do you have a birthmark?

I don't see any different tones or colours, or any special marks on my body, so I think I cannot find a birthmark. There is only one small patch of darker brown found on my knee which I had a fall in my younger days.

I'm not sure whether I had other birth mark other than the round light brown birthmark behind my back as what I can remember.

i think everybody would have birthmark anywhere on the body. i do have it on my neck. its light brown, i mean lighter then my skin colour and it is clearly visible.

I have many of them. I have one on my neck. Some on my back, arms and legs. I like the ones on my arm.

I have a birthmark on my foot and its light brown. When I was a child I used to wash it so much so it leaves. I didnt use to like it but after a while I got used to it!

I have a couple of them. I have a pigment problem which leaves white lines on my knee up my belly and behing one of my legs. And the leg with the white line has freckels and my other leg does not. It's kinda funny but when I get in the sun those white spots never tan they just become more visible and I have a birth mark on my chest.
