Angiosarcoma in the small intestine. Apropos of a particular case.

Presentation of a case of small intestine primary angiosarcoma in a 70-year-old male. There is question of an extremely rare tumor in the gastrointestinal tract. Its symptomatology is similar to that of other tumors in the small intestine. An immunohistochemical study is usually essential for its anatomopathological diagnosis. The diagnosis is generally arrived at in its advanced stages, and that makes for a bad prognosis. The bibliography has been revised from this case on.

Granular cell tumors (GCT) are rare and usually benign tumors whose histogenesis is debated. The skin, subcutaneous tissues, and mucosae of the head and neck are areas of predilection for GCT. Laryngeal involvement is uncommon, but may create diagnostic and therapeutic problems when it occurs. Laryngeal GCT are decidedly uncommon in children, only 17 cases having been reported in the literature. A case of GCT of the larynx in an 11-year-old girl is reported. The presenting symptom was hoarseness. The macroscopic tumor and hoarseness disappeared after chemotherapy (EVAIA) for Ewing sarcoma of the knee.
