BACKGROUND:Outcomes for patients with cutaneous squamous cell carcinoma (CSCC) treated with Mohs micrographic surgery (MS) in the United States have never been prospectively defined. Risk factors as they relate to outcomes are primarily derived from single-institution, retrospective data without regard for treatment modality. The American Joint Committee on Cancer Staging Manual, Eighth Edition, and the Brigham and Women's Hospital T staging systems have not been prospectively validated. OBJECTIVE:To prospectively quantify outcomes by T stage and verify historically high-risk features as they pertain to outcomes in MS-treated CSCC. METHODS:A 5-year, prospective, multicenter analysis of patients undergoing MS for invasive CSCC was conducted. RESULTS:The study enrolled 647 patients with 745 tumors. The 5-year local recurrence (LR)-free survival, nodal metastasis (NM)-free survival, and disease-specific survival were 99.3%, 99.2%, and 99.4%, respectively. Both staging systems were predictive of NM, disease-specific death, and all-cause death; neither was predictive of LR. Although Breslow depth was statistically associated with LR, NM, and disease-specific death, incidental perineural invasion was not. LIMITATIONS:The Brigham and Women's Hospital and the American Joint Committee on Cancer Staging Manual, Eighth Edition T staging systems were published after study enrollment, therefore T stages were retrospectively applied using the prospectively collected data. CONCLUSION:MS is a highly effective treatment for CSCC and may mitigate factors typically considered high risk. Uniform reporting of Breslow depth should be considered in CSCC. The American Joint Committee on Cancer Staging Manual, Eighth Edition, and the Brigham and Women's Hospital staging system are useful prognosticators but are not predictive of LR after MS.

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.
