Phaeoacremonium parasiticum subcutaneous infection in a kidney-transplanted patient successfully treated by surgery

Human infection caused by Phaeoacremonium parasiticum is increasingly being reported. However, only a few case reports show its role as a soil-related contaminant of kidney recipients. We report here a case of a subcutaneous infection by P. parasiticum in a transplanted man. After 4 years, he reported a nonpainful nodule on his forefinger. It was surgically excised. Histological examination revealed dense fibrous connective tissue showing an extensive granulomatous reaction, including the presence of a wooden sliver, and hyaline, branched, and septate hyphae. Six months later, the patient relapsed and underwent large excision. Culture was positive for P. parasiticum. No antifungal drug was administered. Surgical excision was successful.
