Black across forehead.

[trixie_m]

A friend of mine has a big black spot going all the away across their forehead. They did years ago go to a regular medical doctor that told them it was a yeast infection. But here it is years later and the spot seems to be getting bigger almost the size of their whole forehead. Was wondering if you knew what this could be from?

Hi,

Is this black spot really black or simply a dark brownish color?

Is this associated with any itchiness, scaling or pain?

Any associated prolonged exposure to the sun or to any chemicals?

Does your friend have any known allergies?

Any other discolorations or pigmentations in other parts of the body?

In reference to black spot on forehead, it appears to only be black. It has no pain doesn't look scalley. They do work outside all day and they are around chemicals from the car washes that you drive thru. They are allergic to penicillin. This appears to only be the spot on the body that is black. It is all the way across the forehead they clean it daily with the wipes you buy for your face scrub it hard daily.
