Cost-Effectiveness Analysis of Operating Room and In-Office Reconstruction of Skin Cancer Defects.

OBJECTIVE: Reconstruction of skin cancer and Mohs micrographic surgery (MMS) defects of the head and neck is performed in both in-office and operating room (OR). This study intends to understand cost differences between reconstructive surgery for skin cancer defects in the OR and clinic to perform a cost-effectiveness analysis with single-institution patient satisfaction data. STUDY DESIGN: Population-based retrospective analysis of cost data and an institutional, prospective survey of patient satisfaction. SETTING: National insurance database and institutional survey. METHODS: The Merative® MarketScan database was queried to identify claims involving the reconstruction of skin cancer defects of the head/neck between 2013 and 2020 for cost-analysis by setting (OR vs clinic). Patients undergoing operative and clinic-based reconstruction of MMS defects by 3 different surgeons at a single institution in 2023 were surveyed for satisfaction using a 5-point Likert scale. Data was coupled for cost-benefit analysis. Analysis was performed using propensity-matched samples. RESULTS: Using Marketscan, 1206 patients were analyzed for cost data. OR cases had a higher median baseline cost of $2308 (interquartile range [IQR]: 1484-3889) compared to procedures in the office (median $987, IQR: 784-1454, P < .001). Survey data from 116 patients revealed no significant difference in scores between OR and clinic cases (clinic: 4.57 vs OR: 4.60, P = .8752). Using propensity-matched subsets, providers incur an additional $4744 for a reduction in satisfaction of 0.083 when performing cases in the OR. CONCLUSION: Lower cost is associated with reconstructive procedures performed in the office. This study is the first cost analysis of head and neck skin cancer reconstruction based on procedural settings and will be valuable to surgeons in considering practice patterns and resource utilization.

Challenges and opportunities for Mohs surgery implementation in African healthcare systems.

BACKGROUND: Skin cancer in African countries results primarily from exposure to high ambient ultraviolet radiation. It is an emerging public health issue with limited improvement in management services. Mohs surgery, a renowned surgical procedure in the treatment of skin cancer, involves exact tumor excision along with horizontal frozen tissue examination. It is known to minimize the defect size and improve patient outcomes. Therefore, Mohs surgery is highly effective for almost all nonmelanoma skin cancers. Despite its proven potential, the implementation of Mohs surgery in Africa faces various limitations. This commentary seeks to provide insights into the current threats and opportunities surrounding the execution of Mohs surgery in African healthcare systems. The role of governments, healthcare professionals, and international organizations is also highlighted in this paper. METHODS: A literature search was conducted by retrieving articles from PubMed and Google Scholar. Previous articles that discuss skin cancer, Mohs surgery, and cancer in Africa were analysed to understand the implementation aspects of Mohs surgery in Africa. RESULTS: The implementation of Mohs surgery in Africa is very limited due to challenges such as inadequately trained healthcare professionals, costs associated with the surgery, and cultural beliefs and misconceptions. Nevertheless, telemedicine has been used in surgical consultations regarding the postoperative management of patients who undergo Mohs surgery. CONCLUSION: Despite advances in medicine, African dermatological health care remains underdeveloped. Therefore, increased investment in healthcare training, infrastructure development, and more African-based skin cancer studies are necessary and paramount factors for the expansion and accessibility of Mohs surgery in Africa.

Novel imaging techniques for tumor margin detection in basal cell carcinoma: a systematic scoping review of FDA and EMA-approved imaging modalities.

