Red Spots on Hands and Feet: Cherry Angioma Insights - Dermatology

More Info

---

Cherry angiomas, also known as senile angiomas or Campbell de Morgan spots, are benign growths of small blood vessels that appear as red or purple spots on the skin. They are quite common and can occur anywhere on the body, but are most frequently found on the trunk, arms, and scalp. The size of cherry angiomas can vary, typically ranging from a pinpoint to several millimeters in diameter. They are generally harmless and do not require treatment unless they become bothersome or for cosmetic reasons.

Based on the images you provided and your description of the red spots on your hands and feet, it is possible that these could be cherry angiomas, especially if they are small, red, and painless. However, it is essential to consult a dermatologist for an accurate diagnosis, as other skin conditions can present similarly. For instance, petechiae (small red or purple spots caused by bleeding under the skin), or other vascular lesions could also be responsible for the appearance of these spots.

The exact cause of cherry angiomas is not fully understood, but several factors may contribute to their development:
1. Aging: Cherry angiomas are more common in older adults, and their prevalence increases with age. This is likely due to the natural aging process of the skin and blood vessels.

2. Genetics: There may be a hereditary component, as cherry angiomas can run in families.

3. Hormonal Changes: Some studies suggest that hormonal changes, such as those occurring during pregnancy, may trigger the formation of cherry angiomas.

4. Environmental Factors: Exposure to certain environmental factors, such as chemicals or excessive sun exposure, may also play a role in their development.

In your case, since you mentioned that the spots are small (equal to or less than 1mm), they could indeed be cherry angiomas, especially if they are not accompanied by any other symptoms like itching, pain, or bleeding. However, it is crucial to monitor any changes in size, color, or number of these spots over time. If you notice any significant changes, or if new spots continue to appear, it would be wise to seek further evaluation from a healthcare professional.

While cherry angiomas are benign, if you are concerned about their appearance or if they become bothersome, dermatological treatments are available. Options include laser therapy, electrosurgery, or cryotherapy, which can effectively remove or reduce the appearance of these lesions.

In summary, while the red spots on your hands and feet may likely be cherry angiomas, a definitive diagnosis can only be made through a physical examination by a dermatologist. It is always best to err on the side of caution and seek professional advice, especially when it comes to changes in your skin. Regular skin checks and awareness of any new or changing lesions are essential components of maintaining skin health.
