was to exhibit the reasons of high recurrence rates and growth potentials of ameloblastomas and keratocystic odontogenic tumours by investigating the expression of IL-1? and IL-6 and IL-1? -889 gene polymorphism. IL-1? and IL-6 are shown as very effective tissue degrading factors in bone remodelling. Study Design: This study included 25 cases of ameloblastomas, 41 cases of keratocystic odontogenic tumors (parakeratinized odontogenic keratocysts) and 8 cases of orthokeratinized odontogenic keratocysts. All histological slides were stained immunohistochemically to show the expression of IL-1? and IL-6. Restriction fragment length analysis was used to investigate ...
An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible. It most commonly presents in the third decade of life.[1]. In the WHO/IARC classification of head and neck pathology, this clinical entity had been known for years as the odontogenic keratocyst; it was reclassified as keratocystic odontogenic tumour (KCOT) from 2005 to 2017.[2][3] In 2017 it reverted to the earlier name, as the new WHO/IARC classification reclassified OKC back into the cystic category.[4] The WHO/IARC classification no longer considers it a neoplasm, because the evidence supporting that hypothesis (for example, clonality) is considered insufficient. However, this is an area of hot debate within the head and neck pathology community, and some pathologists still regard OKC as a neoplasm despite the reclassification.. ...

Summary: The calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare lesion that represents 1% of odontogenic tumors, although their histogenesis is unknown, the cells that constitute it are derivative of the intermediate layer body enamel. This type of tumor has been found in patients ranging in age from 30 to 50 years of age without gender predilection, and usually located in posterior mandible, sometimes associated with impacted third molars. Among its most common features present slow, progressive and asymptomatic growth, these lesions usually are discovered by the mandibular asymmetry that can potentially cause. Radiographically the tumor appears as a radiolucency with scalloped margins unilocular or multilocular nature, which may contain defects calcified structures with variable size and density, and sometimes containing radiopaque focus, where the treatment of choice is local resection, which results with good prognosis. While CEOT is an uncommon ...
INTRODUCTION: Ameloblastic fibro-odontosarcoma is an extremely rare subtype of odontogenic sarcoma, with only 13 cases reported in the literature.. CASE REPORT: A 4-year-old male presented with a painless mandibular swelling, which appeared 4months previously. Cone beam computed tomography revealed an extensive, ill-circumscribed, multilocular radiolucency of the right mandible extending from the first deciduous molar to the ramus with slightly dense opacities. Histological examination of the incisional biopsy specimen revealed a biphasic tumor with sarcomatous mesenchyme and benign ameloblastic epithelial component compatible with a diagnosis of ameloblastic fibrosarcoma. A right hemimandibular resection was performed. Areas of deposition of dentinoid and enamel material closely adjacent to ameloblastic epithelium were noted in the excised specimen. A final diagnosis of ameloblastic fibro-odontosarcoma was made. After four years of close follow-up, there is no sign of recurrence or ...

Cyclooxygenase-2 (COX-2) levels are increased in various tumors, particularly those involving the esophagus, stomach, breast, pancreas, lung, colon, skin, urinary bladder, prostate and head and neck. Nevertheless, the tumorigenic mechanisms of COX-2 overexpression still remain poorly understood and may include mechanisms that may act at different stages of the disease. Thus, the literature shows increasing evidence that overexpression of the COX-2 plays an important role in tumor growth and spread of tumors by interfering with different biological processes such as cell proliferation, cellular adhesion, immune surveillance, apoptosis, and angiogenesis. Furthermore, the expression of COX-2 might shed some light over the physiopathology and clinical behavior of tumors of the head and neck, including benign odontogenic neoplasms of the jaws with an aggressive behavior, such as keratocystic odontogenic tumors (KCOT). Ultimately, the research of molecular markers associated with the biological ...
About 200 cases of MNTI have been reported until now. It is found to characteristically occur in the maxilla, more so from the intraoral side. Bone destruction and displacement of teeth often occur because of the intraosseous location in the maxilla. Other sites are the skull, mandible and the brain. The lesion is usually solitary and the mucosa over the lesion is usually intact. It has got a typical bluish color due to the presence of melanin. Although it is a benign tumor with a 2% chance of malignancy, it is locally aggressive. The majority of MNTI patients (there is no sexual predilection) present in the 1 year of life. The children present with swelling in the oral cavity, which often hinders feeding. The differential diagnosis is ameloblastoma, odontoma, odontogenic myxoma, fibroma, rhabdomyosarcoma, EwingÌs sarcoma, LangerhansÌ cell histiocytosis (LCH), non-HodgkinÌs lymphoma ...

