RESUMEN
BACKGROUND: Flap repair provides unique advantages in facial reconstruction but still carries the potential for undesirable postoperative cosmetic changes. OBJECTIVE: The aims of this study were to describe postoperative vascular outcomes of patients undergoing flap repairs after Mohs micrographic surgery on facial tumors and to assess associations of baseline characteristics with outcomes. MATERIALS AND METHODS: In this study, 7 dermatologists and 1 physician assistant in dermatology assessed preoperative and postoperative photographs of 57 patients who underwent facial Mohs micrographic surgery, evaluating vascular and pigment outcomes and number of telangiectasias. RESULTS: There was a significant difference in number of telangiectasias according to body location (p = .002), where the number of telangiectasias was highest for nose surgery. CONCLUSION: These data suggest that nasal flap repairs are associated with increased postoperative vascular changes. This highlights an opportunity for improved preoperative patient counseling and possible early laser treatment after nasal Mohs micrographic surgery.
RESUMEN
BACKGROUND: Mohs surgery (MS) is the gold standard for treating nonmelanoma skin cancers in cosmetically sensitive areas. OBJECTIVE: To investigate MS costs over time when adjusting for medical inflation while considering the perspective of patients, payers, and health care systems. METHODS: A retrospective claim analysis using data from the International Business Machines MarketScan Commercial Claims and Encounters Database from 2007 through 2019 was performed. A query of the database for any instance of a MS-specific Current Procedural Terminology (CPT) code in adults (17311, 17312, 17313, 17314, and 17315) was conducted. Aggregate data per claim regarding coinsurance, total cost, deductible, copay, and insurance payout were provided for each CPT code annually. RESULTS: The total adjusted cost per claim decreased significantly (P < .001) for 4 of the 5 MS-specific CPT codes between 2007 and 2019: 17311 (-25%), 17312 (-15%), 17313 (-25%), and 17314 (-18%). The patient's adjusted out-of-pocket expense increased significantly (P < .0001) for 4 of the 5 MS-specific CPT codes: 17311 (33%), 17312 (45%), 17313 (34%), and 17314 (43%). CONCLUSION: Among the 4 most used MS-specific CPT codes (17311, 17312, 17313, and 17314), the total cost per claim decreased and the patient's out-of-pocket expense increased from 2007 to 2019.

BACKGROUND: Merkel cell carcinoma (MCC) is an aggressive neoplasm with high rates of recurrences. Current guidelines recommend wide local excision (WLE) with 1 to 2 cm margins. However, Mohs micrographic surgery (MMS) offers a potential advantage over WLE because of its ability of sparing healthy tissue and assessing 100% of margins. OBJECTIVE: To systematically evaluate the surgical modalities for the treatment of MCC. MATERIALS AND METHODS: Eligible articles were identified using MEDLINE, Scopus, EMBASE, and Cochrane Library. All available studies investigating surgical treatment of MCC with WLE or MMS were considered. RESULTS: Forty studies met the inclusion criteria. Thirty-one studies described patients treated with WLE, 3 with MMS, and 6 with either WLE or MMS. Subgroup analysis of Stage I MCC showed recurrence rates similar in both surgical modalities with local recurrence rate of 6.8% for WLE versus 8.5% for MMS (p = .64) and a regional recurrence rate of 15.2% for WLE versus 15.3% for MMS (p = .99). CONCLUSION: Overall WLE cases were at a higher stage at presentation. Subgroup analysis showed that MMS is not inferior to WLE excision for the treatment of Stage I MCC and is a reasonable option for anatomic locations where tissue sparing is important.

BACKGROUND: Reconstructing defects on the nose can be challenging. The bilobed transposition flap and the nasalis-based V to Y (NBVY) flaps can be excellent repair options, each with their own advantages and disadvantages. OBJECTIVE: To compare bilobed and NBVY flap scar appearances, postoperative complications, scar revision rates, flap sizes, and relative costs. MATERIALS AND METHODS: We reviewed 95 cases of Mohs surgery defects on the nose repaired with either a bilobed or a NBVY flap from 2010 to 2018 at our institution. Eleven reviewers judged postoperative scar images using a modified visual analog scale. RESULTS: There were no significant differences in reviewer-rated scar appearances, complication rates, or revision rates between bilobed and NBVY flaps. The NBVY flaps were 50% smaller than bilobed flaps, with significantly lower CPT billing codes. The NBVY flaps yielded better scar appearance scores compared with bilobed flaps on highly sebaceous noses. CONCLUSION: The NBVY and bilobed flaps demonstrated similar scar appearance outcomes, but the NBVY flap has several advantages. Compared with the bilobed flap, the NBVY flap is smaller, less expensive, and may yield better cosmetic outcomes in patients with highly sebaceous noses.

