    目的:比较全厚度皮肤移植和裂层皮肤移植在头皮重建中的应用。
    方法:回顾性图表回顾了2011年至2016年在一家机构进行的皮肤移植头皮重建的患者。
    方法:使用χ2或Fisher精确检验比较移植物整合和并发症发生率。移植物类型的影响,缺陷类型,移植物大小,采用多因素logistic回归分析患者合并症对移植成功可能性和并发症的影响.
    结果:在200例患者中进行了125例全厚度和93例分厚度移植,包括68个缺损(31.2%)与暴露的颅骨。全厚度移植物需要较少的平均重建(P=0.002)。92.8%的全层移植物具有完全的移植物整合,而78.5%的分层移植物具有完全的移植物整合(P=0.002)。这种差异在暴露的颅骨缺损中更为明显(87.2%vs.47.6%,P≤0.001)。尽管轻微清创率较高,全层移植物的术后骨暴露和伤口破裂少于完整的围膜和暴露的颅骨缺损。术前放射,免疫抑制,移植物大小增加是移植物结局的重要预测因素。
    结论:皮肤移植,尤其是全厚度,提供一个多才多艺的,可靠,以及在适当的患者中重建中等至较大头皮缺陷的简单方法。即使在裸露的颅骨缺损上,当准备好血管化受体床时,全层移植物可以成功。骨外露的缺损,较大的移植物尺寸,术前放疗,和免疫抑制可能导致减少移植和增加的并发症。

    OBJECTIVE: Compare full-thickness skin grafts versus split-thickness skin grafts in scalp reconstruction.
    METHODS: Retrospective chart review of patients who underwent scalp reconstruction with skin grafts performed at a single institution from 2011 to 2016.
    METHODS: χ2 or Fisher exact tests were used to compare graft integration and complication rates. The effects of graft type, defect type, graft size, and patient comorbidities on the likelihood of graft success and complications were analyzed using multivariate logistic regression.
    RESULTS: A hundred and twenty-five full-thickness and 93 split-thickness grafts were performed in 200 patients, including 68 defects (31.2%) with exposed calvarium. Full-thickness grafts required fewer average reconstructions (P = 0.002). A 92.8% of full-thickness grafts had complete graft integration compared with 78.5% of split-thickness grafts (P = 0.002). This difference was more evident in defects with exposed calvarium (87.2% vs. 47.6%, P ≤ 0.001). Despite higher rates of minor debridement, full-thickness grafts had less postoperative bone exposure and wound breakdown than split-thickness grafts on intact pericranium and exposed calvarium defects. Preoperative radiation, immunosuppression, and increased graft sizes were significant predictors of graft outcomes.
    CONCLUSIONS: Skin grafts, especially full-thickness, provide a versatile, reliable, and simple approach for reconstructing medium to large scalp defects in the appropriate patient. Even on defects with bare calvarium, full-thickness grafts can succeed when a vascularized recipient bed is prepared. Defects with exposed bone, larger graft sizes, preoperative radiation, and immunosuppression may result in decreased graft take and increased complications.
    METHODS: 3b.

    皮肤癌治疗是皮肤病学的核心方面,依赖于准确的诊断和及时的干预。远程皮肤科已成为皮肤癌护理各个阶段的宝贵资产,包括分诊,诊断,管理,和外科咨询。随着传统皮肤镜和存储转发技术的整合,远程皮肤科促进了与咨询皮肤科医生迅速共享可疑皮肤病变的高分辨率图像。实时视频会议和存储转发格式在弥合地理上孤立的患者和皮肤病学提供者之间的护理访问差距方面发挥了关键作用。值得注意的是,远程皮肤科的诊断准确率通常与传统的面对面咨询相当,强调了其强大的临床效用。人工智能和反射共聚焦显微镜等技术进步继续提高图像质量,并具有提高虚拟皮肤病护理诊断准确性的潜力。虽然远程皮肤科作为一个有价值的临床工具为所有患者人群,包括儿科患者,它不打算完全取代亲自手术,如Mohs手术和其他必要的干预措施。然而,它在促进皮肤恶性肿瘤评估方面的作用正在皮肤科社区中获得认可,并由于其实用性和及时获得专门治疗的能力而获得了患者的高批准率。
    Skin cancer treatment is a core aspect of dermatology that relies on accurate diagnosis and timely interventions. Teledermatology has emerged as a valuable asset across various stages of skin cancer care including triage, diagnosis, management, and surgical consultation. With the integration of traditional dermoscopy and store-and-forward technology, teledermatology facilitates the swift sharing of high-resolution images of suspicious skin lesions with consulting dermatologists all-over. Both live video conference and store-and-forward formats have played a pivotal role in bridging the care access gap between geographically isolated patients and dermatology providers. Notably, teledermatology demonstrates diagnostic accuracy rates that are often comparable to those achieved through traditional face-to-face consultations, underscoring its robust clinical utility. Technological advancements like artificial intelligence and reflectance confocal microscopy continue to enhance image quality and hold potential for increasing the diagnostic accuracy of virtual dermatologic care. While teledermatology serves as a valuable clinical tool for all patient populations including pediatric patients, it is not intended to fully replace in-person procedures like Mohs surgery and other necessary interventions. Nevertheless, its role in facilitating the evaluation of skin malignancies is gaining recognition within the dermatologic community and fostering high approval rates from patients due to its practicality and ability to provide timely access to specialized care.

