Abstract

BACKGROUND:Hispanics are one of the fastest growing populations in the United States. Few studies have characterized the patterns of keratinocyte carcinoma presentation in Hispanics. OBJECTIVE:The study aimed to compare the clinical and histologic characteristics of keratinocyte carcinomas in Hispanics and non-Hispanic whites. MATERIALS AND METHODS:A five-year retrospective chart review was conducted at a single academic center to identify all histologically-confirmed cases of keratinocyte carcinomas. Tumor characteristics were then compared between Hispanics and non-Hispanic whites. RESULTS:A total of 197 tumors were identified of which 76% occurred in non-Hispanic whites and 24% in Hispanics. Tumor diameter was not larger and histologic subtype was not more aggressive in Hispanics compared to non-Hispanic whites. Age of diagnosis of basal cell carcinoma was younger among Hispanics compared to non-Hispanic whites (P < .05). CONCLUSION:Hispanics were not more likely to present with more high-risk keratinocyte carcinomas compared to non-Hispanic whites in terms of tumor diameter, differentiation and subtype.

摘要

背景: 西班牙裔是美国增长最快的人口之一。很少有研究描述西班牙裔人角质形成细胞癌表现的模式。 目的: 本研究旨在比较西班牙裔和非西班牙裔白人角质形成细胞癌的临床和组织学特征。 材料和方法: 在单个学术中心进行了为期 5 年的回顾性图表回顾,以确定所有角质形成细胞癌的组织学确诊病例。然后比较西班牙裔和非西班牙裔白人的肿瘤特征。 结果: 共发现 197 个肿瘤,其中 76% 发生在非西班牙裔白人,24% 发生在西班牙裔。与非西班牙裔白人相比,西班牙裔白人的肿瘤直径并不大,组织学亚型也不更具侵袭性。与非西班牙裔白人相比,西班牙裔白人诊断基底细胞癌的年龄更年轻 (P <.05)。 结论: 与非西班牙裔白人相比,西班牙裔在肿瘤直径、分化程度和亚型方面不太可能出现更多的高危角质形成细胞癌。

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.

皮肤肿瘤方向

皮肤肿瘤是发生在皮肤的细胞增生性疾病,是一种常见病。发生于皮内或皮下组织的新生物,种类很多,临床上分良性肿瘤和恶性肿瘤。恶性肿瘤可以不断增殖,引起转移,威胁生命,称为皮肤癌。
