Osteoblastic metastasis of lymphoepithelioma simulating osteoid osteoma. A case history.
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.
