[Primary reticulosarcoma of the central nervous system (author's transl)].

Among the last 7000 consecutive autopsies from our department, nine cases of primary reticulum cell sarcoma (non hodgkinian malignant lymphoma) of the central nervous system were discovered. Another case was found by cerebral biopsy. There were six males and four females (mean age 43.5 years). Mean duration of illness to time of death was 4.6 months. Gross examination revealed a wide range of neuropathological lesions (multifocal or diffusely infiltrating the parenchyma) and predominant in the cerebral hemispheres. Review of this materal underlines the difficulty of clinical diagnosis and the need to search for a more specific tratement.
