Review
Cutaneous malignancies affecting the ear, exacerbated by extensive ultraviolet (UV) exposure, pose intricate challenges owing to the organ's complex anatomy. This article investigates how the anatomy contributes to late-stage diagnoses and ensuing complexities in surgical interventions. Mohs Micrographic Surgery (MMS), acknowledged as the gold standard for treating most cutaneous malignancies of the ear, ensures superior margin control and cure rates. However, the ear's intricacy necessitates careful consideration of tissue availability and aesthetic outcomes. The manuscript explores new technologies like Reflectance Confocal Microscopy (RCM), Optical Coherence Tomography (OCT), High-Frequency, High-Resolution Ultrasound (HFHRUS), and Raman spectroscopy (RS). These technologies hold the promise of enhancing diagnostic accuracy and providing real-time visualization of excised tissue, thereby improving tumor margin assessments. Dermoscopy continues to be a valuable non-invasive tool for identifying malignant lesions. Staining methods in Mohs surgery are discussed, emphasizing hematoxylin and eosin (H&E) as the gold standard for evaluating tumor margins. Toluidine blue is explored for potential applications in assessing basal cell carcinomas (BCC), and immunohistochemical staining is considered for detecting proteins associated with specific malignancies. As MMS and imaging technologies advance, a thorough evaluation of their practicality, cost-effectiveness, and benefits becomes essential for enhancing surgical outcomes and patient care. The potential synergy of artificial intelligence with these innovations holds promise in revolutionizing tumor detection and improving the efficacy of cutaneous malignancy treatments.

Review
Music interventions in medicine have been shown to reduce anxiety and depression, decrease pain, and improve quality of life; however, a review of clinical music interventions in dermatology is lacking. Studies have shown that playing music for patients undergoing dermatologic procedures (Mohs surgery and anesthetic injections) can decrease pain and anxiety. Patients with pruritic conditions-such as psoriasis, neurodermatitis, atopic dermatitis, contact eczema, and situations requiring hemodialysis-have exhibited decreased levels of disease burden and pain when listening to preferred music, pre-chosen music, and live music. Studies suggest that listening to certain types of music may also alter serum cytokines, affecting the allergic wheal response. Additional research is necessary to determine the full potential and practical applications for clinical music interventions in dermatology. Future research should focus on targeting skin conditions that may benefit from the psychological, inflammatory, and immune effects of music.

Review
Lentigo maligna (LM) is a melanoma in situ that is prevalent in chronically sun-damaged skin. Characterized by a slow growth pattern and high mutation rates due to chronic UV exposure, LM poses diagnostic and therapeutic challenges, particularly given its tendency to mimic other skin lesions and its occurrence in cosmetically sensitive areas. Its diagnosis is based on an integrated approach using dermoscopy and reflectance confocal microscopy (RCM). Despite its slow progression, LM can evolve into lentigo maligna melanoma (LMM), making its treatment necessary. Treatment modalities encompass both surgical and non-surgical methods. Surgical treatments like Wide Local Excision (WLE) and Mohs Micrographic Surgery (MMS) aim for clear histological margins. WLE, a standard melanoma surgery, faces challenges from LM's subclinical extensions, which increase the recurrence risk. MMS, effective for large or poorly defined lesions, is defined by precise margin control while considering cosmetic outcomes. Non-surgical options, including radiotherapy and imiquimod, are alternatives for non-surgical candidates. Radiotherapy has been effective since the 1950s, offering good control and cosmetic results, especially for older patients. Imiquimod, an immunomodulator, shows promise in treating LM, though its application remains off-label. The increasing incidence of LM/LMM necessitates a balance in treatment choices to minimize recurrence and maintain cosmetic integrity. A multidisciplinary approach, integrating clinical examination with dermoscopy and RCM and histological assessment, is essential for accurate diagnosis and effective LM management.

The purpose of this study is to illustrate demographic trends among Mohs Micrographic Surgery (MMS) Fellowship Directors. Our search was constructed from the 2022 to 2023 Mohs Micrographic Surgery Fellowship Directory on the Accreditation Council for Graduate Medical Education (ACGME) website. Datapoints gathered included: age, sex, residency/fellowship training location, time since training completion until FD appointment, length in FD role, and personal research H-index. We identified 77 FDs, of which all 77 were included in this study. The mean age was 55.5 years; 55 (71.4%) were men and 20 (26.0%) were women. Most of the FDs who completed the survey did not self-report ethnicity or race, so these measures were not included. The top residency institutions that produced the most FDs were Cleveland Clinic (n = 4), Mayo Clinic (n = 4), New York University Medical Center (NYU, n = 4), and University of California-Los Angeles (UCLA, n = 4); the top fellowship institutions were NYU (n = 7), UCLA (n = 5), Cleveland Clinic (n = 4), and Geisinger Medical Center (n = 4). The mean H-index was 15.9, the mean number of peer-reviewed publications was 71, and the mean time from training completion until FD appointment was 10 years. Our results indicate that a majority of FDs are men (71.4%) and that FDs are more likely to have graduated from certain residency and fellowship programs.

