Subcutaneous phaeohyphomycosis due to Pyrenochaeta romeroi in a patient with leprosy.

Sir, Opportunistic subcutaneous fungus infections are currently increasing in incidence, partly due to the growing number of patients receiving immunosuppressive therapies. Accordingly, these infections, formerly mostly encountered in hot and dry areas, are now more widely distributed and may challenge clinical and biological diagnosis when occurring in areas where physicians are not accustomed to them. We report on the first case of non-mycetoma deep cutaneous infection due to Pyrenochaeta romeroi, a rarely isolated agent only reported in mycetomas to date, in an immunocompromised patient originating from western Africa.
