Coincidence of psoriasis and onychomycosis

In a three year period, authors observed 16 cases whith plaque psoriasis accompanied with nail symptoms characteristic for typical psoriasis. Microscopy examinations were positive in cases of 7 in fingernails, and in 3 cases of toe nails. In cultures, pathogenic agents were grown in 4 cases from finger nails, in 2 cases from toe nails. Considering the 16 psoriasis cases out of the 1087 mycotic tests carried out in the 3 years period, onychomycosis occurred only in 1,5% of the cases. Therefore further studies are needed for the assessment of onychomycosis in psoriatic cases.
