## Abstract

Colonic angiomyolipomas (CA) are very rare benign tumors arising from perivascular epithelioid cells. CA are most often found either during screening colonoscopies or as an incidental finding during abdominal imaging. However, some rare cases of CA are found to present with abdominal pain and hematochezia. In this article, we report a case of a 62-year-old man who presented with intermittent hematochezia and constipation who was found to have an angiomyolipoma in the sigmoid colon. The lesion was successfully removed endoscopically with no recurrence of bleeding and no complications within the first 30 days after the procedure.
