Pseudomonal warts are a group of skin and mucosal lesions that occur in the external genital area of men and women and are easily confused with condyloma acuminata. These lesions include pearly penile papules and parapapapillary papules in males and villous labia minora in females. The former is a warty growth caused by human papilloma virus infection and can be transmitted through sexual contact, while pseudo warts are generally considered to be related to abnormal physiological development or long-term inflammatory stimulation such as circumcision and vulvovaginitis, and are not contagious. Penile pearly papules occur mainly at the border of the glans and coronal sulcus. The damage is 1-3 mm in size papules with a garden and smooth tip, some of which may be hairy or filiform. The papules are not fused and may be arranged in dense rows or rows that may partially or completely surround the glans. The color of the lesions is mostly pearly white, with a few being light red or skin colored. Paronychia papules occur on both sides of the penile tether, and the majority are symmetrical, ranging from 1-5 on each side. The lesions are corn-sized papules with a smooth surface. There are no conscious symptoms. Vulvar labia minora occurs mainly on the inner side of the labia minora on both sides, and rarely in and around the vaginal opening, vestibule, and urethra. The lesions are characterized by 1-2 mm sized clustered papules, such as caviar-like, with a granular sensation when touched; some lesions may be arranged in a linear or band-like pattern, and some lesions may also be villi-like protrusions or polyp-like or finger-like. The surface of the lesion is smooth and light red in color. The majority of patients have no conscious symptoms, but a few may have mild itching. Pseudomonal warts are not a sexually transmitted disease and generally do not require treatment. The pseudo warts can be distinguished from the condyloma acuminata by the characteristics of the rash, the white acetate test and the virus test. The main prevention and treatment principle is to keep the local cleanliness and hygiene, keep the local dry environment, and avoid stimulation of the lesion friction. For larger rashes, laser or cryotherapy can be used.
