Condylomata acuminata, also known as perianal warts, is a viral disease affecting certain parts of the body such as the anus with the anal canal, the external genitals and the cervix.
This viral disease is one of the most common sexually transmitted diseases. The pathogen is the human papilloma virus (HPV).
It infects epithelial cells of the skin/mucosa and may trigger tumor-like growth in the infected cells in the form of warts.
More than 100 different subtypes of this HP virus exist, with certain subtypes having a particular risk potential for dysplasia and malignant transformation.
Especially in immunosuppressed patients (e.g., HIV patients, patients under medical immunosuppression), HPV infection may lead to dysplasia and even malignant degeneration (anal carcinoma), of the skin/mucosa.
