Squamous cell carcinoma of the breast following silicone injection of the breasts

During the 1960s, injecting liquid silicone into the breasts for augmentation purposes was a common practice. Many women suffered complications, usually developing silicone mastopathy, but there have been reports of carcinoma as well. A case of squamous cell carcinoma of the breast is reported in a patient who had previously undergone injection of silicone into the breasts. Upon review of the literature, this is only the second reported case of squamous cell carcinoma of the breast following silicone injection. Squamous cell carcinoma of the breast is a very rare tumor comprising 0.04 to 0.075 percent of all breast malignancies. The tumor appears to develop from metaplasia of benign epithelial cells within the breast. Many theories are presented for the development of this metaplastic process. The clinical presentation, evaluation, and treatment of squamous cell carcinoma of the breast is quite similar to that of infiltrating ductal carcinoma of the breast of comparable stage and size.

食管基底细胞样鳞状细胞癌临床病理分析

目的探讨食管基底细胞样鳞癌(BSC)的临床病理特点.方法回顾分析10年间食管癌手术病理档案,对符合基底细胞样鳞癌的病例行免疫组化标记.结果2*!960例食管癌中10例为食管基底细胞样鳞癌,占0.3%.其中8例曾误诊为低分化鳞癌、腺鳞癌、腺样囊性癌和小细胞癌.肿瘤主要由核大浆少的基底细胞样癌组织与多少不等的鳞癌或(和)原位鳞癌构成,两者间无移行.1例部分细胞免疫组化癌胚抗原阳性,2例局部癌组织突出素、嗜铬素阳性,1例灶性角蛋白17、角蛋白8阳性;无一例表达S100和肌动蛋白.结论食管基底细胞样鳞癌主要由基底样细胞组成,并具有鳞癌的变异型,具有高侵袭性又易在病理上误诊,因而需要对其临床和病理特征进行透彻研究和进一步提高认识.     

Survivin在宫颈鳞癌中的表达及其意义

目的研究Survivin在宫颈鳞癌组织中的表达及其意义。方法采用免疫组化S-P法对53例不同分化程度的鳞癌组织及10例慢性宫颈炎组织进行Survivin检测。结果10例慢性宫颈炎组织中未发现Survivin阳性表达，53例宫颈鳞癌中Survivin阳性表达率为54．7％（29／53），阳性表达的Survivin主要定位于肿瘤组织的细胞浆，偶见于细胞核。结论宫颈鳞癌组Survivin阳性表达显著高于慢性宫颈炎组，并与富颈鳞癌的分化程度有关，提示Survivin参与了宫颈癌的发生和发展过程。     

Squamous cell lung cancer presenting with pulmonary lymphangitic carcinomatosis

Pulmonary lymphangitic carcinomatosis (PLC) refers to the infiltration of lung lymphatic channels with metastatic carcinoma and is associated with a dismal prognosis. PLC accompanies circa 7% of all pulmonary metastases and is most commonly caused by various metastatic adenocarcinomas. Only two cases of PLC due to squamous cell lung carcinoma have been reported to date in the English literature. We report herein a unique case of squamous cell lung carcinoma with lymphangitic spread, displaying bilateral and diffuse bronchial tree involvement that might have been a result of invasion from the pulmonary lymphatics into the bronchial lumen.     

原发性膀胱鳞状细胞癌的诊治体会(附4例报告)

我院自１９８２年１月至１９９４年１２月收治膀胱鳞癌４例，占同期膀胱肿瘤的３．３％。均在现有膀胱刺激症和血尿，３例伴膀胱结石，２例有膀胱切开取石史。文章就膀胱鳞癌的组织发生、病理过程及诊断和治疗进行了讨论。     

Minute lung carcinoma associated with focal honeycombed lesion

We report a case of minute lung carcinoma that developed in a focal honeycombed lesion in the right lung. A 70-year-old man presented hemosputum, and a cytological examination result was at class IV. A right lower lobectomy of the lung was performed. Microscopically, the thickened alveolar wall revealed tumor cells indicating a minute carcinoma, and showed squamous hyperplasia, metaplasia, and dysplasia, with the carcinoma in the distal airway epithelium. This peripheral lung carcinoma in a focal honeycombed lesion demonstrated the various stages of multistep carcinogenesis, which is recognized in hilar type squamous cell carcinoma. To date, the association between a honeycombed lesion and lung cancer has been poorly described. Here we have presented clear evidence of the association of this carcinoma with the honeycombed lesion.

