Overview

Balanitis xerotica obliterans (BXO) is a dermatological (skin) condition affecting the male genitalia. It was first described by Stuhmer in 1928, though earlier reports describe what may have been the same condition.[1] BXO commonly occurs on the foreskin and glans penis.[2] Atrophic white patches appear on the affected area,[3] and commonly, a whitish ring of indurated (hardened) tissue usually forms near the tip that may prevent retraction.[2]
