Question: 21/Male discoloration of skin around neck/collar bone region

 oisa - Wed May 02, 2007 1:14 am

I am a 21 year old male in good health to my knowledge. I am caucasion but of darker complexion since one of my distant father's side ancestors was african. recently I have noticed a discoloration of the skin at the base of my neck and collar bone region.

My chest is much lighter than my neck as i do not tan at all.
The coloration does not simply fade, it is blotchy and irregular.

Could this be the result of pigmentation differences? A lack of sun exposure to my chest? Or perhaps something more serious?

Any advice would be greatly appreciated.

User avatar There are many possible causes of pigmentation change in the skin, especially on the neck. It may be an issue of differences in sun exposure or possibly a skin condition such as pityriasis alba (essentially very mild eczema) that causes lightening of skin patches. It may also be a condition known as acanthosis nigricans that causes darkening of the skin, especially on the neck.

Generally, the cause is easily diagnosed by direct examination. I would recommend you see your doctor to be evaluated.

Best wishes.
