Case report 730. Malignant large cell lymphoma of tibial epiphysis.

Abstract

We present a case of primary lymphoma of bone arising in the proximal tibial epiphysis of a 16-year-old boy. To the best of our knowledge, primary lymphoma of bone has not been described previously as a mimicker of chondroblastoma. This case report is intended to increase awareness among clinicians and radiologists that primary lymphoma of bone can present with a long clinical prodrome and initially benign radiographic appearance. Early recognition of this unusual presentation will (hopefully) increase the likelihood of cure. However, it is recognized that in children, primary lymphoma of bone is a rare diagnosis and associated with a poor prognosis unless aggressive treatment is utilized [8].
