A distinct clinicopathological presentation of cutaneous dermatophytosis mimicking autoimmune blistering disorder

Abstract

Infectious diseases can clinically present as vesiculobullous disorders. Direct immunofluorescence (DIF) study of skin biopsy helps distinguish true autoimmune blistering disorders from other conditions. In many situations, even DIF findings in infections disorders imitate autoimmune process. Here, we describe a case of 29-year-old female with extensive dermatophytosis having presentation mimicking bullous pemphigoid both clinically and histopathologically including DIF findings.
