Early Keratoacanthoma: What to Know

Keratoacanthoma is a skin growth that often appears as a firm, rounded, red or skin-coloured lump with a central plug of keratin. It commonly occurs on sun-exposed skin such as the face, ears, forearms, or backs of the hands. The growth may change noticeably over a short period and can be tender, crusted, or bleed after rubbing. Its appearance can overlap with squamous cell carcinoma and other lesions, so a photograph or visual guess cannot settle the diagnosis.

Sun-damaged skin can increase the background risk of several lesions, but the presence of sun exposure does not identify a particular lump. Avoid squeezing, scraping, or covering it with irritating home remedies.

Arrange a prompt dermatology assessment and note when the lump began, how it has changed, and whether it bleeds or hurts. The clinician may recommend sampling or removing the lesion so its cells can be examined. Treatment can include curettage and cautery or surgical excision, chosen according to the lesion’s size, site, borders, and clinical findings. Keep it protected from friction and use sensible sun protection while waiting.

Seek prompt care for a lump that enlarges quickly, repeatedly bleeds, becomes ulcerated, develops increasing pain, or is near the eye, nose, or ear. Get urgent help for uncontrolled bleeding, severe swelling, fever, or rapidly spreading redness. Do not delay assessment because the lump is small or painless; the pattern of growth is a key reason for examination.

Ask whether the lesion needs a biopsy or complete removal, what the likely options are for its location, and how the wound will be cared for afterward. Tell the clinician about previous skin cancers or unusual lesions, sun exposure, medicines that affect bleeding, and any recent change in size, crusting, or tenderness.
