title: Mucinous urethral caruncle.
abstract: A case of urethral caruncle, composed exclusively of mucin-secreting colonic-type glands and believed to be the first on record, is described. The lesion presented clinically as an ordinary caruncle and was treated by local excision. The histogenesis of the lesion is discussed, and its probable origin from an intraurethral cloacogenic colonic gland rest is proposed.
