Mucormycosis Presenting as Orbital Cellulitis; A Case Report

Mucormycosis is a rare invasive fungal infection caused by fungi from the Mucorales order [1]. Mucormycosis is classified according to anatomical site of infection [2] with rhino-orbitalcerebral is the most common [3]. This fungal infection begins from the sinonasal mucosa after inhalation of fungal spores and the aggressive and rapid progression of the disease may lead to orbital and brain involvement [4]. Predisposing factors for mucormycosis include diabetes mellitus [3], systemic immunosuppression [5] (especially in patients with haematological malignancies [6]) and iron overload [7]. Mortality rates associated with mucormycosis vary depending on the site of infection and the initial health of the patient but have been reported to range between 40 and 70% [8].
