A 62-year-old female patient had occasional bleeding from a massin the urethral meatus. She had been conservatively treated withsteroid ointment at another hospital for 1 year, but the bleedinghad persisted. The patient was therefore referred for further treatment.A reddish mass, measuring 5 mm in diameter was noted atthe posterior lip of the urethral meatus. The mass was diagnosedto be a urethral caruncle and was removed. Microscopically, thesquamous epithelium, which covered the urethral caruncle, wasfound to be keratinized, with the proliferation of atypical cells withswollen nuclei in the entire mucosal layer. The mass was finallydiagnosed to be intraepithelial squamous cell carcinoma arisingfrom the urethral caruncle.The occurrence of intraepithelial squamous cell carcinomaarising from a urethral caruncle is extremely rare. A search of theEnglish literature revealed only 1 other case report.
