Abstract
|
|
|
Ewing¡¯s sarcoma is a neoplasm of the undifferenciated small round cells, which generally affects the bone and deep soft tissues of children and adolescents. We present a case of gastric Ewing¡¯s sarcoma; a 35-year-old female who had no symptoms. While she was at a routine medical checkup, a protruding mass in her gastric antrum was incidentally found on esophagogastroduodenoscopy. Endoscopic ultrasonogram showed a submucosal mass on the same lesion and a laparosopic wedge resection was done. Pathologic gross findings showed a granular grape appearance tissue and histoloigc examination revealed a small round cell tumor with CD 99 immunoexpression positive. In general, a combined modality therapy for Ewing¡¯s sarcoma such as surgical resection with chemotherapy, is accepted as an effective method. However, this patient had no adjuvant chemotherapy after surgery and she has no recurrence for eleven months.
