LAUSR

An 11-year-old immunocompetent girl presented with two and a half months of progressive right orbital cellulitis, which did not respond to multiple courses of antibiotics or prednisone. A panfungal polymerase chain reaction primer was positive for Saksenaea vasiformis, and she completed 5 months of oral posaconazole therapy after debridement. Saksenaea vasiformis is a rare cause of zygomycosis, and it typically causes skin and soft tissue infection in immunocompetent hosts, particularly after a traumatic injury. The diagnosis should be considered in cases with a protracted course that fail to respond to typical antibiotic therapy. Treatment includes surgical debridement, in additional to antifungal therapy with amphotericin B or posaconazole.
