Reconstruction of Perioral Defects After Mohs Micrographic Surgery or Excision: A Systematic Review of the Literature.

BACKGROUND: Although many repair methods for postsurgical lip defects have been described, the literature lacks a comprehensive review of these methods. OBJECTIVE: To perform a systematic review of lip defect repair methods after Mohs surgery or excisions. MATERIALS AND METHODS: Terms related to perioral anatomy, Mohs surgery and excision, and reconstruction were used to search 8 databases. Articles were included if they reported postsurgical lip repair data for 4 or more patients, were in English, and were published from 2004 onward. Two reviewers screened all titles and abstracts, followed by the full texts of the remaining articles. Data were then extracted including author specialties, study design, demographic, tumor, and defect information, surgical procedures, outcomes, and complications. RESULTS: Forty-two studies were eligible, including a randomized trial, 25 case series, and 16 cohort studies. Most were written by dermatologic or plastic surgeons, and most studies were small, with an average subject number of 61. Very few studies used structured outcome measures. Many repair methods were described, the most common of which were linear closures and various flaps. CONCLUSION: Many repair methods for lip defects have been published, but overall, the quality of the available evidence is low.

Periocular Mohs Reconstruction by Lateral Canthotomy With Inferior Cantholysis: A Retrospective Study.

BACKGROUND: Most eyelid defects after Mohs micrographic surgery are referred to oculoplastic surgery or plastic surgery for reconstruction, but growing evidence suggests the safety of such repairs performed by dermatologic surgeons is equivalent if not better. Lateral canthotomy with inferior cantholysis may be used by the dermatologic surgeon to reconstruct larger lower eyelid defects. OBJECTIVE: To demonstrate lateral canthotomy with inferior cantholysis performed by the dermatologic surgeon can result in safe, functionally and cosmetically acceptable surgical outcomes. MATERIALS AND METHODS: An institutional review board-approved retrospective study of repairs performed by a single dermatologic surgeon between January 2013 and August 2019. Patient demographics, operative and follow-up notes were reviewed. Two cosmetic dermatologists assessed aesthetic results based on final follow-up photographs using a visual analogue scale. RESULTS: Eight cases were included in the analysis. Seventy-five percent of patients were men, with a mean age of 74.1 years old. All tumors were basal cell carcinoma; the mean defect size was 2.4 cm2. No serious complications or postoperative interventions occurred. The median cosmetic score was 85.6 ± 11.5. CONCLUSION: Dermatologic surgeons can safely perform repairs of lower eyelid defects with lateral canthotomy with inferior cantholysis, achieving satisfactory functional and cosmetic outcomes.

Multifocal infantile hemangiomas associated with concomitant giant hepatic rapidly involuting congenital hemangioma.

We present a 9-day-old girl with multifocal cutaneous and hepatic infantile hemangiomas as well as a hepatic rapidly involuting congenital hemangioma. These two distinct vascular tumors have rarely been reported to co-occur. We additionally review the sonographic features that distinguish a hepatic congenital hemangioma from the hepatic infantile hemangioma.

Mohs Micrographic Surgery at Challenging Anatomical Sites.

BACKGROUND: Mohs micrographic surgery (MMS) is often the treatment of choice for skin cancer removal as it maximizes normal tissue sparing and can be paired with a reconstructive approach that optimizes function and cosmesis. Many tumors on the eyelid, nose, ear, and genitals are particularly well suited for MMS but can be challenging for the dermatologic surgeon. OBJECTIVE: To review the complex anatomy, as well as the authors' approach to executing and interpreting Mohs layers, at each of these anatomical sites. METHODS: A review of the literature on MMS of the eyelid, nose, ear, and genitals was performed using the PubMed database and relevant search terms. CONCLUSION: These sites present potential pitfalls for tumor resection and reconstruction, but with the proper technique, the dermatologic surgeon can minimize tumor recurrence and MMS complications. Warning signs for potentially difficult tumor resection can signify when an interdisciplinary approach is warranted.

Diversity and Career Goals of Graduating Allopathic Medical Students Pursuing Careers in Dermatology.

