Presumed blastomycosis endophthalmitis

A 49-year-old outdoor laborer had an endophthalmitis in one eye and small posterior segment lesions in the other, as well as raised lesions on his skin. The diagnosis of disseminated North American blastomycosis was established by the performance of a biopsy on one of the skin lesions. The ocular inflammation slowly improved with intravenous amphotericin B therapy, and the ocular lesions, presumably caused by Blastomyces dermatitidis, were followed clinically for six months. The patient died of a hospital-acquired pneumonia caused by Staphylococcus aureus.
