RESUMO
BACKGROUND: Mohs micrographic surgery (MMS) is a promising treatment modality for melanoma in situ (MIS). However, variations in surgical technique limit the generalizability of existing data and may impede future study of MMS in clinical trials. METHODS: A modified Delphi method was selected to establish consensus on optimal MMS techniques for treating MIS in future clinical trials. The Delphi method was selected due to the limited current data, the wide range of techniques used in the field, and the intention to establish a standardized technique for future clinical trials. A literature review and interviews with experienced MMS surgeons were performed to identify dimensions of the MMS technique for MIS that (1) likely impacted costs or outcomes of the procedure, and (2) showed significant variability between surgeons. A total of 8 dimensions of technical variation were selected. The Delphi process consisted of 2 rounds of voting and commentary, during which 44 expert Mohs surgeons across the United States rated their agreement with specific recommendations using a Likert scale. RESULTS: Five of eight recommendations achieved consensus in Round 1. All 3 of the remaining recommendations achieved consensus in Round 2. Techniques achieving consensus in Round 1 included the use of a starting peripheral margin of ≤5 mm, application of immunohistochemistry, frozen tissue processing, and resecting to the depth of subcutaneous fat. Consensus on the use of Wood's lamp, dermatoscope, and negative tissue controls was established in Round 2. CONCLUSIONS: This study generated 8 consensus recommendations intended to offer guidance for Mohs surgeons treating MIS. The adoption of these recommendations will promote standardization to facilitate comparisons of aggregate data in multicenter clinical trials.
RESUMO
The International Immunosuppression and Transplant Skin Cancer Collaborative (ITSCC) and its European counterpart, Skin Care in Organ Transplant Patients-Europe (SCOPE) are comprised of physicians, surgeons, and scientist who perform integrative collaborative research focused on cutaneous malignancies that arise in solid organ transplant recipients (SOTR) and patients with other forms of long-term immunosuppression. In October 2022, ITSCC held its biennial 4-day scientific symposium in Essex, Massachusetts. This meeting was attended by members of both ITSCC and SCOPE and consisted of specialists including Mohs micrographic and dermatologic oncology surgeons, medical dermatologists, transplant dermatologists, transplant surgeons, and transplant physicians. During this symposium scientific workshop groups focusing on consensus standards for case reporting of retrospective series for invasive squamous cell carcinoma (SCC), defining immunosuppressed patient status for cohort reporting, development of multi-institutional registry for reporting rare tumors, and development of a KERACON clinical trial of interventions after a SOTRs' first cutaneous SCC were developed. The majority of the symposium focused on presentation of the most up to date research in cutaneous malignancy in SOTR and immunosuppressed patients with specific focus on chemoprevention, immunosuppression regimens, immunotherapy in SOTRs, spatial transcriptomics, and the development of cutaneous tumor registries. Here, we present a summary of the most impactful scientific updates presented at the 2022 ITSCC symposium.

