A case report of a huge congenital granular cell epulis operated under local anesthesia

Congenital granular cell epulis (CGCE) is a very rare benign soft tissue lesion of the neonate, it most frequently located on the anterior maxillary alveolar ridge. It has a female predilection. It is a tumor with no tendency to recur after excision. The exact histogenesis of this tumor remains unresolved and it may be hamartomata.Key words: Congenital granular cell tumor, gingival tumor, newborn, local anesthesi

A rare neuronal tumor of the cerebellum with myoid features

We report an extremely rare tumor presenting with myoid features in the left cerebellar hemisphere in a 62-year-old man. This tumor consisted of medium to large round cells with focal lipomatous and myoid differentiation. Immunohistochemically, the tumor cells expressed synaptophysin, GFAP (glial fibrillary acidic protein) and focally desmin. From these findings, we concluded that this tumor was a liponeurocytoma with myoid features. To the best of our knowledge, this report constitutes the second described case of liponeurocytoma with myoid differentiation in the cerebellum

Adénocarcinome vaginal primitif de type intestinal: cas clinique et revue de la littérature

L'adénocarcinome vaginal de type intestinal est une tumeur rare. Il pose un problème d'étiopathogénie, de diagnostic différentiel (avec un ADK rectal ou métastatique) et de prise en charge thérapeutique. Nous rapportons le cas d'une patiente de 46 ans, qui présente depuis 8mois des leucorrhées brunâtres. L'examen clinique trouve la présence d'une lésion infiltrante de 4cm, au dépend de la paroi postérieure du vagin avec envahissement de la cloison recto-vaginale. La biopsie a révélé un adénocarcinome colloïde muqueux de type intestinal. Cette interprétation histologique orientait vers une métastase vaginale d'un ADK gastro-intestinal, cependant, l'examen clinique, la recto-coloscopie, le scanner abdominal et l'imagerie par résonance magnétique (IRM) pelvienne ont permis d'exclure cette possibilité. La patiente a reçu une radiochimiothérapie concomitante (RCC), suivie d'une résection chirurgicale. L'examen anatomopathologique de la pièce opératoire a montré une stérilisation totale de la tumeur. Après 2 ans de suivi la patiente a développée des métastases osseuses multiples témoignant de  l'agressivité de cette tumeur.Key words: Adénocarcinome vaginal, type intestinal, radio-chimiothérapie, chirurgie, mauvais pronosti

Epithelioid sarcoma: a clinicopathologic and immunohistochemical analysis of 106 cases from the French sarcoma group.

Epithelioid sarcoma (ES) is rare with a poor prognosis and for which a loss of INI1 expression has been recently reported. We report a study of 106 cases with clinical, histologic, and immunohistochemical data, including INI1 expression, and follow-up data. Of the 106 cases, 70 were the conventional subtype and 36 the large cell subtype. INI1 was negative in 86 cases (81.1%): 57 (81%) of 70 conventional and 29 (81%) of 36 large cell subtypes. Treatment modalities were available for 76 and follow-up for 80 patients. Of the 80 patients, 43 (54%) experienced metastasis and 25 (31%) died of the disease. Univariate analysis indicated that tumor size and mitotic index were significant for metastasis-free survival, whereas proximal location, tumor size, tumor multifocality, and mitotic index were significant for overall survival. Loss of expression of INI1 is frequent in the conventional and large cell subtypes of ES and can be used as a diagnostic marker, but it has no prognostic impact
