Otomycosis is defined as a fungal infection that usually affects the external ear canal (Ali et al., 2018). In rare cases, it may also involve the middle ear, provided that the eardrum is perforated (Righetti, Dall’Asta, and Hajslova, 2016). Primary otomycosis occurs in the external auditory canal in an immunocompetent individual, while secondary otomycosis is present in the middle ear alongside the history of existing otitis externa, trauma or postoperative ears. Patients can be immunocompromised or healthy (Prasad et al., 2014). Common causative agents of this disease are A. fumigatus, A. flavus, A. niger and Candida spp., with A. niger being the most prevalent (Prasad et al., 2014). Otomycosis can be characterized by inflammation, scaling, itching, pain, feeling of blocked ears, tinnitus, deafness and otoscopy revealing masses of hyphae, spores or curd-like gray/white discharge (Anwar and Gohar, 2014).
Otitis Externa
Published in Firza Alexander Gronthoud, Practical Clinical Microbiology and Infectious Diseases, 2020
Otitis externa usually develops within a few weeks. The main feature is rapid onset of signs or symptoms of inflammation of the external ear canal including otalgia, itching, or fullness with or without hearing loss and ear canal pain on chewing. A hallmark sign of diffuse AOE is intense tenderness of the tragus when pushed and/or tenderness of the pinna when pulled, disproportionate to what might be expected based on appearance of the ear canal. Otoscopy can reveal diffuse ear canal oedema, erythema, otorrhea or debris in the ear canal. Regional lymphadenitis or cellulitis of the pinna and adjacent skin may be present in some patients. Most common pathogens are Pseudomonas aeruginosa and Staphylococcus aureus. Otomycosis or fungal otitis externa caused by Aspergillus niger or Candida spp. is less common but may be more common in chronic otitis externa or after antibacterial treatment.

Fungal external otitis or otomycosis, is usually associated with complains of ear pruritus and mild to moderate otalgia. Physical examination can help in etiological agent identification. While Candida infection is usually associated with whitish residue, which occludes EAC with superficial conidia and resembles cotton; some Aspergillus species are associated with whitish residue, dotted with superficial black conidia, which reminds wet newsprint [1].

Otomycosis result from the action of certain fungi found on the epithelium of the external auditory canal. The tympanic membrane and the middle ear space are rarely involved [4,5]. Species from genera Aspergillus and Candida are the ones most often involved to cause otomycosis. These fungi bearing varied pathogenicity are opportunistic and part of the normal microbiota from different body parts [6].
