title: Malignant gastric sarcoma--diagnosis by ultrasound and endoscopy.
abstract: A 14-year-old boy was presented with a mass in the epigastrium. The tumor developed 13 years after removal of a neuroblastoma of the left adrenal gland. Therapy of the primary tumor had included irradiation and chemotherapy. Diagnosis of the gastric tumor was made by ultrasound and endoscopy. A total gastrectomy was performed showing a malignant undifferentiated sarcoma. Primary malignant tumors of the stomach such as gastric teratoma of the newborn [4], leiomyosarcoma [6], malignant lymphoma and carcinoma [1] are very rare in childhood. As cancer is treated more aggressively with radiation and cytostatics, more therapy-induced-tumors, including gastric sarcoma, must be expected in children.
