Available evidence to guide clinicians in the management of psoriasis patients with a history of malignancies is scarce. The latest generation of biological drugs is traditionally considered to be safe in patients with previous malignancy, although only case reports and short case series on the use of biological drugs in this population are available in the literature. In this paper, we present the experience of our clinic on 37 psoriatic patients with a previous diagnosis of neoplasia treated subsequently with biological drugs. Subsequently, a systematic review of the literature was performed and 38 cases were found. The main biologic used in our patients and the patients described in the literature was secukinumab. In both populations treatment with biologics was safe, disease progressions reported were not related to treatment. Based on our experience, which is the largest currently available, and the cases reported in the literature the treatment of psoriasis in patients with previously diagnosed cancer with biologics against TNFalpha, IL17, IL23, and IL12 would appear to be safe. The first experience on the use of Risankizumab and brodalumab on this special population is also reported in our series.

Introduction: Atopic dermatitis (AD) has substantial negative impact on patients' quality of life. Although considerable advances have been made in understanding the pathogenesis and its treatment, there is still limited transfer of this knowledge into daily management. Aiming to identify unmet needs in clinical management of patients with AD, we used a Delphi consensus process.

Methods: A set of statements regarding diagnosis, management, prognosis, and treatment was identified by five experts (Steering Committee). Then, the Steering Committee and a second group of four clinicians were involved in a Delphi process. Lastly, agreement was assessed in a larger panel of Italian clinicians.

Results: Overall, 37 clinicians participated to the process. 17 statements reached strong agreement and 2 reached weak agreement.

Conclusions: In general, the statements reflected the need for accurate and effective diagnostic criteria to support clinical experience, especially in the atypical forms of AD. Moreover, prognostic criteria are needed to predict the duration of adult-onset AD. The identification of biomarkers was considered to be useful for clinical management of AD at all stages of disease. Lastly, greater emphasis should be placed on patient education and development of effective tools that can aid informing patients about their disease and its treatment.

Background: Topical measures are the mainstay treatment for postinflammatory hyperpigmentation (PIH). Numerous studies have assessed the efficacy of topical medications for the treatment of PIH, but few have evaluated the quality of evidence supporting these topical therapies. We performed a systematic review to evaluate the evidence of topical treatments for PIH.

Methods: We included English-language studies that evaluated topical medications for PIH. We searched PubMed, MEDLINE, and EMBASE from conception to March 29 2021. We used the modified Grading of Recommendations, Assessment, Development and Evaluation scale (GRADE) scale to assess quality of evidence.

Results: Forty-seven of 1,224 studies with 1,853 subjects were included. Topical agents with high-quality studies included retinoids, hydroxy acids, corticosteroids, thiamidol, niacinamide and plant-derived products. Sunscreens with SPF30 or greater was recommended in almost every study. Common side effects included desquamation, burning, stinging, dryness, and pruritus.

Conclusions: Retinoids, hydroxy acids and broad-spectrum sunscreen were supported by the greatest number of high-quality studies. Ongoing inflammation may be subtle, especially in darker skin phenotypes. Herein, we proposed an evidence-based algorithm for PIH based on the high-quality studies. There is a need to adopt a validated outcome measure for PIH to better compare efficacy between various treatments in future studies.

Objectives: Melasma is a chronic acquired condition characterized by grayish-brown macules and patches with a distinct border on the face. Although various treatments methods have been suggested for treating melasma, none has been completely successful. The aim of the study was to compare the efficiency of erbium: yttrium-aluminum-garnet (Er:YAG) laser and 4% hydroquinone (HQ) with the effects of intradermal tranexamic acid (TA) and 4% HQ for the treatment of refractory melasma.

Methods: The study included 31 female patients with refractory melasma. The left or right side of the patient's face was chosen randomly to receive laser therapy with topical HQ on the one side (i.e. the laser side) and intradermal injection of TA plus topical HQ on the other side (i.e. the mesotherapy side). Digital photography was performed at baseline, at the end of the treatment, and three months after the treatment as follow-up. Two independent dermatologists evaluated the modified Melasma Area and Severity Index (mMASI) score according to the pictures. Overall, 27 patients completed the study and went through the clinical evaluation.

Results: Treatment using HQ in combination with either Er:YAG laser therapy or intradermal injection of TA significantly improved the hemi-mMASI and resulted in higher patient satisfaction. While the improvement was not significantly different between the two regiments after the treatment and upon follow up and both were equally efficient in the treatment of refractory melasma (p = 1.308), recurrence rate was higher after treatment with Er:YAG laser than TA (12% vs 34%).

Conclusion: This study confirmed the comparable efficacy of TA plus topical HQ versus Er:YAG laser plus topical HQ for the treatment of refractory melasma. Both groups improved significantly and no subject left the treatment because of adverse effects.

A significant barrier to the usage of isotretinoin has been concerns regarding its adverse effect profile. The dose-dependent mucocutaneous side effects of isotretinoin are well recognized and easily managed, particularly if a lower dose is used. A possible association with depression has gained widespread media attention and is a source of concern for many patients and their carers, but data from prospective studies and recent meta-analyses have been reassuring. Furthermore, there has been much confusion amongst both patients and physicians regarding a possible association with inflammatory bowel disease, as well the ocular and rheumatological adverse effects of isotretinoin. We provide an update on the evidence surrounding the adverse effects of isotretinoin and discuss practical strategies to prevent and manage these adverse effects. We also discuss appropriate laboratory monitoring for patients taking isotretinoin.

