Underwater Mucosectomy to Treat Colon Mesenchymal Leiomyoma Lesion - a Rare Case Report

Abstract

Abstract Introduction: Leiomyomas are rare on the colon and represent only 3% of cases. They are frequently asymptomatic and are often found accidentally during colonoscopic examination. Colonic leiomyomas have an excellent prognosis and do not tend to recur after removal.Case: We report a rare case of submucosal leiomyoma, in the colon, diagnosed during a routine colonoscopy and resected by underwater mucosectomy.Conclusion: Although rare, colonic leiomyomas are a differential diagnosis for pre-cancerous epithelial lesions and should be considered when a polyp is found. In this case report we present what is likely the first case to be successfully resected through underwater mucosectomy.
