An autopsy case of Menkes kinky hair disease

An autopsy cases of Menkes kinky hair disease in a 1 year and 8 months old male infant is presented and compared with the morphological findings of the previous literatures. The main pathological changes are atrophy of the whole cerebellar cortex and bilateral temporal lobe, atrophy with demyelination of the white matter, tortuous running of the cerebral arteries, multiple diverticulosis of the urinary bladder and hyaline-like deposition in the gastric submucosa. Microscopically, the peculiar degenerative change of Purkinje cell (somal sprout) is the only characteristic lesion in our case and the others. It is suggested that Menkes kinky hair disease may be a syndrome due to metabolic disturbance appearing not only in ectoderm such as the central nervous system, but also in mesoderm such as connective tissue and bone.
