RESUMEN
BACKGROUND: There is limited epidemiological evidence on outcomes associated with dupilumab exposure during pregnancy; monitoring pregnancy outcomes in large populations is required. OBJECTIVE: To investigate the potential association between exposure to dupilumab in pregnant women with atopic dermatitis and any adverse pregnancy, neonatal, congenital and post-partum outcomes. METHODS: We performed a multicentre retrospective cohort study across 19 Italian tertiary referral hospital. Childbearing women were eligible if aged 18-49 years and carried out the pregnancy between 1 October 2018 and 1 September 2022. RESULTS: We retrospectively screened records of 5062 patients receiving dupilumab regardless of age and gender, identifying 951 female atopic dermatitis patients of childbearing age, 29 of whom had been exposed to the drug during pregnancy (3%). The median duration of dupilumab treatment prior to conception was 22.5 weeks (range: 3-118). The median time of exposure to the drug during pregnancy was 6 weeks (range: 2-24). All the documented pregnancies were unplanned, and the drug was discontinued in all cases once pregnancy status was reported. The comparison of the study cohort and the control group found no significant drug-associated risk for adverse pregnancy, congenital, neonatal or post-partum outcomes. The absence of a statistically significant effect of exposure on the event was confirmed by bivariate analysis and multivariate analysis adjusted for other confounding factors. CONCLUSIONS: This cohort of pregnant patients exposed to dupilumab adds to the existing evidence concerning the safety of biologic agents in pregnancy. No safety issues were identified regarding the primary outcome assessed. In clinical practice, these data provide reassurance in case of dupilumab exposure during the first trimester. However, the continuous use of dupilumab throughout pregnancy warrants further research.
RESUMEN
Locally advanced (laBSCs) and metastatic basosquamous carcinomas (mBSCs) represent a therapeutic challenge. By definition, these forms are not amenable to surgery or radiotherapy, but according to literature reports, sonic hedgehog pathway inhibitors (HHIs), anti-programmed death 1 receptor antibodies (anti-PD-1), and other treatment approaches involving chemotherapy, surgery, and radiotherapy have been used. This work features 5 real-life cases of advanced BSCs, treated at the Dermato-Oncology Unit of Trieste (Maggiore Hospital, University of Trieste). In addition, a review of the current treatment options reported in the literature for laBSC and mBSC is provided, collecting a total of 17 patients. According to these preliminary data, HHIs such as sonidegib and vismodegib could represent a safe and effective first line of treatment, while the anti-PD-1 cemiplimab may be useful as a second-line option. Chemotherapy and combined approaches involving surgery and radiotherapy have been also reported to be suitable in some patients.

BACKGROUND: Patients with keloids are often younger than 30 years old and have darker skin. AIM: To evaluate the efficacy and safety of CO2 laser therapy in the management of earlobe and helix keloids in dark subjects. METHODS: A total of 21 dark patients (five men and 16 women) presented with the earlobe and ear helix keloids, with a mean age of 30.5 (±6.7) years and with phototype between III-VI, were enrolled. In order to improve their earlobe and helix keloids, all patients underwent a single session of CO2 laser therapy immediately followed by a pulsed Dye laser procedure. A single well-experienced doctor performed all treatment sessions and the response to treatment. Patients were followed-up for 6 months after termination of therapy. Clinical images were examined and collected: all patients were examined clinically and with Dermoscopy. RESULTS: The majority of the patients treated show complete remission of keloid lesions. Clinical photographs show a visible aesthetic improvement of several types of keloids in dark subjects. CONCLUSIONS: Our data demonstrate that this combined laser therapeutic protocol appears to be effective and well tolerated for the management of earlobe and helix keloids in dark subjects, with no high recurrence rate and avoiding the adverse effects and lengthy recovery time.

