<human>: My 4 year old has two weird rashes on her legs that at first were itchy one had a blister that popped an the other looked kinda like a horseshoe. Its been a week they arent really bothering her however that are not getting smaller, they just keep getting darker in color. What could this be?
<bot>: Hello, Thanks for the query, You son might have developed fungal infection. Your description matches with that. Usually fungal infections are itchy and recurrent. Please get a KOH mount done, This can confirm the fungal etiology. Treatment can be with oral antifungals as well as with topical antifungals. Treatment must be continued for at least a month to prevent recurrence. Please meet a dermatologist for exact diagnosis. Let me know if you have any other doubt. You can ask a direct question to me on this forum, following the below link.https://urldefense.com/v3/__http://www.ChatDoctor .com/doctors/ Chat Doctor. Thank you