Background: Trends in phototherapy utilization including its main clinical indications were last characterized by Luersen et al. for the time period of 1997-2010. In this study, we update data on the use of phototherapy in the United States from 2015 to 2018.

Methods: We queried the National Ambulatory Medical Care Survey (NAMCS) data on the number of phototherapy visits as well as demographics and associated dermatoses.

Results: There were approximately 1.31 million outpatient phototherapy visits during the study period with a decreasing trend over time. Leading indications for phototherapy were dermatitis not otherwise specified (NOS), (25.7%) followed by atopic dermatitis (AD) (11.7%), and pruritus (9.7%).

Conclusion: There is a downtrend in the use of phototherapy from 2015 to 2018. Psoriasis is no longer the main indication for phototherapy, which may be due to the advent of highly effective novel biologics.

Background: Erroneous diagnoses of melanocytic lesions (benign, atypical, and malignant types) result in inappropriate surgical treatment plans.

Objective: To propose a deep learning (DL)-based fully automated diagnostic method using whole slide images (WSIs) for melanocytic lesions.

Methods: The method consisted of patch prediction using a DL model and patient diagnosis using an aggregation module. The method was developed with 745 WSIs and evaluated using internal and external testing sets comprising 182 WSIs and 54 WSIs, respectively. The results were compared with those of the classification by one junior and two senior pathologists. Furthermore, we compared the performance of the three pathologists in the classification of melanocytic lesions with and without the assistance of our method.

Results: The method achieved an accuracy of 0.963 and 0.930 on the internal and external testing sets, respectively, which was significantly higher than that of the junior pathologist (0.419 and 0.535). With assistance from the method, all three pathologists achieved higher accuracy on the internal and external testing sets; the accuracy of the junior pathologist increased by 39.0% and 30.2%, respectively (p < .05).

Conclusion: This generalizable method can accurately classify melanocytic lesions and effectively improve the diagnostic accuracy of pathologists.

Background: As new targeted therapies continue to emerge for atopic dermatitis (AD), comparisons between agents are necessary to inform clinical decision-making.

Objectives: Assess the efficacy of biologics and oral small molecules on the clinical signs, symptoms, and quality of life in AD.

Methods: A systematic literature review identified phase II and III randomized clinical trials of biologics and oral small molecules in AD. Clinical benefit was assessed for three outcome measures: Eczema Area and Severity Index (EASI), Dermatology Life Quality Index (DLQI), and Peak Pruritus Numerical Rating Scale (PP-NRS) by performing a meta-analysis using the inverse variance heterogeneity model ((IVhet)).

Results: The highest achievement of 75% reduction in EASI was seen with the higher dose of upadacitinib (30 mg) followed by abrocitinib and lebrikizumab, which outperformed dupilumab. Similarly, the highest proportion achieving at least a 4-point reduction of PP-NRS was seen with lebrikizumab followed by upadacitinib and abrocitinib which had greater reduction of itch than dupilumab. Abrocitinib had the greatest improvement in DLQI.

Conclusions: Upadacitinib, abrocitinib, and lebrikizumab had greater improvement of clinical signs, symptoms, and quality of life in AD compared to dupilumab and other targeted therapies.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is a rare, cutaneous lymphoma involving subcutaneous adipose tissue. SPTL is associated in less than 20% with hemophagocytic syndrome (HPS). A 5-year overall survival rate is inferior in patients with SPTL and HPS (46%) as compared with 91% in patients without HPS. No standardized therapy for SPTCL has yet been established. This is a case of 35-year-old Caucasian man with a one-month history of B symptoms with the suspicion of Still's disease, at admission with leucopenia, high LDH, ferritin, sIl-R2, and triglycerides levels, hepatosplenomegaly, small right supraclavicular nodule, and irregular thickening of trunk subcutaneous tissue. The abdomen MRI showed generalized thickening of mesentery and colonic mucosa. In the patient, diagnosis of SPTCL was established with secondary HPS. CHOEP chemotherapy and modified HLH 2014 protocol were applied with subsequent high dose chemotherapy (BEAM) supported by autologous stem cells transplantation. Treatment was complicated by pancytopenia and pneumonia. The outcome of the disease treated by intensive protocol seems to be good.

Atopic dermatitis is a common, chronic and recurrent inflammatory skin disease, which often appears in childhood but can last into adulthood. It negatively impacts patients, their families and society in general. There is a therapeutic unmet need, with patients requiring new drugs that are safe and effective. The increasing knowledge of the pathophysiology of AD and the role of the Janus kinase (JAK) and signal transducer and activator of transcription (STAT) pathway in the development and maintenance of AD, has led to the development of agents blocking this intracellular signaling pathway, the JAK inhibitors. Baricitinib shows high selectivity for JAK1 and JAK2, making it appealing for the treatment of this condition. Phase II and phase III trials evaluated the efficacy and safety of baricitinib in the treatment of AD, and the results have been encouraging, showing a good efficacy and a favorable safety and tolerability profile. At the end of 2020, EMA approved baricitinib for the treatment of adult patients with moderate-to-severe atopic dermatitis who are candidates for systemic therapy, increasing the therapeutic option for this debilitating disease.
