Epitheloides Leiomyosarkom des Magens mit hämorrhagischem Aszites

: In two men (69 and 65 years old) a gastric epithelioid leiomyosarcoma more than 25 cm in diameter first manifested itself by an increase in abdominal girth and ascites. In case 1, a cylindrical mass was palpable in the abdomen increasing in size over two years. Sonography and computed tomography showed a large cystic tumour which could not be related to any one organ. Cytology of the ascites fluid did not reveal any tumour cells. At operation a pedunculated tumour, 29 x 20 x 9 cm, was found, originating from the stomach. Six litres of ascites fluid were aspirated. There were no detectable abdominal metastases. The patient died nearly 4 years later after the tumour had been resected, three further laparotomies had to be performed because of extensive metastases to peritoneum and liver from the leiomyosarcoma. In case 2, no abdominal mass was palpable, but the patient's girth had increased over the last year. Sonography revealed a cystic tumour, about 30 cm in diameter. Examination of haemorrhagic ascites fluid (700 ml) did not show any tumour cells. The tumour, originating from the stomach wall, was excised (no metastases were seen). The patient remains symptom-free after 35 months.
