Pictures of Keratoacanthoma Skin Cancer: What to Know

Keratoacanthoma often begins as a small, firm bump and can enlarge quickly over a short period. It may have a smooth raised rim around a central plug, with a colour ranging from skin-coloured to pink or red. It commonly develops on sun-exposed skin, although appearance alone cannot distinguish it from other growths. Sun-damaged skin can add context, but it does not make a diagnosis.

Do not squeeze, scrape, or try to remove the central plug yourself. Photograph the area beside a ruler for comparison, record when you first noticed it, and protect it from rubbing and sun exposure. Book a prompt dermatology assessment. Depending on the examination and tissue findings, treatment may include [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/) or [Curettage And Cautery](/treatments/surgical-dermatology/curettage-and-cautery/).

Arrange prompt medical review for a lump that grows quickly, bleeds, crusts repeatedly, becomes tender, or fails to heal. Seek earlier attention if it is near the eye, nose, lips, fingers, or another area where swelling or treatment could affect function. Urgent care is appropriate for uncontrolled bleeding, severe pain, or signs of spreading infection.

Could this be keratoacanthoma or another lesion? Do I need a biopsy or removal? Which treatment would suit its size and location? How will the area be cared for afterward, and when should it be checked again?
