RESUMEN
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.
RESUMEN
BACKGROUND: As internet access continues to expand, online health care information is increasingly influencing patient decisions. Mohs micrographic surgery (MMS) is commonly used in the field of dermatology but may be unfamiliar to many patients. OBJECTIVE: The purpose of this study was to identify and analyze online educational resources regarding MMS and learn how to optimize the understanding and informational content of MMS for patients and their families. MATERIALS AND METHODS: Thirty-two websites were evaluated for authorship, quality, and readability using DISCERN, JAMA Benchmark Criteria, and Flesch-Kincaid tests. RESULTS: Physician-authored content showed a trend toward higher quality (p = .058). Google scored higher in specific DISCERN questions when overlapping websites were excluded. Bing scored higher in JAMA criteria (p = .03) in criteria such as authorship and currency. Higher DISCERN scores correlated with lower readability. CONCLUSION: Physician involvement improves content quality, raising questions about physicians' responsibility in online resource creation. Correlations between content quality and readability highlight potential challenges for certain demographics. Balancing medical accuracy with comprehensibility is crucial for equitable patient education. This study underscores the need to refine online resources, ensuring accurate, transparent, and accessible health care information.
RESUMEN
Previous scar scales have focused on verbal descriptions. A nonverbal visual assessment tool would provide a simple way for patients and physicians to quantify scar appearance. The authors sought to use a validated visual assessment tool for linear surgical scars to assess linear scars on the face and to determine whether patients and surgeons rate scars similarly. A total of 143 patients with linear facial scars resulting from repair of Mohs micrographic surgery defects used the visual assessment tool to rate their surgical scar. Six physicians used the tool to rate a subset of the patients' scar photographs. The scar ratings for patients and physicians were compared. Among the scars rated by both the patients and physicians (n = 79), patients had a significantly lower mean (i.e., more favorable) rating compared with the physicians. This was a single-center study including only Caucasian patients. The visual assessment tool to rate linear surgical scars provided a simple method for both patients and physicians to assess the overall appearance of postsurgical scars. Difference in the scar ranking between patients and physicians indicate the importance of incorporating both patient and physician point of view when assessing scars.

BACKGROUND: Hypertrophic lichen planus is a chronic variant of lichen planus with controversial malignant association. OBJECTIVE: To describe and analyze the relationship of squamous cell carcinoma (SCC) and hypertrophic lichen planus. MATERIALS AND METHODS: A retrospective chart review of patients with hypertrophic lichen planus and SCC was performed at the authors' institution. Thereafter, scientific databases were searched for articles reporting cases of SCC arising in hypertrophic lichen planus. Patient demographics, immune status, lichen planus features, and SCC data points were extracted for each patient and evaluated. RESULTS: Thirty-eight cases of SCC in hypertrophic lichen planus occurred in 16 women, average age: 61.4, and 22 men, average age: 51.3, after a lag time of 88 days to 40 years. Squamous cell carcinoma was uniformly located on the lower extremity. Men had larger SCC than women (p = .027) and a significantly longer lag time to SCC development (p = .002). Long lag time was associated with a smaller SCC size (p = .032). CONCLUSION: In the past, hypertrophic lichen planus and SCC have been considered isolated diseases. Based on an increasing number of cases, the association between hypertrophic lichen planus and keratinocyte malignancies warrants surveillance.

BACKGROUND: The purpose of this study was to determine the patient reasoning behind treatment choice after palliative surgical consultation. METHODS: Patients undergoing palliative surgical consultation were prospectively enrolled in this observational cohort study (11/2009-5/2011) and administered an open-ended questionnaire asking for their reasoning in choosing their treatment strategy. RESULTS: Of 98 patients enrolled, 54 were treated non-operatively and 44 with surgery. Patient responses indicating their reason for treatment selection were categorized into (1) quality of life or symptom relief, (2) unclear or response not related to treatment strategy, (3) increase length of life, (4) treat the cancer, (5) concerns over surgical complications, (6) doctor's recommendation, (7) religious reasons for treatment choice, and (8) for family. The most frequently cited reason for treatment selection was symptom relief or quality of life improvement in 46 patients. Thirty-eight patients cited their doctor's recommendation while 20 patients selected their treatment to increase length of life or treat their cancer. Only 2 patients cited concerns over surgical complications as their reason for choosing their treatment strategy. CONCLUSIONS: The most common reasons for treatment selection in palliative surgical consultation include symptom relief or improvement in quality of life and the doctor's recommendation with few patients listing concerns over surgical morbidity.

