Sigmoid Colon Angiomyolipoma as a Culprit for Intermittent Constipation and Hematochezia.

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.
