red patch on my foot

Hi, I have a quick question, hope someone can help me: I have a reddish patch on my foot,right where I tie my shoes, that blanches with pressure. Is it true that if it blanches with pressure it is vascular? Or is it possible to be a pigmented lesion(like melanoma?)

Thank you

Hi,
Lesions that blanch are usually due to vascular anomalies. Moles are pigmented spots in the skin which will not blanch.
Moles are flat or elevated, flesh coloured to dark-brown markings located randomly over the entire skin surface. Moles are a clump of cells with different pigment (colour) than the surrounding skin.

The colour of moles varies from flesh-coloured to dark. Moles do not indicate any type of disease or illness and can be removed by a number of surgical techniques if desired.
If the patch on your leg is not bothering you in any way it is best left alone.
