User:Mr. Ibrahem/Cherry angioma

Cherry angioma is a small red to purple dome-shaped bump in the skin. There are usually several, typically on the chest, back, and arms, and range between 0.5mm to 6mm in size. There are generally no symptoms; though if scratched, they may bleed.

The cause is unclear. They may appear during pregnancy and resolve afterwards. They are a harmless tumor, containing an abnormal proliferation of small blood vessels. Diagnosis is based on appearance, which may be supported by dermoscopy.

Treatment is not usually necessary. They may be removed with electrocauterization, light electrodesication, laser ablation, or shave excision, but this may leave a scar. Rarely, in unclear cases, they may be removed to rule-out cancer.

They are the most common kind of angioma, occurring in most adults over 30 years. More tend to appear with age. Males and females are affected with similar frequency. Campbell de Morgan, a British surgeon, first described them in 1872.
