“…In the study of Hammerius et al (6), involving 239 psoriatic patients, the prevalence of onychomycosis was identical with that in the normal population. Staberg et al (7) and Larsen et al (8) encountered a higher prevalence of onychomycosis in psoriatic patients compared with patients with other skin diseases.…”

Published data on the prevalence of onychomycosis in psoriasis patients compared with healthy controls are controversial, We therefore conducted a prospective study of toenail onychomycosis, among 113 psoriatic and 106 healthy non-psoriatic subjects, selected from the normal population in the Jerusalem area in the period 2003-05. The results revealed a prevalence of 47.6% toenail onychomycosis among psoriatic patients, compared with 28.4% in normal controls (p=0.0054). Both gender and age affected the prevalence of onychomycosis in both psoriatic and healthy controls, with a higher prevalence in male and elderly subjects. The type and duration of psoriasis were also found to have an impact on the prevalence of onychomycosis. However, the body area involved did not affect the prevalence of onychomycosis in psoriatic patients. Approximately the same percentages of dermatophytes and yeasts were found in psoriatic patients as in healthy controls. However, a higher percentage of moulds was found in psoriatic patients.

Background: Interdigital psoriasis (IP) of the feet is often missed and is commonly mistaken for interdigital fungal infection. Objective: To assess the characteristics and the clinical presentation of IP, in order to better understand if IP should be considered a distinct form of psoriasis or not. Methods: We performed a 1-year observational study on 164 psoriatic patients, affected by moderate to severe cutaneous psoriasis and undergoing systemic therapy, examining each patient between the digits of both feet. In every suspected case of IP, differential diagnosis with interdigital fungal infection was excluded by direct microscopic examination of skin scrapings, by culture and by skin biopsy. Results: We suspected IP in 7 of the 164 patients. IP was confirmed in 6 patients and in the other one a diagnosis of tinea pedis was made. Conclusion: IP proved to be not rare or atypical since IP localized between the toes usually presents as characteristic whitish and sodden plaques or patches. Such a diagnosis should be considered in all patients presenting characteristic lesions especially if these have a negative fungal culture, are resistant to antimycotic treatment and involve patients with a history of psoriasis.

“…This phenomenon could be explained by the fact that, generally, both disorders are more common among men. [7][8][9]11,[16][17][18] The coincidence of tinea pedis and toenail onychomycosis also increased with age, and it is estimated that 25.7% of elderly individuals have both types of infections. 17 Older patients have demonstrated sig- *Unless otherwise indicated, data are reported as number (percentage) of subjects.…”
