Giant lipoma of the thigh: A case report
A lipoma is a benign tumor which can occur in any part of the body; it is very frequent and can reach a considerable size. Differentiation between lipoma and liposarcoma of low grade malignancy represents an important diagnostic problem, and valuable help in the differential diagnosis is provided by ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), biopsy and/or modern immunohistochemistry. The authors report the case of a 50-year-old man who was referred to their department due to the presence of a large mass growing on the upper thigh of the right leg; over 7 years it had steadily increased in size causing pain and functional impotence. US of the soft tissues and CT scanning were performed. Densitometric values of the mass suggested adipose tissue, which was subsequently confirmed by biopsy.
