title: Differentiated adamantinoma: a case report and review of literature.
abstract: Adamantinoma of the long bones are uncommon, slow growing tumors with a predilection for the tibia. A special rare variant known as the osteofibrous dysplasia-like adamantinoma or differentiated adamantinoma is thought to be a precursor of the classic adamantinoma. We report a case in a 24 year old female who presented with pain and lytic lesion of the left tibia. Microscopy showed a tumor composed predominantly of osteofibrous dysplasia-like areas with focal cytokeratin positive epithelial islands. This case is highlighted because of its rarity, its association with good prognosis and possible misdiagnosis as osteofibrous dysplasia.