Keratinocyte skin cancers are the most frequent malignancy, accounting for approximately 30% of all cancers. Although beta genus HPV are the main etiologic agents for squamous cell carcinoma development in patients with epidermodysplasia verruciformis and organ transplant recipients, their role in non-melanoma skin cancer (NMSC) progression in the general population remains controversial. The aim of our review is to summarize current scientific data and to systematically analyse evidence regarding the role of HPV in keratinocyte skin cancers. A total of 2284 patients were included, of which 724 with actinic keratoses, 290 with Bowen's disease, 949 with cutaneous squamous cell carcinomas and 321 with keratoacanthomas. In the case of actinic keratoses, the majority were positive for beta (n = 372, 58.49%) and gamma HPV (n = 256, 40.25%) and only a few (n = 6, 0.94%) were positive for alpha subtypes. Similarly, most of the cutaneous squamous cell carcinomas were positive for beta (n = 248, 55.98%) and gamma HPV (n = 172, 33.82%) and 23 cases (2.42%) were positive for alpha subtypes. Bowen's disease lesions were mostly positive for beta (n = 43, 55.84%) and alpha HPV (n = 30, 38.96%), in contrast to the gamma genus (n = 4, 5.19%). Keratoacanthomas showed a high distribution among beta genus (n = 79, 50.31%) and an equal proportion between alpha (n = 39, 24.84%) and gamma (n = 39, 24.84%) genera. Studies published so far identifying HPV in keratinocyte skin cancers reflect the difference in detection methods rather than a type-specific tendency towards either actinic keratoses, Bowen's disease, squamous cell carcinoma or keratoacanthoma. On the other hand, recent evidence regarding the role of HPV vaccination in patients with non-melanoma skin cancer brings into perspective the idea of a beta-HPV vaccine or a combined alpha and beta-HPV vaccine that could be used as an adjuvant treatment measure in patients with recalcitrant non-melanoma skin cancer.

BACKGROUND: Amelanotic/hypomelanotic lentigo maligna and lentigo maligna melanoma (AHLM/LMM) may be very difficult to diagnose at an early stage. OBJECTIVES: To quantify the predictive value of dermoscopic and reflectance confocal microscopy (RCM) features for AHLM/LMM. METHODS: Dermoscopic and RCM images of histopathologically diagnosed AHLM/LMM, amelanotic/hypomelanotic benign lesions (AHBL), and amelanotic/hypomelanotic basal and squamous cell carcinomas (AHBCC/AHSCC) of the head and neck from consecutive patients were retrospectively collected and blindly evaluated by three observers to assess presence or absence of dermoscopic and RCM criteria. RESULTS: Overall, 224 lesions in 216 patients including LM/LMM (n = 55, 24.6%), AHBL (n = 107, 47.8%) and AHBCC/AHSCC (n = 62, 27.7%) were analysed. Multivariable analysis showed that milky-red areas (OR = 5.46; 95% CI: 1.51-19.75), peripheral light brown structureless areas (OR = 19.10; 4.45-81.96), linear irregular vessels (OR = 5.44; 1.45-20.40), and asymmetric pigmented follicles (OR = 14.45; 2.77-75.44) at dermoscopy, and ≥3 atypical cells in five fields (OR = 10.12; 3.00-34.12) and focal follicular localization of atypical cells at dermo-epidermal junction (DEJ) (OR = 10.48; 1.10-99.81) at RCM were significantly independent diagnostic factors for AHLM/LMM vs. AHBL. In comparison with AHBCC/AHSCC, peripheral light brown structureless area (OR = 7.11; 1.53-32.96), pseudonetwork around hair follicles (OR = 16.69; 2.73-102.07), and annular granular structures (OR = 42.36; 3.51-511.16) at dermoscopy and large dendritic (OR = 6.86; 3.15-38.28) and round pagetoid cells (OR = 26.78; 3.15-227.98) at RCM led to a significantly increased risk of diagnosing AHLM/LMM. CONCLUSIONS: Amelanotic/hypomelanotic lentigo maligna and lentigo maligna melanoma may have the same dermoscopic features of AHM on other body sites, such as milky red areas, peripheral light brown structureless areas and linear irregular vessels. These features, asymmetric pigmented follicles and at RCM ≥ 3 atypical cells in five fields and focal follicular extension of atypical cells at DEJ may help in recognizing AHLM/LMM even when LM conventional features (e.g., obliteration of hair follicles under dermoscopy and large pagetoid cells under RCM) are absent or present only in very small areas of the lesion.