BACKGROUND: Clinical genetic tests are integral to healthcare decision-making. However, the unclear regulatory framework, especially regarding products that evade stringent FDA oversight, may compromise test validity and transparency. OBJECTIVE: To critically evaluate the DecisionDx® cutaneous squamous cell carcinoma test by Castle Biosciences for its dataset biases, gene panel selection, and reported accuracy metrics, providing insight into broader challenges in the clinical genetic testing landscape. METHODS: Independent analyses of the DecisionDx®-SCC 40-GEP test data from Castle Biosciences were conducted. These included comparisons to clinical genetic testing standards, analysis of prevalence metrics against national cSCC rates, gene ontology of 34 genes for cSCC associations, and evaluation of accuracy metrics. RESULTS: The DecisionDx®-SCC met 11 of 44 CDC's ACCE criteria for clinical genetic testing. Its dataset showed a metastasis prevalence higher than the national average. Out of 34 genes, 15 had known associations with cSCC. Inconsistencies in accuracy metrics presentation were noted, particularly in moderate and high-risk stratifications. CONCLUSION: Analysis of DecisionDx®-SCC indicates potential biases and ambiguities, exacerbated by differences between FDA and CLIA standards. This highlights the need for systematic validation and a unified regulatory approach, stressing the necessity for precise and dependable genetic testing in patient care.
RESUMO
Longer life expectancy and increasing keratinocyte carcinoma incidence contribute to an increase in geriatric patients presenting for dermatologic surgery. Unique considerations accompany geriatric patients including goals of care, physiologic changes in medication metabolism, cognitive decline, and frailty. Limited geriatric training in dermatology residency has created a knowledge gap and dermatologic surgeons should be familiar with challenges facing older patients to provide interventions more congruent with goals and avoid overtreatment. Frailty assessments including the Geriatric 8 and Karnofsky Performance Scale are efficient tools to identify patients who are at risk for poor outcomes and complications. When frail patients are identified, goals of care discussions can be aided using structured palliative care frameworks including the 4Ms, REMAP, and Serious Illness Conversation Guide. Most geriatric patients will tolerate standard of care treatments including invasive modalities like Mohs surgery and excision. However, for frail patients, non-standard treatments including topicals, energy-based devices, and intralesional chemotherapy may be appropriate options to limit patient morbidity while offering reasonable disease control.
RESUMO
Geriatric patients compose a growing proportion of the dermatologic surgical population. Dermatologists and dermatologic surgeons should be cognizant of the unique physiologic considerations that accompany this group to deliver highly effective care. The purpose of this article is to discuss the unique preoperative, intraoperative, and postoperative considerations geriatric patients present with to provide goal-concordant care. Preoperative considerations include medication optimization and anxiolysis. Intraoperative considerations such as fall-risk assessment and prevention, sundowning, familial support, and pharmacologic interactions will be discussed. Lastly, effective methods for optimizing post-operative wound care, home care, and follow up are reviewed.
RESUMO
BACKGROUND: Mohs micrographic surgery (MMS) is a technique that combines surgical excision and histologic evaluation to achieve higher cure rates for skin cancer than traditional surgical excision. Competing performance measures have fostered numerous histologic techniques for MMS. OBJECTIVE: To analyze differences in primary outcomes in the published literature regarding the technique of tissue processing and embedding during the MMS process. METHODS: A systematic review was performed of the published literature in MEDLINE, PubMed, Embase, and Cochrane library that included a description of the manipulation of tissue during the grossing and embedding steps of MMS. RESULTS: Inclusion criteria were met by 61 articles. Of these studies, the cure/recurrence rate was assessed in 1 article (1.6%), tissue conservation was assessed in 47 (77%), time-saving was assessed in 35 (57%), cost-saving was assessed in 6 (10%), and decreased artifact were assessed in 20 (33%). CONCLUSION: There is a lack of standardization for assessing clinical outcomes in the published literature regarding MMS process techniques. Cure is a critical outcome in studies comparing MMS processing methodologies.

