One variety of sarcoma of the central nervous system (CNS) has been referred to under such synonyms as perithelial sarcoma, microglioma, and reticulum cell sarcoma. A case of diffuse involvement of the CNS is reported and the author believes that the tumour is a reticulum cell sarcoma because: (1) in addition to involvement of the CNS, lesions characteristic of a diffuse lymphomatous process were present in extraneural sites; (2) silver carbonate impregnation of the tumour cells was demonstrated. This tinctorial property has been reported as characteristic of microgliomas but has been shown to be an unreliable criterion for the differentiation of the cells of microglial from those of reticulum cell sarcomas. It is concluded that in such cases the CNS is the initial and major focus of a multicentric malignant lymphoma which has the histologic characteristics of a reticulum cell sarcoma.
