Painless rash in a transplant patient

Dermatophytes are common keratinophilic fungi responsible for superficial skin infections. Deep dermatophytosis is a rare form of invasive skin infection described in immunocompromised patients. We report the case of a 65‐year‐old man with a history of an orthotopic liver transplant for hepatocarcinoma 6 months earlier, who presented with small painless erythematous papules in lower limbs, some of which were umbilicated. Skin biopsy showed an intense non‐necrotizing granulomatous reaction in the dermis around fungal structures. Trichophyton rubrum was identified as the causal agent through culture and internal transcribed spacer sequencing.
