Hi
Yes, a ringworm or a fungal infection may be a differential here. The darkening may be secondary to scratching or irritation in the area. Ringworm which is actually a fungal infection have preference over these areas, as the groin is usually covered and moist. This may encourage growth and colonization of these organisms.
I know you are worried about this. I suggest that you have this assessed by a dermatologist as this may need topical medications.
No blisters. No pain. Could it be ringworm?
Hi.
A darkening discoloration with itchiness may be due to a dermatitis or a fungal infection. These skin conditions are characterized by itchiness. I suggest that you have this assessed by his dermatologist. The darkening may be secondary to the frequent scratching in the area as well as the friction caused by the contact of the skin of both thighs. It is best to have your doctor assess this as this may need topical medications.
Are there any blisters in the area?
Any redess or pain?