BACKGROUND: Pain assessment plays an important role in dermatologic surgery. The numeric rating scale (NRS), visual analog scale (VAS), verbal rating scale (VRS), and Faces Pain Scale (FPS) are commonly used scales for pain measurement. Conflicting evidence exists regarding the use of each. Prompt pain recognition and treatment during procedures result in higher patient satisfaction. OBJECTIVE: Determine the most applicable scale for acute pain measurement in dermatologic surgery. MATERIALS AND METHODS: This systematic review was performed in accordance with PRISMA-Supplemental Digital Content 4, http://links.lww.com/DSS/A976 (PROSPERO; CRD42018091058). PubMed, Cochrane, EMBASE, Scopus, and Web of Science were searched between April 24, 2018, and May 06, 2018. The search query consisted of pain, pain measurement (NRS, VAS, VRS, and FPS), and assessment/comparison. The inclusion criteria included English language literature with primary/secondary outcome objectives directly comparing ≥2 pain scales in acute pain (age: 13+). Study end points included interscale correlations, patient preferences, provider preferences, study author recommendations, and failure rates. RESULTS: Eight hundred seven studies were retrieved: A total of 42 studies were included. The visual analog scale (n = 42) was most studied, followed by NRS (n = 29), VRS (n = 27), and FPS (n = 11). 93.1% studies showed a high statistical correlation between VAS and NRS. Patients preferred NRS (n = 8/11), followed by FPS (n = 3/11), VRS (n = 2/11), and VAS (n = 1/11). Study authors recommended NRS/VAS (n = 8/19), VRS (n = 6/19), and FPS (n = 1/19). Providers preferred NRS (n = 2/3) and VRS (n = 1/3). The visual analog scale had the highest failure rate (n = 11/12). CONCLUSION: The numeric rating scale is most applicable for dermatologic surgery because of reported patient and provider preferences, lowest failure rates, and most frequent study author recommendations.

BACKGROUND: Nail squamous cell carcinoma (nSCC) is the most common nail unit malignancy. However, no studies to date have evaluated treatment options for nSCC based on recurrence data while controlling for invasion. OBJECTIVE: To identify temporal trends in nSCC treatment modalities and compare treatment outcomes based on invasion. METHODS AND MATERIALS: The authors performed a systematic review of articles published on PubMed, MEDLINE, and Scopus from inception to April 2020 reporting treatment of nSCC. The primary outcome was disease recurrence. RESULTS: Reports of nSCC treatments have increased in the past decade. Mohs micrographic surgery (MMS) is the most common treatment reported overall. The lowest recurrence rates for in situ nSCC were seen with wide surgical excision (WSE) and MMS. For invasive disease, the recurrence rates were lowest with amputation, MMS, and WSE. CONCLUSION: Complete surgical excision of nSCC with either WSE or MMS is associated with lower recurrence rates than limited excision and nonsurgical therapies, regardless of degree of invasion. The prognostic significance of in situ versus invasive disease remains unclear. Confirmation of complete excision may improve outcomes. Digital amputation is indicated for nSCC with bone invasion. Prospective studies and randomized controlled trials are needed to directly compare surgical modalities for nSCC.

BACKGROUND: Determining which postsurgical scar assessment instruments, if any, cover important eyelid outcome measures can either attest to the strength of one or more instruments or reveal the need for a more comprehensive scale. OBJECTIVE: To systematically review validated outcome measures after eyelid surgery and postsurgical scar assessment tools to see whether any individual or combination of 2 assessment tools encompass all relevant, validated eyelid outcome measures. METHODS: Systematic reviews of validated eyelid outcome measures and postsurgical scar assessment tools were conducted using PubMed/MEDLINE and Ovid. Outcome measure papers that met inclusion criteria were sorted into 8 categories: Patient Subjective, Visual Function, Mechanical Function, Daily Activities, Adverse Effects, Aesthetic Quantitative: Clinical Measurements, Aesthetic Qualitative: Global, and Aesthetic Qualitative: Specific. Outcome measure papers were categorized into tiers of evidence support, and assessment tools were evaluated based on which outcome measures each covered. RESULTS: No one or combination of 2 assessment tools covered all selected eyelid outcome measures. Although measures related to the subjective patient experience were included in several of the assessment scales, none covered measures of visual function or eyelid-specific clinical measurements. CONCLUSION: There is currently no existing postsurgical scar assessment instrument that covers all important eyelid-specific outcome measures.

