Unusual urethral diverticulum lined by colonic epithelium with Paneth cell metaplasia.
Diverticulum of the female urethra has an incidence of 1.4% to 4.7%. It is generally agreed that the majority of these are acquired lesions. There is, however, evidence that some are of congenital origin. Documented cases of diverticula with colon-type tissue are rare. A case of urethral diverticulum with colonic epithelium and features of Paneth cell metaplasia is presented. Causes, symptoms, diagnostic methods, and treatment are discussed.
