[Pneumocystis carinii pneumonia in a HIV-positive patient]

The authors publish a case report of a young man, who have got a severe pneumonia, which did not recover after antibiotics treatment. When the cause of the immunosuppression was investigated, HIV positivity was found, and Pneumocystis carinii was recognised in the bronchoalveolar lavage fluid. The diagnosis of the lung complications and the possibilities of the treatment are discussed.
