What should you know about inverted seborrheic keratosis?

Seborrheic keratoses are common, non-cancerous growths sometimes called age warts, barnacles of ageing, or stuck-on growths. An inverted variant grows downward into the skin or has a central depression, so it may not have the familiar raised, waxy appearance. Colour can range from light brown to dark brown or nearly black, and texture may be rough or smooth.

A changing or atypical lesion should not be identified from a photograph alone. A dermatologist may use magnification and, when needed, remove a small sample for laboratory examination. This helps separate the growth from other lesions that can look similar.

Do not pick, scratch, or attempt to burn the growth at home. If it catches on clothing, bleeds after minor contact, itches, or is cosmetically bothersome, a dermatologist can discuss removal after assessment. Options may include [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/), [Curettage And Cautery](/treatments/surgical-dermatology/curettage-and-cautery/), or [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/).

The choice depends on the lesion's depth, location, appearance, and whether tissue needs to be preserved for diagnosis. The treated area may crust or change colour while it heals. Follow wound-care instructions and protect healing skin from unnecessary friction.

Book a dermatology review for a growth that enlarges, develops uneven colour or borders, repeatedly bleeds, becomes persistently painful, or changes quickly. Seek prompt attention for bleeding that does not settle with firm pressure, spreading redness, pus, or fever after a procedure. A lesion that looks different from your other growths also deserves an in-person check.

Does this need a biopsy before removal? Which technique fits its depth and location? What will the wound look like while healing, and how should I care for it? Could it return after treatment?
