Abstract

Deep-seated lipomas can be intramuscular, intermuscular, and rarely, parosteal lipomas. Intramuscular lipoma can be divided into infiltrative, well-circumscribed, and mixed types. Marginal excision is the treatment of choice for well-circumscribed intramuscular lipoma, and histopathology eliminates diagnosis of well-differentiated liposarcoma. The purpose of this technical note is to describe the details of endoscopic en-bloc resection of intramuscular lipoma of the flexor digitorum profundus. This minimally invasive approach allows en-bloc resection of the lipoma for histopathological study, with minimal risk to the surrounding neurovascular structures.
