[A female patient with splenomegaly, interstitial pneumopathy and giant foam cells in bone marrow].
We describe a case of Niemann-Pick disease type B. A 13-year-old female adolescent of Turkish origin suffered from abdominal pain for several months, finally leading to hospitalisation. The investigations revealed splenomegaly and interstitial pneumopathy. The bone marrow contained giant foam cells typical of Niemann-Pick disease. Enzymatic analysis of a fibroblast culture confirmed the diagnosis of Niemann-Pick disease type B, with reduced activity of acid sphingomyelinase. Niemann-Pick disease is an inherited autosomal recessive lysosomal storage disorder of sphingolipids, resulting in an accumulation of sphingomyelin in the cells of the reticulo-histiocytic system due to an enzymatic defect. In Niemann-Pick disease type B the spleen and lung are the main organs affected. At present no treatment exists for this disorder.
