Endoscopic En Bloc Resection of Intermetatarsal Lipoma

A lipoma, which is composed of fatty tissue, is the most common benign soft-tissue tumor. Lipomata can develop anywhere in the body including the intermetatarsal space. The intermetatarsal space is filled by dorsal and plantar interossei muscles, and a lipoma in this space will extend outside this space as the tumor grows. Classically, lipoma is resected via an open approach, which may result in a lengthy disfiguring surgical scar. The purpose of this Technical Note is to describe the details of endoscopic en bloc resection of intermetatarsal lipoma. This minimally invasive approach can provide a whole block specimen for histologic examination and reduce tumor seeding as compared with endoscopic piecemeal resection of lipoma.
