We aim to investigate the actual frequency of onychomycosis in psoriatic patients and to compare it between psoriatic and non\u2010psoriatic patients. This retrospective study included a total of 9281 patients, referring to our Mycology Laboratory from September 2003 to May 2018. The patients are divided into two groups: PsoGroup (patients with psoriasis) and non\u2010PsoGroup (non\u2010psoriatic patient). Direct microscopic examination with 20% <jats:styled-content style=\"fixed-case\">KOH<\/jats:styled-content> and culture was carried out in both groups. In PsoGroup (711 patients, 59.50% female, 40.50% male, median age of 52.22\u00a0\u00b1\u00a015.01), the prevalence of onychomycosis was 49.08%. On the other hand, in non\u2010PsoGroup (8570 patients (71.65% female, 28.35% male, median age of 48.51\u00a0\u00b1\u00a019.31\u00a0years), the prevalence of onychomycosis was 51.30%. There was no statistically significant difference between the prevalence of onychomycosis in PsoGroup 49.08% (349\/711) compared to 51.30% (4397\/8570) of non\u2010PsoGroup (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.2578). However, yeasts were significantly more prevalent in non\u2010psoriatic than in psoriatic patients (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.0144.). In our Mycological Laboratory, we observed a similar prevalence of onychomycosis in psoriatic patients and non\u2010psoriatic patients. However, the spectrum of fungal species isolated was different from each other, with a higher prevalence of yeasts in non\u2010PsoGroup that reflect a recent oriental
