Successful Radical Endoscopic Resection of a Rare “Octopus Head Like” Symptomatic Giant Lipoma of the Sigmoid Colon

A Nigerian 29-year-old-female was admitted for hematochezia and obstructive symptoms. CT-scan showed a sigmoid intussusception with huge hypodense mass of adipose density.Colonoscopy/EUS confirmed a semi-peduncolated ulcerated submucosal mass (third layer). The lesion was resected “en-bloc” with large diathermic snare, using high-voltage mixed Endocut to overcome the poor electrical conductivity of fat. A small solution in the cutting edge was closed positioning endoclips.Macroscopically, the piece appeared as a smooth lesion, 7x4cm, resembling the head of an octopus. Histology showed radical resection of giant lipoma with characteristic fatty cells S-100 protein positive in the submucosal layer. Clinical course was regular.
