Abstract

Introduction

Metastases to the urethra are a rare clinical entity. To our knowledge there are less than ten case reports described in the literature. In this report, however we describe a case of urethral metastases from a colonic cancer origin where the urethral lesion was the presenting symptom.

Case Report

A 69-year-old woman presented with a swelling at the urethral opening. Per vaginal examination revealed a hard tender lesion situated at the external urethral meatus with contact bleeding. Excision biopsy revealed adenocarcinoma. Immunohistochemical staining demonstrated that the tumour cells were strongly suggestive of a metastatic lesion from the colon. Subsequent investigations revealed that the patient did indeed have a sigmoid adenocarcinoma and underwent chemotherapy with a view to anterior resection and pelvic exenteration.

Discussion

Metastases to the urethra are rare. Treatment options have to be individualised to the extent of the disease and the symptoms of the patient. Immunohistochemical staining can help to a certain extent to point the direction towards the possible primary lesion. Atypical presentations of urethral lesions should be viewed with suspicion. A biopsy of the lesion is the only way of confirming diagnosis.
