Abstract
ZusammenfassungHintergrund und ZieleDie Melanom‐Leitlinie basiert hauptsächlich auf dem AJCC‐Stadium. Hierbei wird nicht zwischen den histologischen Subtypen wie dem superfiziell spreitenden Melanom (SSM), dem Lentigo‐maligna‐Melanom (LMM) oder dem nodulären malignen Melanom (NM) unterschieden. Ziel der Studie war es zu untersuchen, ob sich Patienten mit LMM im klinischen Verlauf von Patienten mit SSM/NM unterscheiden. Dies ist aktuell besonders wichtig, da die adjuvante Anti‐PD‐1‐Therapie für Melanome im Stadium IIB und IIC zugelassen wurde.Patienten und MethodikDie Daten wurden aus dem Zentralregister „malignes Melanom“ entnommen. Es wurden nur Patienten mit LMM, SSM oder NM des Kopf‐Hals‐Bereichs und Primärdiagnose zwischen dem 01.01.2000 und dem 31.12.2019 eingeschlossen. Das progressionsfreie Überleben (PFÜ), das melanomspezifische Überleben (MSÜ) und das Metastasierungsmuster wurden für die Gruppe der LMM im Vergleich zur Gruppe der SSM/NM analysiert.ErgebnisseDie LMM‐Kohorte (n = 902) hatte ein signifikant besseres MSÜ als die SSM/NM‐Kohorte (n = 604). Beim PFÜ gab es keinen Unterschied. Das 5‐Jahres‐MSÜ der LMM‐Kohorte im Stadium II betrug 88,5 % (95 % KI 81,4–95,6), im Vergleich dazu das der SSM/NM‐Kohorte im Stadium II 79,7 % (95 % KI 72,8–86,6).SchlussfolgerungEs scheint nicht angebracht zu sein, eine adjuvante Therapie bei LMM‐Patienten im Stadium II im gleichen Umfang durchzuführen, wie bei Patienten mit SSM/NM.

Abstract
BACKGROUND AND OBJECTIVES The melanoma guideline is mainly based on the AJCC stage. There is no difference according to histological subtypes such as superficial spreading melanoma (SSM), lentigo maligna melanoma (LMM) or nodular malignant melanoma (NM). We aimed to evaluate whether patients with LMM have a different clinical course from patients with SSM/NM. This is particularly important as adjuvant anti-PD-1 therapy is approved for stage IIB and IIC melanoma. PATIENTS AND METHODS Data were extracted from the Central Registry of Malignant Melanoma. Only patients with LMM, SSM, and NM of the head and neck with primary diagnosis between 01/01/2000 and 12/31/2019 were included. Progression-free survival (PFS), melanoma-specific survival (MSS), and pattern of metastases were analyzed for the LMM group compared to SSM/NM. RESULTS The LMM cohort (n = 902) had significantly better MSS than the SSM/NM cohort (n = 604). There was no difference in PFS. The 5-year MSS of the stage II LMM cohort was 88.5% (95% CI 81.4-95.6) compared to 79.7% (95% CI 72.8-86.6) in the stage II SSM/NM cohort. CONCLUSION It does not appear appropriate to use adjuvant therapy in stage II LMM patients to the same extent as in patients with SSM/NM.

Abstract
Importance The management of lentigo maligna (LM) and LM melanoma (LMM) is challenging because of extensive subclinical spread and its occurrence on cosmetically sensitive areas. Reflectance confocal microscopy (RCM) improves diagnostic accuracy for LM and LMM and can be used to delineate their margins. Objectives To evaluate whether handheld RCM with radial video mosaicing (HRCM-RV) offers accurate presurgical assessment of LM and LMM margins. Design, Setting, and Participants This prospective study included consecutive patients with biopsy-proven LM and LMM located on the head and neck area who sought consultation for surgical management from March 1, 2016, through March 31, 2017, at the Dermatology Service of the Memorial Sloan Kettering Cancer Center. Thirty-two patients underwent imaging using HRCM-RV, and 22 patients with 23 LM or LMM lesions underwent staged surgery and contributed to the analysis. Main Outcomes and Measures Clinical lesion size and area, LM and LMM area based on HRCM-RV findings, surgical defect area estimated by HRCM-RV, and observed surgical defect area. In addition, the margins measured in millimeters estimated for tumor clearance in each quadrant based on HRCM-RV findings were calculated and compared with the surgical margins. Results Among the 22 patients (12 men and 10 women; mean [SD] age, 69.0 [8.6] years [range, 46-83 years]) with 23 lesions included in the final analysis, the mean (SD) surgical defect area estimated with HRCM-RV was 6.34 (4.02) cm2 and the mean (SD) area of surgical excision with clear margins was 7.74 (5.28) cm2. Overall, controlling for patient age and previous surgery, surgical margins were a mean of 0.76 mm (95% CI, 0.67-0.84 mm; P < .001) larger than the HRCM-RV estimate. Conclusions and Relevance Mapping of LM and LMM with HRCM-RV estimated defects that were similar to but slightly smaller than those found in staged excision. Thus, mapping of LM using HRCM-RV can help spare healthy tissue by reducing the number of biopsies needed in clinically uncertain areas and may be used to plan treatment of LM and LMM and counsel patients appropriately.

