Comparison of Ophthalmologists versus Dermatologists for the Diagnosis and Management of Periorbital Atypical Pigmented Skin Lesions. J Clin Med 2024; 13:4787. [PMID: 39200928 PMCID: PMC11355784 DOI: 10.3390/jcm13164787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2024] [Revised: 08/07/2024] [Accepted: 08/09/2024] [Indexed: 09/02/2024] Open
Abstract
Background/Objectives: Lentigo maligna (LM) and lentigo maligna melanoma (LMM) are significant subtypes of melanoma, with an annual incidence of 1.37 per 100,000 people in the U.S. These skin tumors, often found in photo-exposed areas such as the face, are frequently misdiagnosed, leading to delayed treatment or unnecessary excisions, especially in the elderly. Facial melanocytic skin tumors (lentigo maligna-LM/lentigo maligna melanoma-LMM) and their simulators (solar lentigo, pigmented actinic keratosis, seborrheic keratosis and lichen planus-like keratosis) often affect the periocular region. Thus, their diagnosis and management can involve different medical figures, mainly dermatologists and ophthalmologists. This study aimed to evaluate the ability of ophthalmologists to diagnose and manage pigmented skin lesions of the periorbital area. Methods: A multicentric, retrospective, cross-sectional study on a dataset of 79 periorbital pigmented skin lesions with both clinical and dermoscopic images was selected. The images were reviewed by six ophthalmologists and two dermatologists. Descriptive statistics were carried out, and the accuracy, sensitivity, and specificity, with their 95% confidence interval (95% CI), were estimated. Results: Ophthalmologists achieved a diagnostic accuracy of 63.50% (95% CI: 58.99-67.85%), while dermatologists achieved 66.50% (95% CI: 58.5-73.8). The sensitivity was lower for ophthalmologists in respect to dermatologists, 33.3% vs. 46.9%, respectively. Concerning the case difficulty rating, ophthalmologists rated as "difficult" 84% of cases, while for dermatologists, it was about 30%. Management was also consistently different, with a "biopsy" decision being suggested in 25.5% of malignant lesions by ophthalmologists compared with 50% of dermatologists. Conclusions: Ophthalmologists revealed a good diagnostic potential in the identification of periorbital LMs/LMMs. Given progressive population ageing and the parallel increase in facial/periorbital skin tumors, the opportunity to train new generations of ophthalmologists in the early diagnosis of these neoformations should be considered in the next future, also taking into account the surgical difficulty/complexity of this peculiar facial area.

Abstract
BACKGROUND Skin cancer incidence increases globally, requiring effective preventive measures and evidence-based treatment strategies. Current guidelines advocate for surgical excision as a first-line treatment for most early skin cancers. The study investigated practices regarding changing scalpel blades when excising multiple skin lesions in the same patient during the same visit (CSB) and explored how beliefs about iatrogenic seeding influence individual norms of practice. METHODS A multidisciplinary survey was conducted among 173 medical specialists involved in skin cancer care. Participants provided demographic information, years of experience, and practices regarding CSB in four clinical scenarios (first excised tumor: basal cell carcinoma, squamous cell carcinoma, melanoma suspect, and evident melanoma). Practice variations based on specialty, experience, and beliefs about seeding risk were statistically assessed. RESULTS Surgeons exhibited a significantly higher tendency to change blades compared to non-surgeons across all diagnoses. Iatrogenic seeding (56.52%) and clinical training (18.84%) were the main reasons provided for CSB. Beliefs about seeding risk did not differ significantly between specialties. CONCLUSIONS Although the practice of CSB lacks strong scientific rationale, the approach to this practice significantly varies among different medical specialties. Healthcare professionals should critically evaluate and standardize evidence-based practices to ensure optimal patient care and mitigate potential harm.

