Angiokeratoma

Symptoms

• Small, dark red to purple bumps on the skin, often with a rough or scaly texture
• Commonly appears on various body parts, such as the legs, genitals, and torso
• Usually painless, but may sometimes itch or bleed when irritated
• Can occur in clusters or be scattered across the skin
• Some forms, such as in Fabry disease, may be associated with other symptoms like burning pain in the hands and feet

Cause

• Develops due to the dilation of small blood vessels in the skin, often combined with thickening of the epidermis
• Can occur spontaneously, especially in older adults
• Sometimes linked to genetic conditions, such as Fabry disease
• May arise due to increased pressure in the blood vessels, such as in chronic venous insufficiency

Diagnosis

• A doctor can recognize angiokeratomas based on their characteristic appearance
• In some cases, a dermatoscope may be used for a more detailed inspection
• If there is uncertainty about the diagnosis, a skin biopsy may be performed to rule out other skin conditions
• If a genetic disorder is suspected, additional tests, such as genetic screening, may be necessary

Treatment

• Treatment is usually not required if the lesions do not cause discomfort
• For cosmetic or symptomatic reasons, angiokeratomas can be removed using:
• Laser therapy to destroy the blood vessels
• Electrocoagulation to burn the lesions
• Cryotherapy (freezing with liquid nitrogen)
• Surgical removal for larger or persistent lesions
• In Fabry disease, treatment may be necessary to manage other symptoms

Self-Care Tips

• Avoid excessive friction or scratching to prevent bleeding or irritation
• Wear loose-fitting clothing to reduce friction on sensitive areas
• Moisturize the skin with a gentle cream to prevent dryness and irritation
• Consult a doctor if angiokeratomas increase rapidly, start bleeding, or are accompanied by other unusual symptoms
• If underlying venous issues are present, compression stockings may help reduce pressure in the blood vessels
