testicular cancer is one of the commonest cancers in men of working age, and is increasing in incidence in europe and north america. one suggested mechanism of causation is that there is impaired differentiation of germ cells in the pre- or perinatal period, followed by malignant transformation in later life, possibly by a hormonal mechanism. endocrine disrupting chemicals (edcs) have been a ma...

In general, prevalence chronic approximated 5% in each populations, but there are obstacles diagnosing diarrhea, due many differential diagnoses diarrhea.

Central giant cell granuloma is a benign, aggressive neoplasm composed of multinucleated giant cells that almost exclusively occurs in the jaws though extra-gnathic incidence is rare.Multifocal CGCGs of the jaws are very rare and suggestive of systemic diseases such as hyperparathyroidism,an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome or other disorders.Very few c...

Plasmablastic lymphoma (PBL), a very aggressive variant of diffuse large B cell lymphoma (DLBCL), has been described initially as a rapidly progressive and almost invariably fatal diffuse large-cell lymphoma with plasmablastic features. Immunohistochemical findings showed generally CD20 antigen negative and VS38c, CD138 and MUM 1 positives. This neoplasm was initially described almost exclusive...

Clear cells can be found in numerous salivary and non-salivary tumors in the head and neck region, including metastatic lesions. They are rare low-grade tumors accounting for less than 1% of all salivary gland tumors and occur almost exclusively in the intra-oral minor salivary glands. Hyalinizing clear cell carcinoma (HCCC) is an extremely rare and recently described neoplasm predominantly aff...

The epithelioid hemangioendothelioma (EH) is an uncommon angiocentric neoplasm of borderline or intermediate malignant potential, between the hemangioma and conventional angiosarcoma. It is characterized by the proliferation of endothelial cells with epithelioid or histiocitóide morphology with vacuolated cytoplasm and occasional eosinophilic spindle cells. Shows potential for local recurrence ...

Oral mucosal melanoma (OMM) is an aggressive neoplasm with an extremely poor prognosis. BAP1 is a tumor suppressor that has been associated with the outcome of melanomas and other malignancies. In this study, we investigated the genetic alterations in BAP1 and the prognostic potential of BAP1 protein expression in oral mucosal melanoma. DNA sequence analysis of BAP1 from 12 OMM patient samples ...
