<unk>  arises from precursor lesions, which generally progress from low-grade to high-grade lesions. For HPV related<unk> s this sequence is as follows: # Squamous hyperplasia; # Low-grade<unk>  intraepithelial neoplasia (PIN); # High-grade PIN (carcinoma in situ—Bowen's disease, Erythroplasia of Queyrat and bowenoid papulosis (BP)); # Invasive carcinoma of the penis. However, in some cases non-dysplastic or mildly dysplastic lesions may progress directly into cancer. Examples include flat<unk>  lesions (FPL) and condylomata acuminata. In HPV negative cancers the most common precursor lesion is lichen sclerosus (LS).
