Primary Pleural Extranodal Non-Hodgkin’s Lymphoma Presenting As Pleural Thickening—A Case Report

Primary pleural lymphoma is a rare entity that has been described in association with human immunodeficiency virus (HIV) infection or pyothorax. This paper reports on a 27 year old man with no history of HIV infection or pyothorax who presented with progressive dyspnea and heaviness of chest. Chest radiography revealed complete opacification of the left hemithorax, and contrast enhanced computed tomography showed large left pleural effusion and homogeneous, extensive thickening of the parietal pleura. CT guided biopsy of thickened pleura is suggestive of non-Hodgkin’s lymphoma-T cell lymphoblastic variety. Physicians should be aware of this rare location of primary pleural lymphoma manifested by thickening of the pleura.
