Does surgical excision treat keratoacanthoma?

A keratoacanthoma is a rapidly enlarging, often dome-shaped skin growth with a central keratin plug. Its appearance can overlap with squamous cell carcinoma, so removal allows a pathologist to examine the whole lesion rather than relying only on its surface. Excision usually includes a margin of nearby skin. The result helps determine whether the lesion has been fully removed and whether further treatment or monitoring is appropriate.

Arrange prompt assessment for a new, fast-growing, crusted or crater-like lump, especially on sun-exposed skin. Do not squeeze, scrape, or try to burn it away. Discuss the recommended procedure, the likely scar, and whether the specimen will be examined in full. Once treated, follow wound instructions carefully and protect the area from sun while it heals.

Seek prompt medical review if the growth enlarges quickly, becomes painful, bleeds, or develops increasing crusting. After excision, call the clinic for persistent bleeding, wound separation, spreading redness, worsening pain, pus, or fever. A new lump at or near the scar should also be checked rather than assumed to be a recurrence.

Ask how the clinical appearance affects the differential diagnosis, whether the entire growth should be removed, what margin is planned, and when pathology will be discussed. Confirm scar care, activity restrictions, and how the treated site will be followed.
