Overview
Mucormycosis can be difficult to diagnose and a high degree of clinical suspicion is required. Mucormycosis should be differentiated from diseases like invasive aspergillosis, orbital cellulitis, extra nodal T cell lymphoma and cutaneous anthrax. Patient history is an important part of the diagnosis and aids in ruling out other differentials. Other features which help differentiate conditions with similar presentations are radiological and histopathological appearance.
Differential diagnosis
Mucormycosis must be differentiated from other conditions with similar presentation. Invasive fungal disease should be considered in any immunocompromised patient presenting with a new cranial neuropathy or ocular motility abnormality[1] for example, invasive aspergillosis. Other differential diagnoses which may involve progressive facial swelling, ulceration and destruction and resemble mucormycosis include orbital cellulitis, extra nodal T cell lymphoma and cutaneous anthrax. Histopathologically mucormycosis may resemble pancreatic and gouty panniculitis.
