Summary
Definition
Genital warts are the most prevalent form of viral genital mucosal lesions and are caused by infection with several types of human papillomavirus (HPV).[1] The infection manifests as verrucous fleshy papules that may coalesce into plaques. Lesion size ranges from a few millimetres to several centimetres.[2] The warts may be located anywhere in the anogenital or genital area, including on mucosal surfaces.[3] The colour can vary from whitish to flesh-coloured to hyperpigmented to erythematous.

Lesions typically appear within weeks to months after exposure to HPV.[4] They are generally asymptomatic, but may be painful, friable, or pruritic.[5][6] This monograph will cover diagnosis and treatment of internal and external warts, excluding cervical warts.