Abstract
BACKGROUND Despite the advancement of reconstructive surgical techniques, facial defect reconstruction has been always very challenging, aesthetic satisfaction has often been difficult to achieve due to the unique characteristics and complexity of the facial tissue. There have been various options regarding reconstruction and compensation of soft tissue loss all over the body rather than the face. Regardless of whether skin grafts, local flaps, and free flaps were used in the reconstruction process, each of them has its limitations. Beginning with skin grafts results could not always be satisfactory due to contracture, color, and lack of texture Additionally, local flaps have limitations due to mobility and the availability of overlapping skin and tissue, as well as the bulkiness of the pedicle which may need a second staged surgery and lately the difficulty of the free flaps and being a major surgery. RESULTS Patients ages ranged between 23 and 77 years old, with a mean age of 58.33 ± 12.47. As regards the patients' sex, 63.3% of our patients were males and 36.7% were females. Co-morbidities were found in 60% of cases (DM 23.3%, HTN 20%, HCV 3.3%, cardiac 3.3%). Most flaps were facial artery perforator flaps 53.3%, then transverse facial artery 26.7%, superficial temporal artery 10%, angular artery 6.7%, and supra-trochlear artery 3.3%. Twenty-ix cases representing 86.7% of cases went uneventful, while complications showed in 4 cases representing 13.3% of cases, 1 case (3.3%) showed venous congestion that was relieved within 24 h after 2 suture releases, another case (3.3%) showed wound dehiscence that was improved after 2 days with regular dressings, the third patient (3.3%) had recurrence after 4 months that was treated by excision and grafting, while last patient (3.3%) had inadequate excision that was treated by radiotherapy. No bleeding or infection occurred. Also, we observed no correlation between flap length and complications. As regards the functional point of view, all patients showed no functional impairment at the donor site, and only one case showed functional impairment at the recipient site. As regards patient satisfaction, all 30 patients achieved positive satisfaction scores using the Likert scale, 18 cases were satisfied, and 12 cases were very satisfied. CONCLUSION The use of perforator-based flaps can provide a more effective and aesthetically pleasing solution for the reconstruction of small to moderate facial defects, provided that a reliable Perforator is accurately identified and executed by an experienced surgeon.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024; 125:101726. [PMID: 38056693 DOI: 10.1016/j.jormas.2023.101726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 12/02/2023] [Accepted: 12/03/2023] [Indexed: 12/08/2023]
Abstract
INTRODUCTION Approximately 80,000 cases of skin cancer are diagnosed annually in France. The management of these cancers can occur in both university hospital centers and ambulatory surgery centers. Limited data exist regarding the epidemiology of cutaneous cancers treated through ambulatory surgery centers. The objective of our study is to describe the epidemiological characteristics of cutaneous cancers managed in a tertiary ambulatory surgery center. METHODS This is a retrospective, single-center observational study. The included patients were those who underwent surgical excision of one or more skin cancers within the maxillofacial department of a tertiary ambulatory surgery center. Clinical, therapeutic, histopathological, and follow-up data (additional surgery if margins were not clear, progression, recurrence, second cancer…) were collected. RESULTS Among the n = 1931 patients operated for a head and neck skin tumor from September 2018 to July 2022, n = 426 (22 %) were diagnosed with cancer upon histological analysis. The median age was 76 years (31-100), with a male-to-female ratio of 1/1. The most frequent locations were the nose (23 %) and cheek (20 %). Ten percent of patients had dual-site skin cancer at initial diagnosis. The most common histological types were basal cell carcinoma (77 %) and squamous cell carcinoma (18 %). Surgical treatment primarily consisted of "excision-reconstruction with local flap" (51 %) or "excision-suture" (34 %). Resection margins were mostly clear (65 %), and only six patients (2 %) experienced local recurrence or progression during follow-up. CONCLUSIONS Skin cancers are prevalent in ambulatory practice. Surgical treatment allows for effective control of the cancer. Photoprotection, particularly in immunocompromised patients, remains crucial for prevention.

