RESUMEN
BACKGROUND: The efficacy and safety of dupilumab in atopic dermatitis (AD) have been defined in clinical trials but limited real-world evidence on long term treatment outcomes are currently available to inform clinical decisions. OBJECTIVES: to describe long-term effectiveness and safety of dupilumab up to 48 months in patients with moderate-to-severe AD. METHODS: a multicenter, retrospective, dynamic cohort study was conducted to assess long term effectiveness and safety of dupilumab in patients with moderate to severe AD in a real-world setting. Predictors of minimal disease activity (MDA) optimal treatment target criteria (defined as the simultaneous achievement of EASI90, itch NRS score ≤1, sleep NRS score ≤1 and DLQI ≤1) were investigated. RESULTS: 2576 patients were enrolled from June 2018 to July 2022. MDA optimal treatment target criteria were achieved by 506 (21.91%), 769 (40.63%), 628 (50.36%), 330 (55.37%) and 58 (54.72%) of those that reached 4, 12, 24, 36 and 48 months of follow-up, respectively. Logistic regression revealed a negative effect on MDA achievement for conjunctivitis and food allergy at all timepoints. Adverse events (AE) were mild and were observed in 373 (15.78%), 166 (7.02%), 83 (6.43%), 27 (4.50%) and 5 (4.55%) of those that reached 4, 12, 24, 36 and 48 months of follow-up. Conjunctivitis was the most frequently reported AE during the available follow-up. AE led to treatment discontinuation in <1% of patients during the evaluated time periods. CONCLUSION: High long-term effectiveness and safety of dupilumab were confirmed in this dynamic cohort of patients with moderate to severe AD, regardless of clinical phenotype and course at baseline. Further research will be needed to investigate the effect of Th2 comorbidities and disease duration on the response to dupilumab and other newer therapeutics for AD.
RESUMEN
BACKGROUND: Advanced cutaneous squamous cell carcinoma (aCSCC) represents an area of unmet clinical need, with no standardized treatments until the recent approval of immune checkpoint inhibitors (ICIs). OBJECTIVES: The aim of the study was to describe clinical characteristics and therapeutic strategies of a real-life Italian cohort of aCSCC patients managed at the beginning of cemiplimab approval as compassionate use in Italy. METHODS: A multicenter retrospective study was performed by 10 Italian centers in the period January 1, 2018-May 31, 2020. Patients aged ≥18 years and diagnosed with aCSCC (locally aCSCC and metastatic CSCC) were eligible for the study. Analysis of patients' characteristics and treatment strategies was performed. RESULTS: 239 patients were initially recruited in the study: 19 patients were excluded due to incomplete data collection, yielding a final cohort of 220 patients, of which 191 and 220 were included for patients' clinical characteristics and therapeutic intervention analysis, respectively. Median age at the time of diagnosis was 81 years (range: 72-86); nodal metastases were detected in 64/220 (29%) patients, and distant metastatic spread was reported in 33/220 (15%) patients. Most of our patients referred chronic occupational and/or recreational sun exposure, experienced ≥1 sunburn during their lifetime, never wore hats or used photoprotective filters, and presented with signs of cumulative sun damage (solar lentigines and/or actinic keratosis). Majority of our cohort received at least one intervention directed to the primary tumor (n = 212, 96.3%); surgery and radiotherapy were the most common therapeutic choices. Immunotherapy was administered to a small number of patients as compassionate use, especially in the metastatic setting. CONCLUSIONS: Our study outlines the complex and heterogeneous clinical and therapeutic landscape of aCSCC patients at the beginning of ICI era, highlighting the need of a standardized care for this fragile and high-need patient population.

