Auricular mucormycosis complicated by parotid abscess and facial paralysis: A very rare case report.

Mucormycosis is a serious and relatively rare invasive fungal infection. The rhino-orbito-cerebral localization is the most frequent. Other localizations have been reported including: cutaneous, pulmonary, disseminated, gastrointestinal, and miscellaneous. Mucormycosis of external ear with facial palsy is extremely rare and only few cases have been reported in the literature. We describe a case of mucormycosis of the external and middle in a 44-years-old diabetic patient which had a very aggressive form of necrotic infection of the ear auricle complicated by parotid abscess, facial, and vagal nerve paralysis. Auricular mucormycosis was suspected and the diagnosis was established after biopsy and histological examination. The patient was treated immediately with intravenous amphotericin B followed by extensive surgical debridement of the necrotic lesions. The patient responded well to the treatment despite the persistence of facial palsy.
