Intramuscular Lipoma at Shoulder: A Rare Case Report.

ABSTRACT

Lipomas are the most common type of soft tissue tumors. Intramuscular lipoma is a rare type of deep-seated lipomas, which arise within the skeletal muscle fibres. It can arise in the background of history of trauma, obesity, chronic irritation, metabolic disorders, etc. Lipomas are usually benign, but sometimes clinically and grossly, they simulate malignancy. Intramuscular lipomas also need separation from muscular dystrophies. Histopathology is must to differentiate. Prognosis of intramuscular lipoma is very good and marginal excision is the treatment of choice. We report a case of 32 years old female, who presented with a painless swelling shoulder since six months. She had history of trauma eight years back. Grossly, the received mass was yellow-tan coloured, well circumscribed swelling of soft tissue along with muscle. Histopathologically, features are consistent with intramuscular lipoma. We report this case because of its rarity.
