Abstract

AIMS:In previous studies, skin retraction of dermato-pathological specimens after the surgical excision of tumours was calculated at 30% for the surface, with approximately 20% for the length and 15% for the width. The aim of this study was to analyse the retraction of the specimens and the retraction of the lesion and the margins. METHODS:Patients who underwent excision of a skin tumour between January 2013 and July 2014 were randomly included. RESULTS:A total of 104 patients was included. There were 52% male with a mean age of 68.3 years. Seventy-eight per cent of the lesions were malignant (51% were basal cell carcinoma, 10% squamous cell carcinoma). The retraction of the area of the specimen (29%) was significantly greater than the retraction of the tumour (21%). On multivariate analysis, the localisation and the duration of fixation were independent predictors of the specimen area retraction. The retraction of the specimen was 17% in length and 15% in width. The retraction of the margins was calculated at 19% in length and 12% in width. The surgeon correctly evaluated the localisation of the smallest margin in 55% of cases. CONCLUSIONS:Our study provided additional data regarding the retraction of the tumours and margins. The guidelines for surgical excision of skin cancers recommend a clinical margin before excision, but the evaluation of the sufficiency of the margins is based on histological measurement. Our data are useful for the interpretation of the sufficiency of the margins.

摘要

目的: 在以前的研究中,皮肤病理标本在肿瘤手术切除后的皮肤回缩计算为表面 30% mm,长度约为 20% mm,宽度约为 15% mm。本研究的目的是分析标本的回缩以及病变和边缘的回缩。 方法: 随机纳入 2013 年 1 月至 2014 年 7 月接受皮肤肿瘤切除术的患者。 结果: 共纳入 104 例患者。男性 52% 例,平均年龄 68.3 岁。51% 的病变为恶性 (10% 为基底细胞癌,为鳞状细胞癌)。标本面积的回缩 (29%) 明显大于肿瘤的回缩 (21%)。在多变量分析中,定位和固定持续时间是标本面积回缩的独立预测因素。试样的回缩长度为 17%,宽度为 15%。边缘的回缩计算为长度 19%,宽度 12%。外科医生在 55% 的病例中正确评估了最小切缘的定位。 结论: 我们的研究提供了关于肿瘤和边缘回缩的额外数据。皮肤癌手术切除指南推荐切除前的临床切缘,但切缘充分性的评价是基于组织学测量。我们的数据对于解释利润的充分性是有用的。

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。