Abstract
BACKGROUND Lentigo maligna (LM) is the in situ phase of lentigo maligna melanoma (LMM). A wide variety of modalities has been used to manage LM, including conventional surgery, staged excision, Mohs micrographic surgery, cryotherapy, radiotherapy, laser therapy, and, recently, imiquimod. OBJECTIVES Soft x-radiation is an accepted treatment for LM/LMM. The aim of the present study was to evaluate the efficacy and safety of ultra-soft x-ray/grenz-ray (GR) treatment in patients with LM and early LMM. METHODS Five hundred ninety-three patients were treated with GR (primary therapy, n = 350; partial excision followed by GR, n = 71; radical excision followed by GR as recurrence-prophylactic treatment, n = 172) at the Department of Dermatology, Karolinska University Hospital, Stockholm, Sweden between 1990 and 2009. The treatment was given twice a week over 3 consecutive weeks in total doses of 100 to 160 Gy. Dosage depended on the stage of LM and the depth of periadnexal atypical melanocytic extension in histologically examined materials before treatment. Four hundred twenty-five patients have been followed up for at least 2 years; of these, 241 for 5 years. RESULTS Overall, 520 of 593 patients (88%) showed complete clearance after one fractionated treatment. Residual lesions were seen in 15 patients, and 58 relapsed, 53 of whom (72%) within 2 years. LIMITATION Woods light examination was not used in the clinical diagnosis of lentigo maligna. CONCLUSIONS GR is an efficient and safe treatment in LM and early LMM when administered according to the recommendations presented herein. Moreover, GR offers an excellent cosmetic result.

Abstract
Limited studies have reported the in vivo reflectance confocal microscopy (RCM) features of lentigo maligna (LM). A total of 64 RCM features were scored retrospectively and blinded to diagnosis in a consecutive series of RCM sampled, clinically equivocal, macules of the face (n=81 LM, n=203 benign macules (BMs)). In addition to describing RCM diagnostic features for LM (univariate), an algorithm was developed (LM score) to distinguish LM from BM. This comprised two major features each scoring +2 points (nonedged papillae and round large pagetoid cells > 20 microm), and four minor features; three scored +1 point each (three or more atypical cells at the dermoepidermal junction in five 0.5 x 0.5 mm(2) fields, follicular localization of atypical cells, and nucleated cells within the dermal papillae), and one (negative) feature scored -1 point (a broadened honeycomb pattern). A LM score of > or = 2 resulted in a sensitivity of 85% and specificity of 76% for the diagnosis of LM (odds ratio (OR) for LM 18.6; 95% confidence interval: 9.3-37.1). The algorithm was equally effective in the diagnosis of amelanotic lesions and showed good interobserver reproducibility (87%). In a test set of 29 LMs and 44 BMs, the OR for LM was 60.7 (confidence interval: 11.9-309) (93% sensitivity, 82% specificity).

Abstract
BACKGROUND Wide local excision of primary cutaneous melanoma usually provides clear margins and excellent local control. Nonclassical presentations of cutaneous melanoma, however, can challenge this treatment algorithm. Specifically, persistent melanoma-in-situ (MIS) at the margin not suspected clinically makes planning definitive wide local excision more difficult. We hypothesized that the use of punch biopsies as a mapping tool would allow us to obtain clear margins in these challenging cases. METHODS Punch biopsies were performed at sites 1 to 2 cm from prior positive margins. Subsequent wide local excision was planned, including all punch biopsy sites with positive findings: atypical melanocytic hyperplasia, MIS, or invasive melanoma. The management of three patients was documented prospectively. Standard surgical techniques were used independent of an experimental protocol. Medical records were reviewed, and data were summarized under institutional review board protocol HIC 10803. RESULTS The results of punch biopsies identified invasive melanoma, MIS, or atypical melanocytic hyperplasia in all three patients with MIS at the margins. All three mapping procedures were well tolerated and resulted in resection with negative margins in a single definitive resection. CONCLUSION Melanoma mapping with punch biopsy technique allows for definitive excision in cases when disease persists at the margins of the reexcision or in cases with unclear clinical examinations.

Abstract
BACKGROUND Extramammary Paget's disease (EMPD) frequently extends subclinically, resulting in high recurrence rates after surgical excision. Mohs micrographic surgery (MMS) improves cure rates but may require time-consuming reexcision of subclinical extension. A mechanism to estimate the location and extent of subclinical extension would be helpful. OBJECTIVE To describe and evaluate a technique for multiple scouting biopsies before MMS for EMPD. METHOD A retrospective review of patients at Mayo Clinic who had multiple scouting biopsies before MMS for EMPD without dermal invasion. TECHNIQUE The clinical extent of EMPD is identified. The scouting biopsy sites are determined and documented with photographs. The scouting biopsy specimens are sent for permanent sections. The results of the scouting biopsies help guide the extent of the initial Mohs layer. The tumor is cleared with MMS. An additional 1 mm peripheral margin of tissue is usually submitted for permanent sections. RESULTS Multiple scouting biopsies were done in five patients. Four of the five patients had at least one true-positive result. At least one true-negative result was obtained in all five patients. Two patients had at least one false-negative result. CONCLUSION Multiple scouting biopsies before MMS for EMPD without dermal invasion can be a beneficial adjuvant technique.
