Osteochondrolipoma is an extremely rare histological variant of lipoma with most reported cases in the head and neck area and the upper half of the body. We report a case of osteochondrolipoma occurring in the right distal fibula of an 11-year-old female. The physical examination revealed a painless, firm swelling over the right ankle joint with no history of trauma preceding it. Histologically, the tumour showed the presence of sheets of mature adipose tissue admixed with mature bony trabeculae. Also, seen in between were the foci of cartilage, proliferating fibroblasts, numerous blood vessels with the evidence of endochondral ossification favouring the diagnosis of osteochondrolipoma. Considering its rare site, the clinicians and pathologists should regard osteochondrolipoma as a possible diagnosis for a well-defined, calcified/ossified mass in the lower half of the body.
