Abstract
Onychomycosis is a fungal infection of nails caused by dermatophytes, yeasts or
nondermatophyte molds and one of the most common nail diseases seen in dermatology (1).
Onychomycosis clinically presents with nail discoloration which could be yellow, white or,
brown, detachment of the distal nail plate from the nail bed, easy fragility, nail plate thickening,
and subungual hyperkeratosis (2). To arrive on accurate diagnosis of onychomycosis,
mycological laboratory testing and confirmation is the optimal way and it is cost effective for the
patient than treating the patient without confirming the diagnosis (3). Even though we usually
use potassium hydroxide mount (KOH) as a diagnostic test for clinically suspected
onychomycosis cases in our setting, the few studies done in Ethiopia gave emphasis on
identification of the etiologic agents by culture.