Mohs micrographic surgery (MMS) is the gold standard for removing basal cell carcinomas (BCCs) due to its ability to guarantee 100% margin evaluation through frozen section histopathology, offering the highest cure rate among current treatments. However, noninvasive imaging technologies have emerged as promising alternatives to clinical assessment for defining presurgical margins. This systematic scoping review examines the efficacy of these imaging modalities, focusing on those approved for clinical use by the United States Food and Drug Administration (FDA) or the European Medicines Agency (EMA). A systematic search of EMBASE, Scopus, PubMed, and the Cochrane Public Library databases identified 11 relevant studies out of 2123 records, encompassing 644 lesions across five imaging techniques. The findings suggest that dermoscopy, high-frequency ultrasound (HFUS), optical coherence tomography (OCT), line-field optical coherence tomography (LC-OCT), and reflectance confocal microscopy (RCM) show potential in detecting BCC margins, which could enhance MMS by providing better preoperative planning, informing patients of expected defect size, aiding in reconstruction decisions, and reducing overall procedure costs. This review discusses the benefits and limitations of each technique, offering insights into how these innovations could influence the future of BCC management. Emerging imaging techniques could enhance MMS by improving BCC margin assessment and reducing costs. Their adoption will depend on price and ease of use.

[Translated article] Postoperative Wound Care in Dermatologic Surgery: Update And Narrative Review.

Dermatologic surgery is associated with a very low risk of complications. There is no widely accepted, evidence-based protocol with recommendations for postoperative wound care after dermatologic surgery. In this narrative review, we will be discussing the evidence on surgical wound care products and procedures. Overall, we found relatively few studies and, in many cases, a lack of statistically significant differences, possibly because of the low rate of complications. We'll be discussing the evidence on when we should initiate wound care procedures and their frequency, the type of ointment and antiseptics that should be applied, and the type of dressings that should be used. Despite the very few studies available on postoperative wound care following dermatologic surgery, there is sufficient evidence as to not recommend the use of prophylactic topical antibiotics. We also analyze the currently available evidence on surgical wound care in special situations, such as management of skin grafts, partial skin graft donor sites, xenografts/biomembranes, and surgical wounds to the legs.

40-Gene expression profile test predicting metastatic risk in localized, high-risk cutaneous squamous cell carcinoma for peer review.

This case study investigates the use of a 40-gene expression profile to independently predict the risk of metastasis in an immunocompromised 75-year-old male patient with cutaneous squamous cell carcinoma of his left cheek. The patient's previous medical history included non-melanoma skin cancer. Traditional staging methods, such as those from the American Joint Committee on Cancer 8th edition and Brigham and Women's Hospital, suggested a high risk of metastasis for this patient. However, the 40-gene expression profile test identified the patient as having a low risk (Class 1 result) of metastasis within 3 years. The patient successfully underwent Mohs surgery, and pathology was notable for positive perineural invasion of large caliber nerves. This case highlights the potential of the 40-gene expression profile as an independent predictor in assessing metastatic risk compared to traditional staging methods.

Current Advances and Challenges in the Management of Cutaneous Squamous Cell Carcinoma in Immunosuppressed Patients.

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin malignancy and poses a significant risk to immunosuppressed patients, such as solid organ transplant recipients and those with hematopoietic malignancies, who are up to 100 times more likely to develop cSCC compared with the general population. This review summarizes the current state of treatment for cSCC in immunosuppressed patients, focusing on prevention, prophylaxis, surgical and non-surgical treatments, and emerging therapies. Preventative measures, including high-SPF sunscreen and prophylactic retinoids, are crucial for reducing cSCC incidence in these patients. Adjusting immunosuppressive regimens, particularly favoring mTOR inhibitors over calcineurin inhibitors, has been shown to lower cSCC risk. Surgical excision and Mohs micrographic surgery remain the primary treatments, with adjuvant radiation therapy recommended for high-risk cases. Traditional chemotherapy and targeted therapies like EGFR inhibitors have been utilized, though their efficacy varies. Immunotherapy, particularly with agents like cemiplimab and pembrolizumab, has shown promise, but its use in immunosuppressed patients requires further investigation due to potential risks of organ rejection and exacerbation of underlying conditions. Treatment of cSCC in immunosuppressed patients is multifaceted, involving preventive strategies, tailored surgical approaches, and cautious use of systemic therapies. While immunotherapy has emerged as a promising option, its application in immunosuppressed populations necessitates further research to optimize safety and efficacy. Future studies should focus on the integration of personalized medicine and combination therapies to improve outcomes for this vulnerable patient group.

