[症例1]は18歳女性。アトピー性皮膚炎。体温上昇によって眼瞼腫脹が出現した。[症例2]は20歳女性。アトピー性皮膚炎。体温上昇によって眼瞼腫脹、アナフィラキシーが出現した。2症例とも補体は正常で、血管浮腫の家族歴はなく、蕁麻疹の合併もなかったため、体温上昇によって誘発された血管浮腫と考えた。入浴や運動による血管浮腫、アナフィラキシー、コリン性蕁麻疹はアトピー性皮膚炎を有する若年女性に好発するとされている。我々の症例はコリン性蕁麻疹の合併がなかったが経過を追いたい。(著者抄録)

　概要を見る

The immune checkpoint inhibitor nivolumab inhibits the programmed death 1 receptor and suppresses the immune resistance of cancer cells. This is a long-term follow up of a single-arm, open-label, multicenter, phase II study of nivolumab in untreated Japanese patients with stage III/IV or recurrent melanoma. In addition, a post-hoc subgroup analysis stratified by melanoma types was performed. Nivolumab was administered intravenously at a dose of 3 mg/kg every 2 weeks. The primary endpoint was the overall response rate (ORR), and secondary endpoints included overall survival (OS), progression-free survival (PFS), best overall response, the disease control rate and change in tumor diameter. Safety was assessed by recording treatment-related adverse events (TRAE), including select immune-related adverse events. Of the 24 patients initially included in the primary phase II study, 10 survived for over 3 years (41.7%). The ORR was 34.8% (90% confidence interval [CI]: 20.8, 51.9) for all patients. When analyzing by melanoma type, the ORR was 66.7% (90% CI: 34.7, 88.3) for superficial spreading, 33.3% (90% CI: 11.7, 65.3) for mucosal, and 28.6% (90% CI: 10.0, 59.1) for acral lentiginous tumors. The median OS was 32.9 months, the 3-year OS rate was 43.5%, and the 3-year PFS rate was 17.2%. A long-term response was observed in all the tumor types. The most common TRAE included skin toxicity (45.8%) and endocrine disorders (29.2%). This study demonstrated the long-term efficacy and tolerability of nivolumab in patients with advanced or recurrent melanoma, irrespective of melanoma type.

Importance: It is challenging to differentiate melanoma from melanocytic nevus on the volar skin in the absence of typical dermoscopic patterns. Objective: To identify the frequency and clinical and dermoscopic characteristics of melanocytic lesions on the volar skin not displaying a parallel furrow pattern, lattice-like pattern, fibrillar pattern, or parallel ridge pattern on results of dermoscopy. Design, Setting, and Participants: In this retrospective cohort study, a total of 504 melanocytic lesions on the volar skin were evaluated in the Shinshu University Hospital department of dermatology between January 1, 2000, and December 31, 2012. Dermoscopic images were independently assessed by 3 dermoscopists for the presence of established dermoscopic criteria. Statistical analysis was performed from October 1, 2017, to April 30, 2018. Main Outcomes and Measures: Frequency of dermoscopic criteria and corresponding clinical (patient age and size and location of lesion) and histopathologic features. Results: Of 504 lesions, 110 (21.8%) (melanocytic nevus, 97; melanoma, 8; and equivocal melanocytic lesion, 5) from 108 patients (68 female and 40 male patients; mean age, 40.1 years [range, 1-86 years]) did not show a parallel furrow pattern, lattice-like pattern, fibrillar pattern, or parallel ridge pattern. Among them, the mean patient age was significantly higher for melanoma than for melanocytic nevus (65.3 vs 38.0 years; P < .001), as was mean maximum lesion diameter (11.8 vs 5.7 mm; P < .001). Melanomas and equivocal melanocytic lesions tended to be distributed on weight-bearing areas of the foot sole, such as the heel, while nevi were spread over non-weight-bearing regions. Dermoscopically, 95 melanocytic nevi (97.9%) were symmetrical in 1 or 2 axes while melanomas were not. A total of 91 melanocytic nevi (93.8%) had 1 or 2 colors per lesion, and 4 melanomas (50.0%) had more than 2 colors. Vascular structures were seen in 3 melanocytic nevi (3.1%) and 3 melanomas (37.5%). Blue-white structures were seen in 18 melanocytic nevi (18.6%) and 3 melanomas (37.5%). Dots and globules were seen in 22 melanocytic nevi (22.7%) and 4 melanomas (50.0%). Vascular structures, blue-white structures, and dots and globules were irregularly distributed in the melanomas. Ulcer, hyperkeratosis, and irregular streaks were observed only in melanomas. Conclusions and Relevance: More than one-fifth of melanocytic lesions on the volar skin did not display typical dermoscopic patterns. Asymmetry, numerous colors (≥3), and other melanoma-specific dermoscopic findings were more frequently observed for melanomas. Clinical information, including patient age and lesion size and location, was helpful in differentiating melanoma from melanocytic nevus. Further prospective clinical studies are warranted to clarify the diagnostic accuracy of dermoscopy combined with clinical information.

Some studies showed that clinical response to immune check point inhibitors is lower in acral and mucosal melanoma than in cutaneous melanoma. Although the synergistic effect of radiotherapy (RT) and ipilimumab has been reported in patients with brain metastasis, the efficacy of combined RT and anti-programmed death 1 (PD-1) therapy for acral and mucosal melanoma is unclear. The present study aimed to evaluate the efficacy of combined RT and anti-PD-1 therapy for acral and mucosal melanoma. We retrospectively analyzed patients with acral or mucosal melanoma who were treated with anti-PD-1 and RT at Sapporo Medical University Hospital. In 10 patients (acral, 3; mucosal, 7), the response rate (RR) and the disease control rate (DCR) were 40% and 60%, respectively. As regards mucosal melanoma, four of the seven patients had achieved complete response + partial response, and three had progressive disease (RR = 57.1%). Meanwhile, two of the three patients with acral melanoma had stable disease and one had progressive disease (RR and DCR were 0% and 66.6%, respectively). Except for the patients treated with palliative RT for bone metastasis in the present study, the RR was 50% (4/8 patients), and the DCR was 75% (6/8 patients). Vitiligo developed after RT in five (50%) patients at a median duration of 2 months after RT. The clinical response and the high occurrence of vitiligo suggest that the combination of RT and anti-PD-1 therapy could be effective in some patients with mucosal melanoma.