Importance: Dermatology is one of the least diverse specialties, while patients from minority racial and ethnic groups and other underserved populations continue to face numerous dermatology-specific health and health care access disparities in the US. Objectives: To examine the demographic characteristics and intended career goals of graduating US allopathic medical students pursuing careers in dermatology compared with those pursuing other specialties and whether these differ by sex, race and ethnicity, and/or sexual orientation. Design, Setting, and Participants: This secondary analysis of a repeated cross-sectional study included 58 077 graduating allopathic medical students using data from the 2016 to 2019 Association of American Medical Colleges Graduation Questionnaires. Main Outcomes and Measures: The proportion of female students, students from racial and ethnic groups underrepresented in medicine (URM), and sexual minority (SM) students pursuing dermatology vs pursuing other specialties. The proportions and multivariable-adjusted odds of intended career goals between students pursuing dermatology and those pursuing other specialties and by sex, race and ethnicity, and sexual orientation among students pursuing dermatology. Results: A total of 58 077 graduating students were included, with 28 489 (49.0%) female students, 8447 (14.5%) URM students, and 3641 (6.3%) SM students. Female students pursuing dermatology were less likely than female students pursuing other specialties to identify as URM (96 of 829 [11.6%] vs 4760 of 27 660 [17.2%]; P < .001) or SM (16 [1.9%] vs 1564 [5.7%]; P < .001). In multivariable-adjusted analyses, students pursuing dermatology compared with other specialties had decreased odds of intending to care for underserved populations (247 of 1350 [18.3%] vs 19 142 of 56 343 [34.0%]; adjusted odd ratio [aOR], 0.40; 95% CI, 0.35-0.47; P < .001), practice in underserved areas (172 [12.7%] vs 14 570 [25.9%]; aOR, 0.40; 95% CI, 0.34-0.47; P < .001), and practice public health (230 [17.0%] vs 17 028 [30.2%]; aOR, 0.44; 95% CI, 0.38-0.51; P < .001) but increased odds of pursuing research (874 [64.7%] vs 29 121 [51.7%]; aOR, 1.76; 95% CI, 1.57-1.97; P < .001) in their careers. Among students pursuing dermatology, female, URM, and SM identities were independently associated with increased odds of caring for underserved populations (eg, URM: aOR, 4.05; 95% CI, 2.83-5.80) and practicing public health (eg, SM: aOR, 2.55; 95% CI, 1.51-4.31). URM students compared with non-URM students pursuing dermatology had increased odds of intending to practice in underserved areas (aOR, 3.93; 95% CI, 2.66-5.80), and SM students compared with heterosexual students pursuing dermatology had increased odds of intending to become medical school faculty (aOR, 1.60; 95% CI, 1.01-2.57), to pursue administrative roles (aOR, 1.60; 95% CI, 1.01-2.59), and to conduct research (aOR, 1.73; 95% CI, 1.01-2.98). Conclusions and Relevance: The findings of this cross-sectional study suggest that diversity gaps continue to exist in the dermatology workforce pipeline. Efforts are needed to increase racial and ethnic and sexual orientation diversity and interest in careers focused on underserved care and public health among students pursuing dermatology.

Periosteal flaps allow for single stage reconstruction of larger full thickness eyelid defects: a retrospective study.

Full-thickness lower eyelid defects after Mohs micrographic surgery are frequently referred out to oculoplastic surgery for reconstruction. Reconstructive options include wedge closure with or without canthotomy/cantholysis and tarsoconjunctival sliding flaps. Defects > 50% of the eyelid margin have traditionally required the two-stage Hughes flap, leaving the patient with monocular vision for 3-6 weeks until pedicle division. To demonstrate single-stage periosteal flaps performed by dermatologic surgeons can result in safe, functional, and cosmetically acceptable repairs for large full thickness eyelid defects, an institutional review board-approved retrospective study of repairs performed by two dermatologic surgeons between January 2017 and July 2021 at the University of Minnesota. Patient demographics, operative notes, and follow-up notes were reviewed. Defect and follow-up photographs were scored using a visual analogue scale to assess aesthetic results. Ten cases were included in the analysis. Six patients were male and the average age was 62 years old. 8/10 were basal cell carcinoma and 2/10 were melanoma. The mean defect was 9.5 cm2, with a range of 1-24 cm2. The median cosmetic score was 85.8 ± 10.7. There were no serious complications reported. Mohs micrographic surgeons can safely and successfully reconstruct large, full thickness eyelid defects by periosteal flap.
