Diffuse cavernous hemangioma of the rectosigmoid colon with extraintestinal involvement.

Cavernous hemangioma of the colon is a rare cause of gastrointestinal bleeding. These lesions can be encountered as solitary, multiple, or part of a more complex syndrome with cutaneous manifestations. We herein describe a 26-year-old woman with cavernous hemangioma involving the rectosigmoid area. Additional hemangiomas were identified in the pelvic structures, spine, iliac bone and spleen. This multi-visceral involvement without cutaneous manifestations represents an intermediate variety between solitary hemangioma and well-defined syndromes with cutaneous and structural anomalies. The potential presence of extraintestinal hemangiomatosis should be considered and investigated in patients with cavernous hemangioma of the colon even without cutaneous manifestations or with a limited colonic involvement.
