title: [Current diagnosis and treatment of male genital lichen sclerosus].
abstract: Male genital lichen sclerosus (MGLSc) is a chronically relapsing disease characterized by a long course, gradual aggravation, and a tendency towards malignancy. Once called balanitis xerotica obliterans, MGLSc has a distinct predilection for the prepuce and glans, involving the urethra when aggravating, forming scarring tissues, and causing urethral stricture, which may seriously affect the patients'quality of life with such symptoms as urinary stream narrowing, dysuria, and painful penile erection. The etiology and pathogenesis of MGLSc have not yet been adequately explained though it is generally thought to be associated with autoimmune mechanism, genetic factors, infections, local trauma, and chronic urinary irritation. MGLSc can be fairly easily diagnosed according to its clinical manifestations and histopathological results, but can be hardly cured. Early diagnosis and prompt treatment are the most important approaches, which may relieve its symptoms, check its progression, and prevent its long-term sequelae. Ultrapotent topical corticosteroids are the choice for the treatment of MGLSc. For those who fail to respond to expectant medication or have dysuria due to urethral stricture and painful erection, rational surgery may be resorted to, with importance attached to long-term follow-up. This article presents an update of the diagnosis and treatment of MGLSc and MGLSc-induced urethral stricture.