Abstract
BACKGROUND The nose is a common site for the development of skin cancers. Mohs micrographic surgery (MMS) is a highly curative treatment for skin cancer of the nose. Reconstruction of MMS defects on the nose, especially on the distal aspect, can be challenging given the proximity of multiple subunits and limited adjacent tissue reservoirs. Our goal was to describe our experience using a nasal tip rotation flap (NTRF) for MMS defects on the distal nose. METHODS A retrospective review of all MMS cases at multiple institutions between June 2018 and June 2022 was undertaken. Cases that used an NTRF to repair the MMS defect(s) were selected, and data were collected on patient demographics, tumor type, anatomical location of the tumor, preoperative and postoperative size, number of stages needed to clear the tumor, repair dimensions, and any postoperative complications. RESULTS A total of 66 cases that utilized an NTRF for reconstruction were included. The mean preoperative tumor size was 0.8 cm (range: 0.3-1.6 cm), and the mean defect size was 1.2 cm (range: 0.7-1.9 cm). The defects were most commonly on the nasal tip. There were no significant complications observed. CONCLUSIONS The nasal tip rotation flap is a reliable reconstruction option for MMS defects of the distal nose. This flap can be used for defects that involve the nasal tip, soft triangle, and/or portions of the ala, including the alar rim.

Abstract
The reliability of local intranasal flaps speaks to the robust vascularity of the nose, which these flaps are based on. The goals for lining replacement, as in any other area of head and neck reconstruction, is to use tissue that best matches the qualities of what is being replaced. The goal of this review is to describe the extent to which local tissues can be used and when to consider regional flaps when the extent of a local flap will not provide enough coverage.

Abstract
Skin cancer (SC) poses a global threat to the healthcare system and is expected to increase significantly over the next two decades if not diagnosed at an early stage. Early diagnosis is crucial for successful treatment, as the disease becomes more challenging to cure as it progresses. However, identifying new drugs, achieving clinical success, and overcoming drug resistance remain significant challenges. To overcome these obstacles and provide effective treatment, it is crucial to understand the causes of skin cancer, how cells grow and divide, factors that affect cell growth, and how drug resistance occurs. In this review, we have explained various therapeutic approaches for SC treatment via ligands, targeted photosensitizers, natural and synthetic drugs for the treatment of SC, an epigenetic approach for management of melanoma, photodynamic therapy, and targeted therapy for BRAF-mutated melanoma. This article also provides a detailed summary of the various natural drugs that are effective in managing melanoma and reducing the occurrence of skin cancer at early stages and focuses on the current status and future prospects of various therapies available for the management of skin cancer.

Abstract
OBJECTIVE Cutaneous Squamous Cell Carcinoma (cSCC), a tumor with a significantly increasing incidence, is mostly diagnosed in the head region, where tumors have a worse prognosis and a higher risk of metastases. The presence of metastases reduces specific five-year survival from 99% to 50%. As the risk of occult metastases does not exceed 10%, elective dissection of the tributary parotid and neck lymph nodes is not recommended. METHODS We retrospectively analyzed a group of 12 patients with cSCC of the head after elective dissections of regional (parotid and cervical) nodes by means of superficial parotidectomy and selective neck dissection. RESULTS We diagnosed occult metastases neither in the cervical nor parotid nodes in any patient. None were diagnosed as a regional recurrence during the follow-up period. CONCLUCION Our negative opinion on elective parotidectomy and neck dissection in cSCC of the head is in agreement with the majority of published studies. These elective procedures are not indicated even for tumors showing the presence of known (clinical and histological) risk factors for lymphogenic spread, as their positive predictive value is too low. Elective parotidectomy is individually considered as safe deep surgical margin. If elective parotidectomy is planned it should include only the superficial lobe. Completion parotidectomy and elective neck dissection are done in rare cases of histologically confirmed parotid metastasis in the parotid specimen. Preoperatively diagnosed parotid metastases without neck involvement are sent for total parotidectomy and elective selective neck dissection. Cases of clinically evident neck metastasis with no parotid involvement, are referred for comprehensive neck dissection and elective superficial parotidectomy. The treatment of concurrent parotid and cervical metastases includes total conservative parotidectomy and comprehensive neck dissection. LEVEL OF EVIDENCE How common is the problem? Step 4 (Case-series) Is this diagnostic or monitoring test accurate? (Diagnosis) Step 4 (poor or non-independent reference standard) What will happen if we do not add a therapy? (Prognosis) Step 4 (Case-series) Does this intervention help? (Treatment Benefits) Step 4 (Case-series) What are the COMMON harms? (Treatment Harms) Step 4 (Case-series) What are the RARE harms? (Treatment Harms) Step 4 (Case-series) Is this (early detection) test worthwhile? (Screening) Step 4 (Case-series).

