If men suffer from warts, they can be diagnosed by visual observation, dermatoscopy, and tissue biopsy, as follows: 1. Visual observation: doctors generally identify warts after careful and close observation of the patient’s genital and anal areas. If there are warts visible to the naked eye, the diagnosis can usually be confirmed without additional testing. 2, dermoscopy: For some tiny warts, dermoscopy can now be used to help diagnose them. 3, tissue biopsy: If the lesions of warts are atypical, such as when they show hyperpigmentation, sclerosis, rapid growth, bleeding, ulcers, or when the doctor deems it necessary, a biopsy can be performed. The histopathological examination of the lesions can help in the diagnosis. A biopsy is a minor surgery in which the doctor selects a typical lesion and removes a small piece of lesion tissue with a scalpel to make a pathological slice for observation to aid in diagnosis.
