Multiple sulfatase deficiency: bridge between neuronal storage diseases and leukodystrophies.
A fatal case of multiple sulfatase deficiency in a 10-year-old girl is reported. In this rare disease, which is inherited as an autosomal recessive, features of metachromatic leukodystrophy and of mucopolysaccharidoses occur together. The white matter suffers progressive destruction with sulfatides accumulating in macrophages; these stain metachromatically as golden brown granules with acetic acid thionin stain. Cortical and subcortical neurons are distended by lipids and mucopolysaccharides, and fibrous thickening of the leptomeninges leads to severe obstructive hydrocephalus. This entity can be regarded as a bridge between leukodystrophies and neuronal storage diseases both conceptually and in its morphological manifestations.
