Paecilomyces lilacinus infection in a liver transplant patient: case report and review of the literature.
A 56-year-old male who was 12 months status post liver transplant presented with a 2-month history of painful, erythematous nodules over the right knee. Several biopsies yielded a mold initially phenotypically identified as a Penicillium species, but molecular sequence analysis ultimately determined the identity as Paecilomyces lilacinus. Several courses of oral voriconazole were required for resolution of the infection. A review of the literature revealed that Paecilomyces species are an infrequent cause of disease in transplant patients, with skin and soft tissue infections being the most common presentation. It is important to accurately identify these infections, and polymerase chain reaction assay using universal fungal primers offers a rapid and precise diagnostic approach. Treatment of Paecilomyces infections may require multiple courses of antifungal therapy, often with surgical debridement. We suggest that voriconazole may be a useful treatment alternative to the more traditional therapy with amphotericin B-based agents.
