What should you know about seborrheic keratosis irritated and inflamed?

Seborrheic keratoses are non-cancerous surface growths that can catch on clothing, jewellery or a towel. Friction may make the area red, sore, scaly or lightly bleeding. Inflammation can also follow scratching or accidental trauma. Those features can overlap with other skin conditions, so appearance alone cannot confirm the diagnosis, especially when the growth is newly changing.

Keep the area clean and avoid picking, shaving over it or applying strong acids or home cautery. A bland moisturiser may reduce friction, and loose clothing can protect a lesion on the trunk. Arrange a dermatology assessment if the irritation persists, returns repeatedly or interferes with sleep. If removal is appropriate, a clinician may discuss cryotherapy, curettage and cautery, or electrosurgery; the choice depends on the lesion and the surrounding skin.

Seek prompt medical review for bleeding without clear rubbing, rapid enlargement, marked colour variation, an irregular outline, persistent pain, pus, spreading redness or a sore that does not settle. Urgent care is sensible if redness is rapidly spreading or you feel unwell. Do not assume that inflammation proves cancer or that a familiar-looking growth is harmless without an examination.

Ask whether the lesion has the typical features of seborrheic keratosis, whether it needs dermoscopy or sampling, and which removal option would leave the least irritation in its location. Mention any recent bleeding, colour change, repeated snagging, skin treatments and medicines that affect healing.
