Abstract

Hemangiomas are common benign tumors that usually occur on the head and neck in children. However, colonic hemangiomas are rare in clinical practice. Approximately 80% of colonic hemangiomas are of the cavernous type, and morphologically, ≥80% of colonic hemangiomas are sessile and semi-pedunculated. Notably, pedunculated colonic hemangiomas are rare. A 69-year-old woman presented with hematochezia and underwent colonoscopy, which revealed a soft pedunculated submucosal tumor (SMT) measuring 1.5 cm in diameter, in the sigmoid colon. The surface of the SMT resembled the surrounding normal colonic mucosa with regard to color and appearance, with multiple red patches. Narrow-band imaging revealed a few telangiectasias on the surface of the SMT. The lesion could not be definitively diagnosed based on endoscopic findings. Therefore, for more accurate diagnosis, the SMT was removed by snare polypectomy with electrocautery after clipping the basal portion of the tumor stalk for prophylactic hemostasis. Histopathological examination of the specimen revealed a cavernous hemangioma with a negative resection margin. We report a case of a pedunculated cavernous hemangioma of the sigmoid colon removed by snare polypectomy with electrocauter...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
