title: Osteoblastic metastasis of lymphoepithelioma simulating osteoid osteoma. A case history.
abstract: An unusual case of solitary osteoblastic bony metastasis at the proximal end of the femur from lymphoepithelioma is presented. Except for the age of the patient, the clinical picture bore a striking resemblance to that of an osteoid osteoma. The patient's belated report of a history of nasopharyngeal carcinoma gave the clue to an accurate diagnosis.
