Small bowel perforation due to metastatic lung squamous cell carcinoma

Squamous cell cancer of the lung occurs with early dissemination but clinically significant metastases localized to the small bowel are rare. Small bowel metastasis is a fatal complication usually seen in advanced stages of the disease. In the present study, we report a case of a 65-year-old patient who was admitted to the emergency department with acute abdominal pain and during evaluation was found to have squamous cell carcinoma metastasis to small bowel leading to perforation. We also discuss the current management possibilities in the guidance of current literature.     

鳞状细胞癌抗原检测在预测早期宫颈鳞癌淋巴结转移中的意义

目的：探讨鳞状上皮细胞癌抗原（SCCAg）检测在预测早期宫颈鳞癌淋巴结转移中的作用。方法：对78例Ⅰ期和Ⅱa期早期宫颈鳞癌患者行手术治疗,确定淋巴结转移情况。手术当天晨取血样,快速荧光酶标法测定SCCAg。结果：早期宫颈鳞癌有淋巴结转移者SCCAg测定值高于未发生淋巴结转移者（t=7.890,P=0.000）。多因素分析调整后SCCAg水平与宫颈鳞癌淋巴结转移的OR值为1.669（Wald=9.124,P=0.000）,95%CI为1.112～2.226。SCCAg对早期宫颈鳞癌淋巴结转移预测的ROC的AUC为0.713（P=0.001）,95%CI为0.606～0.820。当截断值为3.5ng/ml时,特异度为0.714、灵敏度为0.651、Youden指数为0.365,其预测价值最佳。结论：SCCAg对早期宫颈鳞癌淋巴结转移有较好的预测价值,当截断值为3.5ng/ml时,预测价值最佳。

Dysphagia as a primary manifestation of thyrotoxicosis: a case report

This report deals with a middle aged man in whom the presenting symptom of the disorder was dysphagia. The clinical approach to the final diagnosis of thyrotoxic myopathy causing dysphagia is outlined and the pathophysiology of dysphagia then discussed. The need to include thyrotoxicosis in the differential diagnosis of an otherwise unexplained case of dysphagia is stressed.     

Subungual squamous cell carcinoma masquerading as a melanotic macule

Subungual squamous cell carcinoma is a rare condition. Diagnosis is often delayed because it presents with minimal nail changes and mimics a number of benign nail conditions. We report a 43-year-old Chinese man who presented with a three-year history of an indolent melanotic macule of the fingernail. Histology from a punch biopsy revealed a well-differentiated squamous cell carcinoma. Wide local excision with full thickness skin grafting was performed. Physicians should have a high index of clinical suspicion as early nail biopsy and prompt tumour clearance can preserve joint function.     

Bovine ocular squamous cell carcinoma: an epidemiological perspective

Epidemiological studies on bovine ocular carcinoma were reviewed. Reports on the frequency and the distribution of the disease indicate that it is still a very prevalent and economically important disease. It is recognized throughout North America, but is more frequent in lower latitudes under range conditions. Etiological factors including ultraviolet light, circumocular apigmentation and viruses, as well as the pathogenesis, are considered in light of current knowledge on carcinogenesis of this tumor. It is likely that the induction of bovine ocular carcinoma is multifactorial and the precise roles played by each of the various factors are not yet understood.     

早期食管鳞癌合并上皮角化的回顾性研究

目的 探讨早期食管鳞癌合并上皮角化患者的临床、内镜及病理特征.方法 收集行内镜黏膜下剥离术、术后病理证实为早期食管鳞癌患者,依据其内镜有无白斑表现,分为2组,采集其临床、内镜和病理资料进行总结分析.结果 263例食管鳞癌患者中,有90例合并上皮角化.在所有角化患者中,60岁以上患者发生角化的比例远高于60岁以下患者,且与非角化患者相比,发生于60岁以上患者比例更高(81.11％vs 66.47％,P=0.013),且更易发生于女性(40.00％vs 21.97％,P=0.002).此外,角化患者中有吸烟史者较非角化患者多(35.56％vs 23.70％,P=0.042).在角化患者中,白斑较多较之于散在病变者,病变较大(80.77％vs 48.44％,P=0.005),病变浸润较深(M1:3.85％vs 20.31％;M2:57.69％vs 71.88％;M3:26.92％vs 4.69％;SM:11.54％vs 3.13％;P<0.001).结论 对于老年患者、女性、既往有吸烟史者,早期食管鳞癌更容易合并食管角化,临床医师应对角化白斑未完全覆盖的发红区域进行重点观察,对于角化程度较严重的病变,应警惕其浸润深度可能相对较深.     

Diabetic ketoalkalosis due to ectopic ACTH production from an oat cell carcinoma

A diabetic patient is described who presented with the bizarre biochemical association of hyperglycaemia, ketosis and severe alkalosis. Investigation revealed hypercortisolaemia due to ectopic adrenocorticotrophic hormone secretion from an oat cell carcinoma of the bronchus and post-mortem studies demonstrated clinically unsuspected resolving pancreatitis. a possible mechanism for the metabolic upset is discussed.     

鳞癌抗原在子宫颈鳞癌中的应用价值

目的:探讨鳞癌抗原(SCCAg)在子宫颈鳞癌中的临床应用价值.方法:微粒子酶免法检测124例子宫颈鳞癌患者治疗前血清SCCAg值,对照组180例为妇科良性疾病患者.早期患者(Ⅰ～Ⅱa期)术后一周重复检测SCCAg值,部分根治手术患者随诊中监测.结果:SCCAg在子宫颈鳞癌中的敏感性为73.4%,特异性为96.1%.SCCAg阳性率随临床分期进展而增高,差异有显著性(P＜0.005),早期患者(Ⅰ期和Ⅱa期)术前 SCCAg值异常者术后均下降至正常水平,差异均有显著性(P＜0.001).部分术后患者在3年随访期内血清SCCAg值在正常水平.结论:SCCAg是子宫颈鳞癌较特异的肿瘤标志物,可以作为子宫颈癌辅助诊断指标,评估子宫颈癌手术疗效,在早期浸润癌中的临床意义值得进一步研究.

Cheilitis glandularis progressing to squamous cell carcinoma in an hiv-infected patient: case report

Cheilitis glandularis (CG), is a rare inflammatory minor salivary gland disease affecting the lower lip. The hallmarks of which include progressive enlargement and eversion of the lower labial mucosa resulting in the obliteration of the mucosal-vermillion interface. A case is presented of a 47-year-old HIV-infected woman who initially manifested clinical features of CG with a typical histopathology picture of a non-specific sialadenitis while a second biopsy performed six months later revealed well differentiated squamous cell carcinoma (SCC). She is symptom free one year following excision and radiotherapy treatment.
