RESUMO
Mucormycosis is a rare opportunistic infection caused by Mucorales fungi. Cutaneous mucormycosis typically present as chronic indolent infection, whereas rhino-orbital mucormycosis is rapidly progressive disease often invade the adjacent cerebral tissue associated with high mortality. This case represents the atypical clinical history of rhino-orbital-cutaneous mucormycosis. The patient was presented with a right orbital cellulitis associated with an extensive multiple suppurative deep cutaneous infection and worsening headache. The skin lesion was initiated from a localized abscess at the right periorbital area nine months before admission. Suspicion of fungal infection was raised after weeks of non-responsive antibiotics treatment. Aggressive treatment with exoneration of the right eye and surgical debridement was undertaken. Periodic acid Schiff staining from healthy periorbital tissue revealed ribbon-like hyphae with pauciseptate and 90° branching identified as Mucoraceaefamily. The resolution was seen after four weeks of antifungal treatment with Amphotericin B.
