Malignant otitis externa is also referred to as skull base osteomyelitis. Pseudomonas aeruginosa is the most common offending pathogen. However, fungal origin is not uncommon. 80-year-old patient having persistent left earache since two months despite adequate treatment. Otologic examination showed signs of inflammation in the auricular pavilion, ear canal stenosis with granulomas and purulent otorrhea. CT scan showed a filled otomastoid, extensive inflammatory process affecting the pre-auricular and retro-auricular tissues and lysis of the tympanic bulla. Given the lack of improvement, mycological examination was performed which revealed the presence of Candida Albicans. Cases of malignant otitis externa caused by Candida albicans are rarely reported. Fungal origin should be suspected in patients who have negative bacteriological samples and no improvement despite adequate antibiotic treatment. It should be confirmed by sometimes multiple mycological samples. Malignant otitis externa caused by Candida albicans is a rare potentially mortal infection.

External auditory canal cholesteatoma is defined as an accumulation of keratin leading to osteolytic bony erosion. It is a rare or underdiagnosed otologic entity. Our study aims to illustrate one case of external auditory canal cholesteatoma. Hypertensive diabetic patient, 65 years of age, under therapy suffering from severe right earache, insomnia, hearing loss, small purulent otorrhea and right facial paralysis grade V since 3 months. Initially the diagnosis was malignant external otitis. The patient underwent antibiotic therapy without improvement. Otologic examination showed burgeoning ulcerative lesion of the posterior wall of the right external auditory meatus. Systematic lesion biopsy was performed and confirmed the diagnosis of cholesteatoma. The patient underwent open technique tympanoplasty. External auditory canal cholesteatoma is rare, clinical symptoms are not specific, coronal CT scan makes a major contribution to a positive diagnosis showing bony crater of external auditory meatus. Treatment depends on the extent of the lesions. It can be based on simple local cares or on open technique tympanoplasty. External auditory canal cholesteatoma may have multiple clinical aspects and lend to confusion with other pathologies of the external auditory meatus.