    超级巨大基底细胞癌(SGBCC),定义为直径大于20厘米,是一种罕见的肿瘤实体,稀缺的文学。作者对SGBCC的特征进行了综述,特别是关于年龄,性偏爱,危险因素,地理位置,身体部位,转移,和治疗。1972年至2023年进行了系统的文献检索。所有摘要,研究,并对引文进行了审查。最初的结果显示了47.281个文章,并被过滤下来为人类,皮肤,英语语言,SGBCC。作者确定了20例病例报告供我们分析。样本量太小,无法进行广泛的统计分析。大多数病例在北美和欧洲报告。男性人数几乎超过女性2:1。平均年龄为61岁。20例中有16例位于躯干。在20年中的13年中,病变存在超过10年,20例中有7例报告转移。一些报告记录了低社会经济地位和不良的心理健康。关于治疗,11名患者接受了手术,6例患者使用放射治疗,4例患者使用免疫治疗(Vismodegib).尽管已知基底细胞癌(BCC)具有良好的预后,SGBCC具有高度侵略性,具有转移能力。我们的评论显示SGBCC通常在男性的第六个十年中被诊断出来,存在超过10年的持续时间,风险因素包括低社会经济地位和不良的心理健康,常见于躯干,有转移倾向。作者认为,自我忽视是大尺寸的可能病因。治疗选择可能是多模式的手术组合,放射治疗或免疫疗法(Vismodegib)。
    Super giant basal cell carcinoma (SGBCC), defined as greater than 20 cm in diameter, is a rare oncological entity, with scarce literature. The authors conducted a review to characterize SGBCC, specifically with regards to age, sex predilection, risk factors, geographical location, body site, metastasis, and treatment. A systematic literature search was conducted from 1972 to 2023. All abstracts, studies, and citations were reviewed. The initial result showed 47 281 articles and were filtered down for human, skin, English language, and SGBCC. The authors identified 20 case reports for our analysis. The sample size was too small to conduct extensive statistical analysis. Majority of the cases were reported in North America and Europe. Males outnumbered almost females 2:1. The mean age was 61 years. The lesion was located on trunk in 16 out of 20 cases. In 13 out of 20 years, the lesion had been present for more than 10 years and 7 out of 20 cases reported metastasis. Several reports documented low socioeconomic status and poor mental health. Regarding treatment, 11 patients underwent surgery, radiation was utilized in 6 patients and immunotherapy (Vismodegib) in 4 patients. Although basal cell carcinoma (BCC) is known to have a favorable prognosis, SGBCC is highly aggressive with ability to metastasize. Our review reveals SGBCC is commonly diagnosed in males in their sixth decade, present for more than 10 years duration, risk factors include low socioeconomic status and poor mental health, commonly found on the trunk with a predilection for metastasis. The authors believe self-neglect is the likely etiology of the large size. Treatment options may be multimodal with a combination of surgery, radiation therapy or immunotherapy (Vismodegib).

    角化棘皮瘤(KA)是一种常见的,低档,快速增长的皮肤鳞状细胞癌,表现为扩大的圆形结节,可能自发渐开线,但很少转移。免疫抑制,紫外光,病毒感染,外科手术,创伤与它们的发展有关。总的来说,文献中很少描述纹身诱导的鳞状细胞肿瘤。假设致癌是由纹身程序或异物对色素的反应引起的创伤引起的。然而,发病机制尚未明确。虽然最常见的是红色墨水,到目前为止,很少有在黑色内形成KA的病例,蓝色,或报告了多色墨水纹身。在这里,我们描述了在装饰性墨水纹身中的蓝色和黑色颜料区域内出现KA的情况。
    Keratoacanthoma (KA) is a common, low-grade, rapidly growing cutaneous squamous cell carcinoma that presents as an enlarging crateriform nodule, which may spontaneously involute but rarely metastasizes. Immunosuppression, ultraviolet light, viral infection, surgical procedures, and trauma are associated with their development. Overall, tattoo-induced squamous cell neoplasms are infrequently described in the literature. Carcinogenesis is hypothesized to result from trauma caused by the tattooing procedure or a foreign body reaction to the pigment. However, the pathogenesis has not been clearly defined. While most commonly associated with red ink, to date, very few cases of KA forming within black, blue, or multicolored ink tattoos are reported. Herein, we describe a case of KA arising within areas of blue and black pigment in a decorative ink tattoo.

