[Plasma cell granuloma of the lung. Report of two cases (author's transl)].

The authors report two cases of inflammatory pseudotumour of the lung, one discovered by chance in a 15 year old boy and the other following a hemoptysis in a 48 year old man. In both cases, the granuloma was mainly fibroblastic but also included lymphocytes and plasma cells, macrophages and mast cells. The histology, age of onset, the sex and the pulmonary localisations are different for plasma cell granulomas and fibrosing hemangiomas.
