Hodgkin's disease with a granulomatous pulmonary presentation mimicking sarcoidosis.

A prominent sarcoid like pulmonary granulomatous reaction to Hodgkin's disease was diagnosed six months before extrapulmonary Hodgkin's disease was confirmed histologically. It recurred with exacerbations of the lymphoma. The reaction is similar to that often seen at pathological staging of intra-abdominal organs not affected by Hodgkin's disease.
