Computed tomography demonstrated a marked circumferential left pleural thickening. A thoracoscopic pleural biopsy led to a diagnosis of high-grade B-cell lymphoma, not otherwise specified (HGBL, NOS). Lymphoma cells were positive for tumor necrosis factor (TNF) and interleukin-6. This is the first case report of TNF- and IL-6-producing aggressive HGBL, NOS in the pleura, in which radiological findings mimicked pleural mesothelioma. The aggressive tumor progression in the present case may have been caused by abnormal cytokine production from lymphoma cells.
