Where do HPV pimples grow

Acne caused by HPV infection usually appears around the genitals, anus, and oral mucosa, and may be associated with genital warts or flat warts. The main skin manifestations include papules on the external genitalia, perianal growths, and verrucous hyperplasia of the oral mucosa. HPV infection should be distinguished from common acne, which is more common in the face, chest, and back.

1. Low risk HPV infection in the genital area

is common in the external genitalia and perineum, manifested as soft pink cauliflower like growths. It is more common in males in the frenulum and coronal sulcus of the foreskin, and more common in females in the labia minora and vaginal opening. This type of skin lesion is contagious and should be avoided from scratching to prevent self inoculation from spreading.

2. Perianal

Perianal genital warts are mostly caused by HPV6/11 type, with circular distribution of papillomatous hyperplasia visible. Commonly seen in individuals who engage in anal sex or have poor local hygiene, it may be accompanied by discomfort or bleeding during bowel movements. Attention should be paid to distinguishing it from hemorrhoid skin folds. Diagnosis requires acetic acid white test or pathological examination.

3. Oral mucosa

Oral HPV infection is more common in the lingual frenulum, buccal mucosa, and other areas, manifested as white or pink flat papules. High risk HPV16/18 may be associated with oropharyngeal cancer. Long term smokers and drinkers have an increased risk of developing persistent oral ulcers that require timely biopsy.

4. Other skin areas

Common warts can occur on fingers, nails, and other areas, presenting as rough keratinized papules. Flat warts are more common on the back of the face and hands, appearing as clusters of skin colored flat papules. Although these lesions are associated with HPV, the virus subtype is different from genital warts, and the infectivity is relatively low.

5. Non HPV related acne

Common acne is mainly distributed in areas with abundant sebaceous glands, such as the forehead and T-zone of the nose. Propionibacterium acnes infection leads to abnormal keratinization of hair follicles, resulting in the formation of acne or inflammatory papules. The difference between acne and HPV warts is that acne is accompanied by clogged pores, and pressing can cause lipid plugs to be expelled. Keeping the affected area clean and dry can help prevent the spread of HPV warts. It is recommended to choose cotton breathable underwear. Patients with genital warts should suspend sexual activity until cured, and their sexual partners should be checked simultaneously. When unexplained skin growths appear, timely medical attention should be sought for HPV typing testing to avoid misdiagnosis as common acne and delayed treatment. Daily attention to enhancing immunity, regular sleep and balanced diet have a positive effect on virus clearance.
