Balanitis Xerotica Obliterans
BXO (Genital Lichen Sclerosus)
Overview
Balanitis xerotica obliterans (BXO) is the term used for lichen sclerosus affecting the male genitalia, particularly the glans penis and foreskin. It presents as white, atrophic, sclerotic patches that can cause phimosis (inability to retract the foreskin), urethral stenosis, and functional impairment. It is an important condition to recognize and treat early to prevent complications including an increased risk of penile squamous cell carcinoma.
Key Symptoms
- White, porcelain-like, atrophic patches on the glans, foreskin, or urethral meatus
- Tightening and thickening of the foreskin (phimosis)
- Difficulty or pain with retraction of the foreskin
- Urethral narrowing causing weak or deflected urine stream
- Itching, soreness, or pain in the affected area
- Fissuring and cracking of the affected skin
Affected Areas
Glans penis, Foreskin, Urethral meatus, Penile shaft (less common)
Care Instructions
- See a dermatologist or urologist for evaluation and definitive diagnosis.
- Potent topical corticosteroids (such as clobetasol) are the first-line treatment.
- Regular emollients to keep the affected skin supple.
- Circumcision may be necessary for severe phimosis and is often curative for foreskin disease.
- Urethral dilation or surgery may be needed for meatal or urethral stenosis.
- Long-term follow-up is recommended due to the small but real risk of squamous cell carcinoma in affected areas.