Background and Objectives: Photo/chrono-aging is usually expressed as facial discolouration, wrinkles, redness, elastosis, laxity, and dehydration, thus representing major signs of ageing that often lead to a negative phycological impact on a patient's quality of life. Several types of treatment have been tested during the last decade, especially laser treatments. This article aims to share our experience in the treatment of photoaging with a new 675 nm laser source system on facial chrono-ageing. Materials and Methods: Thirty-five (35) patients were treated with the 675 nm laser device: 32 females (mean age 49 years) and 3 men (mean age 57 years), with Fitzpatrick skin types I-III (9% type I, 43% type II, 48% type III), facial wrinkles and hyperpigmented spots. The efficacy of this treatment was assessed using the Modified Fitzpatrick Wrinkles Scale (FWS), which was calculated before starting the treatment and after 6 months. The pain was evaluated using the VAS Pain Scale. Results: All 35 patients showed a significant improvement in facial wrinkles according to the FWS (from 1.96 to 1.73 at the 3-month follow-up, up to a value of 1.43 at 6 months). In a small group of patients, it was observed that 44% of them showed vascular moderate improvement and that 13% showed a vascular marked improvement after treatment. No side effects were detected except a mild erythematous rash in two patients, and the VAS Pain scale was assessed at 1.17. Conclusions: Red Touch allows a uniform and stable result to be achieved over time with minimum discomfort.

Background and Objectives: For many years, fully ablative laser treatments, particularly those performed with a carbon dioxide (CO2) laser, were regarded as the gold standard for resurfacing. This study's goal is to assess the depth that can be reached by a new CO2 scanner system, through a skin model with greater dermal thickness, to use in the treatment of deep scarring. Materials and Methods: Male human skin tissue was laser-treated using a CO2 fractional laser and a new scanning system, and all samples were fixed in 10% neutral buffered formalin, dehydrated using a series of crescent alcohol, embedded in paraffin, sectioned in series (4-5 µm thick), stained with haematoxylin and eosin (H&E), and then analysed under an optical microscope. Results: From the epidermis through the underlying papillary and reticular dermis to various depths of the dermis, microablation columns of damage and coagulated microcolumns of collagen were observed. The reticular dermis was fully penetrated up to 6 mm at higher energy levels (210 mJ/DOT), resulting in deeper tissue injury. Although the laser might penetrate further, the skin stops there, leaving just the fat and muscular tissue. Conclusions: The deep layers of the dermis can be penetrated by the CO2 laser system throughout the entire dermal thickness when using the new scanning system, suggesting that this laser's potential impact, at the selected settings, covers all skin targets required to perform superficial or deep treatments on any dermatological issue. Finally, patients who have problems, such as morbid scar-deep complications, which affect their quality of life, are more likely to profit from this innovative technique.

Background: Dermal fillers for soft tissue for the treatment of face sagging, volume loss, and wrinkles have become popular among patients of all ages and ethnicities, and their use is becoming increasingly widespread. Aim: the goal of this study was to evaluate the effectiveness and safety of a micro-pulsed, 1444 nm Nd:YAG laser on dermal filler complications, in particular on granuloma management. Methods: A subcutaneous, 1444 nm Nd:YAG laser was used on five female patients (range age 52-68 years) with hyaluronic filler granulomas located on the face (two on the cheek area and three on the lips); three patients had self-injected the filler, buying it online. Before and after the therapy, the patients received a skin ultrasound to determine the form and location of the granulomas and to determine if there had been a full or partial resolution. During this study, all possible adverse effects at the treatment site were monitored. The 5-point Global Aesthetic Improvement Scale (GAIS) (0 point-no change; 1 point-25%, mild improvement; 2 points-50%, moderate improvement; 3 points-75%, good improvement; 4 points-100%, excellent improvement) was recorded at a 3-month follow-up. Results: good results were obtained in the treatment of filler granulomas with the intralesional 1444 nm laser, even if just a single treatment was performed (one intervention was effective for curing granulomas up to 5 mm in diameter). Three patients were satisfied with excellent improvement, and two patients experienced good improvement. The results are functional and aesthetically satisfying, as shown by photographic assessment. At the last follow-up, the granuloma had reduced or completely disappeared in all cases, and no infections, burns, scarring or fibrosis, episodes of severe bleeding, or other serious adverse effects had been reported. All subjects tolerated the post-treatment period well. Conclusions: Our findings showed that granuloma treatment with an intralesional 1444 nm Nd:YAG laser is a minimally invasive, easy, fast, efficient, and low-risk procedure.

