Do Hemangiomas Change Color Over Time? Skin Variations

Can the color of a hemangioma vary from deep to light at times?

Three years ago, while taking a shower, I noticed a red spot near the edge of my lower abdomen close to my private area.
When the color is darker, it resembles a shade of wine, and when it's lighter, it turns a pale pink, sometimes fading to the point where it's barely visible.
This pattern of changing colors occurs every month.
I previously consulted a dermatologist who diagnosed it as a hemangioma.
I would like to know if the color of a hemangioma can change like this.

Yes, because microvessels constrict or dilate in response to changes in body temperature and emotional fluctuations.

More Info

Hemangiomas are benign tumors made up of blood vessels, and they can indeed change color over time. This phenomenon is primarily due to the dynamic nature of the blood vessels within the hemangioma, which can constrict or dilate in response to various factors such as temperature, emotional state, and even physical activity. When the blood vessels dilate, the hemangioma may appear darker, resembling a deep wine color, while constriction can lead to a lighter, pinkish hue.
In your case, the color changes you observe—from a deep red or wine color to a lighter pink—are consistent with the behavior of hemangiomas. This fluctuation can happen regularly, as you mentioned, and is not uncommon. The underlying mechanism involves the flow of blood through the vessels; increased blood flow can lead to a more pronounced color, while reduced flow can result in a paler appearance.
It's also important to note that hemangiomas can undergo a natural process of involution, where they gradually shrink and fade over time. This process can take several months to years, and during this time, the color may continue to change. In many cases, hemangiomas will eventually become less noticeable, often resolving completely without any treatment.
However, while color changes in hemangiomas are typically benign, it is crucial to monitor any changes in size, shape, or symptoms such as pain or bleeding. If you notice any concerning changes, it is advisable to consult a dermatologist or healthcare provider for further evaluation. They may recommend imaging studies or a biopsy if there is any suspicion of atypical behavior.

In summary, the color changes you are experiencing with your hemangioma are normal and can be attributed to the vascular nature of the lesion. Regular monitoring is key, and if any new symptoms arise, seeking medical advice is always a prudent approach.

I cannot confirm whether it is a hemangioma because I have not seen the actual lesion. Therefore, I am also unable to respond to whether it will undergo any changes.
