Superadded chromomycosis in recessive dystrophic epidermolysis bullosa: An easily misdiagnosed entity

Abstract

Recessive dystrophic epidermolysis bullosa (RDEB) (Hallopeau Siemens) is one of the most severe forms of epidermolysis bullosa (EB) with generalized vesiculation over the skin and mucous membrane resulting in extensive scarring with exuberant granulation tissue. Because of widespread erosions, patients are prone to secondary infection. We are reporting a 10-year-old male child having RDEB who presented with a nonhealing ulcer with verrucous growth over bilateral knees for 2 years which was considered as part of the disease by many dermatologists and was later diagnosed to be superadded chromoblastomycosis based on histopathology. We are highlighting this case to increase awareness among dermatologists regarding the occurrence of superadded deep fungal infections like chromoblastomycosis in patients of RDEB which is usually missed or misdiagnosed as part of the disease.
