Niemann-Pick disease associated with nonimmune hydrops fetalis

The number of metabolic disorders associated with nonimmune hydrops fetalis is very small and includes only Gaucher disease, GM1 gangliosidosis type 1, Hurler syndrome, and mucolipidosis type I. We report another association of a nonimmune hydrops fetalis with Niemann-Pick disease as evident by electron microscopy, and wish to add this disorder to the list of conditions associated with nonimmune hydrops fetalis.
