title: Primary sternum diffuse large B-cell lymphoma: A case report and review of the literature.
abstract: Primary bone lymphoma (PBL) is a rare disease, accounting for >1% of all cases of malignant lymphoma. Diffuse large B-cell lymphoma (DLBCL) is the most common histological type of PBL. The present study reported the case of a 68-year-old male with primary bone DLBCL, originally occurred in the sternum, which is a rare form of presentation. Computed tomography (CT), magnetic resonance imaging and bone emission CT were performed, followed by immunohistochemical analysis of a biopsy specimen, and the results were used to establish the diagnosis. At the time of diagnosis, no osseous involvement was observed. The clinical, radiological and histological features of PBL can mimic other medical conditions, thereby making the diagnosis difficult, and frequently leading to delays in treatment. The present study investigated the clinical features, management and prognosis of PBL, and reviewed previous relevant cases.