Introduction: Spitz nevi (SN) include a wide range of benign melanocytic nevi, which are controversial due to their morphologic resemblance to melanoma (MM). Aim: To describe dermoscopic and reflectance confocal microscopic (RCM) features of SN compared to MM and assess the RCM utility in the differential diagnosis. Material and methods: We performed a multicentre retrospective analysis of MM and SN evaluated with dermoscopy and reflectance confocal microscopy. Three RCM mosaics were obtained for each lesion. Nine dermoscopic and twenty-one microscopic features were assessed for each lesion. Results: A total of 26 lesions (15 SN and 11 MM) were included. Dermoscopically, most SN showed a "starburst" pattern. Asymmetry was marked in 8 MM. There were 6 dermoscopic features significantly more prevalent in MM than in SN. RCM showed that an atypical honeycomb pattern, atypical infiltration, and disarray of the epidermis were significant for MM. SN mostly revealed a typical honeycomb pattern. At the DEJ, most of SN had a meshwork pattern; MM revealed an atypical meshwork pattern. Atypical cells and sheet-like structures were observed in most MM. Conclusions: A combined approach using dermoscopy and RCM supports the differential diagnosis of SN and MM. Although our study showed some significant differences between SN and MM in RCM, further research on a larger group should be considered.
RESUMEN
PURPOSE OF REVIEW: Coronavirus disease 2019 (COVID-19) is a well established respiratory tract illness. Recent studies in adults and children have shown an increasing number of patients reporting polymorphic cutaneous manifestations during COVID-19, including different types of rashes, from maculopapular, vascular, vesicular to atypical forms. RECENT FINDINGS: Although pathogenesis of skin manifestations is still not fully understood, it has been proposed that cutaneous involvement during COVID-19 may be the results of the activation of the immune response against severe acute respiratory syndrome coronavirus-2, the reactivation or co-infection of herpesviruses or drug hypersensitivity. SUMMARY: According to available literature, skin manifestations in patients with COVID-19 may be categorized on the basis of their clinical presentations as follows: erythematous rashes, lesions of vascular origin, vesicular rash, urticarial rash and acute generalized exanthematous pustulosis (AGEP), erythema multiforme and other polymorphic erythema/atypical reactions. Prompt recognition of these cutaneous manifestations represents a crucial point to facilitate diagnosis and management of COVID-19 patients.

In recent years, the category of hedgehog pathway inhibitor (HHI) has shown great results in patients with advanced basal cell carcinoma (aBCC), but few real-life data on efficacy and safety profile of sonidegib are available. We report our management of locally advanced BCCs (laBCCs) with sonidegib, also describing the favorable response of locally advanced basosquamous carcinomas (laBSCs) treated with this hedgehog signaling inhibitor. Sonidegib was generally well tolerated and it achieved high response rates, improving quality of life. Our single-center experience could be useful to better delineate long-term efficacy and tolerability profile demonstrated in the trials described in literature. Moreover, our cases provide preliminary evidence that sonidegib might be effective for laBSC.

