What to expect from surgical excision for keratoacanthoma

A keratoacanthoma can grow quickly and may form a central keratin plug. Because its appearance can overlap with a type of skin cancer, clinicians commonly recommend removing it or taking an appropriate specimen for diagnosis. With excision, the area is numbed, the lesion and a planned margin are removed, and the wound is closed or dressed. The tissue is examined to clarify the diagnosis and whether the edges are clear. The final repair depends on the lesion's location and size, and a scar is part of the expected trade-off. Do not squeeze, shave, or apply home remedies to a rapidly changing lump.

Follow the dressing and cleaning instructions, and avoid activities that stretch or strike the wound. Keep pets, dirt, and unnecessary touching away from the site while it heals. Tell the clinician about medicines that affect bleeding before the procedure, and use only advised pain relief afterward. Attend stitch removal and the pathology discussion. Once healed, protect the scar from strong sun and check the surrounding skin for new, growing, crusted, or bleeding lesions. Report any change rather than waiting for it to settle on its own.

Seek prompt advice for bleeding that continues with pressure, wound separation, increasing pain, spreading redness, warmth, swelling, pus, or fever. Urgent care is appropriate for uncontrolled bleeding, severe swelling, or a reaction affecting breathing. Arrange review if a firm or crusted growth develops beside the scar, if the wound fails to heal, or if the pathology result has not been explained to you.

Ask why excision is preferred for your lesion, what margin and repair are planned, how long dressings or activity limits may be needed, and when the pathology result will be ready. Ask how the scar will be followed and what new skin changes warrant an early appointment.
