Hello,

Thanks for sharing your query with us.

Asian skin is prone to pigmentation. Some of the common causes of pigmentation in the area you mention may be:
1) Macular amyloidosis
2) Acanthosis Nigricans
3) Post inflammatory pigmentation
4) Melasma

There are other causes like lichenplanus pigmentosus etc which should be ruled out

I will be able to help you better if you can send a few pictures in good resolution. You can send them to

with subject as “ Attention : Dr Tanushree Biswas”

Best wishes,

Hello,
Thanks for following up.

I have seen the pictures you sent. From the pictures, I would put the diagnosis more in favor of Macular Amyloidosis.

Macular amyloidosis is a skin condition characterized by itchy, brown, rippled patches of pigmented skin in the body. Here there is a deposition of an abnormal extracellular family of proteins.

The cause of this is unknown. However certain things like scratching, rubbing, and all forms of friction increases this pigmentation severity.

The diagnosis is confirmed by a skin biopsy.

Treatment includes potent topical corticosteroids and systemic antihistamines. There are other office based treatment modalities like lasers, UV-B light which helps in this case.

You may visit a dermatologist and confirm the diagnosis by undergoing a skin biopsy. Take adequate sun protection and avoid any friction (like with towels, tight clothing, belts etc) to prevent this from increasing.

Hope this is helpful. I will be happy to assist you further if required.
Best wishes,
DR.TANUSHREE BISWAS

okay, but these spots are not itchy at all, so could it still be Macular amyloidosis? Could it also be a fungal infection caused by sweat?

Hello,

Thanks for the follow up.

It is not necessary that Macular Amyloidosis is always itchy. So, it still could be Macular Amyloidosis.

I don't think it is a fungal infection. It is uncommon for a fungal infection to have similar presentation.