How Dermatologic Surgeons Decide to Proceed with Surgery for Nonmelanoma Skin Cancer When Site Identification is Initially Uncertain: A Nationwide, Multicenter, Prospective Study.

BACKGROUND: Few studies show how dermatologic surgeons manage problems with site identification. OBJECTIVE: To estimate frequency and characterize management of skin cancer treated by surgery when the anatomic location of the tumor is in question. METHODS: Nationwide, prospective, multi-site cohort study. RESULTS: Among 17,076 cases at 22 centers, 98 (0.60%) were lesions in question (LIQ) for which site identification was initially uncertain, with these more often in patients who were male, older, and biopsied more than 30 days ago. Surgeons employed on average 5.0 (95% CI: 4.61-5.39) additional techniques to confirm the site location, with common approaches including: re-checking available documentation (90 lesions, 92%); performing an expanded physical examination (89 lesions, 91%); and asking the patient to point using a mirror (61 lesions, 62%). In 15%, photographs were requested from the biopsying provider, and also in 15%, frozen section biopsies were obtained. In 10%, the referring physician was contacted. Eventually, surgeons succeeded in definitively identifying 82% (80/98) of initially uncertain sites, with the remaining 18% (18/98) postponed. Most postponed surgeries were at non-facial sites. LIMITATIONS: Sites were academic centers. CONCLUSIONS: When the anatomic location of the tumor is uncertain, dermatologic surgeons use multiple methods to identify the site, and sometimes cases are postponed.

Solitary Superficial Angiomyxoma in an Uncommon Location: A Case Report and Literature Review.

Superficial angiomyxoma (SAM) is a rare, benign, and slow-growing soft tissue tumor with a tendency for frequent local recurrence. Most SAMs are solitary and sporadic. However, multiple SAMs, particularly on the external ear or eyelids, may be the initial or only sign of the Carney complex, an autosomal dominant syndrome that impacts various organs, including the heart, breasts, and skin, and is linked to endocrine hyperactivity. To ensure an accurate diagnosis, a comprehensive patient interview, physical examination, and laboratory tests, including endocrine-specific markers and imaging studies, are essential. Due to the high risk of recurrence, especially in large, encapsulated lesions, complete surgical excision is the preferred treatment approach. We present a case of a 24-year-old female with SAM on the shoulder, review the relevant literature, and discuss the pathogenesis and appropriate management of such cases.

Rare Intravascular Involvement of Pleomorphic Dermal Sarcoma Seen During Mohs Micrographic Surgery.

Pleomorphic dermal sarcoma (PDS) and atypical fibroxanthoma (AFX) are rare mesenchymal tumors that share similar clinical, histological, and immunohistochemical characteristics. Careful histopathological examination of a biopsy specimen that includes subcutaneous fat remains the preferred way to differentiate between these tumors. AFX is limited to dermal invasion, whereas PDS demonstrates deeper invasion. Moreover, PDS may present with tumor necrosis and high-grade histological findings, such as lymphovascular and perineural invasion, features absent in AFX. However, like PDS, AFX is a diagnosis of exclusion, and an exhaustive immunohistochemistry panel is recommended to distinguish these tumors from other spindled cell tumors in the differential diagnosis. The authors present the case of an 86-year-old man with biopsy-suspected AFX who was referred for Mohs micrographic surgery for tumor excision. During Mohs, the tumor was observed to have invaded deeply into the subcutaneous tissue and galeal aponeurosis, aligning more closely with a PDS. The diagnosis of PDS was confirmed using en face processing during Mohs surgery, which captured the intravascular involvement of a solitary vessel. Differentiating between PDS and AFX is important because PDS is a more aggressive tumor, with a higher rate of local recurrence and metastasis, and requires closer monitoring.

Comparison of Infection Rate Between Sterile and Nonsterile Gloves During Mohs Micrographic Surgery: An Updated Systematic Review and Meta-Analysis.

