Cherry angiomas are common skin growths that affect many people worldwide. These small, bright red spots typically appear on the torso, arms, and legs, and while they’re generally harmless, their presence can cause concern for those unfamiliar with them. Understanding the nature of cherry angiomas, including their causes, symptoms, and available treatments, is crucial for anyone who may encounter these distinctive skin lesions.
This article delves into the world of cherry angiomas, exploring their origins and risk factors. It also examines the characteristic signs that help in identifying these benign growths and discusses the diagnostic process. Additionally, the piece outlines various treatment options available for those who wish to remove or minimize the appearance of cherry angiomas, providing readers with comprehensive information to make informed decisions about their skin health.
What is Cherry Angioma?
Cherry angiomas, also known as Campbell de Morgan spots or senile angiomas, are benign skin growths made up of blood vessels. These noncancerous lesions are a common type of acquired vascular proliferation of the skin, typically appearing in adults after the age of 30.
Definition
A cherry angioma is a small, round, bright red to purple bump on the skin, ranging from 1 to 5 millimeters in diameter. These growths are made up of an abnormal proliferation of blood vessels and are often surrounded by a pale halo.
Appearance
Cherry angiomas are dome-shaped papules with a distinct appearance. They are usually bright red in color, earning them the name “cherry” due to their resemblance to the fruit. The lesions are well-demarcated and may be separated by septa. Some cherry angiomas may appear more purple or blue, especially when the individual experiences hypoxia.

Common locations
Cherry angiomas can develop on various parts of the body, but they are most commonly found on the trunk, particularly the chest and back. They may also appear on the arms and legs, but rarely on the face, hands, or feet. These lesions can occur as single spots or in clusters, sometimes forming polypoid angiomas when multiple growths are adjoined.
Although the exact cause of cherry angiomas remains unknown, they are associated with aging and are more prevalent in older adults. While they may be unsightly, cherry angiomas are generally harmless and do not require treatment unless they are frequently irritated or bleeding, or if the individual desires removal for cosmetic reasons.
Causes and Risk Factors
The exact cause of cherry angiomas remains unknown, but several factors may contribute to their development:
Age-related factors
Cherry angiomas are more common in adults over 30 years old, with incidence increasing dramatically after the age of 40. As people age, the size and number of cherry angiomas tend to increase.
Genetic predisposition
Genetics may play a role in the development of cherry angiomas. Studies have identified somatic missense mutations in the GNAQ (Q209H, Q209R, R183G) and GNA11 (Q209H) genes in these lesions. Additionally, many individuals with cherry angiomas have family members who are similarly affected.

Hormonal changes
Hormonal fluctuations, particularly increased levels of estrogen, may contribute to the formation of cherry angiomas. This is evident in the high incidence of cherry angiomas among pregnant women and those taking oral contraceptives.
Environmental triggers
Exposure to certain chemicals and treatments has been linked to the development of cherry angiomas. These include:
- Topical nitrogen mustard, used for treating vitiligo
- Cyclosporine, an immunosuppressant medication
- Bromides and other chemicals, increasingly used in tropical climates
Other factors that may influence cherry angioma development include:
- Chronic graft-host disease
- Lymphoproliferative diseases and multicentric Castleman disease (MCD)
- Human herpesvirus-8 (HHV8) infection
- Sun exposure, which may lead to cellular changes that promote the growth of endothelial cells
While the exact cause of cherry angiomas remains elusive, understanding the potential risk factors can help individuals and healthcare professionals better manage and treat these benign skin growths.
Symptoms and Diagnosis
Cherry angiomas are typically asymptomatic and do not cause any discomfort. However, understanding their visual characteristics is crucial for identifying these benign skin growths.
Visual characteristics
Cherry angiomas appear as small, round, bright red to purple bumps on the skin, ranging from 1 to 5 millimeters in diameter. These dome-shaped papules are well-demarcated and may be surrounded by a pale halo. They can occur as single spots or in clusters, sometimes forming polypoid angiomas when multiple growths are adjoined.
While cherry angiomas are usually painless, they may occasionally itch or bleed if scratched or injured. If you notice persistent itching or bleeding, it is essential to consult a healthcare provider to rule out other potential causes, such as allergies, acne, or skin infections.
When to see a doctor
Although cherry angiomas are generally harmless, it is important to seek medical attention if:
- You are unsure whether the growth is a cherry angioma or another skin condition, such as melanoma.
- The angioma frequently bleeds due to injury or irritation.
- You desire removal for cosmetic reasons.
Diagnostic methods
Diagnosing cherry angiomas is typically straightforward and can be done through a visual examination of the skin by a healthcare professional. In most cases, no additional tests are required to confirm the diagnosis.
However, if there is uncertainty about the nature of the growth, a skin biopsy may be performed. This involves removing a small sample of the lesion for microscopic examination to rule out other skin conditions and confirm the presence of a cherry angioma.
By familiarizing yourself with the symptoms and diagnostic methods for cherry angiomas, you can better understand these common skin growths and make informed decisions about their management and treatment.
Treatment Options
Cherry angiomas are generally harmless and do not require treatment. However, if they frequently bleed, cause discomfort, or are cosmetically undesirable, several treatment options are available.
Observation
In most cases, cherry angiomas do not necessitate immediate treatment. If the lesions are asymptomatic and do not bother the individual, they can be left alone. Regular monitoring by a dermatologist can help detect any changes in size, shape, or color that may warrant further investigation.

Removal techniques
If removal is desired, the following techniques may be employed:
- Electrocauterization: This method uses an electric current to generate heat, destroying the abnormal tissue and cauterizing the area to minimize bleeding. A local anesthetic ensures comfort during the procedure.
- Cryotherapy: Liquid nitrogen is applied to the cherry angioma, causing it to freeze and ultimately destroying the cells as it thaws. Multiple applications may be necessary for larger lesions. Blistering or scabbing may occur post-treatment, and proper aftercare is crucial.
- Laser therapy: Highly concentrated light energy is used to precisely target and destroy the cherry angioma cells while minimizing damage to surrounding healthy tissue. Laser therapy offers reduced discomfort, swelling, and scarring compared to other methods.
- Surgical excision: The Mohs surgical technique involves removing the cherry angioma along with a thin layer of surrounding skin. This minimally invasive approach ensures comfort, reduces the need for stitches, and promotes faster healing. The excised tissue can also be examined for cancerous cells.
Post-treatment care
Following any cherry angioma removal procedure, it is essential to adhere to the dermatologist’s aftercare instructions to ensure proper healing and minimize the risk of infection or adverse effects. This may include keeping the treated area clean and dry, applying prescribed ointments, and protecting the skin from sun exposure.
Conclusion
Cherry angiomas, while generally harmless, have a significant impact on many people’s lives. This article has explored their causes, symptoms, and available treatments to give readers a clear picture of these common skin growths. Understanding the nature of cherry angiomas can help individuals make informed decisions about their skin health and whether to seek treatment.
For those who choose to address their cherry angiomas, several effective options are available. From observation to removal techniques like cryotherapy and laser therapy, individuals can work with healthcare professionals to find the best approach for their unique situation.
