ABSTRACT The American Board of Dermatology (ABD) Continuing Certification Program (CCP) for board‐certified dermatologists helps advance its vision, which includes quarterly web‐based knowledge assessments. In 2022, the ABD began a review of gaps in knowledge assessment, practice improvement reporting, and areas of educational interest. The American Board of Medical Specialties directed member boards to share frequently occurring deficits with specialty societies to identify and prioritize gaps. This report summarizes pediatric dermatology findings from this review.

AbstractBackgroundRisk factors for local atypical fibroxanthoma (AFX) recurrence and progression to pleomorphic dermal sarcoma (PDS) have not previously been identified.ObjectiveTo identify risk factors and provide follow‐up suggestions for local AFX recurrence and progression to PDS.Methods and MaterialsA literature search was performed in the PubMed, EMBASE, and Cochrane databases. The PRISMA and MOOSE guidelines were followed. The risks of local AFX recurrence and progression to PDS were presented as Kaplan–Meier plots and risk factors were presented as hazard ratios (HRs) calculated with univariate and multivariate Cox regression.ResultsFive hundred and ninety‐eight patients with AFX from 14 studies were included. Age >74 years and male sex significantly increased the risk of local recurrence (HR: 7.31 [95% confidence interval [CI]: 1.78–30.0], p < 0.01 and HR: 2.89 [95% CI: 1.04–8.01], p < 0.05, respectively). There was no difference when comparing wide local excision and Mohs' micrographic surgery (p = 0.89). The risks of local AFX recurrence and progression to PDS after 2 years were <1%.ConclusionA more intensive follow‐up regimen could be considered in patients >74 years old and males due to the higher risk of local AFX recurrence.

BACKGROUND Perioperative anxiety can negatively impact patient satisfaction and can complicate outpatient dermatologic procedures. OBJECTIVE Evaluate adverse events associated with oral midazolam as a perioperative anxiolytic during dermatologic surgery and assess whether an enhanced monitoring approach is associated with an increased detection rate. MATERIALS AND METHODS Five hundred cases (250 before and after change in monitoring) where patients were administered oral midazolam between July 2015 and May 2017 were retrospectively reviewed. The number of procedures, type of procedures, dose in milligrams, number of doses, major and minor adverse events, and vital signs were recorded. RESULTS The difference in number of treatment sites, types of procedures, and total dose administered was not significant. There were minor but significant differences in the mean change in blood pressure, heart rate, respiratory rate, and Richmond Agitation and Sedation Scale score before and after the procedure but not oxygen saturation. These vital sign changes were not clinically significant. There were zero major adverse events in both groups. There were 2 patients who became transiently hypoxic. CONCLUSION Oral midazolam administration was not associated with major adverse events including in the more intensively monitored group. This supports its use as an anxiolytic for outpatient dermatologic procedures.

BACKGROUND Extramammary Paget disease (EMPD) is a rare intraepithelial adenocarcinoma occurring mainly in the anogenital region. Traditional management with wide local excision has shown high recurrence rates, thus Mohs micrographic surgery (MMS) has emerged as a promising treatment option. OBJECTIVE To compare long-term outcomes after treatment with MMS or excision for primary EMPD. METHODS AND MATERIALS Retrospective cohort review was conducted for 207 patients with EMPD treated at Mayo Clinic in Rochester, MN, between 1961 and 2012. RESULTS Of the 25 patients treated with MMS, 19 primary tumors were included for outcome analysis, with an estimated 5-year recurrence-free survival rate of 91% (95% confidence interval [CI], 75–100) using Kaplan–Meier curve analysis. Of 158 patients treated with local excision, 124 were included for the analysis, with an estimated 5-year recurrence-free survival rate of 66% (95% CI, 56–78). The hazard ratio (HR) for association of treatment was 0.4 (95% CI, 0.10–1.65; p = .20). Estimated 5-year overall survival rates were 79% for MMS (95% CI, 61–100) and 68% for excision (95% CI, 59–78) (HR, 1.39 [95% CI, 0.69–2.82]; p = .36). CONCLUSION Although treatment of primary EMPD with MMS versus excision did not show statistical difference, MMS demonstrated favorable long-term outcomes and was associated with a higher recurrence-free survival rate.

BACKGROUND Dermatofibrosarcoma protuberans (DFSP) is a soft tissue tumor with slow infiltrative growth and local recurrence if inadequately excised. OBJECTIVE To compare long-term outcomes after Mohs micrographic surgery (MMS) and wide local excision (WLE). MATERIALS AND METHODS Records of patients with DFSP surgically treated with WLE or MMS from January 1955 through March 2012 were retrospectively reviewed. RESULTS Mean follow-up for patients treated with MMS (n = 67) and WLE (n = 91) was 4.8 and 5.7 years, respectively. Twenty-eight patients (30.8%) with WLE had recurrence (mean, 4.4 years), whereas only 2 (3.0%) with MMS had recurrence (1.0 and 2.6 years). Recurrence-free survival rates at 1, 5, 10, and 15 years were significantly higher with MMS (p < .001). Mean preoperative lesion sizes were similar (5–6 cm) between the 2 groups, whereas mean (standard deviation) postoperative defect sizes were 10.7 (4.3) cm and 8.8 (5.5) cm for WLE and MMS, respectively (p = .004). Primary closure was used for 73% of MMS cases, whereas WLE more commonly used flaps, grafts, or other closures (52%). Two Mohs layers typically were required for margin control. CONCLUSION Surgical excision with meticulous histologic evaluation of all surgical margins is needed for DFSP treatment to achieve long-term high cure rates and low morbidity.

BACKGROUND Hidradenitis suppurativa (HS) is a progressive, recurrent inflammatory disorder. OBJECTIVE To assess long-term satisfaction and postoperative perceptions among patients who underwent surgical management of HS. MATERIALS AND METHODS A questionnaire was mailed to 499 HS surgical patients to assess surgical outcome, satisfaction, and quality of life. RESULTS Of the 499 questionnaires mailed, 113 were returned (22.6% response rate) and 2 were excluded for redundancy. Of the 111 respondents, 65 (58.6%) were female, 91 (82.0%) had Hurley Stage III disease, 88 (79.3%) were treated with excision and 23 (20.7%) with unroofing, 45 (40.5%) had perianal or perineal disease, and 41 (36.9%) had axillary disease. Most patients were satisfied or very satisfied with their surgical results (84.7%; 94 of 111), were glad they underwent surgery (96.3%; 105 of 109), and would recommend surgery to a friend or relative (82.6%; 90 of 109). Most patients were satisfied or very satisfied with the appearance of their healed wound (62.4%; 68 of 109). Retrospective mean quality of life increased significantly from 5 preoperatively to 8.4 postoperatively (p < .001). CONCLUSION Hidradenitis suppurativa surgical management was well regarded by patients and should be considered by future patients to limit the morbidity of HS.
