[Primary pleural lymphoma: a rare complication of tuberculosis pleural sequelae]

We report two cases of malignant lymphoma of B phenotype occurring after therapeutic pneumothorax for tuberculosis. In both cases, outcome was fatal without time for specific treatment. Mainly reported in Japan, this pathology seems to be less frequent in western countries. As for B phenotype lymphoma associated with immunodeficiency, association with Epstein Barr virus is reported. Definite diagnosis is difficult and requires surgical biopsy. Prognosis remains poor with a survival ranging from 3 to 6 month.
