Case report: cutaneous penicilliosis due to Penicillium chrysogenum.

A case of cutaneous penicilliosis in a young man, without immunological compromise is reported. The lesions in the neck were characterized by two exudative reddish-purple pruriginous and painless spots. Penicilliosis was diagnosed after serial laboratory studies based on the observation of hyphae by direct microscopic examination and histopathology. Cultures of the tissue obtained from the lesions, developed mould colonies with typical conidia of Penicillium chrysogenum, which was thermotolerant at 37 degrees C. The treatment with itraconazole was successful, and 15 days after cessation of therapy, no recurrence of infection was observed. The epidemiology of this type of mycosis is commented upon, as well as the rarity of infections produced by Penicillium, even as opportunistic pathogens. The isolation of P. chrysogenum from skin lesions is exceptional.
