Causes
There is no single proven cause of acral nevi. Genetics, UV exposure, hormonal changes, radiation, infections, and repeated minor injuries to the skin may all play a role in their appearance and growth.

An acral nevus is a benign mole that appears on the palms of the hands or soles of the feet. It is usually small, evenly colored, and stable over time, and most do not turn into melanoma. Because melanoma can also appear on palms and soles, any new or changing spot in these areas should be checked by a dermatologist.

Risk Factors
A typical acral nevus is considered safe and does not by itself carry a higher melanoma risk than normal skin. The main danger is confusing an early acral melanoma with a benign nevus, so any change in size, shape, color, or sensation should be checked promptly.
Treatment
Most acral nevi do not need treatment and can simply be monitored. If a lesion is suspicious, repeatedly traumatized, or cosmetically bothersome, surgical removal with histology is recommended, while laser or freezing methods are generally avoided on these moles.
Prevention
You cannot fully prevent acral nevi, but you can reduce risks by protecting your skin from excessive UV, avoiding chronic friction and trauma, and limiting unnecessary radiation exposure. Regular self‑checks, photo monitoring, and timely visits to a dermatologist help catch any suspicious changes early.
When to See a Doctor?
See a dermatologist if you notice a new spot on your palm or sole, or if an existing acral nevus changes in size, shape, color, or starts to itch, hurt, or bleed. Even if it looks benign, a first‑time evaluation is wise because acral melanoma can look similar in early stages.
Urgency
A stable, typical acral nevus is not an emergency and can be checked at a routine dermatology visit. If the spot is new in an adult, or you see rapid change, irregular shape, very dark or uneven color, or symptoms like pain or bleeding, you should book an urgent (but not ER‑level) dermatology appointment.

Low RiskBlackhead
An open comedone, or blackhead, is a small plug of oil and dead skin that blocks the opening of a pore and turns dark when exposed to air. It is a non‑inflamed form of acne and most often appears on the face, neck, chest, back, and shoulders. Blackheads are usually harmless but can be a cosmetic concern and may progress to inflamed pimples if bacteria overgrow.
Harmless & Common
Low RiskMilia
Milia are tiny, white or yellowish cysts just under the surface of the skin, most often seen on the face. They are harmless, not infectious, and usually cause only cosmetic concerns rather than health problems.

Low RiskWhitehead
A closed comedone (whitehead) is a small clogged pore where sebum and dead skin cells are trapped under a thin layer of skin. It looks like a tiny, pale or skin‑colored bump without a black dot in the center and is considered a mild, non‑inflamed form of acne.
Harmless & Common
Low RiskAge spot wart
Seborrheic keratosis is a very common benign skin growth that looks like a stuck‑on, warty or waxy spot on the skin. It usually appears after age 40–50, often in many spots, and does not turn into skin cancer in most people.
