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.
[Show abstract][Hide abstract] ABSTRACT: Confronted with a huge lipomatous anterior thigh tumor, the surgical approach had to be assessed. Those described in the literature did not seem appropriate for our case so some modifications were made. We present the case of a 77-year-old woman who presented with a huge anterior thigh compartment tumor with one-year evolution. Magnetic resonance imaging informed the presence of a lipomatous tumor with a possible vascular contact. Based on Thomson's anterior approach, but modifying the skin incision, the medial distal femur was reached until the neurovascular bundle and, proximally, the lesser trochanter. The tumor was totally resected due to a good visualization using this approach.
