title: Amyotrophic choreo-acanthocytosis: a neuropathological and immunocytochemical study.
abstract: A 47 year old man, one of a sibship affected by amyotrophic choreo-acanthocytosis was studied neuropathologically after some years of clinical observation. Besides the classic optical findings (neuronal loss, astrocytic gliosis and "status spongiosus" in the basal ganglia, namely in the caudate nucleus) a few MEnk+ and NPY+ neurons were observed immunocytochemically in the striatum. In the spinal cord also, while no neuronal loss was perceivable, both mild demyelination and interfibrillary astrocytic hyperplasia of the long tracts were present. On the other hand, microscopic findings of muscle and peripheral nerve showed no differences from what was previously intra-vitam appreciated in the same patient. The neuropathological and immunocytochemical findings of this case are discussed in relation to the differential diagnosis between amyotrophic choreo-acanthocytosis and Huntington's disease.