Carbon peel laser treatment has been described for the improvement of skin texture, with pore reduction and acne lesion treatment. The technique consists of applying a carbon mask to the face for about ten minutes followed by laser irradiation with a Q-switched 1064 nm laser. This mechanism of action seems to be related to small carbon molecules binding both the corneocytes and serum within the hair follicles; the effect of the laser eliminates carbon bound to skin particles and the high temperature generated reduces sebum production by sebaceous glands and inhibits Cutibacterium acnes replication. Although this method was described 20 years ago, scientific data supporting its efficacy and safety have only recently been reported in small case series. For this reason, we performed a retrospective study including patients treated from January to May 2022 in the context of a private practice. Even if this study is limited by the low number of patients and its retrospective nature, this is the first research to show that carbon peel laser, performed with a standardized technique, is an effective and safe treatment for patients with acne lesions, showing pores and wrinkles, and is able to improve the overall skin aspect.

Background and objectives: Dermoscopy is a useful tool for the early and non-invasive diagnosis of skin malignancies. Besides many progresses, heavily pigmented and amelanotic skin tumors remain still a challenge. We aimed to investigate by dermoscopy if distinctive morphologic characteristics of vessels may help the diagnosis of equivocal nodular lesions. Materials and Methods: A collage of 16 challenging clinical and dermoscopic images of 8 amelanotic and 8 heavily pigmented nodular melanomas and basal cell carcinomas was sent via e-mail to 8 expert dermoscopists. Results: Dermoscopy improved diagnostic accuracy in 40 cases. Vessels were considered the best clue in 71 cases. Focusing on the diameter of vessels improved diagnosis in 5 cases. Conclusions: vascular diameter in addition to morphology and arrangement may be a useful dermoscopic clue for the differential diagnosis of clinically equivocal nodular malignant tumors.

OPINION STATEMENT: Recently introduced systemic therapies for locally advanced and metastatic non-melanoma skin cancers (NMSCs) are paving the way for neoadjuvant approach. Although none of the therapeutic options has currently gained indication in this setting, neoadjuvant approach for NMSCs is an open field and we are likely to see huge developments in the near future. Targeted therapy with sonic hedgehog pathway inhibitors is very effective in locally advanced or multiple basal cell carcinomas while immunotherapy with immune checkpoint inhibitors appears to be promising for advanced cutaneous squamous cell carcinoma and Merkel cell carcinoma. To date, targeted therapy and immunotherapy represent the frontiers in NMSC therapeutic management and, according to recent studies, good results can be achieved.

Androgenetic alopecia (AGA) with its precursor miniaturization of anagen phase (MA) and telogen effluvium (TE) represent nonscarring hair loss diseases which causes moderate to severe aesthetic and psychologic discomfort in affected people. Several therapeutic approaches have been tested through the latest decades, with different degree of success. In this study we aim to analyze the efficacy and outcome of an innovative therapeutic protocol, named TRICHOBIOLIGHT, a combination of active principles conveyed by mesotherapy directly on the scalp with a subsequent photobiostimulation session with LED light (630 nm). About 107 patients (49 women, 58 men, mean age 45-year-old) with clinical and trichoscopic diagnosis of MA, AGA, and TE have been enrolled at Skin Center of L'Aquila, Avezzano and Pescara (Italy) and subsequently treated with the TRICHOBIOLIGHT protocol. 4 patients dropped out at the beginning of the study: 2 patients because of an histological diagnosis of scarring alopecia and lichen scleroatrophicus, and 2 patients dropped out because of adverse reaction to the treatment. Excellent to good outcome have been reached in the 82.5% of patients (85/103), 9 patients (8.7%) reached a sufficient result while 7 patients (6.8%) partially respond to the treatment. Two patients (2%) did not respond at all. TRICHOBIOLIGHT is a promising protocol, working through the combined action of the active principles and the photobiostimulation, that lead to a strengthening and thickening of the residual hair, giving an optical thickening effect that provides high quality aesthetic results and, consequently, appreciable psychological results.

