RT Journal Article T1 Giant pleomorphic lipoma in patient with multiple osteochondromatosis A1 Thorpe Plaza, Benjamín Alfonso A1 Lage, Paloma A1 Beiras, Carolina A1 Bargas-Osorio, Kelly A1 Canseco, Francisco K1 Pleomorphic lipoma K1 Giant lipoma K1 Lipoblasts AB Pleomorphic lipomas are infrequent soft tissue tumours with pseudosarcomatous behaviour. Their polymorphism provides them certain characteristics that may resemble malignancy, which may mislead the initial diagnosis. The presented case report is a 45-year-old man with a giant growing tumour on the left cervicoscapular region initially categorised as a liposarcoma by magnetic resonance with a final confirmed diagnosis of pleomorphic lipoma after the surgical resection and the examination of the pathologist. The patient presented important functional restriction of the upper left extremity, which decreased after surgical resection, improving the quality of life.
