An eczematous reaction in a pattern corresponding to an allergen, which is intensely pruritic and may have vesicles, unlike the annular shape of tinea.
Presents as a persistent, solitary, erythematous, scaly plaque (carcinoma in situ), which does not respond to antifungals.
An infection favoring moist, intertriginous areas, characterized by beefy-red erythema and classic satellite pustules.
Distinguished by its distribution, which conforms to the area of contact with an irritant or allergen.
Presents as intensely pruritic, coin-shaped, weeping, or crusted plaques without the central clearing seen in tinea.
Causes atrophic, scarred plaques with follicular plugging, a different morphology than the active border of tinea.
A bacterial infection in skin folds that appears as a brown or pink patch and fluoresces a classic coral-red under a Wood's lamp.
Simple inflammation of skin folds from friction and moisture, which lacks the scaly, active border of tinea.
An eczematous reaction caused by a chemical or physical irritant, lacking the annular shape and positive KOH prep of tinea.
Affects the weight-bearing surfaces of the feet in children, causing a glazed, shiny erythema with fissuring, sparing the web spaces.
A unilateral, eczematous-appearing plaque on the nipple or genital region, which is an underlying adenocarcinoma.
A bacterial infection of the soles causing shallow pits and a foul odor, not the scaling or inflammation of tinea pedis.
Can be annular, but is characterized by a deeper red color and a silvery scale, with a negative KOH prep.