BACKGROUND: The effects on the inflammatory and tanning responses of sunlight/UVR of several oral antioxidants are still unknown. OBJECTIVE: Assess intensity, time course of the inflammatory, and tanning responses to increasing dosages of solar-simulated radiation (SSR) at baseline and after oral supplementation of an extract of Polypodium leucotomos (PLE). METHODS: Ten healthy subjects underwent phototesting with SSR with a visual and spectrophotometrical assessment of the responses with or without daily oral supplementation of two tablets containing 240 mg of PLE for a total of 15 days. RESULTS: Polypodium leucotomos supplementation induced a significant increase of the minimal erythema dose (MED), a faster recovery of the inflammation following the delivery of super-erythemal doses, and no significant changes of the minimal melanogenic dose (MMD). Spectrophotometric assessment of the Δa* in test areas exposed to equally doses of SSR did not show differences. CONCLUSIONS: Polypodium leucotomos supplementation increased the MED and induced a faster recovery of the inflammation and a stronger tanning response with no changes in the melanogenic threshold.
RESUMEN
Photodynamic therapy (PDT) with methyl aminolevulinate (MAL) has been suggested as a useful treatment option in a number of skin tumors, other than approved indications, and infections. However, evidence is poor because it is mainly supported by isolated case reports or small case series, often with conflicting results. To assess the effectiveness, tolerability and safety of off-label MAL-PDT in daily clinical practice in 20 Italian hospitals, a retrospective observational study of medical records of patients treated for off-label oncologic and infectious skin conditions was carried out. In all patients standard treatment options had been either ineffective, unacceptably toxic, or medically contraindicated. Clinical data from 145 patients were analyzed. Actinic cheilitis showed a complete remission (CR) in 27 out of 43 treated patients and CR was maintained at follow-up. CR was registered in 3 of 8, 5 of 8 and 10 of 17 treated patients who were affected by extra-mammary Paget's disease (EMPD), erythroplasia of Queyrat (QD), and invasive squamous cell carcinoma (SCC), respectively. Five out of 19 patients with cutaneous T cell lymphoma had a complete remission. Cutaneous B-cell lymphoma, malignant fibrous histiocytoma, mastocytosis and nevus sebaceous were not responsive. Warts were treated in 30 patients and 15 had a complete remission. However, periungueal and plantar lesions were much more responsive than flat and common lesions. Condylomata showed a CR in 2 out of 5 male patients but treatment was painful. Bowenoid papulosis showed only a partial improvement. Atypical mycobacteriosis and chronic cutaneous leishmaniasis were successfully treated. Submammary candidal intertrigo and interdigital intertrigo with Pseudomonas aeruginosa did not improve. Among off-label oncological uses of MAL-PDT, the therapy of actinic cheilitis was the most investigated and showed the best results. In addition, MAL-PDT was used successfully in the majority of patients with QD, EMPD and invasive SCC. Treatment of specific cutaneous infections was well tolerated and gave a good therapeutic result in a few patients, but it does not seem to give substantial advantages over conventional treatment options.

Experimental investigations have demonstrated that photodynamic therapy (PDT) with methyl aminolevulinate (MAL) may be a useful treatment in several inflammatory skin disorders and aesthetic indications. To assess the effectiveness, tolerability and safety of off-label MAL-PDT in daily clinical practice in 20 Italian hospital centers, a retrospective observational study of medical records of patients treated for off-label inflammatory and aesthetic indications was carried out. In all patients standard treatment options had been either ineffective, unacceptably toxic, or medically contraindicated. Clinical data regarding 221 patients affected by 22 different diseases were collected. The most common off-label indication was acne vulgaris, with >75% improvement in 72.8% of patients. Other disorders of the sebaceous gland, i.e. acne rosacea, hidradenitis suppurativa and sebaceous hyperplasia, were less responsive. Alopecia areata did not show any improvement. Granuloma annulare and necrobiosis lipoidica showed marked or moderate response in the majority of treated patients. The rate of patients with complete remission was lower for inflammatory skin disorders with hyperkeratosis, i.e. psoriasis (6/17) and porokeratosis (3/16). The efficacy for lichenoid dermatoses was dependent on the clinical variant (erosive and scleroatrophic were more responsive than hypertrophic). Only 1 of 6 patients with Zoon balanitis had a marked improvement. MAL-PDT of venous leg ulcers, photo-aging and hypertrophic scars led to a marked remission in 3/5, 3/6 and 5/8 patients, respectively. The treatment had to be interrupted because of strong pain and burning in 24 patients. Long term adverse events were not registered. Most patients with marked improvement had lasting remission with overall excellent cosmetic outcomes. The present findings demonstrate a high interest in off-label uses of MAL-PDT for inflammatory skin disorders. According to the observed clinical responses, safety, and favorable cosmetic results, MAL-PDT seems to have a potential therapeutic role for the treatment of granulomatous dermal disorders and follicular inflammatory diseases whereas results in other conditions are less encouraging.

BACKGROUND: Although polychlorinated biphenyls (PCBs) have been classified as human carcinogens for their association with melanoma, few data are available for other skin lesions. OBJECTIVES: To investigate the prevalence of skin disorders in a highly PCB polluted area in northern Italy, with locally produced food as the main source of human contamination, and evaluate the association between skin lesions and PCB serum levels, taking account of possible confounders. MATERIALS & METHODS: Thirty-three PCB congeners were quantitatively assessed and a total of 189 subjects were equally divided into three groups using the tertiles of total PCB serum concentrations. All subjects underwent a clinical examination and were interviewed on their risk factors and history of skin diseases. RESULTS: No statistically significant difference was found in the prevalence of skin cancer, nevi, pigmentary disorders as well as inflammatory and infectious skin diseases among the three PCB exposure groups. It should be noted that the use of questionnaires to assess subjects' past sun exposure and photoprotection is intrinsically flawed due to random error. CONCLUSION: Our study does not support the hypothesis that chronic PCB exposure, through the ingestion of contaminated food, determines an increased risk of developing skin diseases.

