We report postmortem findings in a 46-year-old man with dominantly inherited parkinsonism whose symptoms started at age 28. At least 13 other family members in three generations have been affected, some from early childhood. Dystonia is a prominent feature in several of the youngest patients, but was not present in this patient. After several years of successful treatment with medication, he developed severe on-off fluctuations and dyskinesias. At age 45, the patient underwent stereotaxic implantation of autologous adrenal medullary tissue into the left corpus striatum and lateral ventricle. He improved considerably over the following 6 months, but then developed glioblastoma multiforme and died 1 year after transplantation. There was severe neuronal loss in the pars compacta and pars reticulata of the substantia nigra, with prominent gliosis in the pars reticulata. The nigral neurons remaining in the pars compacta were poorly pigmented. Neither Lewy bodies nor neurofibrillary tangles were present, and we identified no other degenerative neuropathologic changes. This combination of pathologic and clinical features differs from any previously reported case.
