RESUMO
Introduction: Basal cell carcinoma (BCC) represents around 80% of all malignant skin cancers worldwide, constituting a substantial burden on healthcare systems. Due to excellent clearance rates (around 95%), surgery is the current gold-standard treatment. However, surgery is not always possible or preferred by patients. Numerous non-surgical therapies, sometimes combined, have been associated with promising tumor free survival rates (80-90%) in non-melanoma skin cancers (NMSCs). Most research has enrolled superficial basal cell carcinomas (sBCCs), with limited recent studies also involving low-risk nodular BCCs (nBCCs). Given lower efficacy rates compared to surgery, close monitoring during the follow-up period is essential for patients treated with non-surgical therapies. Monitoring with dermoscopy is constrained by low sensitivity rates. Reflectance confocal microscopy (RCM) is more sensitive in monitoring non-surgically treated NMSCs. Case presentation: A 41-year-old woman with a single nBCC relapse following photodynamic therapy (PDT) located on the dorsum of the nose presented to our center. Given the aesthetically sensitive location of the lesion and the patient's preference for a non-surgical approach, a combined treatment of CO2 laser and PDT was prescribed. A superpulsed CO2 laser (power: 0.5-3 W, frequency: 10 Hz, spot size 2 mm) with two PDT sessions (2 weeks apart) were conducted. At 6 weeks follow-up, monitoring performed with RCM revealed a reduction but not eradication of basaloid tumor islands. Another 2 sessions of PDT were recommended. At 3, 12 and 30 months of follow-up, the nasal dorsum area of the previous nBBC lesion was noted to be slightly hypopigmented (observed clinically), with a mild erythematous background (observed by dermoscopy). RCM evaluation confirmed the absence of RCM BCC criteria. The cosmetic outcome was very much improved. Conclusions: Combined CO2 laser and PDT for the treatment of a localized nBCC on the dorsum of the nose of a 41-year-old proved to offer tumor free survival at 30-month follow-up, as monitored with RCM. RCM is useful for the evaluation of non-surgical therapies as it has comparably higher sensitivity than dermoscopy and is especially useful in cases of suspected late recurrence. Further studies are needed to validate ongoing tumor free survival following this combined nonsurgical approach in the treatment of nBCC.

Background and Objectives: Warts are benign lesions of viral etiology characterized by a hyperkeratotic appearance tending to spread across the skin surface. Various treatments have been proposed to manage this condition, such as acids, imiquimod, photodynamic therapy, cryotherapy, and various lasers. Materials and Methods: In this paper, we describe a combination protocol using CO2 laser prior to Nd:YAG laser for lesions interesting the palmoplantar areas or dye laser for lesions on other skin surfaces in the management of non-facial warts resistant to traditional therapies. In total, 34 patients with 103 warts suffering from wart infection resistant to traditional therapies treated from 1 January 2019 to 1 June 2020 were retrospectively enrolled at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). Two dermatologists measured clinical results, classifying lesions with complete resolution, partial resolution, or non-responding. Patients at four months follow-up were asked to evaluate their degree of satisfaction with a visual analog scale (VAS). Results: Almost all patients reported the complete resolution of lesions, with no patient reporting scarring. Five patients reported hypopigmentation in the treated areas. The mean satisfaction level was high. Only three patients experienced a relapse of the condition. Conclusions: Using a vascular laser following a CO2 superficial ablation of warts may help reduce the risk of scarring and decrease the incidence of relapses for lesions resistant to traditional therapies. Therefore, more extensive studies will be necessary to confirm the obtained results.

Background and Objectives: Hair removal is a common cosmetic problem interesting more and more patients nowadays. Various laser treatments are currently available. Alexandrite and Nd:YAG laser are the most effective procedures in lighter and darker skin phototypes, respectively. Materials and Methods: A total of 40 patients seeking hair removal in one or more body areas with skin phototypes 2-6 was recruited to perform this study. Patients were divided into two groups. One group was treated with the standard Nd:YAG hair removal procedure, while the other group was treated with a new "in motion" Nd:YAG technology. Results and hair removal rates were evaluated six months after the last treatment. Results: Out of 40 patients treated, all patients experienced hair reduction. No statistically significant difference in hair removal was noted between the two groups; however, a statistically significant reduction in pain during the procedure was observed in the group treated with the "in motion" technique. Conclusions: While traditional and "in motion" Nd:YAG techniques have similar result outcomes in hair removal, the "in motion" technology seems to guarantee a better safety profile compared with the traditional technique. A more extensive clinical study will be necessary to confirm our study's results.

Background and objectives: Facial telangiectasias are dilated blood vessels that can represent a cosmetic issue for patients. They may be associated with other conditions, such as rosacea. Laser and light treatments are nowadays becoming a cornerstone in the management of these lesions. Materials and Methods: In total, 68 patients seeking medical treatment for facial telangiectasias were enrolled from 1 March 2019 to 1 March 2020 at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). A protocol consisting of a 1064 Nd:YAG laser for darker blue telangiectasias and 532 nm Nd:YAG for red lesions followed by intense pulsed light with an optimized spectrum for vascular lesion 3 weeks after the first procedure was proposed. A three-month follow-up visit assessed patient's satisfaction using a visual analog scale (VAS). Two dermatologists measured clinical results using a 4-point scale, comparing pictures before treatment and at follow-up. Results: A total of 68 patients (32 males and 36 females) completed the study, performing all requested treatments. No severe side effects were reported. Patient satisfaction was very high (8.15 ± 1.05 out of a 10-point VAS scale), as well as dermatologists' clinical evaluations (2.19 ± 0.74 out of 3). Conclusions: The combination of vascular lasers and Vascular Intense Pulsed Light acting specifically on small blood vessels may help to improve the aesthetic outcome, reducing side effects. A prospective study with a larger number of participants will be necessary to confirm this study's findings.

