Abstract: There is some controversy about the prevalence of onychomycosis in patients with psoriasis compared to non-psoriatics. We therefore measured the prevalence of toenail onychomycosis in psoriatics and non-psoriatics attending dermatologists' offices. None of the patients had a referring diagnosis of onychomycosis. The prevalence of pedal onychomycosis in psoriatics (n = 561) was 13%. The odds of patients with psoriasis having onychomycosis was 56% greater than non-psoriatics of the same age and sex (P = 0.02).

“…Previous studies reported a prevalence rate of onychomycosis to be 4.6-30% in patients with psoriatic nail disease. [3][4][5][6][7][8][9][10][11][12][13][14] In the present survey, we found nail fungal infection in 47.91% of psoriatic patients with nail psoriasis. This figure is slightly higher than that reported in many other studies, and this could be because of the features of study population (majority of the patients were farmers, housewives and in other occupations involving manual work which may independently increase the risk of onychomycosis).…”

“…Onychomycosis, an infection of the nail unit by dermatophytic as well as non-dermatophytic fungi, has been found to be associated with psoriatic nail changes in several studies. [3][4][5][6][7][8][9][10][11][12][13][14] Psoriatic nail disease may be a predisposing condition for secondary invasion by the fungi. Many psoriatic patients have nail changes which morphologically resemble onychomycosis, and in such patients further differential diagnostic procedures are essential to exclude the presence of coexisting fungal infection.…”

“…Nail psoriasis is usually accompanied, and therefore potentially identifiable, by classical psoriatic scaly plaques on the skin. However, around 27% of dystrophic toenails in patients with psoriasis contain fungus 9. Other differential diagnoses include lichen planus, onychogryposis (thickened nails), trauma, squamous cell carcinoma and malignant melanoma 8…”

“…The main changes are pitting, oil drop discoloration, red spotted lunula, splinter hemorrhages, subungual hyperkeratosis and onycholysis [7,14]. Onychomycosis is the main differential diagnosis and may coexist in up to 30% of these patients [15,16]. It is believed that the structural alterations caused by the inflammation at the nail matrix may facilitate fungal infection [17,18].…”
