Radiologically and Histologically Mixed Liposarcoma: a Report of Two Biphasic Cases
Departments of 1 Orthopaedic Surgery and 2 Pathology, Tohoku University School of Medicine, Sendai, and 3 Department of Radiology, Iwate Medical University, Morioka, Japan
We report two cases of liposarcomas showing biphasic patterns, radiologically and histologically. The first case was a 52-year-old man with a 17 x 12 cm intramuscular tumor in the right thigh. MR imaging revealed a mass composed of two components: a fat component and another soft tissue component. Histological diagnosis revealed mixed-type liposarcoma consisting of well-differentiated and myxoid liposarcoma. The second case was a 62-year-old man with a 22 x 15 cm intramuscular tumor in the left calf. MR imaging showed a mass composed of fat and non-fat components. The histological diagnosis was well-differentiated and pleomorphic liposarcoma.