    皮肤血管肉瘤是最常见于头颈部的侵袭性肿瘤。在这个案例报告中,我们描述了继发于侵袭性和快速扩张伤口的败血症的表现,位于身体上的防晒区域,同时患有多种合并症的患者。治疗是针对致病生物定制的,以及确定病理军团的组织学形态。组织病理学和免疫组织化学用于确认皮肤血管肉瘤的诊断。概述了以患者为中心的姑息化疗决策。
    Cutaneous angiosarcoma is an aggressive tumor most commonly presenting on the head and neck. In this case report, we describe the presentation of sepsis secondary to an aggressive and rapidly expanding wound, located in a sun-protected area on the body, in a patient with multiple concurrent comorbidities. Treatment was tailored toward targeting the causative organisms, as well as identifying the histologic morphology of the pathologic legion. Histopathology and immunohistochemistry were used to confirm the diagnosis of cutaneous angiosarcoma, and the patient-centered decision surrounding palliative chemotherapy is outlined.

    该病例描述了一种罕见恶性肿瘤的独特表现:巨大黑色素瘤。由于美国医疗保健的可及性,在没有临床干预的情况下,黑色素瘤生长到巨大的尺寸是不寻常的。事实上,深入的文献综述仅引发了少数类似病例。巨大恶性黑色素瘤通常由直径不小于10厘米的截止尺寸定义。它们通常存在远处转移并且是高度侵入性的。由于有限但高度可变的演示文稿,没有标准化的方法来治疗这类黑色素瘤。我们提出了一个具有独特特征的病例,该病例先前未在类似病例中记录过,最终采用新颖的方法进行治疗。
    This case describes a unique presentation of a rare malignancy: giant melanoma. Due to the accessibility of healthcare in the United States, it is unusual for melanomas to grow to massive sizes without clinical intervention. In fact, an in-depth literature review elicited only a handful of similar cases. Giant malignant melanomas are typically defined by a cutoff size of no less than 10 cm in diameter. They often present with distant metastases and are highly invasive. Due to limited yet highly variable presentations, there is no standardized approach to treating this class of melanomas. We present a case with unique features not previously documented in similar cases that was ultimately treated with a novel approach.

    非典型纤维黄瘤(AFX)是一种罕见的梭形细胞增殖,由大量阳光照射引起。AFX通常表现为红色丘疹,常见于老年患者的头颈部。由于免疫组织学没有特异性,各种染色将AFX与其他皮肤癌区分开。染色剂包括分化簇68(CD68),分化簇163(CD163),波形蛋白,细胞角蛋白上皮(CKAE),还有黑色素.虽然局部复发很常见,AFX很少转移。因此,治疗方案是完整的手术切除或以显微照片为导向的直方图手术。
    Atypical fibroxanthoma (AFX) is a rare spindle cell proliferation arising from significant sun exposure. AFX often appears as a red papule, typically found in the head and neck region of elderly patients. Since there is no specificity in immunohistology, various stains differentiate AFX from other skin cancers. The stains include cluster of differentiation 68 (CD68), cluster of differentiation 163 (CD163), vimentin, cytokeratin epithelial (CKAE), and melanin. While local recurrence is common, AFX rarely metastasizes. Thus, the treatment options are complete surgical excision or micrographically oriented histographic surgery.

