title: Proximal white subungual onychomycosis caused by Microsporum canis in systemic lupus erythematosus.
abstract: We report the case of a Mexican lupus patient who developed proximal white subungual onychomycosis on multiple toenails. Microsporum canis was the causative agent. Both nail invasion by M. canis and proximal white subungual onychomycosis are rare conditions indicative of an underlying immunodeficiency.
