Cherry angiomas are common skin growths that typically appear as small, bright red spots. While generally harmless, these growths can sometimes be a cosmetic concern or become irritated.
Understanding Cherry Angiomas
Cherry angiomas are small, benign vascular lesions that appear as bright red, blue, or purple papules on the skin, typically ranging from 0.1 to 1 centimeter in diameter. They are composed of clustered small blood vessels, which give them their characteristic color. These growths can occur almost anywhere on the body, though they are most frequently observed on the trunk, arms, and legs.
While the direct cause of cherry angiomas is not fully understood, their development is often linked to aging, with a significant increase in prevalence after age 30. Genetics also play a role, as does exposure to certain chemicals or hormonal changes. Despite their appearance, cherry angiomas are not typically a sign of underlying health issues.
When to Seek Removal
Individuals often consider removing a cherry angioma primarily for cosmetic reasons, as these growths are medically benign and pose no health risk. They are not contagious and generally do not cause discomfort. However, removal might also be sought if an angioma is located in an area prone to irritation or bleeding, such as from clothing friction or shaving.
Additionally, if there is any uncertainty about the diagnosis of a skin lesion, a healthcare professional should be consulted to confirm it is indeed a cherry angioma and not a more serious condition. While cherry angiomas rarely change appearance, any sudden changes in size, color, shape, or new bleeding should prompt an evaluation by a dermatologist.
Professional Removal Options
Several medical procedures are available for the removal of cherry angiomas, each targeting the clustered blood vessels. These procedures are typically performed in a dermatologist’s office under local anesthesia.
- Cryotherapy uses liquid nitrogen to freeze the angioma, destroying blood vessels. The treated area may blister and scab, with the angioma falling off as the skin heals, usually within 7 to 10 days.
- Electrocauterization uses an electric current to generate heat, burning and sealing blood vessels. This method is effective for smaller angiomas and helps control bleeding.
- Laser therapy employs concentrated light beams, such as pulsed dye lasers (PDL), to destroy blood vessels without significantly damaging surrounding skin. This procedure is often quick, with patients experiencing a sensation similar to a mild rubber band snap.
- Shave excision uses a sharp blade to shave off the angioma at the skin’s surface. This technique is often used for larger or raised angiomas, with electrocauterization sometimes applied afterward to stop bleeding.
- Surgical excision is less common for typical cherry angiomas but may be considered for larger or deeper lesions, or if a biopsy is needed.
Post-Removal Care and Expectations
After a professional removal procedure, the treated area may show temporary redness, swelling, or bruising. A scab commonly forms. This scab typically resolves within one to two weeks, but complete healing can take longer, sometimes up to a month or more.
General aftercare instructions include keeping the treated area clean and dry. Avoid picking or scratching scabs, as this can increase the risk of scarring or infection. Protecting the treated area from direct sun exposure with sunscreen and protective clothing is advised to minimize potential pigmentation changes. Avoiding strenuous activity, hot showers, and swimming for a few days post-procedure can further support healing. While scarring is possible, it is usually minimal and tends to fade over time.
Non-Medical Approaches and Prevention
There are no scientifically proven home remedies or natural methods that can effectively remove cherry angiomas. Attempting to remove these growths at home using unproven methods is not recommended due to the potential for infection, bleeding, or scarring, and can complicate professional diagnosis if the lesion is not a cherry angioma.
Cherry angiomas are generally not preventable, as their development is often linked to factors such as aging and genetics. There is no definitive prevention method.
