目的:探讨臀部双侧V-Y推进岛状皮瓣修复肛周Paget病术后继发肛周缺损的临床效果。方法:回顾性分析2009年1月至2021年1月期间杭州市第三人民医院皮肤科13例肛周Paget病患者在肿瘤切净后采用臀部双侧V-Y推进岛状皮瓣修复肛周缺损的临床资料，总结术后臀部恢复情况以及对肛门排便功能的影响。结果:13例肛周缺损面积4.8 cm × 5.6 cm ~ 12.2 cm × 16.4 cm，采用臀部双侧V-Y推进岛状皮瓣修复缺损，全部一期愈合。1例行临时性回肠造口术，3个月后行回肠造口回纳术后，肛门排便功能恢复；1例合并直肠癌，行乙状结肠永久性造口术分流粪便，肛门排便功能丧失。随访1 ~ 6年，13例患者臀部形态对称，12例肛门保留者排便功能正常。未合并其他恶性肿瘤的12例肛周Paget患者术后肿瘤无复发，3例患者出现肛门轻度狭窄，无肛门黏膜外翻，无伤口裂开；1例合并肛管腺癌的肛周Paget病患者在术后1年出现双侧腹股沟淋巴结、髂内淋巴结转移，半年后死亡。结论:臀部双侧V-Y推进岛状皮瓣血供可靠，推进幅度大，可修复肛周较大面积的皮肤缺损。

Introduction::Genital herpes is one of the most common sexually transmitted infections worldwide. Most genital herpes occur on the genitalia, perineum, buttocks, upper thighs, or perianal areas. However, there were reports of rare cases of genital herpes on urethral orifice.Case presentation::A 53-year-old woman presented with vagina pruritus at first, with subsequent burning sensation around urethra. Mycostatin and mycospor were administered for the treatment of the pruritus. Then levofloxacin was prescribed. Finally, the patient was given treatment with acyclovir. Different from other cases, the investigation showed herpes simplex virus type 1 DNA positive and herpes simplex virus type 2 DNA negative by PCR. The patient was therefore diagnosed with genital herpes.Discussion::Most genital herpes happen on the genitalia, perineum, buttocks, upper thighs, or perianal areas. Few cases have been reported that genital herpes occurred on urethral orifice till now.Conclusion::If there is no typical symptoms that patient present with herpes simplex virus type 1 or 2 positive, urethral orifice genital herpes should be considered.

Introduction::Tuberculosis verrucosa cutis is a rare form of cutaneous tuberculosis and occurs commonly on the lower extremeties (hand, thighs and buttock). It is often missed as other cutaneous verrucosa dieases and the pathogens of cutaneous tuberculosis is difficult to find.Case presentation::A 54 Chinese male presented with 9-year history of asymptomatic verrucous lesions on bilateral buttocks. Lesions presented a well-defined plaque, verrucous lesion and yellow pus discharge on buttocks. The skin biopsy showed pseudoepitheliomatous hyperplasia of the epidermis and dermal granulomatous inflammation composed of epithelioid histiocytes and mixed inflammatory cells. The tuberculin test and the polymerase chain reaction for Mycobacterium tuberculosis were negative, but T-spot test were positive. the treatment of antituberculosis showed favourable effect. Finally, the diagnosis of tuberculosis verrucosa cuti was made. Discussion::Tuberculosis verrucosa cutis is easily confused with other verrucous diseases, such as verrucous porokeratosis, discoid lupus erythematosus hypertrophicus lichen planus, chromoblastomycosis. Diagnostic therapy is usually recommended for most of these diagnoses.Conclusion::A diagnosis of tuberculosis verrucosa cutis should be taken correctly based on the combination of clinical manifestions, histopathological characteristics, laboratory findings and diagnostic therapy. It is vital for dermatologists to be aware of verrucous lesions since a delay in diagnosis can lead to aggravate the disease, abuse of glucocorticoids.

