Ruptured Giant Leiomyoma of the Appendix: A Case Report

Abstract

We present a case of a 79-year-old female who was admitted with acute abdominal pain and haemoperitoneum. Pathological findings demonstrated a spindled-cell lesion arising from the appendix. The lesion consisted of smooth muscle bundles arranged in fascicles with a whorled appearance. Appendicular leiomyoma is a rare lesion with only a few case reports previously described. We discuss the possible pathological differential diagnosis of such lesions, including GIST, leiomyosarcoma and schwannoma. We present a discussion of the utility of immunohistochemistry in such cases in order to diagnose such tumours.
