You probably have Acanthosis Nigricans. But I also want to rule out another condition called Lichen Planus Pigmentosus.

With the photos you have sent, it looks like the surface of the discoloured skin is rough and thick as compared to the unaffected skin.

Do anyone else in the family has this problem too? Does someone in the family have diabetes?

I can give better reply if you answer these question also.

Waiting for your replies.

Hello Doctor

I don't know what the problem with my skin.

The surface of the discolored skin is not rough. it is just like normal skin.

No one in my family has this problem and i am not sure that no one has diabetes in my family because my father has expired, my mother not has diabetes and her health is 100% healthy and i am the only son for them.

Thanks for your prompt replies.

You may be having Lichen Planus Pigmentosus.

I suggest you to stop whatever treatment you are taking after discussing with your primary doctor. You may need biopsy of the lesions for confirmation of the diagnosis and to look for the activity of the disease. Further treatment plan depend on the results of the biopsy.

Lichen Planus Pigmentosus is a chronic skin condition where the treatment is long and the improvement may not be 100%. Steroids are usually prescribed initially to arrest disease progression. They also help in lighten the skin colour as well.

Please talk and discuss about it with your dermat and go ahead with skin biopsy if appropriate.

Wish you good health
