Introduction: Teledermoscopy using smartphone-based applications is becoming more and more important in a setting of increasing frequency of skin cancer and difficult access to specialized care. The TELESPOT project aimed to provide rapid diagnosis and speed up patient flow between primary healthcare centers and a tertiary care center in Belgium. The aim of the present study is to describe the development of an in-house smartphone-based dermoscopy application, evaluate its real-life value in a series of primary healthcare centers, and present preliminary diagnostic data. Methods: Modified Likert scales were used to assess patient and general practitioner (GP) satisfaction rates for the system. Furthermore, a total of 105 photographic and dermoscopic images were acquired in a series of 80 patients at participating centers. Results: Overall, patient and GP satisfaction levels were 89% and 94%, respectively. Highpriority management was recommended in 7.6% of cases (8/105: 3 basal cell carcinoma, 1 primary cutaneous B-cell lymphoma, 1 Spitz melanocytic nevus, 1 congenital nevus, 1 in situ melanoma, and 1 invasive melanoma, proven by histology). Conclusions: The primary healthcare centers were highly satisfied with the TELESPOT project in terms of user-friendliness, efficacy, and reliability as well as in providing a reinforced image of first-line medicine efforts in combating skin cancer.

Background Tralokinumab, the first fully human monoclonal antibody that binds specifically to interleukin-13, was safe and effective for treating atopic dermatitis (AD) in clinical trials, but real-life experience is still limited. Objectives The objective of this study was to evaluate the effectiveness and safety of tralokinumab in severe AD in a reallife multicenter prospective cohort. Methods Adult patients with severe AD were enrolled between January 2022 and July 2022 and received tralokinumab subcutaneously for 16 weeks. Objective and subjective scores were collected at baseline, weeks 6 and 16. Adverse events were reported throughout the study. Results Twenty-one patients were included. An improvement of at least 75% on the Eczema Area and Severity Index (EASI 75) was achieved in 66.7% of patients at week 16. The median objective and subjective scores at week 16 were significantly (p < 0.001) lower than those at baseline. Combination with cyclosporine was sometimes necessary at the beginning of treatment, and addition of upadacitinib was required for some patients with very severe disease during the treatment. The most frequent adverse events were flares of eczema (23.8%) and reactions at injection site (19.0%). No cases of conjunctivitis were reported. Four patients (19.0%) discontinued treatment. Conclusions Tralokinumab is an effective first-line biotherapy for severe AD. However, therapeutic response may be progressive. Safety data were reassuring. Atopic dermatitis flares or reactions at the injection site may lead to discontinuation of treatment. A history of conjunctivitis on dupilumab is not a contraindication to the initiation of tralokinumab. Key PointsTralokinumab, a monoclonal antibody anti-interleukin-13 approved for the treatment of severe atopic dermatitis in adult patients, was effective and safe in clinical trials, but real-world data are limited.

Introduction It remains unclear whether multiple primary melanoma (MPM) patients have a worse survival prognosis compared with single primary melanoma (SPM) patients. Objectives To investigate the demographics, histological features, and survival of MPM versus SPM patients. Methods Cox regression analyses compared survival between SPM and MPM patients. Furthermore, demographics and histological features of the MPM cohort were compared with the SPM patients retrieved from dermatopathology files between 2000 and 2019. Results Out of 3853 melanoma patients, 95 MPM patients were retrieved: 81 with two primary melanomas (85.2%) and 14.8% with three or more. Mean Breslow of the first melanoma was 0.84 mm [minimum (min): 0 mm, maximum (max): 16 mm, standard deviation (SD) 1.77] versus 0.37 mm (second MPM) (min: 0 mm, max: 2.5 mm, SD 0.50) and 0.33 mm (third MPM) (min: 0 mm, max: 0.6 mm, SD 0.22). The mean Breslow for the second MPM was significantly higher for men than women (0.59 mm versus 0.27 mm). First and second melanoma in MPM patients developed on preexisting melanocytic nevi in 13% and 12%, respectively. In contrast with the mean age of primary melanoma in Belgium for women (58.2 years) and men (63.3 years), MPM patients developed their first melanoma earlier, at 44.8 years and 54.6 years, respectively. The mean distribution of anatomical localization of primary and secondary melanoma was highly similar in women, whereas in men a shift towards lower extremities was observed (19% versus 28%). The thicker the primary melanoma was, the sooner the second appeared. Follow-up (2–4/year) versus (1/year) yielded a mean Breslow of 0.29 mm and 0.55 mm, respectively. Cox regression analysis with time-varying covariate revealed a tendency for a worse prognosis in 5-year survival rates, but this was not statistically significant ( p = 0.09). Patient phenotypes were not available on the histological reports. Conclusion A closer follow-up regimen of MPM versus SPM patients is probably justified.