ABSTRACT. The myofibroma is a tumor that presents predominantly in head and neck, oral cavity are rare and even more intraosseous; in the mandible represent 12% of all soft tissue tumors in children. The presence of this injury is rare, affecting children and young people, it is noteworthy that in the mandible are even less frequent. Histopathologically looks similar to a hemangiopericytoma. The definitive diagnosis is based immunohistochemical panel consisting of antibodies to vimentin, dismina, CD34, HHP-35, SMA and S-100 P; giving positive vimentin and HHF-35 dismina with marker muscle actin smooth for the identification of myofibroblasts. Objective: Retrospective, longitudinal, observational study, from three cases of pediatric patients. Discussion: Intraosseous mandibular myofibroma is a rare tumor that only occurs in childhood, clinical and radiological features may suggest a presumptive diagnosis of ameloblastoma or myxoma, while histopathological diagnosis can be confused with ...

Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumour. To date, 60 well-documented cases have been published in the English-language literature. Two additional cases located in the posterior region of the mandible are reported. The relevant clinicopathological features of these cases, as well as those previously reported are discussed. Approximately two-thirds of AFS are malignant tumors de novo, with an average age of the affected patients being 22.9 years. This age is lower than the one observed in AFS developing from a pre-existent benign lesion (mean 33 years). Although regional and distant metastases are very infrequent, AFS is a locally aggressive lesion, with 23 (37%) of the reported cases having at least one recurrence; 12 patients (19.3%) died of the disease. Wide surgical excision with long-term follow-up remains the treatment of choice for this neoplasm ...

Trigliceridi, ki jih najdemo v oljih in maščobah so po definiciji estri glicerola z dolgimi verigami karboksilnih kislin. Hidroliza (umiljenje) ali transesterifikacija teh trigliceridov proizvaja stehiometrične količine glicerola. V tem procesu je glicerol proizveden kot so proizvodi pri dolgi verigi karboksilatnih soli, ki se uporabljajo kot milo. Glicerol je tudi stranski produkt proizvodnje biodizla prek transesterifikacije. Ta oblika surovega glicerina je pogosto temnega videza, z gosto, sirupu podobno konsistenco. Trigliceridi se obravnavajo z alkoholi, kot so etanol, s katalitsko osnovo za etil esterske maščobne kisline in glicerol. Glicerol iz trigliceridov proizvajajo v velikem obsegu, vendar je surovina spremenljive kakovosti, z nizko prodajno ceno (1-8 ameriških centov na funt v letu 2011). To je mogoče prečistiti, vendar je postopek drag. Rezultat tega je, da je velik del surovega glicerina odpadek. Glicerol se uporablja tudi kot energent, vendar je njegova toplotna vrednost ...
Če postopka (klasično križanje vs gensko modificiranje) zreduciraš na sestavne gradnike, torej na DNA, sta si postopka v bistvu podobna. Razlika je, da je klasično križanje podobno možganski operaciji, kjer kirurg uporablja sekiro, genetski inženiring pa je ista operacija z uporabo mikroskopa in ostalih modernih medicinskih inštrumentov. Pri klasičnem križanju uporabiš za starše primerke, ki imajo želene lastnosti in upaš, da bo določen delež potomcev izrazil lastnosti obeh staršev. To potem plemenitiš in križaš naprej, dokler nisi približno zadovoljen z rezultatom. Na molekulskem nivoju to pomeni rekombiniranje velikih področij DNA, pri čemer upaš na majhne spremembe in izločanje neželenih alelov. Kot rečeno, možganska operacija s sekiro.

Vedno sem verjel, da je psihoterapija koristna za druge, zase pa sem menil, da lahko kot empatičen in razmišljujoč posamenznik svoje težave rešujem sam. Nato sem se znašel v situaciji, ko v navidez popolnem življenju nisem več našel pravega smisla, počutil sem se nemočnega, ujetega v krog refleksij in dejanj, iz katerega nisem znal izstopiti. Od sebe sem pričakoval preveč, kar je vodilo v psihično in fizično izgorelost na skoraj vseh vitalnih življenjskih področjih. Zato sem se po sili razmer odločil, da poskusim s psihoterapijo.