目的 探讨p73、p63和p53蛋白在喉鳞状细胞癌发生、发展中的作用与意义,为喉鳞癌的临床诊断及治疗提供新的思路,并为基因治疗的探索提供理论依据.方法 采用免疫组织化学(S-P法)检测p73、p63、p53蛋白在50例喉鳞状细胞癌、10例癌旁组织及10例正常喉黏膜中的表达,分析3种基因蛋白与喉鳞癌的临床病理特征之间的关系.结果 (1)p73表达与局部淋巴结转移成正相关(P<0.01).p73阳性表达的患者生存率相对较低(P<0.05).(2)p63表达与临床分期成负相关(P<0.05),与其他临床特征及生存率无关(P>0.05).(3)p53表达与各临床特征均无关,p53阳性表达的患者生存率相对较低(P<0.05).结论 (1)喉鳞状细胞癌中的p73过表达可能与局部淋巴结转移有关.p73阳性表达可能是患者预后不良的指标.(2)p63过表达的肿瘤恶性度可能相对较低,p63的表达与患者预后无直接联系.(3)p53阳性表达的患者预后较差.(4)提示p53家族可能和喉鳞状细胞癌形成的早期阶段有关.

原发性甲状腺鳞状细胞癌1例并文献复习

 观察1例原发性甲状腺鳞癌患者的诊治经过,结合文献分析原发性甲状腺鳞状细胞癌的临床特征和生存相关因素。早期诊断和早期治疗对于原发性甲状腺鳞癌患者的生存质量和生存时间具有决定性的作用。甲状腺良性肿瘤长期刺激也有可能导致细胞鳞状化生和癌变,早期手术并能完整切除肿瘤是最重要的决定预后的因素,放化疗可进一步延长患者的生命。临床工作重点是早期诊断甲状腺鳞癌,甲状腺良性肿瘤的随访和处理应该更积极,治疗上首选手术,可适当辅以放化疗。     

厄洛替尼在晚期非小细胞肺癌中的临床应用分析

目的 探讨厄洛替尼在晚期非小细胞肺癌（NSCLC）患者中的应用价值.方法 选择晚期NSCLC（腺癌和鳞癌）患者,腺癌和鳞癌患者均分为未治疗组、化疗组、靶向治疗组及化疗＋靶向治疗组.靶向治疗服用厄洛替尼.通过生存分析比较各组中位无进展生存期（PFS）及中位总生存期（OS）.结果 肺腺癌及肺非腺癌各自的四组间,中位PFS、OS均存在统计学差异,靶向治疗组中位PFS、OS均较未治疗组的长.肺腺癌患者中,表皮生长因子受体（EGFR）基因突变型组和野生型组的中位OS差别有统计学意义.结论 厄洛替尼治疗的晚期NSCLC患者中位PFS及OS较未治疗者长;厄洛替尼治疗的肺腺癌患者,EGFR基因突变型者中位OS较野生型者长.     

Squamous cell carcinoma arising in a subcutaneous dermoid cyst

A case of malignant transformation to a squamous cell carcinoma in a long-standing subcutaneous dermoid cyst in a 44 year old man is presented. Malignant transformation in dermoid cysts is extremely uncommon and has never previously been recorded at this site. The need for adequate investigation and treatment of superficial midline lesions presenting in childhood is emphasized.     

Invasive cutaneous squamous cell carcinoma presenting as a nonhealing radiation wound: a case report

Cutaneous squamous cell carcinoma is the second most common form of skin cancer and accounts for 20% of cutaneous malignancies. We report the case of a patient who presented with a complaint of nonhealing wounds following radiation therapy for the treatment of noninvasive squamous cell carcinoma of both lower extremities. Initial biopsies of the wounds were benign. However, a second biopsy performed approximately 2 months later was found to be positive for invasive squamous cell carcinoma. This case uniquely exemplifies that all nonhealing wounds should be viewed with a critical eye for possible malignancy even in the presence of previous negative biopsy. This is especially true for radiation wounds that may be prone to malignant transformation or recurrence.     

Basaloid squamous cell carcinoma of nasopharynx: an extremely rare variety of tumour of nasopharynx

Nasopharyngeal carcinoma is the predominant tumour type arising in the nasopharynx with cervical lymphadenopathy present in 60-90% of all cases at the time of presentation. The most pathological varieties include squamous cell carcinoma well-differentiated keratinising, and moderately differentiated non-keratinising and an undifferentiated type. The rare variety of squamous cell carcinoma is basaloid type, according to the "WHO Classification of Tumours Pathology and Genetics: Head and Neck Tumours". In this study, we present a case of basaloid squamous cell carcinoma of nasopharynx in a 41-year female who presented with epistaxis and bilateral cervical lymphadenopathy.     