Approximately, 1-4% of all new melanoma cases occur in patients younger than 20 years. The clinical presentation of melanoma in the young is often challenging. We report the experience of the Melanoma Unit of University Hospital Spedali Civili of Brescia, Italy. Study subjects were drawn from 1470 patients with histologically confirmed melanoma. From this group, melanoma developed in 12 patients younger than 19 years. For each melanoma diagnosed, histologic characteristics, treatment, and outcomes were evaluated. Of the 12 patients described in this study, four were men and eight were women. The average age was 15.6 years ranging from 11 to 18 years. Regarding invasive melanomas, Breslow thickness ranged from 0.15 to 0.66 mm with a mean thickness of 0.36 mm. Primary treatment of 12 patients included wide local excision of their primary lesions. In many cases reported in literature lesions are amelanotic, nodular, and resemble pyogenic granuloma. From our case studies it was found that the clinical characteristics detected in melanomas diagnosed in childhood and adolescence have been the same as those described in adults and that the ABCDE clinical criteria may be helpful basics of melanoma.

Panniculitis and vitiligo-like lesions have been recently identified as rare cutaneous side effects of the combination of BRAF and MEK inhibitors, a standard of care in metastatic and locally advanced BRAF V600 mutated melanoma. An immune-mediated mechanism has been advocated in the pathogenesis of these skin lesions. Herein we retrospectively reviewed our institutional experience with the aim to explore the association between the occurrence of panniculitis and vitiligo-like lesions during combination therapy with dabrafenib (D) and trametinib (T) and outcome of advanced melanoma patients. Among 52 consecutive BRAF V600 mutated melanoma patients submitted to DT in our center, 12 (23%) developed immune related skin lesions (IRSLs): 8 panniculitis and 4 vitiligo. Patients with IRSLs diagnosis obtained a better disease response (83% versus 25%) (p = 0.001) than their counterpart and had a longer progression free survival and overall survival. The association of IRSLs and lower risk of disease progression (HR 0.19; CI 95% 0.04-0.90; p = 0.043) was confirmed after adjusting for major prognostic factors in multivariate analysis. IRSLs might represent an easy predictive surrogate marker for treatment response and favourable outcome in melanoma patients submitted to DT combination therapy.

BACKGROUND: Sunlight modifies the size and the dermoscopic pattern of acquired melanocytic nevi (AMN). OBJECTIVE: We investigated whether repeated exposures to equally effective suberythemogenic doses of ultraviolet (UV)A or UVB can induce changes in the dermoscopic features of AMN. METHODS: Twenty volunteers received equally effective doses of narrowband UVB or UVA1. During exposures, an AMN was covered with an opaque tape, another was shielded with the sunscreen, and another was left unprotected. RESULTS: Nevi exposed to either narrowband UVB and UVA1 showed statistically significant changes in their dermoscopic features: increased size, increase of pigment network, overall color darkening, formation of focal branched streaks, and increased number and size of brown dots and globules. LIMITATIONS: The study is a clinical cohort study on a small number of selected patients. CONCLUSION: AMN show similar changes in size and dermoscopic pattern after narrowband UVB and UVA1 exposures.

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer, accounting for 20% of all cutaneous malignancies, and has an increasing incidence in the elderly as well as in the younger population. Although most cSCC is treated with simple therapeutic procedures, advanced cSCC can lead a significant risk for morbidity, negative impact on quality of life, and death. Proper management includes distinguishing between high-risk and low-risk lesions and determining treatment accordingly. A collaboration of multidisciplinary Italian experts has given birth to these recommendations on cSCC diagnosis and management, based on a critical review of the literature, existing European (EADO-EDF-EORTC) guidelines and the expert's experience. Topics covered include diagnostic path and histopathologic assessment, tumor staging, surgical and nonsurgical procedures, follow-up and management of localized and advanced disease.

