Infiltrating Intramuscular Lipoma: A Rare Case Report

Abstract

Lipomas are the common benign tumors of adipose tissue, but sometimes clinically and grossly they simulate malignancy. Lipomas can also occur in deep soft tissues. One of its rare subtype is Intramuscular lipoma which arise within the skeletal muscle fibers. Most common site is trunk, but can also occur in thigh and head and neck. 20 % recur due to incomplete excision. Histopathology is must for confirmation of the diagnosis. Prognosis of intramuscular lipoma is very good and marginal excision is the treatment of choice. We report a case of a 23 Year old female, who presented in surgery OPD with chief complaint of swelling at upper right side of back since 1 year. She got operated for the same 8 months back but presented with similar complaint at same site after 4 months. Excision of the swelling was done and sent for histopathology. On gross examination skin covered soft tissue piece, grayish brown in color was received. Histopathology revealed Infiltrating intramuscular lipoma. The case was reported because of its rarity.
