Background :
@EN Nail involvement in psoriasis is common. But their manifestions may often be difficult to differntiate clinically from onychomycosis, and results on fungal infections in psoriatic nails are still conflicting.
@ES Objective :
@EN The purpose of this study was to observe the clinical signs and mycolgical profiles of psoriatic nails.
@ES Methods :
@EN The frequency and types of clinical signs were observed prospectively according to sex, age, site, and accompaning tinea pedis. Repeated direct micrscopic and culture examinations, and KONCPA(KOH+Nail Clipping+PAS) study were done in the
nails
showing subungual keratosis, and/or onycholysis.
@ES Results :
@EN Fifty nine(59%) out of 100 patients with psoriasis had psoriatic nail changes. Nail changes were more common in fingers than in toes(55% vs 34%), in males than in females(68.9% vs 43.6%). The types of frequent nail changes were isolated in 2
cases(8%) and yeasts and non-dermatophytic moulds were isolated in 20-40% of psoriatic nails.
@ES Conclusion :
@EN Psoriatic nail changes of dermatophytes in the psoriatic patients were not so rare. Repeated culture was thought to be the most valuable test because yeasts and moulds were frequently isolated as saprophytes or contaminants. (Kor J Dermatol
