RESUMO
We report the case of a special form of rhabdomyosarcoma called "Iymphadenopathic" which was reported only two times in the literature. This lymphadenopathic alveolar RMS shows lymph nodes as clinical manifestation mimicking lymphoma with an unknown primary neoplasm. In the case we report, clinical examination, and radiological studies revealed superficial and deep located lymph nodes in association with bilateral pleural effusion. Conventional histological examination showed lymph node infiltration by a metastatic tumour having alveolar pattern. Some of tumour cells were round with multilobed off-centred nucleus and eosinophilic cytoplasm containing fibril material with longitudinal and transverse striation indicating a muscle nature of the tumour proliferation. The immunohistochemical study showed intense and diffuse immunoreactivity of tumour cells for vimentin and a discreet immunostaining by desmin. These findings were compatible with the diagnosis of lymph node metastasis by alveolar rhabdomyosarcoma
RESUMO
The endometrial stromal nodule is the rarest of the endometrial stromal tumours. It is a benign tumour composed of well- differentiated endometrial stromal cells arranged as a well-circumscribed nodule with smooth, non invasive margins. We describe a case of uterine stromal nodule occurring in a 45-year-old women with history of menometrorrhagia in which case ultrasonography conclude to a leiomyoma. Epidemiology, pathologic aspects, differential diagnosis, treatment and prognosis are reviewed
RESUMO
Multiple lymphomatous polyposis is a distinctive primary gastrointestinal lymphoma which endoscopical, histopathological et immunophenotypical characteristics are well known. This lymphoma is rare and its prognosis is bad because of frequency of stage IV patients. We report the case of a 75-yearold male patient with multiple lymphomatous polyposis affecting the rectum, the colon and the stomach associated with an involvement of lymphadenopathies, bone marrow and liver. Treatment by chemotherapy was ineffective and patient dead after 3 sessions of CEOP protocol