ABSTRACT: Cutaneous angiosarcomas may express programmed death ligand-1 (PD-L1) and PD-L1 expression, and the presence of tumor-infiltrating lymphocytes (TILs) correlates with outcome. These observations provide a basis for PD-1/PD-L1 inhibitor therapy. Lymphocyte activation gene 3 (LAG-3) is an inhibitory receptor that interacts with the PD-L1 axis and is considered to be a marker of immune exhaustion. The presence of LAG-3-positive lymphocytes in cutaneous angiosarcoma has not been established. We reviewed 10 cases of treatment naive angiosarcoma of skin and superficial soft tissue and assessed for PD-L1 (ZR3) expression, presence of TILs, and expression of CD8, PD1, and LAG-3 by tumor-associated inflammatory cells by immunohistochemistry. All 10 angiosarcomas were positive for PD-L1: 7 with high expression and 3 with low expression. TILs were present in all tumors: brisk in 7 and nonbrisk in 3. CD8 lymphocytes were present in all tumors with a range of 212-1274 cells per square millimeter (mean 557 CD8 cells/mm2). LAG-3-positive lymphocytes were present in 9 of 10 angiosarcomas with a range of 0-728 cells/mm2 (mean 146 LAG-3 cells cells/mm2). The ratio of LAG-3 lymphocytes to CD8 lymphocytes was 0%-59% (mean 27%). The PD1 cell counts were intermediate between CD8 and LAG3 counts. Cutaneous angiosarcomas frequently express PD-L1, have prominent numbers of CD8 positive, and have smaller numbers of LAG-3-positive and PD-1-positive TILs. Our findings provide further evidence of PD-L1 expression in cutaneous angiosarcoma and the promise for immune checkpoint inhibitor therapy.

BACKGROUND: Reconstruction of large nasal surgical defects often warrant the use of mucosal flaps to repair the inner lining. This often presents a challenge for surgical reconstruction. OBJECTIVE: To describe a unique reconstructive option for the repair of large surgical wounds that necessitate mucosal nasal lining. MATERIALS AND METHODS: This study is a retrospective review of 10 patients who underwent surgical reconstruction of large nasal and/or heminasal surgical defects following Mohs micrographic surgery. A nasolabial turnover interpolation flap was used to repair missing nasal mucosal lining, coupled with a cutaneous flap which typically involved a paramedian forehead flap. The duration of follow-up was 8 months. An aesthetic and functional surgical outcomes measure was used to assess the final repair. RESULTS: Favorable aesthetic outcomes were obtained in all patients and without need of revision surgery by the use of a nasolabial turnover interpolation flap. CONCLUSION: The nasolabial turnover interpolation flap offers a reliable and effective method of repair for large transmural nasal surgical wounds. We typically paired this nasal lining flap with a paramedian forehead flap with reliable and aesthetic outcomes. This technique is straightforward, reproducible, and with both good aesthetic and functional outcomes.

BACKGROUND: Mohs micrographic surgery (MMS) has been used effectively to treat invasive melanoma. OBJECTIVE: To further study the safety and efficacy of MMS in the treatment of invasive melanoma. METHODS AND MATERIALS: A retrospective cohort study evaluated 123 melanomas excised using MMS with MART-1 immunostain. Local recurrence, metastasis, overall survival, and disease-free survival rates were calculated. These were compared with historical controls. RESULTS: Among included patients, 78 were men (63%) and 45 were women (37%), with a mean age of 66.48 years. Mean follow-up time was 1,273 days (3.49 years). Local recurrence was identified in 2/123 (1.63%; 95% confidence interval, 0.20%-5.75%) lesions. Local recurrence was identified in 1/70 (1.43%; 95% confidence interval, 0.04%-7.70%) of head and neck cases. Tumor location was head and neck in 70 lesions (56.9%). Overall survival was 95.12% and disease-specific survival was 100%. CONCLUSION: Mohs micrographic surgery is an effective treatment method for invasive melanoma, as evidenced by low recurrence rates and high rates of disease-free survival.
