title: Perforated leiomyosarcoma of Meckel's diverticulum.
abstract: A case is reported of perforated leiomyosarcoma of Meckel's diverticulum. The patient presented with localized peritonitis which responded to antibiotic therapy, and diagnosis was not made until elective resection of a tubulovillous adenoma of the rectum which was found in the course of investigation. Although rare, leiomyosarcoma is the commonest malignant tumour of Meckel's diverticulum.
