Sore that won't heal on the Hand: Causes, Red Flags & When to Worry
Quick answer
A sore that won't heal on the hand… could be a warning sign of a sun-related skin cancer like basal cell or squamous cell carcinoma. It might also be a stubborn patch of severe contact dermatitis or a deep fungal infection. The biggest red flag to watch for is a crusty bump that bleeds easily, scabs over, and then bleeds again without completely closing. While hands naturally heal slower because they are constantly moving, any wound lasting longer than four weeks requires a doctor's attention.
Why a sore that won't heal on the hand is different
The backs of the hands accumulate sun damage almost as quickly as the face, while the palms and finger webs are common sites for eczema, fungal infections and contact dermatitis.
Hand sores behave entirely differently than wounds elsewhere due to unique anatomy and constant exposure. The thin skin on the backs of your hands catches driving UV rays, meaning sun damage accumulates almost as quickly as on the face. This makes skin cancers highly likely for non-healing spots. Conversely, chronic issues like venous leg ulcers or diabetic foot ulcers are extremely rare here. On the palms and finger webs, problems stem from friction and stripped barriers. Frequent hand-washing, trapped sweat from gloves, and chemical exposure make contact dermatitis and fungal infections the primary culprits. While a stubborn sore is concerning, remember that hands endure endless abuse. Many wounds simply struggle to close because the skin is constantly stretching and bending.
The most common day-to-day triggers in this area are frequent hand-washing, glove and chemical exposure, driving sun exposure — each of which can produce or worsen a sore that won't heal here.
Most likely causes
Basal cell carcinoma
Classic "non-healing sore" — often on the face or scalp.
Squamous cell carcinoma
Scaly, sometimes ulcerated lesion on sun-damaged skin.
Venous leg ulcer
Shallow ulcer above the inner ankle in older adults.
Diabetic foot ulcer
Painless ulcer on pressure points in diabetes.

The most common causes are Basal cell carcinoma, Squamous cell carcinoma, Venous leg ulcer, Diabetic foot ulcer. Because the hand sees frequent hand-washing and glove and chemical exposure, these triggers also raise the likelihood of a sore that won't heal appearing here.
Most non-healing sores are harmless. However, you should seek a dermatology review if you notice: Any sore that hasn't healed in 4 weeks; Recurs in the exact same spot; Bleeds, oozes or has rolled raised edges.
Use the ABCDE rule — Asymmetry, irregular Borders, multiple Colours, Diameter over 6 mm, and Evolution (any change). On the hand, also watch for sores that don't heal, pearly bumps with visible blood vessels, or any lesion that bleeds repeatedly. A free AI mole checker can help you track changes over time.
Try: Keep clean and covered with a non-stick dressing; Photograph weekly for comparison; See a clinician at the 4-week mark, sooner if growing. Avoid picking or squeezing, and photograph the area today so you can compare in 2–4 weeks.
Book a review if the spot is growing, changing colour, bleeding, painful, or persists more than 4–6 weeks. Same-day care is needed for spreading redness with fever, breathing trouble, or non-blanching purple spots.