Abstract
<b><br>Introduction:</b> Skin cancers constitute a group of medical disorders remaining a field of interest for surgeons and dermatologists. Currently, this group is typically divided into malignant melanoma (MM) and keratinocyte cancers (KC).</br> <b><br>Aim:</b> The aim of this study is to analyze the cases of skin cancers treated in the Department of Plastic, Reconstructive, and Aesthetic Surgery in Lodz (Poland) during the COVID-19 pandemic (from 2020 to 2022) and then compare the results with the ones from the pre-pandemic period (from 2017 to 2019).</br> <b><br>Material and methods:</b> An analysis of histopathological files from the period between 2020 and 2022 was performed. It was based on the following criteria: sex, age, type of skin cancer, subtype of basal cell carcinoma (BCC), location, and dimensions of the tumor. The study sample consisted of 225 patients presenting 241 cases of skin cancers. There were 74 men and 151 women, with the mean age being 71.7.</br> <b><br>Results:</b> The most common skin cancer was BCC (175 cases, 72.6%) followed by SCC (59 cases, 24.5%), melanoma (5 cases, 2.1%), and other (2 cases, 0.8% - angiosarcoma and sweat gland carcinoma).</br> <b><br>Conclusions:</b> A marked reduction in the number of skin cancers detected during the pandemic period was reported on. Delay in the surgical treatment of skin tumors does not seem to affect the size of the removed lesion. Some models predicting that tumors would be larger after the confinement period are not applicable in reality. However, further investigations with larger samples from multiple centers are needed to confirm these findings and to work out standards on how to deal with healthcare crises in the future.</br>.

Fijałkowska M, Koziej M, Antoszewski B, Sitek A. Correlations between antimicrobial peptides and spectrophotometric skin color parameters in patients with basal cell carcinoma. J Cancer Res Clin Oncol 2023; 149:5697-5704. [PMID: 36542158 PMCID: PMC10356866 DOI: 10.1007/s00432-022-04530-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Antimicrobial peptides (AMPs) are active molecules in the human innate immune system, that participate in host defense and regulate the inflammation process. Previous reports have confirmed that antimicrobial peptides play a critical role in carcinogenesis. OBJECTIVE The present study aimed to evaluate the correlations between plasma concentrations of AMPs and spectrophotometric parameters of skin color in patients with basal cell carcinoma and compare the results with those of healthy controls. METHODS The plasma concentrations of cathelicidin and beta-defensin-2 in 100 patients (50 with skin cancer and 50 healthy control subjects) were measured, and skin color parameters were tested using a DermaSpectrophotometer. RESULTS In patients with basal cell carcinoma, the concentrations of cathelicidin and beta-defensin-2 were significantly higher than those in healthy controls. In healthy control patients, when erythema increases, the levels of cathelicidin and beta-defensin-2 also increase. The direction of the relationship is opposite in people with basal cell carcinoma-the concentration of antimicrobial peptides decreases and the level of erythema increases. CONCLUSION A significantly higher level of plasma concentrations of cathelicidin and HBD-2 are correspondent to the presence of basal cell carcinoma. Skin cancer modifies the relationship between intensity of skin erythema and the levels of cathelicidin and HBD-2. This can be related to inadequate immunological response in patients with skin cancers. New direction of research may be pioneered in searching for cytokine or mast cells disorders.

