Abstract
Lipoma is a rare benign intraosseous neoplasm, constituted by adipose cells that can also arise on the surface of bone. It corresponds to less than 0.1 % of primary bone neoplasms, and 15 % of them are surface tumors. Main incidence is in the fifth decade of life. Most cases occur in the calcaneus and in the metaphysis of long bones. Surface tumors are seen over the diaphysis of long bones of the extremities. Lipomas are mostly asymptomatic. Radiographs show a lucent, well-defined intramedullary lesion, CT and MRI showing features similar to subcutaneous fat. Mineralized foci may be found inside the tumor. Non-evolutive tumors do not deserve treatment.
