Rash on inside of legs

[budasolkai]

I have had this for a while and it is slowly spreading. It started off as a small spot and has spread to both legs and my groin and butt. Please help me identify it and possibly treat it. It does not hurt, itch, burn or cause any sort of discomfort.

Hello,
It looks like erythrasma skin. It is true that groins are effected but the typical appearance is well-demarcated, brown-red macular patches. The skin has a wrinkled appearance with fine scales.

It has to be differentiated from contact dermatitis,psoriasis,sweat dermatitis and fungal infections which may mimic it.Wood lamp examination and gram staining are the tests for its diagnosis.

So nothing can be confirmed without examination.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

'Erythrasma'. Clotrimazole creme helps.
