[Pleural effusion revealing non-Hodgkin lymphoma. Diagnose performed by videothoracoscopy].

We report the case of a 67-year-old man with an history of pneumopathy with pleural effusion and weight loss. Exsudative lymphocytic pleural effusion was found. Thoracoscopy gave diagnosis of widespread diffuse large B-cell NHL. Talc pleurodesis and CHOP-Rituximab regimen were performed with a favorable clinical and radiological response. We discuss about lymphocytic pleural effusion, especially associated with NHL and primary pleural lymphoma.
