Cherry angiomas are common, benign skin growths that often appear as small, red spots. These proliferations of blood vessels typically develop over time and are generally considered harmless. While their appearance can sometimes cause concern, cherry angiomas usually do not itch or cause any discomfort.
What Are Cherry Angiomas and Do They Itch
Cherry angiomas are small, bright red to purple spots or papules that commonly appear on the trunk and limbs. These growths are typically pinpoint in size but can grow to several millimeters in diameter, appearing as either flat or slightly raised lesions. They originate from a benign overgrowth of capillaries, which are tiny blood vessels, giving them their characteristic reddish color.
Cherry angiomas are generally asymptomatic, meaning they typically do not cause pain or discomfort. They are very common, especially as individuals age, with an estimated 75% of people over 75 years old having them. The presence of cherry angiomas is usually a normal part of the aging process and does not indicate any underlying health issues.
Reasons Why a Cherry Angioma Might Itch
While cherry angiomas themselves are not inherently itchy, certain external factors can lead to irritation and a sensation of itching. This can occur if the angioma is located in an area prone to friction, such as along a bra line or belt line, where clothing can rub against it. Constant rubbing may irritate the delicate skin around or on the angioma, leading to mild inflammation.
Accidental scratching or trauma to the cherry angioma can also cause it to become irritated and itchy. If the lesion is picked at, it may bleed slightly and become inflamed, which can trigger an itching sensation. The itching is typically a direct result of external irritation or minor injury to the angioma or surrounding skin.
When to Seek Medical Advice
Although cherry angiomas are typically harmless, it is advisable to consult a healthcare professional if you notice any changes in an existing lesion. Medical advice is recommended if a cherry angioma changes in size, shape, color, or texture. Additionally, if the angioma begins to bleed spontaneously, becomes painful, or develops a crust or sore, a professional evaluation is recommended.
Persistent, unexplained itching associated with a cherry angioma should also prompt a visit to a doctor. It is also important to seek medical advice if there is any uncertainty about the diagnosis of a skin growth, to ensure it is indeed a benign cherry angioma and not another skin condition.
