Aspergillus niger, an opportunistic filamentous fungus, was

identified as the cause of chronic bilateral otomycosis in a 46-year-

old female patient who was unresponsive to different drugs. The

patient showed signs of erythema, otalgia, itching, otorrhoea and

presence of greyish black coloured mass in both the ear canals. The

direct microscopical examination of the ear debris in potassium

hydroxide preparations, Giemsa, phase contrast and Gram revealed

many thin, branched septate hyphae, condia and conidiophores

morphologically indistinguishable from Aspergillus spp. The

histopathological section of the ear wax mass by haematoxylin and

eosin and periodic acid-Schiff techniques also showed similar fungal

elements. The patient responded to 1% solution of mercurochrome. The

use of mercurochrome in developing countries like India may be

recommended to treat the fungal otitis in patients. We also

emphasize that \'Narayan\' stain should be routinely employed by

microbiology and public health laboratories to study the morphology

of pathogenic fungi.
