Are the brown patches on the neck due to dead skin?

Hello doctor,

I have brown patches all around my neck and on my chest. On closer inspection these patches are actually made up of small brown or black spots. On my chest, they feel rough and have a matt texture. On my neck they are pretty much noticeably raised from the skin surface if I feel it with my hand.

After a bath, if I rub them with my hand very thoroughly or if I scratch them with my nails when wet, they come off pretty much like dead skin. There are loads of skins that I shed when I do that. It does get lighter and much less noticeable, but never gets removed. They grow back in just two to three days. I have had this issue for more than two years now. I tried taking antifungals and applied Fluconazole cream for a week, but nothing seemed to help. I have been to quite a few dermatologists who seemed to have different opinions. I read it could be pityriasis versicolor. Please help me.

Thanks.

Hello doctor,

Thank you for the reply.

No, there is no pain or itching. I have taken antifungals both topical and oral, but it did not help.

Thanks.
