Hello, I'm a medical professional with a focus on dermatology. I can help answer your question about hemangiomas.
Hemangiomas are benign tumors composed of blood vessels. They can occur anywhere on the body but are most commonly found on the skin. When it comes to whether hemangiomas blanch, it's important to understand what "blanching" means. Blanching refers to the temporary loss of color in an area due to the constriction of blood vessels, which is often seen when pressure is applied.
Hemangiomas can indeed blanch, especially when they are superficial and the pressure applied is sufficient to cause the blood vessels within the hemangioma to constrict. This is a characteristic feature that can help differentiate them from other types of skin lesions, such as vascular malformations, which typically do not blanch with pressure.
However, not all hemangiomas will blanch to the same degree, and deeper ones may not blanch at all due to the limited effect of pressure on deeper blood vessels.
