“…Las infecciones producidas por Alternaria han sido descritas en pacientes inmunocomprometidos, aunque también se ha observado en pacientes inmunocompetentes 8,17,18 . Según Pastor y Guarro 8 , A. infectoria es la especie más aislada en clínica y el trasplante es el factor de riesgo más frecuente en los casos de alternariosis cutánea y subcutánea.…”

Phaeohyphomycosis caused by Colletotrichum gloeosporioides and Alternaria infectoria in renal transplant recipientSeveral species of black fungi have been reported as agents of subcutaneous phaeohyphomycosis. Although most of these fungi are considered opportunistic pathogens, they play an important role in phaeohyphomycosis, a disease considered an emergent mycosis among solid organ recipients. We report a case of phaeohyphomycosis caused by Alternaria infectoria of the left hand and the 4 th finger of the right hand of a 68-year-old male who underwent a renal transplant 35 months before. The lesion was treated with surgical excision. One year later, the patient presented a new lesion on the 5 th finger of the right hand, but this time caused by Colletotrichum gloeosporioides that was also removed surgically. Both lesions did not relapse after being removed. Antifungal susceptibility testing was performed against five antifungal drugs (amphotericin B, itraconazole, flucytosine, fluconazole and voriconazole). Alternaria infectoria was resistant to all five drugs and C. gloeosporioides was sensitive only to amphotericin B and voriconazole. We emphasize the need of histopathologic and microbiologic studies of new lesions of phaeohyphomycosis, since in this case the same patient was infected twice by two different fungi.

“…Castro y cols. 11 , informaron el quinto caso en un paciente trasplantado renal infectado con C. crassipes y recientemente, C. gloeosporioides fue descrito en un paciente trasplantado de pulmón 17 . Nuestro paciente presentó un cuadro clínico causado por dos hongos dematiáceos distintos.…”
