[Primary mucinous carcinoma of the female ureter]

The authors report a new case of primary mucinous carcinoma of the urethral meatus in a 66-year-old patient, treated by simple excision. The patient is in very good general health one year after the diagnosis. Although primary mucinous carcinoma of the female urethra is very rare, this diagnosis should be considered in any case of macroscopically suspicious urethral polyp, after having eliminated a gastrointestinal, vesical or gynaecological origin. Only seventeen cases have been published in the literature. Unlike our case, most of the reported lesions involved all of the urethra at the time of diagnosis and frequently presented extension to periurethral tissues or adjacent organs. A very poor prognosis is reported in the literature, even despite treatment, based on surgery and/or radiotherapy.
