Humphreys S., Lake B. D. & Scholtz C. L. (1985) Neuropathology and Applied Neurobiology 11, 475–484 Congenital amaurotic idiocy‐a pathological, histochemical biochemical and ultrastructural study A case of congenital amaurotic idiocy, a subgroup of the neurovisceral lipidoses, is described. This is a rare condition of which only five cases have been reported previously. The brain was small and firm with marked neuronal loss and gliosis. Granular material with histochemical properties of the ceroid‐lipofuscin group of lipopigments was found deposited within astrocytes, macrophages and residual brain stem neurons. Cells of the mononuclear phagocyte system within the liver, spleen, thymus and lungs contained similar material. Ultrastructurally this substance appeared as intracytoplasmic membranous and granular deposits within limiting membranes, and biochemical analysis of formalin‐fixed tissue did not identify a specific material. Comparison is made with the Batten group of disorders.
