Is a keratoacanthoma painful?

These lesions often form a firm, raised bump with a central keratin plug. Pressure from the plug, stretching of the surrounding skin, surface cracking, or inflammation can create soreness. A lesion on a finger, face, scalp, or another frequently touched area may hurt because it is disturbed repeatedly.

Pain can also come from an open surface, infection, or a different skin problem. A painful lump should therefore be examined rather than labelled from symptoms alone. A clinician may use dermoscopy and a biopsy to separate keratoacanthoma from other growths, including squamous cell carcinoma.

Do not squeeze, scrape, or try to remove the central plug. Covering the lesion with a clean, non-stick dressing can reduce rubbing, and ordinary pain relief may be suitable for some people if a pharmacist or clinician confirms it is safe with their medicines and health conditions.

Book a dermatology assessment soon, particularly if the bump is growing quickly or has not been diagnosed. Treatment may involve [Curettage And Cautery](/treatments/surgical-dermatology/curettage-and-cautery/) or [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/). Reduce additional ultraviolet exposure by using shade, protective clothing, and guidance about [Sun-Damaged Skin](/conditions/photoaging/).

Contact a clinician promptly for escalating pain, bleeding, pus, spreading warmth or redness, a foul smell, or a wound that is not settling. Seek urgent care for heavy bleeding, fever with worsening redness, or severe pain. Do not wait for routine review if the lesion is close to the eye, nostril, mouth, or ear and is changing rapidly.

Ask what features make the lesion likely to be a keratoacanthoma, whether a biopsy is needed, and whether the painful surface is infected or simply inflamed. Ask how soon it should be treated, which procedure suits its location, and what symptoms after treatment should trigger a call.
