Abstract
Leiomyosarcoma limited to the small intestine is extremely rare. Our case is unique in that it presented with an abdominal abscess due to leiomyosarcoma of the small intestine.
A 58-year-old man was hospitalized with the chief complaint of an abdominal tumor. Roentgenography after ingestion of barium showed the dislocation of the small intestine and the colon due to tumor with air-fluid level. At surgery, an abdominal abscess was found in the lower abdominal region and a drainage was performed. Three months later, the patient underwent second laparotomy. There was a large tumor mass, 15×15.5×5cm in size, arising from jejunum. Resection of the tumor was done. Central necrosis, having no connection with jejunum, was found inside the resected-tumor. Microscopic sections revealed leiomyosarcoma.
When seen at the end of two years, the patient was asymptomatic.