INTRODUCTION: Hand eczema (HE) is a prevalent inflammatory skin condition, impacting 15-20% of individuals, with a notable incidence rate of approximately 7.3 cases per 1000 person/years. This condition exhibits significant gender-based variability, with a higher prevalence in females. The clinical presentation of HE is characterized by pruritic erythematous, edematous, weeping plaques, vesicles, and/or bullae, showcasing considerable heterogeneity. EVIDENCE ACQUISITION: A literature search was conducted across multiple databases, including Medline, Pubmed, Scopus, and the Cochrane Library. The search was conducted using the following key words and medical subject heading (MeSH) terms: "hand," "eczema," "dermatitis," "dermoscopy," and "histology," employing the Boolean term "AND" to combine the research terms for optimal search precision. PRISMA algorithm has been used for article screening. The search scope included manuscripts published up to October 1, 2023. EVIDENCE SYNTHESIS: Up to 50% of HE cases are associated with atopic dermatitis, emphasizing the complex interplay between various dermatological conditions. Common subtypes of HE include irritant contact dermatitis (ICD), allergic contact dermatitis (ACD), atopic hand eczema (AHE), and protein contact dermatitis/contact urticaria (PCD). The chronic nature of HE presents a substantial management challenge, often underestimated, leading to delayed treatment and potential progression to chronic hand eczema (CHE). Beyond individual health implications, HE exerts a profound impact on occupational, domestic, social, and psychological aspects, establishing itself as the most prevalent occupation-related skin disease. This paper seeks to establish a comprehensive classification system for HE, integrating clinical, dermoscopic, and histological elements. Dermoscopy, specifically, proves instrumental in distinguishing HE from palmar psoriasis, revealing characteristic features such as yellow scales and irregular vessels. Histopathological findings underscore the dynamic changes observed from acute to chronic stages, while challenges in differentiating hyperkeratotic HE from psoriasis underscore the necessity for a holistic diagnostic approach. CONCLUSIONS: Accurate diagnosis and effective management of HE necessitate a holistic perspective that recognizes the inherent complexities of this inflammatory skin disease. By providing a multidimensional classification system, incorporating clinical, dermoscopic, and histological parameters, this paper aimed to contribute to a more nuanced understanding of HE and facilitate improved approaches to its diagnosis and treatment.
RESUMO
BACKGROUND: Tirbanibulin 1% ointment is approved for the field treatment of Olsen grade I actinic keratoses (AKs) of the face and scalp. METHODS: We performed a multicenter retrospective study involving 15 dermatologic units in Italy to investigate the efficacy and tolerability of tirbanibulin in a real-life setting. 250 patients were enrolled. Tirbanibulin, 1% ointment, was applied daily for five consecutive days. The efficacy of treatment was measured with modifications of the Actinic Keratosis Area and Severity Index (AKASI). A satisfactory response was defined by complete (100% reduction in the number of lesions) or partial clearance (75-99%) of treated AKs. RESULTS: Overall, the AKASI score was significantly reduced in the studied population (mean, from 4.1 ± 2.7 to 1.4 ± 1.5; P < 0.001). A satisfactory response was observed in 222 (88.8%) cases. The proportion of satisfactory responses was higher when follow-up was performed after 8 weeks (34/35, 97.1%). The reduction in AKASI was significant in patients with Olsen grade II or III lesions (from 5.3 ± 2.8 to 1.6 ± 1.6; P < 0.001). A satisfactory response was observed in 91/104 (87.5%) cases. AKASI reduction was also significant in patients with trunk or limb AKs (from 7.0 ± 1.3 to 2.0 ± 1.6; P = 0.018) since a satisfactory response was observed in 7/8 (87.5%) cases. Tirbanibulin was well tolerated; all adverse events (AEs) included transient local reactions at the site of treatment. Overall, 231 patients had at least one AE. Only 7 (2.8%) grade 4 AEs were recorded. CONCLUSION: Our retrospective study confirmed that tirbanibulin 1% ointment is effective and well tolerated in a real-life setting and is also promising for Olsen grade II and grade III AKs and AKs localized on difficult-to-treat areas.
RESUMO
Tattoo removal is a well-established procedure in dermatology. Lasers represent the gold standard in the management of this condition nowadays. In this study, we report our experience on the use of a Q-switched nanosecond source. A total of 52 patients were consecutively enrolled in performing tattoo removal at Magna Graecia University of Catanzaro and Tor Vergata University of Rome. Black and blue tattoos were treated with a 1064 nm laser, with a pulse duration of 6 ns and a fluence up to 10 J/cm2, while colored tattoos were treated with sessions of 532 nm laser, with a pulse duration of 6 ns and a fluence up to 5 J/cm2. Up to nine treatments with a minimum interval of 8 weeks between each session were performed. A six-month follow-up visit assessed patient satisfaction (Visual Analogue Scale). Overall clinical result was assessed with a clinical evaluation by two blinded dermatologists using a 5-point scale, comparing pictures before treatment and at follow up. A total of 52 patients were included and analyzed: 30 females (57.7%) and 22 males (42.3%). Mean age was 43.7 ± 12.7 years. According to Fitzpatrick's skin classification, 16 individuals (30.8%) were type II, 15 (28.8%) were type III, and 21 (40.4%) were type IV. Most of the treated tattoos were carried out by professionals. The mean number of sessions required to obtain a result was 4.6 ± 2.5, and the final tattoo removal rate was 60% or higher, with 51.9% of the patients reporting highest satisfaction scores Q-Switched 1064/532 nm laser may be considered today as the gold-standard treatment for tattoo removal. Our results confirm literature findings of the safety and effectiveness of these devices.