Review
BACKGROUND
The use of Mohs micrographic surgery (MMS) in melanoma treatment has divided opinion and evidence-based guidelines are lacking.
OBJECTIVES
This systematic review aimed to analyse clinical outcomes for patients with invasive melanomas treated with Mohs rather than wide local excision (WLE).
METHODS
Embase, MEDLINE and Cochrane databases (to 30 August 2023) were searched for studies using Mohs to treat invasive melanoma. Outcomes of interest were local recurrence and death from melanoma.
RESULTS
Thirty-five articles involving 41,499 patients with invasive melanoma treated with Mohs were identified. Sixteen studies compared Mohs with WLE and 19 were Mohs-only, non-comparative studies. Patients treated with Mohs differed significantly from those undergoing WLE, in particular Mohs patients were older and had thinner melanomas. Two comparative studies using the same data source reported adjusted hazard ratios for melanoma-specific death and both showed no significant difference between Mohs and WLE-treated patients; 0.87 (95% CI 0.55-1.35) and 1.20 (95% CI 0.71-20.36). There was also no statistically significant difference in local recurrence risk; the unadjusted risk ratio for patients treated with Mohs was 0.46 (95% CI 0.14-1.51 p = 0.20) with moderate heterogeneity (I = 62%). No studies reported multivariable analyses for risk of local recurrence. Many studies generated from relatively few and often overlapping data sets have reported the use of Mohs to treat patients with invasive melanoma. Fewer studies were comparative between Mohs and WLE and these reported substantially different baseline risks of recurrence and death from melanoma between the groups. Mohs has generally been used for thinner melanomas in older patients; therefore, comparisons based on univariable analyses are likely to have been misleading.
CONCLUSIONS
On the basis of currently available data, it is not possible to reliably assess whether outcomes differ if invasive melanomas with comparable features are treated with Mohs or WLE, and randomized trial evidence will be required for reliable conclusions to be reached.

The risk of skin cancer in persons living with HIV (PLWH) is an evolving subject area shaped by the use of antiretroviral therapy. Keratinocyte carcinomas, including basal cell carcinoma and squamous cell carcinoma, have a high incidence in the general population as well as in PLWH. PLWH may have a higher risk of squamous cell carcinoma when compared to the general population. In addition, Merkel cell carcinoma and sebaceous carcinoma exhibit higher incidence rates in PLWH. Data on melanoma risk are varied. Risks of skin cancer may be influenced by vigilant surveillance, photosensitivity, and immune status. Screening for skin cancer is generally recommended, although national guidelines vary in specific recommendations. Treatments range from topical therapies to surgeries to immune checkpoint inhibitors, with Mohs micrographic surgery playing an important role. Data on immune checkpoint inhibitors suggest safe and efficacious use in PLWH, although larger trials are warranted. The dynamic interplay among HIV, antiretroviral use and immunosuppression, and the risk and treatment of skin cancer underscores the importance of rigorous research studies and screening and treatment guidelines specific to this population.

Review
Skin cancer is one of the most common types of cancer worldwide, and it can affect people of all ages, races, and genders. Mohs micrographic surgery (MMS), a specialized type of skin cancer surgery, boasts the highest cure rates for various types of skin malignancies. Slow Mohs surgery (SMS) is a methodical and meticulous approach to MMS that involves careful and deliberate examination of tissue samples to ensure the complete removal of skin cancer while preserving as much healthy tissue as possible. Both SMS and MMS have been indicated to be effective treatment options for skin cancer, depending on the type and stage of cancer. This case-control study analysis compares the efficacy of SMS for melanoma with that of MMS for squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). We analyzed data from the past two decades to assess recurrence rates and treatment-related complications. Our findings suggest that SMS for melanoma achieves comparable outcomes to MMS in SCC and BCC. Both approaches demonstrated similar cure rates and complication profiles. However, further prospective studies are necessary to solidify these findings and refine the specific role of SMS in melanoma therapy.

Review
Mohs Micrographic Surgery (MMS) for treatment of melanoma offers several advantages over wide local excision (WLE), including complete histologic margin evaluation, same-day resection and closure, and sparing of healthy tissue in critical anatomic sites. Recently, a large volume of clinical data demonstrating efficacy in MMS treatment of melanoma was published, leading to emerging patient safety considerations of incurred treatment costs, risk of tumor upstaging, and failure of care coordination for sentinel lymph node biopsy (SLNB). MMS offers a safe, effective, and value-based treatment for both melanoma in situ (MIS) and invasive melanoma (IM), particularly with immunohistochemistry use on frozen sections. Compared to wide local excision, MMS treatment demonstrates similar or improved outcomes for local tumor recurrence, melanoma-specific survival, and overall survival at long-term follow-up. Tumor upstaging risk is low, and if present, alteration to clinical management is minimal. Discussion of SLNB for eligible head and neck IM cases should be done prior to MMS. Though challenging, successful multidisciplinary coordination of SLNB with MMS has been demonstrated. Herein, we provide a detailed clinical review of evidence for MMS treatment of cutaneous melanoma and offer recommendations to address current controversies surrounding the evolving paradigm of surgical management for both MIS and invasive melanoma (IM).
