What should you know about internal warts?

A wart is a rough or smooth growth caused by a viral infection of the outer skin. In an internal or hard-to-see location, it may be hidden in a skin fold or near an opening such as the genital or anal area. Warts can be flesh-coloured, greyish, or irritated, and rubbing may cause soreness or spotting. Appearance alone cannot confirm the diagnosis; a clinician may inspect the area and consider testing or a small sample if the lesion is unusual.

Arrange a dermatology or sexual-health assessment rather than applying a home wart product to a mucosal surface. Keep the area gently clean and dry, avoid picking or shaving across the growth, and do not share towels or personal grooming items. Treatment depends on the location, size, number, and diagnosis. Options may include imiquimod, freezing, controlled removal, or electrosurgery; these treatments require advice about suitable skin and aftercare.

Seek prompt medical care for bleeding that does not settle, a rapidly enlarging or ulcerated growth, marked pain, pus, fever, or difficulty passing urine or stool. Make an appointment for any new internal growth, especially if it persists, returns after treatment, or appears during pregnancy or alongside a weakened immune system.

Ask which examination is needed, whether the location changes treatment, how to protect nearby skin, and whether a partner or household contact needs advice. You can also ask how recurrence will be monitored and which warning signs should bring you back sooner.
