Scedosporium Sinusitis: A Rare Opportunistic Infection.

Scedosporium sinusitis is an opportunistic fungal infection that is difficult to treat due to its inherent resistance to many antifungal agents. Infections may cause both localized or disseminated disease usually in skin and soft tissues. Immunocompetent persons are typically unaffected and disseminated disease occurs in immunocompromised hosts. Scedosporiumis a common hyaline mold causing sinopulmonary disease in those with hematologic malignancies and neutropenia. A 38-year-old Caucasian male with a medical history significant for HIV with intermittent treatment compliance, high-grade diffuse large B cell lymphoma (DLBCL) on chemotherapy, and hemophagocytic lymphohistiocytosis (HLH) presented with right-sided facial pain and fever. Maxillofacial computed tomography (CT) showed thickening and opacification of the sphenoid and maxillary sinuses concerning for fungal sinusitis. Endoscopic transsphenoidal debridement showed fungal growth of Scedosporium and the patient's blood cultures were ultimately negative. The patient underwent debridement of fungal sinusitis as well as right medial maxillectomy and ethmoidectomy. A three-month course of voriconazole was started and completed with weekly liver enzyme tests to monitor medication side effects. He has since been observed well as an outpatient with his oncologist after three months loss to follow-up and his infection has resolved.
