Solitary reticulum cell sarcoma of the uterine cervix with initial cytodiagnosis.

A minimally symptomatic elderly woman was discovered to have reticulum cell sarcoma involving the uterine cervix on the basis of cervico-vaginal smears taken in the absence of a visible mass lesion. The diagnosis was confirmed by biopsy, and subsequent clinical and operative staging revealed the tumor to be arising in and confined to the uterine cervix. The cytologic features of reticulum cell neoplasia are repetitive and highly characteristic irrespective of its site of origin.
