Do angiomas sometimes not blanch when pressed on?

Angiomas: Angiomas are benign lesions composed of dilated tiny blood vessels(capillaries) and most turn white or blanch when pressed. However, cherry angiomas don't blanch. A dermatologist can evaluate and validate the diagnosis if you have concerns.

Yes: Angiomas are caused by an overgrowth of tiny blood vessels called capillaries. The most common angioma is a cherry angioma (also called senile angioma or Campbell de Morgan spots) that usually looks like a tiny bright red mole but can be other colors. Cherry angiomas usually don't blanch when pressure is applied which helps distinguish them from spider angiomas that do blanch with pressure.
