Jejunoileal alveolar rhabdomyosarcoma. A case report.
Intestinal localization of rhabdomyosarcoma is exceptional, this case is the first to be published in the world literature. A 35-year-old patient with abdominal pain, fever, was found to have an infiltrative white-grey tumour, involving 20 cm the jejunoileal wall and also the surrounding mesenterium up to the origin of upper mesenterical vessels and lymph nodes. Histologic examination showed an alveolar type of rhabdomyosarcoma intricated with solid undifferentiated tumoral cells. The presence of multinucleated giant cells and the positivity of protein S 100 reaction was important for differential diagnosis, given the alveolar soft part sarcoma, malignant mesothelioma, malignant melanoma or papillary carcinoma.
