We report a case of a 71-year-old male who developed severe cellulitis of his right forearm and hand after he had an accidental injury from the sharp edge of a metal plate of a birdhouse. The patient suffers from chronic asthma and has been treated with systemic corticosteroids for years. Culture of aspirates from two sites of the wound area revealed growth of Cryptococcus neoformans in one and Acinetobacter lwoffii in the other. After combined treatment including antibiotics, antifungal therapy with fluconazole 400 mg/d and surgical debridement followed by a mesh graft, the patient achieved complete healing of the wound. Five months after the infection, the patient was still positive for cryptococcal antigen at a titer of 1:64 despite oral treatment with fluconazole 50 mg/d, and maintenance therapy with fluconazole 200 mg/d was recommended for 6 months, or longer depending on further results. The clinical and microbiological characteristics of this patient as well as therapeutical and epidemiological aspects of primary cutaneous cryptococcosis (PCC) are discussed.
