BACKGROUND Psoriasis is a common inflammatory skin disease that affects people of every age; prevalence in pediatric population is unknown because of the lack of studies. METHODS We collected data about patients 0-18 years old coming to our center in the period from November 2010 to September 2012. RESULTS We found 69 children (38 males, 31 females) affected by psoriasis, with a male-to-female ratio of 1.2 and a prevalence of 0.75%. Plaque psoriasis was the most common clinical manifestation (72.54%), followed by guttate psoriasis (13%). The most frequent comorbidities were overweight and obesity (26%). Most patients had a mild disease with PASI

Background Despite the better prognosis of melanomas localized on lower extremities, some studies have suggested that melanomas on the foot are related to a poorer survival and should be considered separately. Objective To review our case series of cutaneous melanomas on the lower extremities and to analyze the clinicopathological association, time course, types of progression, and survival differences. Methods We included 1671 patients (stage 0–II) with a cutaneous melanoma on the lower extremities (subungual melanomas were excluded). Of these, 327 were localized on the foot. Multivariate analyses were performed to evaluate disease-specific survival and disease-free interval. Results Distribution of known prognostic factors and patterns of progression of foot and leg melanoma differ across genders. The foot site was confirmed as a negative independent prognostic factor on disease-specific survival and disease-free interval. Conclusion Foot melanoma could represent a particular subgroup, which could require specific management in the future.

Dermatophytosis caused by Trichophyton rubrum is the most common cutaneous fungal infection in industrialized countries and worldwide with high recurrence and lack of treatment response. In addition, patients with cutaneous and concurrent toenail lesions are often misdiagnosed and therefore treated with an inappropriate therapy. In this study, we evaluated five previously misdiagnosed cases of T.rubrum chronic dermatophytosis sustained by two variants at sites distant from the primary lesion. Our patients were successfully treated by systemic and topical therapy, and 1 year after the end of therapy follow-up did not show any recurrence of infection.Our data indicate that the localization of all lesions, the isolation and the identification of the causative fungus are essential to establish the diagnosis and the setting of a correct therapeutic treatment to avoid recurrences.

Objective: To determine the epidemiology and the aetiology of tinea capitis in the elderly in Turin (Italy). Methods: We prospectively collected all cases of adult tinea capitis in the Dermatology Clinic of the University of Turin from January 1997 to December 2012. Results: 13 patients (4 males and 9 females) with a mean age of 56.5 years were found to be affected by tinea capitis among a total number of 508 (2.6%). Diagnosis was made on clinical appearance and mycological examination. Culture identified M. canis in 7 patients (53.8%), T. mentagrophytes in 3 patients (23.1%), T. rubrum in 2 patients (15.4%) and T. violaceum in 1 patient (7.7%). 6 cases reported contact with animals. Treatment consisted in administration of Griseofulvin at the dose of 500 mg/d or Terbinafine at the dose of 250 mg/d for at least 8 weeks. A complete recovery was observed in 10 patients, whereas 3 of them suffered from cicatritial alopecia. Conclusion: This study wants to highlight the importance of considering tinea capitis as a differential diagnosis in elderly patients with scaly scalp lesions, even though it is considered to be rare in adults.

The increased prevalence of dermatomycoses along with the wide range of organisms now recognized as potential pathogens needs accurate laboratory isolation and identification of the aetiological agents. In this report three cases of foot dermatomycoses due to filamentous fungi commonly present in the environment with ubiquitous distribution are described in immunocompetent subjects. Skin and nail samples were collected, suspended in 20% KOH solution, examined under a light microscope and cultured in Mycobiotic agar and Sabouraud dextrose agar containing chloramphenicol to detect fungal growth. Phoma herbarum, Chaetomium globosum, and Microascus cinereus were isolated and identified.

This report documents tinea pedis and tinea unguium in a 7-year-old child. In all cultures Trichophyton rubrum was present. As tinea pedis and tinea unguium affect adults more often than children, they might be overlooked and misdiagnosed in the latter.

There is an increased incidence of the morbidity and mortality associated with fungal infections caused by resistant fungi in various groups of patients; therefore the monitoring of their susceptibility to antifungal agents to be necessary for optimizing clinical therapeutic treatment. The susceptibility profiles of recent clinical yeasts and yeast-like fungi isolated from Turin’s Hospitals to current antifungal drugs are here reported. Candida albicans was the most frequently isolated species (40%), followed by C. glabrata (22%).A high rate of susceptibility to all antifungal agents tested was observed and low evidence of resistance was found.

After discussing the classification of the Actinomycétales, the authors give a detailed description of the epidemiology and particularly of the clinical features of cutaneous diseases induced by genera such as Actinomyces, Norcardia and Streptomyces. Histopathological and immunological studies, together with laboratory and differential diagnostics, are also examined. In the last section, present therapeutic treatments are briefly outlined.
