Hello. Thank you for writing to us
I suggest a possibility of either
Tinea faciei Or a Polymorphic light eruption/ PMLE..
Fungal infections have a typical morphology i.e peripheral expanding, raised, red and scaly rim and central clearing.
The ring may be partial or complete.
PMLE may present as an eruption of red bumps or patches over sun exposed skin. The lesions in PMLE are usually itchy but lack a characteristic ring shaped morphology of fungal infections.
However, it may be difficult to diastinguish tinea from PMLE on clinical examination.
Confirmation of diagnosis would require a clinical examination and may also require a lab test, if doubtful.
KOH wet preparation made by scraping a small amount of scale can be examined under the microscope to look for fungal elements.
Treatment would be guided by the diagnosis.
Fungal infection would require topical antifungals with or without Oral antifungals whereas a light eruption would respond to sun protection along with topical
steroids.
An OTC oral antihistamine e.g
cetrizine 10 mg once daily will provide symptomatic relief from itching.
I suggest that you visit a
dermatologist for a confirmatory diagnosis as well as for the needful.