BACKGROUND: While bilobed and trilobed transposition flaps are established workhorses for nasal reconstruction, their utility is often limited to defects less than 1.5 cm, subjecting patients to more involved multistage or cosmetically less favorable repairs. We highlight the use of bilobed and trilobed transposition flaps for intermediate (≥ 1.5 cm) and large (≥ 2.0 cm) nasal defects. METHODS: Patients reconstructed with multilobed transposition flaps 2017-2020 were identified at two institutions. Validated scar scale (SCAR) and patient component of the patient and observer scar assessment survey (POSAS) were used to assess patient outcomes at a minimum 5-week follow-up. Statistical analyses were performed. RESULTS: Thirty-four patients were identified with mean defect size 1.8 cm diameter. There were no major postoperative events. Scar revision was performed in 9 patients. The mean provider SCAR score was 3.06 (best possible 0, worst possible 13). The mean patient arm of the SCAR scale and POSAS were 0.07 (best possible 0, worst possible 2) and 10.93 (best possible 6, worst possible 60), respectively. CONCLUSION: Bilobed and trilobed flaps have excellent outcomes for intermediate and large nasal defects.

We report the case of a 6-year-old girl with no notable medical history who presented to the dermatology clinic for evaluation of left leg pain with an overlying erythematous rash of 4 days' duration. Clinical examination revealed pink patches and plaques in a unilateral L5 distribution with an isolated pinpoint vesicle. Direct fluorescent antibody testing confirmed varicella-zoster virus (VZV) infection, establishing a diagnosis of herpes zoster (HZ). The patient previously had received the VZV vaccine in the left leg and arm and had no history of primary VZV infection. We summarize this case and discuss the epidemiology and clinical characteristics of HZ in vaccinated children.

The immune checkpoint targeted agents, anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and anti-programed cell death 1 (PD-1) or anti-programmed death ligand 1 (PD-L1) inhibitors are frequently associated with cutaneous side effects that are often dose limiting and can lead to discontinuation of therapy. Ipilimumab, a CTLA-4 inhibitor, is most commonly associated with a morbilliform eruption on the trunk and extremities and pruritus. More severe cutaneous toxicities reported include toxic epidermal necrolysis and severe drug rash with eosinophila and systemic symptoms. Recent case reports of Sweet syndrome and cutaneous sarcoidosis have also recently been described after treatment with ipilimumab. The cutaneous events usually occur early in the course of treatment and are dose dependent. PD-1 inhibitors, nivolumab and pembrolizumab, induce similar but less severe toxicities compared with the CTLA-4 inhibitors. The most common cutaneous adverse events include lichenoid reactions, eczema, vitiligo, and pruritus. Lichenoid oral mucosal lesions located on the tongue, buccal mucosa, lips, or gingivae or located on all of these have also recently been described. The time of onset of the cutaneous events with the PD-1 inhibitors occurs later than that seen with the CTLA-4 inhibitors. Anti-PD-L1 antibodies, such as atezolizumab, have a similar side effect profile compared with the PD-1 inhibitors. Combination of immune checkpoint inhibitors, ipilimumab and nivolumab, has recently been approved for the treatment of advanced melanoma. The combination therapy is associated with a more severe side effect profile compared with the agents used as monotherapy. We discuss the most frequently encountered cutaneous side effects of the immune checkpoint inhibitors and review the recommended management strategies.