目的:构建裸鼠皮肤鳞状细胞癌（CSCC）移植瘤模型，探讨紫外线（UV）损伤及人乳头瘤病毒（HPV）感染诱导、促进CSCC的协同作用机制。方法:将人CSCC细胞A431分成3组，即用HPV16 E6腺病毒转染的HPV16 E6过表达组，空白腺病毒转染的空白载体组（简称空载组），未进行腺病毒转染的空白对照组。使用无血清DMEM培养基将空载组及HPV16 E6过表达组（LV-OE-HPV16 E6组）A431细胞制成单细胞悬液，分别接种于SKH-1裸鼠左侧臀部皮下作为空载组（ n = 16）和LV-OE-HPV16 E6组（ n = 16）。每3天观察并记录小鼠肿瘤生长情况，当瘤体达到150 mm 3时，视为建模成功。建模成功后，每组取8只小鼠进行UV照射，分为4组，即空载组、空载+ UV组、LV-OE-HPV16 E6组、LV-OE-HPV16 E6 + UV组，UV照射剂量为1 440 mJ/（cm 2·d），每次12 min，持续4周后处死裸鼠，测量瘤重及体积，绘制肿瘤生长曲线，免疫组化、Western印迹和qRT-PCR检测验证Wnt1、β联蛋白mRNA及蛋白在裸鼠CSCC中的表达。数据若符合正态分布，多组间比较采用方差分析，组间两两比较采用LSD- t检验；数据若不符合正态分布，采用秩和检验对数据进行统计分析。 结果:空载+ UV组瘤重为（2.90 ± 0.36）g，LV-OE-HPV16 E6组（3.19 ± 0.32）g，LV-OE-HPV16 E6 + UV组（4.41 ± 0.18）g，与空载组（2.20 ± 0.24）g比较，差异均有统计学意义（ t值分别为4.39、6.77、20.11，均 P<0.001）；空载+ UV组瘤体积为（1 033.12 ± 400.15）mm 3，LV-OE-HPV16 E6组（1 119.21 ± 447.57）mm 3，LV-OE-HPV16 E6 + UV组（1 464.29 ± 409.98）mm 3，与空载组（688.94 ± 319.31）mm 3比较差异均有统计学意义（ t值分别为1.90、2.21、4.22，均 P<0.001）。免疫组化显示，4组间Wnt1、β联蛋白表达水平差异无统计学意义（ F值分别为0.76、0.71，均 P > 0.05）；Western印迹显示，4组间Wnt1、β联蛋白水平差异有统计学意义（ F值分别为16.74、49.90，均 P<0.05），且LV-OE-HPV16 E6 + UV组Wnt1、β联蛋白水平高于空载组、空载+ UV组和LV-OE-HPV16 E6组（均 P<0.05）。mRNA水平分析显示，4组间组织中Wnt1、β联蛋白mRNA水平差异均有统计学意义（ F值分别为7.77、8.38，均 P<0.05），且LV-OE-HPV16 E6 + UV组Wnt1 mRNA水平高于空载组、空载+ UV组和LV-OE-HPV16 E6组（均 P<0.05）。 结论:UV和HPV感染在诱导、促进CSCC中具有协同作用。

Introduction::Primary systemic amyloidosis is characterized by clonal plasma cell disorder, and its signs and symptoms are various and complex, damage to the skin and mucous membrane is often more likely to attract attention.Case presentation::A 61-year-old man was hospitalized due to repeated burning sensation on his back, multiple ecchymosis, and skin vegetations. Through a series of examinations (mainly including skin histopathology, bone marrow cytology, bone marrow flow cytometry, immunofixation electrophoresis), Primary systemic amyloidosis was diagnosed, but multiple myeloma could not be diagnosed. Subsequently, he received chemotherapy. In the half-year follow-up, there was no significant change in his symptoms and signs.Discussion::In this case, in addition to the typical skin damage of primary amyloidosis, the multiple skin vegetations in the buttocks, abdomen, and arms are particularly noteworthy. According to the histopathology and Immunohistochemistry of the skin vegetation, we infer that the formation mechanism of these skin vegetation is lymphatic obstruction caused by amyloid, which leads to lymphatic dilatation, lymph leakage, and dermal edema.Conclusion::Primary systemic amyloidosis is a rare disease, which is often difficult to diagnose. We should be alert to those atypical skin features so as not to delay diagnosis.