BACKGROUND: Etanercept is licensed for the treatment of moderate-to-severe plaque psoriasis in children. OBJECTIVES: The aim of this analysis was to investigate effectiveness, tolerability, and reasons for discontinuation of etanercept in a real-life cohort of children and adolescents with moderate to severe plaque psoriasis. METHODS: Data collected from a number of centers belonging to the 'Pediatric Dermatology Group' of the Italian Society of Dermatology (SIDeMaST) were examined in patients (age ≤17 years) who started treatment with etanercept from 2011 to 2015. A group of 23 patients were identified. Efficacy assessment was defined as the proportion of patients with a ≥50% and ≥75% improvement in Psoriasis Area Severity Index (PASI) at weeks 12, 24, and 52. Safety was evaluated on adverse event reporting. Reasons for discontinuation were classified as ineffectiveness, adverse events, remission, or other reasons. RESULTS: At week 12, 56.5% of patients achieved PASI 75, 86.9% achieved PASI 50. Efficacy was sustained through week 52. In 15 patients etanercept was still ongoing at the time of data collection. In three patients the therapy was suspended due to inefficacy. The medication was overall well tolerated. CONCLUSIONS: Etanercept was an effective and well-tolerated treatment in this real-life cohort of patients.

Actinic keratoses (AKs) develop as a consequence of chronic ultraviolet (UV) exposure and exist on a continuum with squamous cell carcinoma (SCC). As one of the most common conditions treated by dermatologists, AK places a significant burden on patients and the healthcare system. A range of treatments are used, including topical treatments that target the visible and subclinical lesions. The goal of such therapies is to achieve complete clearance of AKs and eliminate the risk of progression to SCC. Robust meta-analyses of trial data can provide valuable information for the optimal management of AK and cost-effectiveness evaluations of topical treatments, such as ingenol mebutate gel and diclofenac. These outcomes can facilitate prescribing physicians' decisions and shape therapeutic guidelines. Peer-reviewed meta-analysis publications and treatment guidelines favoured ingenol mebutate efficacy over diclofenac and the relative cost-effectiveness of ingenol mebutate. We discuss and critique recent evidence, from a cost-effectiveness analysis of 3% diclofenac sodium and ingenol mebutate in the treatment of AK in Italy, which has challenged this view.

Carcinoma cuniculatum is a rare variant of squamous cell carcinoma. The clinical presentation is usually a non-verrucous exophytic plaque or tumor of the plantar region with a penetration in the deep tissues. Histological examination shows a proliferation of well-differentiated keratinocytes. We describe a patient affected by a slowly enlarging tumoral lesion overlying the fifth metatarsum of the left foot. Clinical examination and radiological investigations suggested a chronic osteomyelitis and a first histological examination of a punch biopsy was suggestive of a pseudo-epitheliomatous hyperplasia. The patient underwent several cycles with systemic antibiotics without improvement. Finally, the fifth metatarso was amputated and the skin lesion was completely removed. The histological examination of the whole operatory mass allowed a diagnosis of carcinoma cuniculatum invading the bone.

BACKGROUND: The relationship between the occurrence of skin diseases and skin tattoos remains unclear. Dermatologic disorders have been reported to occur in about 2% of cases. In addition, tattoo pigment can migrate to the regional lymph nodes through the lymphatic vessels and subsequently mimic metastatic disease from melanoma. METHODS: A 23-year-old Caucasian man presented with a pigmented lesion on the left scapular region, which had slowly enlarged over time. The patient exhibited an extensive tattoo on the left upper arm, left shoulder, and part of the upper back. His medical history was unremarkable. The pigmented lesion was excised. Histology confirmed malignant melanoma. Ultrasound examination of the abdomen, neck, and inguinal and axillary lymph nodes and a total body computed tomography scan showed no sign of disease. A re-excision with 2-cm margins and sentinel lymph node biopsy (SLNB) were performed. Two grossly enlarged, black sentinel lymph nodes (SLNs) highly suggestive of melanoma metastases were removed. RESULTS: No evidence of melanoma metastasis was found in any of the sampled tissues. Large amounts of pigment were present within the subcapsular space and sinusoid areas of the two clinically suspicious lymph nodes. Immunohistochemical analysis was negative. CONCLUSIONS: Sentinel lymph node biopsy is widely performed in cutaneous melanoma. Histologic confirmation of any enlarged, pigmented SLN is essential prior to radical surgery, especially when pigmented SLNs are found near a tattoo. Tattoo pigments may deposit in the regional lymph nodes and may clinically mimic metastatic disease. A history of tattooing should be considered in all melanoma patients eligible for SLNB. In a finding of darkly pigmented nodes during SLNB, radical lymphadenectomy should be withheld until immunohistologic confirmation of metastasis in the SLN is obtained.
