Red Moles on Arms: Are They Normal or a Concern?

Red mole on the arm?

Hello Doctor: Over the past year or two, I have developed several small red moles in different areas on my arms.
My mother, who is 60 years old, has also developed similar red moles over the years.
We both visited the dermatology department at Chang Gung Memorial Hospital, but the doctor only mentioned that it is due to skin aging.
Is this correct? Are these red moles normal?

Based on your description, your issue may be a type of angioma, commonly referred to as a cherry angioma due to its cherry-like color.
It is often seen in older individuals, which has led to the belief that it is associated with aging.
In Chinese culture, it is considered a symbol of longevity (of course, one must live long enough to develop it), and is therefore also known as a "blessing mole." Essentially, this is a benign tumor and does not affect health.

More Info

Red moles, or cherry angiomas, are common benign growths that can appear on the skin, particularly as people age. They are typically small, round, and bright red or purple in color. The appearance of these moles can be attributed to a variety of factors, including genetics, hormonal changes, and environmental influences. Given that you mentioned your mother has also developed similar red moles, it is likely that there is a genetic component involved.

Cherry angiomas are composed of small blood vessels and are generally harmless. They can occur anywhere on the body but are most commonly found on the trunk, arms, and scalp. While they are usually asymptomatic, some individuals may experience minor irritation if the mole is frequently rubbed or scratched. In most cases, these moles do not require treatment unless they become bothersome or if there is a concern about their appearance.

The fact that a dermatologist has previously evaluated your moles and deemed them a result of skin aging is consistent with common medical understanding. As we age, our skin undergoes various changes, including the development of these benign growths. It is important to note that while cherry angiomas are generally harmless, any new skin growths or changes in existing moles should be monitored. If you notice any changes in size, shape, color, or if the mole becomes painful or bleeds, it is advisable to seek further evaluation from a dermatologist.

In terms of prevention, there is no specific way to prevent cherry angiomas from forming, as they are largely influenced by genetic and age-related factors. However, maintaining healthy skin through proper hydration, sun protection, and a balanced diet can contribute to overall skin health.

If you have concerns about the appearance of these red moles or if they are increasing in number, it may be beneficial to consult with a dermatologist for a thorough examination. They can provide you with personalized advice and, if necessary, discuss options for removal or treatment, although this is typically only recommended for cosmetic reasons.

In summary, red moles on the arms, particularly if they resemble cherry angiomas, are generally normal and a common occurrence as part of the aging process. Given your family history, it is likely that this is a hereditary trait. However, ongoing monitoring of any skin changes is essential for maintaining skin health and addressing any potential concerns promptly.
