Angiokeratoma

Angiokeratoma

Overview

Angiokeratomas are small, dark red to purple papules caused by dilated superficial blood vessels with an overlying hyperkeratotic (thickened) epidermis. They can appear as solitary lesions or in clusters and are most commonly found on the lower extremities, scrotum, or vulva. They are benign but may be confused with melanoma due to their dark coloration.

Key Symptoms

• Small dark red, purple, or black papules
• Rough or warty surface texture
• May bleed if traumatized
• Usually 1-5 mm in diameter
• Can appear solitary or in clusters
• Painless unless irritated or injured

Affected Areas

Lower extremities, Scrotum or vulva, Trunk, Fingers, Toes

Care Instructions

1. No treatment is usually required as angiokeratomas are benign.
2. Avoid picking or scratching to prevent bleeding.
3. See a dermatologist if a lesion changes rapidly or looks unusual to rule out melanoma.
4. Treatment options include electrocautery, laser therapy, or cryotherapy if desired.
5. Monitor for any new or changing lesions.
6. Protect lesions from trauma in areas prone to friction.
