An Unusual Clinical Manifestation of Plasmablastic Lymphoma in a Renal Transplant Recipient.

Plasmablastic lymphoma is a rapidly progressive CD20 negative large cell non-Hodgkin lymphoma with poor outcome. It occurs mostly in immunocompromised individuals and has a predilection for extranodal sites. They need to be differentiated from other entities sharing similar morphological features like poorly differentiated carcinoma, Burkitt's lymphoma, Alk positive large B cell lymphoma, Diffuse large B cell lymphoma, and anaplastic myeloma. EBV negativity in recipients, type, intensity, and duration of immunosuppressives used are certain risk factors in development of posttransplant lymphoproliferative disorders. High index of suspicion can help clinch the diagnosis early and prevent catastrophic consequences. Our renal transplant recipient presented with complaints of pain abdomen and malena for which he underwent exploratory laparotomy. Diagnosis was established on histopathology and timely treatment initiated reverted the disease.