Front Oncol 2023; 13:1166877. [PMID: 37519813 PMCID: PMC10374428 DOI: 10.3389/fonc.2023.1166877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 06/23/2023] [Indexed: 08/01/2023] Open
Abstract
Objective To investigate risk factors for advanced melanoma over 50 years of age and to develop and validate a new line chart and classification system. Methods The SEER database was screened for patients diagnosed with advanced melanoma from 2010 to 2019 and Cox regression analysis was applied to select variables affecting patient prognosis. The area under curve (AUC), relative operating characteristic curve (ROC), Consistency index (C-index), decision curve analysis (DCA), and survival calibration curves were used to verify the accuracy and utility of the model and to compare it with traditional AJCC tumor staging. The Kaplan-Meier curve was applied to compare the risk stratification between the model and traditional AJCC tumor staging. Results A total of 5166 patients were included in the study. Surgery, age, gender, tumor thickness, ulceration, the number of primary melanomas, M stage and N stage were the independent prognostic factors of CSS in patients with advanced melanoma (P<0.05). The predictive nomogram model was constructed and validated. The C-index values obtained from the training and validation cohorts were 0.732 (95%CI: 0.717-0.742) and 0.741 (95%CI: 0.732-0.751). Based on the observation and analysis results of the ROC curve, survival calibration curve, NRI, and IDI, the constructed prognosis model can accurately predict the prognosis of advanced melanoma and performs well in internal verification. The DCA curve verifies the practicability of the model. Compared with the traditional AJCC staging, the risk stratification in the model has a better identification ability for patients in different risk groups. Conclusion The nomogram of advanced melanoma and the new classification system were successfully established and verified, which can provide a practical tool for individualized clinical management of patients.

Abstract
INTRODUCTION Cancer patients and survivors have a high risk of developing additional malignancies. Patients who undergo melanoma excision often have sun-damaged skin and are predisposed to concurrent and subsequent skin cancers. The unexpected finding of an incidental cancer on melanoma wide excisions can require further surgery and delays adjuvant treatment. We aimed to determine the incidence and risk factors for incidental skin cancers in patients who had surgical excision of melanoma. METHODS Our single-center retrospective study analyzed all patients diagnosed with primary melanoma at our institution from July 1, 2019 through June 30, 2020. We included patients with localized cutaneous melanoma who underwent surgical excision and had relevant pathology data available. Descriptive statistics and univariate analyses were performed on the demographic, clinical, and pathological data collected. We analyzed differences between the groups with and without incidental cancer to ascertain risk factors using chi-squared tests and Wilcoxon rank sum tests. Dunn's tests with Bonferroni correction were performed for multiple pairwise comparisons. RESULTS There were 642 patients who met the criteria for inclusion, of whom 13 (2.0%) had incidental cancers identified on a pathologic assessment. Six (46%) had incidental squamous cell carcinoma and seven (54%) had basal cell carcinoma. With regard to management of incidental cancer, three (23%) patients required additional surgery for margin re-excision. Risk factors for incidental cancers in melanoma excision included older age (median 79 versus 62 y, P < 0.001), male sex (P = 0.042), and primary tumor location in the head/neck region relative to trunk (P < 0.01) or extremity (P < 0.01) primary sites. CONCLUSIONS Although the frequency of incidental findings on melanoma excision is low, certain patients are at a greater risk including older male individuals with head/neck melanomas. These findings can be used to improve preoperative counseling of at-risk patients when melanoma excision is planned.

Abstract
Background and Objectives: An increasing incidence of non-melanoma skin cancer (NMSC) is noted, as well as an increasing cost of the treatment, with NMSC becoming a public health problem. We aimed to investigate the prevalence and treatment costs of surgically treated NMSC from the Oral and Maxillofacial Surgery Department of Cluj-Napoca County Hospital. Materials and Methods: We retrospectively analyzed the clinical data and the charge data of hospitalization from the informatic system of Cluj-Napoca County Hospital. All patients benefited from standard surgical excision with the reconstruction of the post-excisional defect. A statistical analysis of the costs related to the patients' features, period and conditions of hospitalization, materials, medication, and paraclinical investigations was performed. Results: Between 2015 and 2019, 133 patients with NMSC were addressed to our department, with basal cell carcinoma (BCC) being four-fold higher than squamous cell carcinoma (SCC). Most NMSC cases were diagnosed in stage I or II, and they benefited from local reconstruction. The treatment costs progressively increased in the last five years, reaching a total cost of EUR ~13.000 in 2019. The treatment cost per episode was higher for SCC compared to BCC, while the total cost of treatment in 5 years was higher for BCC. Low income, immunosuppression, comorbidities, flap reconstruction option, long-lasting surgery, and prolonged hospitalization were associated with an increased cost of the treatment. Conclusion: The prevalence and treatment cost of surgically treated NMSC of the head and neck region increased in the last five years, with high-cost drivers being related to patients and treatment options.