BACKGROUND: The utilization of an assessment instrument that successfully analyzes validated outcome measures for auricular surgery is important for advancing evidence-based medicine. OBJECTIVE: To systematically review postsurgical scar assessment instruments and outcome measures after auricular surgery to assess if any individual or combination of 2 assessment instruments encompass all relevant, validated auricular outcome measures. METHODS: Two systematic reviews were conducted using the PubMed/MEDLINE and Ovid databases: one for postauricular surgical outcome measures and another for postsurgical scar assessment instruments. Auricular outcome measure articles were selected for inclusion if they included at least one auricular-specific validated outcome measure, and assessment tool articles were included if they referenced one or more specific tool(s) specifically designed to assess postsurgical scars. Assessment tools were evaluated based on which outcome measures each covered. RESULTS: There was no single postsurgical scar assessment instrument or combination of 2 instruments that covered all outcome measures within the 5 different categories (psychosocial well-being, functional, objective appearance, subjective appearance, and clinical-related outcomes) after auricular surgery. None of the instruments measured functional outcomes, such as the ability to wear glasses and hearing outcomes. CONCLUSION: There is currently no existing postsurgical scar assessment instrument that covers all outcome measures after auricular surgery.

BACKGROUND: Mohs micrographic surgery (MMS) for cutaneous melanoma is becoming more prevalent, but surgical technique varies. OBJECTIVE: To define variations in published techniques for MMS for melanoma. METHODS AND MATERIALS: A systematic review was performed of PubMed, EMBASE, and Scopus databases to identify all articles describing surgical techniques for MMS for melanoma. Technical details were recorded for the preoperative, intraoperative, and postoperative phases of MMS. RESULTS: Twenty-four articles were included. Mohs surgeons vary in how they assess clinical margins, how wide a margin they excise on the first MMS layer, and how they process tissue to determine tumor stage and margin clearance during MMS for melanoma. CONCLUSION: Mohs micrographic surgery for melanoma is performed with varied surgical techniques. To establish best practices, additional research is necessary to determine how different techniques affect outcomes.

BACKGROUND: Prescription opioids play a large role in the opioid epidemic. Even short-term prescriptions provided postoperatively can lead to dependence. OBJECTIVE: To provide opioid prescription recommendations after Mohs micrographic surgery (MMS) and reconstruction. METHODS: This was a multi-institutional Delphi consensus study consisting of a panel of members of the American College of Mohs Surgery from various practice settings. Participants were first asked to describe scenarios in which they prescribe opioids at various frequencies. These scenarios then underwent 2 Delphi ratings rounds that aimed to identify situations in which opioid prescriptions should, or should not, be routinely prescribed. Consensus was set at ≥80% agreement. Prescription recommendations were then distributed to the panelists for feedback and approval. RESULTS: Twenty-three Mohs surgeons participated in the study. There was no scenario in which consensus was met to routinely provide an opioid prescription. However, there were several scenarios in which consensus were met to not routinely prescribe an opioid. CONCLUSION: Opioids should not be routinely prescribed to every patient undergoing MMS. Prescription recommendations for opioids after MMS and reconstruction may decrease the exposure to these drugs and help combat the opioid epidemic.

BACKGROUND: Despite the large burden of impetigo in childhood and high frequency of pediatric emergency department (ED) visits for skin conditions, limited information exists on the use of EDs for impetigo among US children. OBJECTIVE: Our study aimed to generate national estimates of ED utilization and to identify sociodemographic predictors of impetigo-related ED visits. METHODS: This was a retrospective, cross-sectional study of children ages 1-17 presenting to EDs with a primary diagnosis of impetigo using years 2013-2015 of the Nationwide Emergency Department Sample. RESULTS: Impetigo accounted for 163 909 of the 71 488, 511 pediatric ED visits and was the fourth most common presenting skin diagnosis. Controlling for sociodemographic factors, patients presenting to the ED with impetigo were most likely to be 6-11 years old, male, and from lower-income quartiles. Patients were most likely to be uninsured and most likely to present on weekends in the summer. CONCLUSION: This study provided national-level estimates of ED use for impetigo among US children. Ultimately, the identification of factors associated with increased ED utilization may help in developing targeted interventions to reduce the use of emergency care for impetigo.

