A 62-year old male presented with since more than 20 years lichen sclerosus of the preputium and glans penis. Recently new erosive lesions appeared. Histological examination showed squamous cel carcinoma; high risk HPV was not detected. The patient underwent a glansectomie. In contract to females, development of squamous cell carcinoma of the glans penis in genital lichen sclerosus in males is rarely seen. Carefull follow-up on a regular basis is therefore strongly recommended
