Red moles are common skin growths that many individuals notice appearing on their bodies over time. These small, often brightly colored spots are generally harmless. Understanding their nature provides clarity and reassurance.
Understanding Red Moles
Red moles, often referred to as cherry angiomas, are benign growths composed of small blood vessels. These vascular lesions are also known by other names, such as senile angiomas or Campbell de Morgan spots. They typically present as small, dome-shaped bumps or flat spots that can range in color from bright red to purplish or even blue.
Cherry angiomas commonly measure between 1 to 5 millimeters in diameter and can appear anywhere on the body. They are frequently found on the torso, arms, legs, and shoulders. While cherry angiomas are the most prevalent type of red mole, another related lesion is the spider angioma, characterized by a central red spot with fine, radiating blood vessels resembling a spider’s legs. Unlike cherry angiomas, spider angiomas will temporarily disappear or “blanch” when pressure is applied to their center.
Factors Contributing to Their Appearance
Red moles develop due to several factors. A prominent factor is the natural aging process, with these growths becoming more frequent after the age of 30. Genetic predisposition can also play a role, as red moles may run in families.
Hormonal fluctuations, such as those experienced during pregnancy, can lead to an increase in their number. In some instances, exposure to certain chemicals like bromides or nitrogen mustard has been associated with their appearance. The sudden development of numerous red moles, known as eruptive angiomas, might also signal an underlying medical condition or a side effect of certain medications.
When to Seek Medical Advice
While most red moles are benign and pose no health concerns, it is prudent to monitor them for any changes. A visit to a healthcare provider is recommended if a red mole changes in size, shape, or color. Other signs that warrant medical evaluation include bleeding, itching, or pain associated with the mole.
The sudden appearance of multiple red moles, especially spider angiomas, can sometimes be an indicator of an underlying health issue. For example, numerous spider angiomas may be associated with liver conditions. Although red moles are typically not cancerous, a medical professional can differentiate them from other skin lesions, including skin cancer, through a thorough examination.
Options for Removal
Removal of red moles is typically pursued for cosmetic reasons or if they become irritated, bleed, or are frequently snagged by clothing. Attempting to remove these growths at home is not advised, as it can lead to infection or scarring. Medical professionals offer several safe and effective methods for removal.
Cryosurgery involves freezing the mole with liquid nitrogen. This procedure is quick and generally well-tolerated, though the treated area may show temporary redness, swelling, or blistering before healing. Electrocautery uses an electric current that burns and dries out the tissue.
Laser therapy is another option, utilizing concentrated light beams to destroy the blood vessels within the mole through heat, often resulting in minimal discomfort and good cosmetic outcomes. For some red moles, a shave excision, which involves carefully shaving off the growth, may be performed.
