[Rare abdominal manifestations of tuberculosis: isolated splenic tuberculosis and peritoneal tuberculosis].

Two patients with rare localizations of extrapulmonary tuberculosis are presented. In a 55-year-old man admitted with septic fever and a low neutrophil count, ultrasonography of the spleen revealed splenomegaly with numerous hypodense foci. Fine needle biopsy of one of the foci disclosed tuberculosis.

[Diagnosis and therapy of pneumocystis carinii pneumonia in a patient with AIDS].

The clinical, immunological and histological findings in a patient suffering the acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia are discussed. At the time of diagnosis HTLV III antibodies were not demonstrable. Treatment with trimethoprim sulfamethoxazole achieved a remission lasting 7 months so far.

[Non-secreting myeloma. Case report with immunohistologic and electron microscopic studies].

Immunological, immunofluorescence and electromicroscopic studies were performed in a case of atypical myeloma. The 77-year-old patient presented with skeletal pain, multiple osteolytic lesions and bone marrow infiltration by atypical plasma cells. Monoclonal light chains kappa were confined to the plasma cells, as shown by immunofluorescence.

[Wegener's granulomatosis as a rare cause for kidney failure].

Course and treatment of a case of Wegener's granulomatosis are reported. A 39-year-old man admitted to the hospital because of abnormal densities demonstrated by the X-ray examination of the chest. The patient developed a rapidly progressive renal failure with renal insufficiency.

Symptoms and immunology of the Henoch-Schönlein-syndrome.

The Henoch-Schönlein-syndrome, or anaphylactoid purpura, is usually a childhood disease. The progess of this syndrome in adults was observed in 4 cases at our clinic. An elevated IgA level in the serum with a normal complement value seems to be of immunological interest.
