Hi,
Thanks for writing to us.
The description provided is too brief to think of a particular diagnosis.
It could be a rash due to injury, fungal infection( tinea or p versicolor), pityriasis rosea, post inflammatory hyperpigmentation, psoriasis etc.

I would like to know if
It is flat or elevated
If it is covered with scales
Type of lesion- ring shaped, bumpy , margins etc
If the sensation in the lesion is intact ie you can feel touch, pain temperature in thr lesion
Any preceding injury or exacerbating factor
Blanchable or nonblanchable lesion

I would also request you to attach an image of the concerned lesion as it would help me in reaching a probable diagnosis.

Hoping to hear from you soon.

Hi,
Thanks for answering the queries.
From the description provided, I can think of few possibilities
Tinea corporis- fungal infection characterised by ring shaped lesions. Initially may begin as small round dot that spreads and assumes a ring shape. May be slightly scaly. Treatment is antifungal cream like terbinafine, clotrimazole, miconazole etc

Psoriasis- red elevated rash with thick scales, usually round shaped or may have irregular geographic borders. Sometimes can be ring shaped. Treatment is emollient and steroids

P rosea characterised by a mild scaly red rash. Scaling present at margin of the lesion. Self resolving. No treatment as such required however calamine and steroid may help.

Granuloma annulare- symptomless lesion. Multiple papules( bumps) coalesce to form a ring shaped lesion. Treatment steroid, tacrolimus etc.

Kindly send me an image of the lesion as dermatology is a visual field and a probable diagnosis can only be ascertained by having a look at the lesions.

Hoping to hear from you soon.
Take care
