OBJECTIVE:Although basal cell carcinoma (BCC) is the most common skin cancer, locally aggressive BCC of the head and neck is rare and not well studied. STUDY DESIGN:Retrospective review of patients who underwent primary surgical resection of locally aggressive head and neck BCC at a single tertiary academic center. RESULTS:Eighty-seven patients with 98 tumors demonstrated a 5-year Kaplan-Meier estimated recurrence-free survival of 64.5%, overall survival of 83.3%, and disease-specific survival of 98.3%. Intraoperative positive frozen section margin was a strong independent predictor of local recurrence (hazard ratio 6.88, P = 0.038) and was more likely to occur in tumors previously treated with radiation (odds ratio 6.47 = 0.05). CONCLUSION:Locally aggressive BCCs of the head and neck have high rates of local recurrence but low disease-specific mortality when treated with primary surgery and selected use of adjuvant therapy. Intraoperative positive frozen section margin is a strong independent predictor of local recurrence and is more likely in tumors that were previously treated with radiation therapy.

目的: 虽然基底细胞癌 (BCC) 是最常见的皮肤癌,但头颈部局部侵袭性BCC罕见,研究尚不充分。 研究设计: 回顾性审查在单个三级学术中心接受局部侵袭性头颈部BCC一期手术切除的患者。 结果: 87 例 98 个肿瘤患者的 5 年Kaplan-Meier估计无复发生存率为 64.5%,总生存率为 83.3%,疾病特异性生存率为 98.3%。术中冰冻切缘阳性是局部复发的强独立预测因子 (风险比 6.88,P = 0.038) 且更可能发生在既往接受放射治疗的肿瘤中 (比值比 6.47 = 0.05)。 结论: 头颈部局部侵袭性BCCs在初次手术和选择辅助治疗时局部复发率高,但疾病特异性死亡率低。术中冰冻切缘阳性是局部复发的强独立预测因子,在既往接受过放射治疗的肿瘤中更有可能。 证据级别: 4 喉镜,130:115-119,2020。

METHODS::Blue rubber bleb naevus syndrome (BRBNS) is an extremely rare venous malformation that often manifests as multiple haemangioma-like lesions in the skin and gastrointestinal tract. The drug sirolimus plays a key role in the signalling pathway of angiogenesis and subsequent development of BRBNS and its use has been described in several case reports. We present a case series of four patients with BRBNS who exhibited good treatment response to sirolimus. All four patients were administered oral sirolimus at doses of 1.0-1.5 mg/m2 /day with a target drug level of 5-10 ng/mL and median treatment duration of 20 months. All patients had a reduction in the size of the lesions and a normalization of coagulopathy with tolerable drug adverse reactions at follow-up. Sirolimus may be effective and safe in paediatric patients with BRBNS. Further prospective studies are suggested to evaluate the long-term effectiveness of this drug.

METHODS:BACKGROUND:Human papillomavirus (HPV) infections are associated with common dermatologic and nondermatologic diseases. Although HPV vaccines are well established as preventive measures for genital warts and cervical neoplasia, their use as therapeutic agents deserves greater attention. OBJECTIVE:To evaluate the use of HPV vaccine(s) as a treatment modality for cutaneous and/or mucosal disease. METHODS:A primary literature search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted in January 2019 by using the PubMed and Cochrane databases. RESULTS:A total of 63 articles with 4439 patients were included. The majority of patients with cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas were successfully treated with HPV vaccination. Preliminary data on patients with pre-existing anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia is promising. LIMITATIONS:This review was limited by the lack of controls, patients' previous HPV vaccination status, and publication bias. CONCLUSION:The commercially available three-dose, quadrivalent HPV vaccine is a potential therapeutic option for the treatment of cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas. Noncommercially available HPV vaccines demonstrate therapeutic response for treating anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia. The vaccine's efficacy as an adjunct therapy for HPV-associated cutaneous and/or mucosal disease warrants further exploration.

METHODS::Our understanding of melanoma precursors and progression to melanoma has developed as a result of advances in the field of molecular diagnostics. We now better understand the potential for genetic heterogeneity within a single lesion. Combined tumors can pose a diagnostic challenge when deciding the line between benign and malignant, which in turn has direct implications for patient management. Primary cilia (PC) are ubiquitous sensory organelles that have essential functions in cellular proliferation, differentiation, and development. The ciliation index (percentage of ciliated melanocytes) has been shown to reliably differentiate melanoma, which fail to ciliate, from melanocytic nevi, which retain PC. We therefore analyzed the potential for using the ciliation index to differentiate benign and malignant components in combined melanocytic lesions. We collected patient samples (n = 10) of unequivocal combined lesions with both melanoma and associated nevus components. Melanocytes were highlighted with SOX10 and costained with gamma-Tubulin and acetylated alpha-Tubulin to highlight the basal body and cilium, respectively. The number of melanocytes retaining cilia under high-power microscopy was examined. The melanoma component had average of 4% ciliation (SD: 7%), whereas the associated nevus component was significantly higher with 59% ciliation (SD: 17%). These data show that PC may be a reliable means of distinguishing benign from malignant components within a single tumor. The ciliation index may be a helpful tool in distinguishing challenging cases of combined lesions of melanoma in situ with a dermal nevus component from invasive melanoma, thus promoting improved staging and clinical management.
