Incidental Germinoma of the Basal Ganglia ― A Neuropathologic Study
Neuropathologic findings of a case of an incipient germinoma in the basal ganglia incidentally found in a twelve-year-old boy who died of an accidental head trauma are described. Germinoma cells, in groups or singly, infiltrated mainly into the anterior part of the lateral division of the globus pallidus, and also into the anterior limb of the internal capsule, putamen, nucleus basalis of Meynert, anterior commissure, and the head of the caudate nucleus of the left cerebral hemisphere. Fundamental cerebral structures were well preserved. Tumor cells were positively stained for placental alkaline phosphatase by the PAP method, and could easily be discriminated from remaining nerve cells.