Abstract
Skin cancer, including malignant melanoma (MM) and keratinocyte carcinoma (KC), historically named non-melanoma skin cancers (NMSC), represents the most common type of cancer among the white skin population. Despite decades of clinical research, the incidence rate of melanoma is increasing globally. Therefore, a better understanding of disease pathogenesis and resistance mechanisms is considered vital to accomplish early diagnosis and satisfactory control. The "Omics" field has recently gained attention, as it can help in identifying and exploring metabolites and metabolic pathways that assist cancer cells in proliferation, which can be further utilized to improve the diagnosis and treatment of skin cancer. Although skin tissues contain diverse metabolic enzymes, it remains challenging to fully characterize these metabolites. Metabolomics is a powerful omics technique that allows us to measure and compare a vast array of metabolites in a biological sample. This technology enables us to study the dermal metabolic effects and get a clear explanation of the pathogenesis of skin diseases. The purpose of this literature review is to illustrate how metabolomics technology can be used to evaluate the metabolic profile of human skin cancer, using a variety of analytical platforms including gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and nuclear magnetic resonance (NMR). Data collection has not been based on any analytical method.

Pharmaco-Toxicological Assessment of the Combined Cytotoxic Effects of Digoxin and Betulinic Acid in Melanoma Cells. LIFE (BASEL, SWITZERLAND) 2022; 12:life12111855. [PMID: 36430989 PMCID: PMC9694166 DOI: 10.3390/life12111855] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 11/07/2022] [Accepted: 11/09/2022] [Indexed: 11/16/2022]
Abstract
Betulinic acid, a small molecule from pentacyclic triterpenes class, has been widely studied for its antitumor activity, revealing that it induces the apoptosis of tumor cells in a selective manner. In recent years, digoxin, a cardiac glycoside found particularly in the plant species Digitalis lanata, has drawn interest for its potential antitumor properties. The present study was designed to evaluate the antimelanoma potential of betulinic acid (BA), digoxin (DG), and their association (DG + BA). In vitro assessments were performed 24 h post-treatment on two human melanoma cell lines (SK-Mel-28 and RPMI-7951). In addition, the potential irritant effects of the test samples were evaluated using the chorioallantoic membrane of hen's eggs. BA and DG exhibit a concentration-dependent cytotoxic activity, with the combination of the two having a more marked effect on the decrease in cell viability (~17% for SK-Mel-28 cells and ~23% for RPMI-7951 cells). Further, morphological changes (rounding of the cells and their separation from the plaque) and alterations in the nucleus and actin fibers (condensation of chromatin and actin fibers, formation of apoptotic bodies) were observed, indicating an apoptotic-like process. Moreover, no irritating effects were observed in ovo. As a result, DG + BA acid may have synergistic potential in the antitumor treatment of melanoma, but future studies are needed in order to clarify the biological mechanisms involved.

Abstract
Skin cancer is among the most prevalent and life-threatening forms of cancer that occur worldwide. Traditional methods of skin cancer detection need an in-depth physical examination by a medical professional, which is time-consuming in some cases. Recently, computer-aided medical diagnostic systems have gained popularity due to their effectiveness and efficiency. These systems can assist dermatologists in the early detection of skin cancer, which can be lifesaving. In this paper, the pre-trained MobileNetV2 and DenseNet201 deep learning models are modified by adding additional convolution layers to effectively detect skin cancer. Specifically, for both models, the modification includes stacking three convolutional layers at the end of both the models. A thorough comparison proves that the modified models show their superiority over the original pre-trained MobileNetV2 and DenseNet201 models. The proposed method can detect both benign and malignant classes. The results indicate that the proposed Modified DenseNet201 model achieves 95.50% accuracy and state-of-the-art performance when compared with other techniques present in the literature. In addition, the sensitivity and specificity of the Modified DenseNet201 model are 93.96% and 97.03%, respectively.

