title: Carcinoma in situ in urethral diverticulum: pitfalls of marsupialization alone.
abstract: Carcinoma in situ was found in a urethral diverticulum in a fifty-one-year-old black woman. The discovery of this lesion lends support to the fact that biopsy of the urethral diverticulum should be performed even if a Spence-Duckett procedure is carrier out.
