[Plasma cell granuloma of the lung and mediastinum in a ten year old girl].

A ten-year-old girl presented with an asymptomatic tumor of the lung. X-ray morphology suggested malignancy. Laboratory investigations revealed hypochromic anaemia, strong signs of inflammation, and hypergammaglobulinaemia. By means of surgery the tumor was completely removed. Histologic analysis established the diagnosis of a plasma cell granuloma. Postoperatively, laboratory parameters normalized. During the follow-up period of now 30 months there has been no relapse.
