Pleomorphic Leiomyosarcoma of the Jejunoileal Mesentery: A Histopathological Case Report.

Gastrointestinal leiomyosarcomas are rare malignancies. Herein, we present a case report of a previously healthy 60-year-old female presenting with periumbilical abdominal pain, vomiting, and difficulty in passing stool, with clinical workup, imaging, and surgery defining a small intestine tumor. Histology defined the tumor as a mesenteric pleomorphic leiomyosarcoma.