银屑病与白血病的关系--附33例报告

目的：探讨银屑病与白血病的关系。方法：对１９例银屑病合并白血病患者的临床表现、血液学、骨髓染色体和１４例初治的银屑病患者的外周血淋巴细胞染色体进行研究。结果：发现银屑病患白血病者中１３例（１３／１９）有服用乙双吗啉或乙亚胺历史,其余为未经乙双吗啉和其他治疗者。银屑病患白血病者的临床表现、治疗效果及染色体结果与原发性白血病改变相类似。５例（５／１４）未经治疗的银屑病患者外周血淋巴细胞染色体的超二倍体明显高于正常人。结论：银屑病易患白血病的病因除了与药物有关,体细胞的染色体不稳定性可能起重要作用     

基于形态学特征提取的人工神经网络在口腔鳞状细胞癌诊断中的应用

目的 基于形态学图像处理方法,应用径向基神经网络(radial basis function,RBF)寻找一种可行、便捷的方法辅助口腔鳞状细胞癌的诊断.方法 选择口腔鳞状细胞癌和口腔非癌的组织病理切片图像进行形态学方法处理,提取表述特征的向量,作为训练集训练RBF网络;另选择67帧病理图像,包含癌和非癌的病例,作为测试集观察RBF的性能.结果 在RBF网络将测试标本分类结果的分析中可以看到不同输出值分类阈值的选择对应不同的诊断敏感度和特异度.结论 训练后的RBF虽然鉴别阳性、阴性的能力不能和金标准(即病理诊断)相比,但是通过选择不同敏感度和特异度,依然能够有效辅助病理医师,提高诊断效率,发挥机器的优势.

目的观察CyclinE,P27在皮肤鳞状细胞癌发生发展中的作用。探讨CyclinE,P27在不同级别皮肤鳞状细胞癌组织中表达间的关系。提供皮肤鳞状细胞癌病因及发病机制研究的理论基础。方法用免疫组织化学技术检测35例皮肤鳞癌石蜡包埋组织和8例正常皮肤组织CyelinE,P27,的表达。结果CyclinE在皮肤鳞癌组织中表达高于皮肤正常对照组,两者差异有统计学意义（P〈0．01）,在皮肤鳞状细胞癌组织中各分级闻表达强度差异有统计学意义（P〈0．05）;P27在皮肤鳞癌组织中表达低于皮肤正常对照组,两者差异有统计学意义（P〈0．05）,在皮肤鳞状细胞癌组织中各分级间表达强度差异有统计学意义（P〈0．05）。结论CyclinE在皮肤鳞状细胞癌组织中阳性表达上调,P27在皮肤鳞状细胞癌组织中阳性表达下调,CyclinE在皮肤鳞状细胞癌组织中各分级间表达强度差异有统计学意义,分级越高表达强度也越高;P27在皮肤鳞状细胞癌组织中各分级闻表达强度差异有统计学意义,分级越高表达强度也越低。CyclinE,P27在皮肤鳞癌中表迭呈负相关。     

黑色素瘤抗原-A10蛋白在肺癌中的表达及意义

目的：观察黑色素瘤抗原(MAGE)-A10在不同类型肺癌的表达分布和临床意义。方法：应用组织芯片技术、免疫组化S-P法研究MAGE-A10在65例肺癌患者的表达情况，并分析其与病理类型、病理分级的关系。结果：MAGE-A10蛋白在小细胞肺癌、肺鳞癌和肺腺癌的阳性表达率分别为36．4％、76．5％和40．0％，在大细胞肺癌和支气管肺泡癌中未见阳性表达。MAGE-A10蛋白在小细胞肺癌与非小细胞肺癌的表达率未见差异，与肺鳞癌、肺腺癌的病理分级也无明显关系。结论：MAGE-A10分子在肺鳞癌中表达率最高，肺腺癌和小细胞肺癌次之，大细胞肺癌和支气管肺泡癌中未见表达，对鉴别诊断可能有辅助意义，并可能成为某些肺癌生物学治疗的潜在靶点。     

人乳头瘤病毒与皮肤鳞状细胞癌的相关性研究进展

人乳头瘤病毒（human papilloma virus,HPV）是小的无包膜嗜上皮性双链环状DNA病毒,人是其唯一宿主。随着HPV在皮肤鳞状细胞癌及其相关疾病中不断被发现,尤其在疣状表皮发育不良、光化性角化病中具有较高的检出率,HPV与皮肤鳞状细胞癌的相关性越来越受到重视。
