Subserosal Sigmoid Lipoma: a Case Report and Review of the Literature.

Colonic lipoma is a rare non-epithelial mesenchymal tumour which is the second most common benign tumour of the colon excluding hyper-plastic polyps. It is often small and asymptomatic but may become symptomatic and mimic malignant lesions as the size increases. This is a case report of a 68 year-old female patient who presented with lower abdominal pain, constipation and rectal bleeding of one year duration. Colonoscopy revealed a sessile tumour 40 cm from the anal verge with an inconclusive histology. After incising and removing the lipoma, the redundant mucosal fold was then resected. The patient recovered completely and was discharged on the fifth postoperative day. Keyword: Colonic lipoma , subserosal lipomas.
