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 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
• Cutaneous Anthrax

Histopathologically, mucormycosis may resemble:

• Pancreatic panniculitis
• Gouty panniculitis
