Background Photodynamic therapy (PDT) is a well-known and effective treatment for non-melanoma skin-cancer. Numerous studies have also shown its effectiveness in mycosis fungoides. The aim of the study was to analyse MF patients treated with PDT at the Dermatology Unit of Bologna University. Methods We retrospectively analysed MF patients treated with PDT over the last ten years. Each PDT protocol consisted of the appliance for 3 h under an occlusive film dressing on each lesion of a one-mm-thick layer of 16% methyl aminolaevulinate (MAL) 160 mg/g cream (Metvix ® , Galderma, Paris, France). The cream was then removed and the skin was exposed to 630 nm red light from a diode lamp (Aktilite ® , Galderma Benelux, Rotterdam, the Netherlands), with a total radiation dose of 37 J/cm2 for 9 mins. A protocol of one session every month was scheduled. The treated lesions were clinically examined, before each treatment. Results Four cases, three male and one female, had been treated with PDT. Two patch lesions on the plantar area, one leg and the pubic area were treated. The number of PDT sessions ranged from 4 to 9. Two complete remissions and two partial remissions were observed. A low-to-mild burning sensation was reported during the treatment, and persisted over the next day; no further side effects were observed. Conclusions Our series shows that PDT can be considered an effective second-line treatment in patients characterised by a disease located in difficult-to-treat anatomical areas such as the feet and the pubic area.

PURPOSE: We assessed the prevalence and predictors of Chlamydia trachomatis, Neisseriagonorrhoeae and Mycoplasmagenitalium rectal infections in a population of 'men having sex with men' (MSM). METHODOLOGY: From January to November 2017, 165 MSM attending a STI outpatients clinic in Bologna (Italy) and reporting unsafe anal intercourses were enrolled. An ano-rectal swab was collected from each patient: chlamydial and gonococcal infections were diagnosed by a commercial NAAT, whereas an in-house quantitative PCR was used for M. genitalium detection. In addition, 131 urine samples and 84 pharyngeal swabs underwent testing for C. trachomatis and N. gonorrhoeae. A molecular C. trachomatis typing, a serological screening for anti-Chlamydia IgG and IgA, as well as the assessment of HIV, HCV and syphilis infections, were performed. RESULTS/KEY FINDINGS. The prevalence of C. trachomatis, N. gonorrhoeae and M. genitalium rectal infections was 27.2, 25.4 and 4.8 %, respectively. Globally, 63.1 % of cases were asymptomatic and up to 80 % of chlamydial and gonococcal infections would have been missed if the rectal site had not been tested. All the patients with rectal M. genitalium carriage were asymptomatic and characterized by low bacterial loads (30, HIV-positivity and elevated levels of anti-Chlamydia antibodies were the most significant predictors of LGV. CONCLUSIONS: Sexually transmitted rectal infections are frequent and often asymptomatic among MSM. LGV prevalence is high in our country and there is increasing evidence of symptomless cases.

Background Melanoma is an infrequent neoplasm in children and adolescents. The number of consultancies for melanocytic nevi control in the pediatric population is increased by the major anxiety of parents and pediatricians. Methods A retrospective chart review was performed in order to evaluate the incidence rate of melanoma, Spitz nevi, congenital and acquired melanocytic nevi in patients aged 14 years or less and referred to our institution from April 2010 to September 2015. Results A total of 32,755 dermatologic pediatric consultancies were performed in the considered 66 months period, including 4260 patients referred for mole control (13%). During the same period, a total of 5193 excisions of melanocytic lesions were performed (adults and pediatric patients), 259 of which were performed in 250 patients aged 14 years or less (4.98%). Only 1 in situ melanoma of the nail matrix was detected in a 12-year-old female patient (0.38% of surgical excisions). The number needed to excise (NNE) in our pediatric population, calculated by comparing the total number of excised lesions and the number of melanomas found, was 259. Conclusions Our data leads to 3 major observations: 1) the rarity of melanoma in patients with 14 years of age or less is confirmed; 2) the number of excisions performed in this pediatric population is extremely high; 3) neither the cases of melanoma and atypical Spitz neoplasm (ASN) nor the majority of Spitz nevi were referred to us for a generic mole control. Mole controls in the pediatric population should be properly addressed, incrementing the attention on specific suspicious cutaneous lesions.

A 7-day-old girl, born at term and otherwise healthy, was referred with multiple congenital skin lesions on her right arm. Physical examination showed multiple vascular slightly reticulate patches with deep purple rim and a blue-to-greyish atrophic centre on the right forearm (figure 1).
