Prominent papillary dermal edema in dermatophytosis (tinea corporis)^*

Abstract

Our case series serves as a reminder that dermatophytosis should be strongly considered in the differential diagnosis of lesions with PPDE. Fungal culture may be helpful in patients whose biopsies show PPDE, negative periodic acid-Schiff (PAS) stains and who fail to respond to conventional anti-inflammatory therapy. This study lends support for the routine use of PAS stains in biopsies of inflammatory dermatoses.
