Subperiosteal lipoma: A case report

Lipomas are the most common benign mesenchymal tumor. They can occur in various locations such as subcutaneous tissue, muscle, nerve, synovium, different periosteal layers, and bone [Diagnosis of bone and joint disorders. 3rd ed. Philadelphia: Saunders, 1995. p. 3814, 3947; Skeletal Radiol 27 (1998) 375]. To our knowledge, however, lipomas arising in a subperiosteal location have not been described previously. We present a patient with two subperiosteal lipomas of the femur.