BACKGROUND: Mohs micrographic surgery (MMS) is a well-established technique for the removal of various types of skin cancers. While sterile gloves (SG) are commonly used in skin surgeries such as MMS, additional understanding of their effectiveness compared to nonsterile gloves (NSG) in preventing local infection is required. OBJECTIVE: We aimed to perform an updated systematic review and meta-analysis comparing the use of SG with NSG for local infection rate post-MMS and point out cost discrepancies between these 2 scenarios. METHODS: We searched MEDLINE, Embase, and Cochrane for studies published up to August 2023 comparing the use of SG with NSG during MMS that reported the outcome of wound infection. RESULTS: A total of 4 studies with 10,644 MMS were included, of which 7512 (70.6%) were performed with SG and 3132 (29.4%) were done with NSG. In the SG group, 232 out of 7512 cases (3.1%) developed infection compared to 64 out of 3132 (2.0%) in the NSG group [odds ratio (OR) 1.14; 95% confidence interval (CI) 0.85-1.52; P = .39; I2 = 0%]. Therefore, the post-MMS infection rates were not significantly different between SG and NSG groups, including in the excision (OR 0.92; 95% CI 0.48-1.79; P = .81; I2 = 0%) and reconstruction (OR 1.17; 95% CI 0.85-1.60; P = .34; I2 = 0%) subanalysis. Regarding the mean cost of the gloves, the NSG pair was $0.24, approximately 10% of the price of the SG pair ($2.27). CONCLUSION: The results support that, compared to SG, NSG are equally effective in preventing infections during MMS while offering significant cost savings without compromising patient outcomes.Protocol registration: PROSPERO, CRD42023458525.

A Surgical Conundrum: Addressing a Large Nasal Defect Following Mohs Micrographic Surgery.

Managing large nasal defects following Mohs surgery presents complex reconstructive challenges due to the nose's prominent and visible nature. These cases require a careful balance of preserving structural integrity, optimizing cosmetic outcomes, and maintaining vascular health. In situations where primary closure is impractical due to defect size and location, innovative techniques like the double rhomboid transposition flap offer versatile solutions, addressing both aesthetic concerns and functional requirements. The double rhomboid flap allows surgeons to achieve continuity of surrounding tissue, ensuring aesthetically pleasing texture, color, and thickness while minimizing complications like skin tension and potential airway issues. This case highlights the reconstructive challenges faced in managing large nasal defects following Mohs micrographic surgery for basal cell carcinoma. An 84-year-old male presented with a significant nasal defect following Mohs surgery that involved the dorsum, sidewall, tip, and ala, complicating primary closure due to skin tension and cosmetic concerns. Utilizing a double rhomboid transposition flap technique allowed for effective aesthetic and structural reconstruction, addressing skin tension and preserving nasal symmetry. This case emphasizes the importance of tailored reconstructive strategies to achieve optimal cosmetic and functional outcomes in complex nasal Mohs defects.

Wood's light in inflammatory and autoimmune dermatoses, infections and skin cancer. / Luz de Wood en dermatosis inflamatorias, autoinmunes, infecciones y cáncer cutáneo.

Wood's lamp (WL) is a useful, cost-effective, and easy-to-learn diagnostic tool. Despite its advantages, the use of WL among dermatologists is limited. In porokeratosis, the "diamond necklace" sign often reported is consistent with the white fluorescence of the hyperkeratotic scale. Subclinical morphea lesions are seen as well-defined dark macules. Among pigmentary disorders, the bluish fluorescence of vitiligo, increased contrast of epidermal melasma, and follicular-centered red fluorescence of progressive macular hypomelanosis stand out. Regarding skin infections, erythrasma is associated with a coral red fluorescence; tinea versicolor, with a yellow-green fluorescence; Pseudomonas aeuriginosa, with a green fluorescence; and scabies with a blue-white fluorescence in the acarine grooves. In skin cancer, WL has been used to outline the surgical margins of lentigo maligna and non-melanoma skin cancer, with variable results.