Acne is a highly common skin disease especially among teenagers. Modern acne treatments are based also on the use of moisturizers, cleansers and sunscreens. In choosing the right cleanser, it is important to consider some aspects: the interaction between skin type and the cleanser, the optimal time and method of cleaning and the cosmetic perception of the patient. The aim of our review is to highlight the importance of choosing the most suitable topical dermocosmetics for the different skin types, as well as the most effective timing and method to combine dermocosmetics with the standard acne treatment. A search in literature for selected key words was performed using PubMed. Additional papers were identified based on author expertise. Treatment of acne patients should include education for proper daily skin hygiene, including protection from environmental damage. However, given the low number of clinical studies on cleansers, it is difficult to make reliable recommendations. The correct choice and use of topical dermocosmetics are fundamental in the management of acne patients. Daily use of moisturizers, cleansers and sunscreens can reduce both inflammatory and non-inflammatory acne lesion counts and may be helpful for acne treatment if combined with specific drugs.

Actinic keratoses (AK) have been described as either intraepithelial keratinocytic dysplasia that can evolve into invasive squamous cell carcinoma (SCC) or as in situ SCC that can progress into an invasive form. A retrospective study was conducted to compare outcomes of three different topical therapies for patients with single AK (<4): cryotherapy, CO2 laser and 5-fluorouracil 0.5%/salicylic acid 10%. We included 72 patients who presented at the Dermatology Clinic of Maggiore Hospital of Trieste between 1 November 2019 and 31 January 2020 for the treatment of AKs. All treatments led to a significant reduction in the average diameter of AK. Pain felt by patients was significantly lower after 5-FU 0.5%/SA 10%. Side effects appeared similarly distributed among the three groups, with erythema and crusts being the most frequent. Aesthetic outcomes were highest in the 5-FU 5%/SA 10% group, as evaluated by both the patient and the operator. Cryotherapy, CO2 laser and 5-FU 5%/SA 10% were all effective, with no significant efficacy differences among them. Additionally, 5-FU 5%/SA 10% was proved to have the best aesthetic result and to cause the least pain, while necessitating long-term administration. This should be taken into account for patients with low pain tolerance and low treatment adherence. Cryotherapy and CO2 laser have the advantage of requiring a single session, which might be more suitable for uncooperative patients.

BACKGROUND: Surgery is the best treatment for basal cell carcinoma (BCC); however, incomplete excisions are possible. OBJECTIVE: Assessment of the accurateness of dermoscopy and clinical evaluation in the detection of borders of BCC and description of dermoscopic findings in clinically healthy tissue surrounding BCC. MATERIALS AND METHODS: Eighty-eight lesions with clinical dermoscopic diagnosis of BCC were examined clinically and dermoscopically, to delineate the correct site of surgical incision, demarcating the respective margins with colred dermographic pencils. Specific dermoscopic features were searched in the skin adjacent to the demarcated clinical margin. RESULTS: In 29 of 88 lesions, clinical and dermoscopic margins of the tumor coincided. In the remaining 59 (67%), 10 (16.9%) presented, in the lesion area identified under dermoscopy, classical criteria for BCC and 57 (96.6%) nonclassical criteria. Differences between clinical and dermoscopic margins were significantly more frequent in superficial BCCs (p = .006). The frequency was not significantly different (p = .85) in relation to body sites. CONCLUSION: Dermoscopy improves the identification of margins for surgical excision in BCC. The observation of nontraditional dermoscopic criteria of BCC, mainly pink-white areas and short telangiectasias in the area between clinically and dermoscopically detected margins, helps to define the actual tumoral margins and to achieve a really radical excision.

PURPOSE OF REVIEW: To evaluate noninvasive imaging techniques in the management of skin cancers. RECENT FINDINGS: In the last decades, a wide range of noninvasive imaging methods has been developed in the field of dermatooncology with the aim to detect and assess the several structural and molecular changes that characterize skin cancer development and progression. SUMMARY: In this review, we discuss the current and emerging applications of noninvasive imaging approaches in skin cancer management, such as digital photography, dermoscopy, ultrasound sonography, reflectance confocal microscopy, optical coherence tomography, electrical impedance techniques, Raman spectroscopy, multispectral imaging, fluorescence imaging, and multispectral optoacustic tomography.
