Abstract

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