    背景:非可移植或复合缺损重建对重建外科医生来说是一个重大挑战,许多伤口需要局部皮瓣或游离的微血管组织转移方法。最近出现的合成皮肤替代品,例如可生物降解的时间化基质(BTM),彻底改变了复杂缺陷的管理,包括由烧伤引起的缺陷。创伤和感染,具有低发病率和低复杂性的手术。然而,在澳大利亚,支持其在癌症重建中使用的数据有限。
    方法:我们对2021年2月至2023年2月在我们机构接受BTM癌症切除和重建的患者进行了一项前瞻性队列研究。报告的结果包括矩阵整合,感染,回到剧院。
    结果:在此期间,12例患者在癌症切除后接受了原发性或继发性缺损的重建。八名患者是男性,四女,手术时平均年龄为70岁.切除的病理包括头颈部鳞状细胞癌(SCC)和黑色素瘤,下肢肉瘤切除术,头皮放射性骨坏死(ORN)。原发性肿瘤的T分期范围为T2至T4,以及黑色素瘤的一次转运转移。4例患者接受放疗,其中2人接受术后放疗(PORT),2人接受新辅助放疗,另外3例患者因复发或ORN而对之前照射过的伤口床进行了干预.整体矩阵集成为83%(10/12),在放疗后观察到50%的整合率(2/4),要求回到剧院进行替代的重建方法。
    结论:我们报告了我们在癌症重建中使用合成真皮基质(BTM)的经验,澳大利亚文献中这一类型的最大群体。BTM代表了癌症重建外科医生令人兴奋的重建工具,成功率高,发病率低。
    BACKGROUND: Non-graftable or composite defect reconstruction represents a major challenge to the reconstructive surgeon, with many wounds requiring local flap or free microvascular tissue transfer approaches. The recent advent of synthetic skin substitutes such as Biodegradable Temporizing Matrix (BTM) have revolutionized the management of complex defects including those caused by burns, trauma and infection, with low-morbidity and low-complexity surgery. However, limited data exist supporting their use in cancer reconstruction in Australia.
    METHODS: We performed a prospective cohort study of patients undergoing cancer resection and reconstruction with BTM between February 2021 and February 2023 in our institution. Reported outcomes included matrix integration, infection, and return to theatre.
    RESULTS: Twelve patients underwent reconstruction of primary or secondary defects following cancer resection during this period. Eight patients were male, four female, mean age at surgery was 70 years. Pathology resected included squamous cell carcinoma (SCC) and melanoma of the head and neck, sarcoma resection of the lower limb, and osteoradionecrosis (ORN) of the scalp. T-stage of primary tumours ranged from T2 to T4 and one in-transit metastasis of melanoma. Four patients were treated with radiotherapy, two of whom received postoperative radiotherapy (PORT) and two who received neoadjuvant radiotherapy, three additional patients had an intervention to a previously irradiated wound bed for recurrence or ORN. Overall matrix integration was 83% (10/12), with a 50% integration rate (2/4) observed in the post-radiotherapy group, requiring return to theatre for alternative reconstructive approaches.
    CONCLUSIONS: We report our experience with a synthetic dermal matrix (BTM) in cancer reconstruction, the largest cohort of this type in the Australian literature. BTM represents an exciting reconstructive tool for the cancer reconstructive surgeon, with a high rate of success and low morbidity.

    Leser-Trélat征(LTS)的特征是与恶性肿瘤相关的多发性脂溢性角化病(SKs)的爆发表现。该病例突出了黑色素瘤继发的LTS的可变表现。据我们所知,这种LTS模式是这种体征表现为黑色素瘤继发的微妙模式的第一种情况。这与LTS-黑色素瘤文献中记录的5例病例相反,表现出独特的爆发模式。一名64岁的白人女性参加了健康检查。没有个人皮肤癌病史。患者表现出不规则的SKs开始增殖,她右侧中背部亚厘米黄斑痣。6mm穿刺活检对原位黑色素瘤有重要意义,出现在温和的复合性发育不良痣中,局部邻接一个周边组织边缘。完成了最小5mm边缘的再切除,标本对残留的原位黑色素瘤呈阴性。由于在黑色素瘤部位很少出现这种微妙的图案,这个演示增加了围绕这个诊断的知识。该案例强调了对与疾病相关的皮肤表现保持警惕的重要性,并强调了观察和识别细微体检结果的重要性。
    Leser-Trélat sign (LTS) is characterized as an eruptive display of multiple seborrheic keratoses (SKs) in association with malignancy. This case highlights the variable presentation of LTS secondary to melanoma. To our knowledge, this LTS pattern is the first case where the sign manifests as a subtle pattern secondary to melanoma. This stands in contrast to the five documented cases in the literature of LTS-melanoma, which exhibited distinctive and eruptive patterns. A 64-year-old Caucasian female presented for a wellness examination. No personal history of skin cancer was noted. Patient displayed an onset proliferation of SKs with an irregular, sub-centimeter macular nevus over her right lateral mid back. A 6mm punch biopsy was significant for melanoma in situ, arising within a lentiginous compound dysplastic nevus, focally abutting one peripheral tissue edge. A re-excision with a minimum of 5mm margins was completed and the specimen was negative for residual in situ melanoma. Because of the rare occurrence of this delicate pattern at the site of the melanoma, this presentation adds to the knowledge surrounding this diagnosis. This case emphasizes the importance of maintaining vigilance regarding skin manifestations associated with disease and highlights the critical importance of observation and identification of subtle physical exam findings.
