Abstract

The article provides a clinical case of urethral cancer in women. Primary urethral carcinomas are rare, less than 1% of all malignant tumors. According to the Rarecare Cancer Surveillance Agency for Europe (RARECARE), urethral cancer in women is 0.6 and 1.6 in men per 1 million people per year. A 56-year-old patient with histologically verified clear cell adenocarcinoma of the proximal urethra was monitored for 18 months. An aggressive course of the tumor process has been shown, which led to the need to perform anterior exenteration of the pelvic organs. The histogenesis of primary clear cell urethral adenocarcinoma has not been definitively determined. The atypical external localization in the described case suggests the periurethral origin of this cancerous tumor from the Skene’s glands. The demonstration of a rare form of urethral cancer, clear cell adenocarcinoma, contributes to the accumulation of knowledge about its histopathology and clinical course, as well as increasing cancer alertness in the treatment of urethral diseases in doctors of any specialty.
