Abstract

A giant intermuscular lipoma, an exceedingly rare occurrence, constitutes a non-malignant neoplasm originating from the mesodermal germ cell layer, with dimensions surpassing 10 cm. Its differentiation from liposarcoma and other malignant tumours is imperative. We present a case involving a 75-year-old woman who initially raised suspicions of liposarcoma due to pronounced enlargement and fullness in the upper quadrants of the left breast. After comprehensive imaging evaluations, the identification of a sizable BI-RADS 4a lesion positioned between the major and minor pectoral muscles of the left breast was found. The definitive diagnosis of an exceedingly rare giant intramuscular lipoma was validated solely subsequent to the surgical excision of the lipoma, through histological analysis.