Abstract
Skin cancer, which includes the most frequent malignant non-melanoma carcinomas (basal cell carcinoma, BCC, and squamous cell carcinoma, SCC), along with the difficult to treat cutaneous melanoma (CM), pose important worldwide issues for the health care system. Despite the improved anti-cancer armamentarium and the latest scientific achievements, many skin cancer patients fail to respond to therapies, due to the remarkable heterogeneity of cutaneous tumors, calling for even more sophisticated biomarker discovery and patient monitoring approaches. Droplet digital polymerase chain reaction (ddPCR), a robust method for detecting and quantifying low-abundance nucleic acids, has recently emerged as a powerful technology for skin cancer analysis in tissue and liquid biopsies (LBs). The ddPCR method, being capable of analyzing various biological samples, has proved to be efficient in studying variations in gene sequences, including copy number variations (CNVs) and point mutations, DNA methylation, circulatory miRNome, and transcriptome dynamics. Moreover, ddPCR can be designed as a dynamic platform for individualized cancer detection and monitoring therapy efficacy. Here, we present the latest scientific studies applying ddPCR in dermato-oncology, highlighting the potential of this technology for skin cancer biomarker discovery and validation in the context of personalized medicine. The benefits and challenges associated with ddPCR implementation in the clinical setting, mainly when analyzing LBs, are also discussed.

Abstract
Skin cancer is the most common type of carcinoma diagnosed worldwide, with significant morbidity and mortality rates among Caucasians, in particular basal cell carcinoma (BCC). The main risk factors of BCC are well-identified, and there are many chemotherapeutic drugs available for its treatment. The effectiveness of therapeutic options is governed by several factors, including the location of the tumor, its size, and the presence of metastases (although rare for BCC). However, available treatments are based on non-targeted approaches, which encounter a significant risk of systemic toxicity in several organs. Site-specific chemotherapy for BCC has been proposed via the loading of anticancer drugs into nanoparticles. Among various types of nanoparticles, in this review, we focus on potential new regimens for the treatment of BCC using classical anticancer drugs loaded into novel lipid nanoparticles. To meet patient aesthetic expectations and enhance the effectiveness of basal cell carcinoma treatment, new therapeutic topical strategies are discussed, despite a limited number of reports available in the literature.

Assessment of the Predictive Value of Spectrophotometric Skin Color Parameters and Environmental and Behavioral Factors in Estimating the Risk of Skin Cancer: A Case-Control Study.

Abstract
Keratinocyte carcinomas are the most common cancers with different etiological risk factors. The aim of this study was to assess the predictive value of spectrophotometric parameters of skin color in correlation with environmental/behavioral factors to estimate the risk of skin cancer. The case-control study involved 389 patients. The analysis was performed on the training group to build a predictive model and on the testing group to check the quality of the designed model. Area under the curve based on the spectrophotometric skin parameters varied from 0.536 to 0.674. A statistically significant improvement of the area under curve was achieved by adding the number of sunburns for some models. The best single spectrophotometric measurement for estimating skin cancer is the skin melanin index measured on the arm or buttock. Spectrophotometric skin parameters are not very strong but are essential elements of models for estimating the risk of skin cancer. The most important environmental/behavioral factor seems to be the number of sunburns, but not the total exposure to ultraviolet radiation or usage of photoprotectors. Some other pigmentation predictors should be taken into account when creating new models, especially those that can be easily measured in objective and repeatable way. Spectrophotometric measurements can be employed as quick screening skin examination method.

Abstract
Populations with a relatively low concentration of melanin, e.g., inhabitants of Europe, North America, and Australia, are the most vulnerable to the harmful effects of UV radiation. Individuals with fair phototype are at greatest risk of developing skin cancer. Several neurological studies present that light skin may modify the risk of Alzheimer’s and Parkinson’s diseases. However, the relationship between migraine and skin pigmentation has not been investigated yet. The objective of this study is to provide evidence of the relationship between skin pigmentation and migraine prevalence in adults. We examined a group of 148 adults (33 men, 115 women) with migraine and a control group of 107 adults (43 men, 64 women). Parameters of skin pigmentation (melanin index, erythema index, CIElab, and RGB scales) were measured using a DSM II Cortex Technology dermospectrophotometer. Risk of migraine in lightly pigmented adults was elevated. Individuals with a low melanin index had over 3-fold increased risk of migraine (women: OR 3.53, men: OR 3.73). Fair phototype, which results from lightly pigmented skin, was associated with migraine prevalence. Migraineurs should take extra care to protect their skin from the negative effects of solar radiation.
