Keloid on shoulder: what to know

Keloids form when the body continues making dense scar tissue after a cut, injection, operation, acne spot, or other skin injury has closed. On the shoulder, movement, clothing straps, and rubbing can keep a scar irritated. The area may be firm, shiny, itchy, sore, darker, or lighter than surrounding skin, and its edges can extend past the original wound. A raised scar is not automatically a keloid; a clinician may need to distinguish it from a hypertrophic scar, inflamed cyst, or another skin lump. Photographing its size and noting itch or tenderness can help show change.

Protect the area from rubbing and picking, and keep healed skin moisturised if that suits you. Do not shave across it aggressively or apply caustic products. A dermatologist may discuss steroid injections, cryotherapy, laser treatment, pressure methods, or surgery based on thickness, symptoms, skin tone, and previous scar behaviour. Surgery alone can be followed by further scar growth, so recurrence prevention deserves a clear plan. See [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) and [Keloid Removal Surgery](/treatments/surgical-dermatology/keloid-excision/).

Book an assessment if the shoulder scar is enlarging, painful, itchy, restricting movement, or repeatedly catching on clothing. Seek prompt care for warmth, spreading redness, pus, fever, sudden marked swelling, or bleeding that does not settle with gentle pressure. A rapidly changing or ulcerated area needs examination rather than self-treatment.

Ask what caused the scar, whether it is a keloid or another lump, how treatment may affect pigmentation, how many visits may be needed, and what aftercare will reduce renewed growth.
