What is penile lichen sclerosus in men?
Penile lichen sclerosus, also called balanitis xerotica obliterans (BXO), is a chronic skin disorder that affects the foreskin and glans penis in men. It causes white patches, tightness, pain, and sometimes difficulty urinating.
Detailed Medical Explanation
This condition causes the skin to become pale, shiny, and tight, potentially leading to phimosis (inability to retract the foreskin), splitting, or narrowing of the urethra. It is not sexually transmitted or due to poor hygiene. Treatments include potent topical steroids or circumcision if severe. Regular monitoring is needed because of a small increased risk of penile cancer. More at NHS and BAD.
Clinical Context
Penile lichen sclerosus should be managed by a dermatologist or urologist. Our clinic offers partner education and referral pathways: Vulval Skin Conditions Clinic.
Evidence-Based Approaches
Topical steroids are first-line. Circumcision may be advised for phimosis or severe cases. Regular check-ups are essential. See NICE BNF.
