Plasmablastic Lymphoma in Epstein–Barr Virus-negative Patient

Abstract

Plasmablastic lymphoma is a rare and aggressive variant of diffuse large B-cell lymphoma. It often develops in immunocompromised patients, particularly in human immunodeficiency virus-positive individuals. This report highlights the development of such a rare, aggressive malignancy in an immunocompetent adult male with negative Epstein–Barr virus serology. The patient was diagnosed 6 months after the onset of neck and submandibular swelling. A pan-computed tomography scan revealed nodal and extranodal involvement of the iliac bone and iliacus muscle. Chemotherapy was planned, but the patient’s condition deteriorated and he died. This case helps us to understand the clinicopathological features of this malignancy in the Saudi population and may help in early detection and better prognosis.
