Abstract
It is very rare to encounter the malignancy of the small bowel. Especially leiomyosarcoma is characteristic of both an exoenteric growth and a cavernous formation in the tumor. And that, occasionally fistura may be formed between the cavity in the tumor and the mucosal ulceration. Through this fistura an abscess would be formed in the cavity.
A rare case of leiomyosarcoma is reported, who was complicated by abscess formation in the cavity which brought about septic shock.
