Intraosseous Lymphoma Presenting as a Fracture of the Femoral Neck

Abstract

Intraosseous lymphomas are uncommon bone malignancy, and most of them present with bone pain. Herein, we describe a case of 64-year-old male who suffered from a painful swelling over his hip after a motor vehicle accident initially, and radiography showed femoral neck fracture. He received bipolar hemiarthroplasty; however, the pathological examination of surgical specimen confirmed the diagnosis of diffuse large B cell lymphoma. This demonstration should remind physicians about the possible occurrence of bone lymphoma in the clinical setting of traumatic fracture in the elderly patients.

Primary intraosseous lymphoma at right femur

“…bone lymphoma which developed in the bone without involvement of any other site in the body. 3 Most of the intraosseous lymphomas should be metastatic, and primary intraosseous lymphoma is a rare type of lymphoma, which accounts for only about 5% extranodal lymphoma. It accounts for approximately 3% of all primary bone malignancies.…”
