Hyalohyphomycosis by Paecilomyces lilacinus in a renal transplant patient and a review of human Paecilomyces species infections.
A case of hyalohyphomycosis caused by Paecilomyces lilacinus is described in a renal transplant patient. Infection was localized on the left forearm. Two separate cultures of the lesions yielded the same organism. Histological sections disclosed hyaline elements in the tissue. The infection responded well to therapy with oral griseofulvin (500 mg daily) and the patient was cured within 45 days. Forty-six cases of human infection due to Paecilomyces species have been reported previously in the literature, most of them occurring in conjunction with prosthesis implants or immunosuppression. The antifungal sensitivity of Paecilomyces varies widely among the species but the general trend is for Paecilomyces variotii isolates to be almost universally sensitive to amphotericin B and 5-fluorocytosine, while P. lilacinus and Paecilomyces marquandii isolates are resistant to these antifungals but sensitive to the imidazoles.
