Abstract

Purpose: The authors report the clinical, cytologic, and histopathologic findings of a unique presentation of concomitant unilateral endophthalmitis and orbital cellulitis secondary to Blastomyces dermatitidis. Design: Case report. Methods: A 29-year-old healthy woman with a history of pulmonary tuberculosis presented with a painful right eye and rapidly decreasing vision. Fundus examination showed a diffuse elevated choroidal lesion at the posterior pole. With an otherwise unremarkable systemic work-up, the patient was treated with systemic antibiotics and corticosteroids for a presumed diagnosis of choroidal tuberculous granuloma. After an initial response to the treatment, the patient's condition deteriorated rapidly with visual acuity decreasing from 20/25 to no light perception in 3 months. Ipsilateral proptosis developed with magnetic resonance imaging showing a poorly defined orbital mass. Surgical enucleation and an orbital biopsy were performed. Results: Histopathologic examination of the orbital specimen and an intact enucleated globe showed a diffuse necrotizing granulomatous process with the presence of numerous yeasts consistent with B. dermatitidis. This subsequently was confirmed by positive culture of B. dermatitidis from the orbital specimen. Conclusions: This is a unique case of concurrent unilateral endophthalmitis and orbital cellulitis secondary to B. dermatitidis. Intraocular dissemination of blastomycosis should be suspected in the differential diagnosis of endophthalmitis in patients with previous or active pulmonary lesions of equivocal nature. Early diagnosis and prompt treatment with antifungal medications are essential.
