Does lichen sclerosus occur on other body parts?
Lichen sclerosus most often affects the vulva, penis, and perianal area, but can rarely occur on other parts of the body such as the upper trunk, breasts, or inner thighs (extragenital lichen sclerosus).
Detailed Medical Explanation
Extragenital lichen sclerosus presents as white, slightly indented or wrinkled patches anywhere on the skin, though this is much less common. These lesions are usually asymptomatic, but may cause mild itching or discomfort. Unlike genital involvement, extragenital lesions do not increase cancer risk. For more details, see NHS and BAD.
Clinical Context
If you notice persistent white patches on non-genital skin, see a dermatologist for assessment. Our clinic can offer advice or referral: Vulval Skin Conditions Clinic.
Evidence-Based Approaches
Extragenital lichen sclerosus is rare. Diagnosis is confirmed by clinical exam or biopsy. For guidelines see NICE BNF.
