[Rapidly debilitating disease with generalized lymphadenopathy, skin involvement and interstitial pulmonary infiltration (report of three cases)].

Generalized but well-circumscribed lymphadenopathy and rash-like skin changes were observed in three men, aged 58 to 75 years. There was a reticular appearance in the chest X-ray. Dyspnoea, weakness, marked weight loss, changing but marked lymphopenia, markedly increased blood-sedimentation rate, and an always negative Tine test were present in all three. Despite antibiotics, cytostatic drugs and prednisolone the disease quickly ended fatally with high fever, general debilitation and pneumonia. Post-mortem examination revealed diffuse lymphatic hyperplasia with plasma-cell infiltration in the lymph nodes, tonsils and lymphatic tissue of the intestines, and diffuse hyperplasia of the endothelial venules, together with basophilic blast cells, eosimophilic granulocytes and reticulum cells with broad nucleoli. The spleen was normal or enlarged. Spleen, lung tissue and lymphatics, the skin in the area of the small vessels, hair follicles and sweat glands contained lymphocytes, plasma cells and eosinophilic leucocytes. The spleen, if enlarged, also had focal necroses in its periarteriolar septa. In two cases electrophoresis revealed beta-globulin poorly demarkated from gamma-globulin, doubling and increase. In the third case, IgA was markedly increased with one each monoclonal IgG1 und IgA, and corresponding shift in the chi/lambda relationship in serum. Immunohistologically, lymphocytes were made up of about 20 percent IgG-containing and about 25 percent IgA-containing cells. Lymphopenia, if present, was associated with markedly reduced blast transformation of peripheral lymphocytes to phytohaemagglutinin. The granulocytes were defective (intracellular killing of Candida albicans and Staphylococcus aureus), while the nitrobluetetrazolium test was normal. There was RBC phagocytosis in the macrophages of bone marrow and in Kupffer cells of all three cases.
