Dermatophytosis of nail
Dermatofitose da unha
CategoryDefinition
Fungal infection of the nail plate due to dermatophyte fungi (tinea unguium). Chronic infection of toenails is very common and is frequently associated with dermatophytosis of the interdigital clefts and/or sole of the foot. Dermatophytosis of the fingernails is much less common. Infection results in a range of clinical signs including white or yellow discolouration, detachment of the plate from the nail bed (onycholysis), keratinous thickening under the nail plate (subungual hyperkeratosis) and fragility and fragmentation of the abnormal nail plate.