BACKGROUND: Inadequate pain reduction during anesthetic injection is a significant medical and surgical problem. Vibratory distraction reduces this pain; however, there are minimal data identifying those who respond best. OBJECTIVE: To quantify analgesia from vibration before anesthetic injection. MATERIALS AND METHODS: In this partially blinded, single-institution trial, adult participants were randomized to intervention (vibratory anesthetic device, VAD ON) or placebo (VAD OFF). Pain was assessed using the 11-point numeric rating scale (NRS). Relative reduction in NRS between VAD OFF and ON was used to identify minimum clinically important and substantially clinically important difference in pain. RESULTS: One hundred one tested sites from 87 subjects were assessed. Sixty-three percent were men with a median age of 66 years. From univariate analysis, males, subjects aged <60, and head and neck (HN) treated subjects had a significant reduction in NRS (p < .05). Multivariate analysis identified NRS reductions in females <60 (p = .012), males ≥70 (p = .002), females and males treated on HN (p = .048 and p = .035, respectively), and males ≥70 treated on HN (p = .012). Substantially clinically important difference (≥57% NRS reduction) included subjects <60, females <70, HN treatment aged 60 to 69, males ≥70, and females treated on HN. CONCLUSION: Vibratory anesthetic device reduces pain during anesthetic injection, primarily for HN treatments and older male subjects.

BACKGROUND: Dermatologic surgery is associated with low postoperative infection rates, averaging from approximately 1% to 4.25%. Often, postoperative infections are treated empirically based on clinical diagnosis of infection, given it can take 48 to 72 hours for a wound culture to identify a pathogen. OBJECTIVE: We aimed to evaluate the efficacy of empiric antibiotics in dermatologic surgery postoperative infections and if wound cultures change postoperative antibiotic therapy. METHODS: A 7-center, retrospective analysis of postoperative infections, with culture data, in dermatologic surgery patients was performed. RESULTS: Of 91 cases of clinically diagnosed postoperative infection, 82.4% (n = 75) were successfully treated with empiric oral antibiotics (95% confidence interval [0.73-0.89], p < .0001). In 16 (17.6%) cases, initial empiric antibiotics were unsuccessful, and wound culture results altered antibiotic therapy in 9 cases (9.9%) with 6 (6.6%) of these cases requiring additional coverage for methicillin-resistant Staphylococcus aureus (MRSA). CONCLUSION: Empiric antibiotic treatment is usually appropriate for patients with postoperative surgical-site infections with wound cultures altering antibiotic management in a minority of cases. When empiric antibiotics fail, lack of MRSA coverage is usually the cause; therefore, providers should be aware of local MRSA prevalence and susceptibilities.

Skin cancer is the most common malignancy affecting solid organ transplant recipients (SOTR), and SOTR experience increased skin cancer-associated morbidity and mortality. There are no formal multidisciplinary guidelines for skin cancer screening after transplant, and current practices are widely variable. We conducted three rounds of Delphi method surveys with a panel of 84 U.S. dermatologists and transplant physicians to establish skin cancer screening recommendations for SOTR. The transplant team should risk stratify SOTR for screening, and dermatologists should perform skin cancer screening by full-body skin examination. SOTR with a history of skin cancer should continue regular follow-up with dermatology for skin cancer surveillance. High-risk transplant patients include thoracic organ recipients, SOTR age 50 and above, and male SOTR. High-risk Caucasian patients should be screened within 2 years after transplant, all Caucasian, Asian, Hispanic, and high-risk African American patients should be screened within 5 years after transplant. No consensus was reached regarding screening for low-risk African American SOTR. We propose a standardized approach to skin cancer screening in SOTR based on multidisciplinary expert consensus. These guidelines prioritize and emphasize the need for screening for SOTR at greatest risk for skin cancer.
