胃原发性淋巴瘤临床诊断殊为困难,甚至在手术探查时也很难将癌与淋巴瘤区分开.即使是胃镜下咬检组织或大体组织切片亦会发生误诊.胃原发恶性淋巴瘤少见,多数作者统计占胃恶性肿瘤的2~5%,国人统计有更低者,仅占胃恶性肿瘤的0.6%.我院自1974年以来经治胃原发性恶性淋巴瘤10例,均有病理证实.除1例由纤维胃镜确诊外,其余9例术前均误诊为癌和溃疡恶变. 相似文献

肠病相关T细胞淋巴瘤(EATL)是一种少见的来源于上皮间T淋巴细胞的结外淋巴组织发生的恶性淋巴瘤。临床和病理诊断均有一定困难,极易和肠道其他恶性肿瘤,尤其是未分化癌相混淆。为了提高对本病的诊断水平,减少误诊。本文收集肠病相关T细胞恶性淋巴瘤38例,进行分析如下。 相似文献

淋巴瘤是原发于淋巴结或淋巴结外组织或器官的恶性肿瘤。根据患者的临床和病理特点不同,可分为霍奇金淋巴瘤(HL)和非霍奇金淋巴瘤(NHL)两大类。恶性淋巴瘤治疗的关键是早期诊断、准确分期及疗效评估。近十年来大量临床研究 相似文献

以结外侵犯为首发症状的恶性淋巴瘤66例临床分析 总被引:1,自引:0,他引:1
恶性淋巴瘤是造血系统的恶性肿瘤。淋巴组织遍布全身,所以淋巴瘤可发生在身体的任何部位。淋巴瘤通常以实体瘤形式生长于淋巴组织丰富的组织器官中,由于病变部位和范围不相同,临床表现很不一致,常以进行性、无痛性淋巴结肿大为首发症状。但在临床工作中,有相当数量的患者以结外侵犯为首发症状,而就诊于消化内科、耳鼻咽喉科、口腔科、骨科、皮肤科、胸科、乳腺科等,常被误诊为各专科的常见病,影响到恶性淋巴瘤的早期诊断和治疗。本文对本院2004年6月-2007年8月66例以结外侵犯为首发症状的恶性淋巴瘤患者的临床资料进行分析。 相似文献

弥漫大B细胞淋巴瘤是最常见的非霍奇金淋巴瘤,p63在弥漫大B细胞淋巴瘤中可表达,因此在临床上易被误诊为p63阳性的上皮源性恶性肿瘤,尤其在淋巴结发生转移时。本研究报道1例以呼吸道症状为首发症状的弥漫大B细胞淋巴瘤患者,临床高度怀疑肺恶性肿瘤并淋巴结转移。行右腋窝淋巴结穿刺活检病理诊断,结果显示p63阳性,提示为鳞状细胞癌,而完善免疫组织化学检查后,最终诊断为弥漫大B细胞淋巴瘤。因此,认识p63阳性的弥漫大B细胞淋巴瘤很有必要,可减小临床误诊的可能性。 相似文献

淋巴瘤是由淋巴系统发生的一组恶性肿瘤,且高达40%的淋巴瘤出现在结外位置[1]。结外淋巴瘤的病理类型以非霍奇金淋巴瘤为主,其中弥漫性大B细胞淋巴瘤和黏膜相关淋巴组织淋巴瘤占结外淋巴瘤的[2]诊断结外淋巴瘤的最严格定 相似文献

淋巴瘤是起源于淋巴结和淋巴组织的免疫系统恶性肿瘤,其发生大多与免疫应答过程中淋巴细胞增殖分化产生的某种免疫细胞恶变有关,以无痛性进行性的淋巴结肿大和局部肿块为其特征性的临床表现,并可有相应器官压迫症状[1].无论原发还是继发,肌肉淋巴瘤极为罕见[2.3].由于发病率低,表现多种多样,故误诊误治率极高.现将我科收治的肌肉淋巴瘤误诊为糖尿病肌病1例分析如下. 相似文献

OBJECTIVE: Although nausea and vomiting of pregnancy is the most common medical condition during pregnancy, there are many unanswered questions regarding its cause, epidemiologic features and optimal management. The objectives of this study were to ascertain the prevalence of nausea and vomiting in a sample of Canadian women, to characterize the distribution of their severity and to investigate the role of vitamin B6 deficiency in their etiology. DESIGN: Prospective study. SETTING: Antenatal counselling service for pregnant women. PATIENTS: Three cohorts of women: a prospective, population-based cohort of 193 women, to estimate the rate and severity of nausea and vomiting (cohort A); a cohort of 555 women who sought advice for nausea with or without vomiting, to study the correlation between the maximal daily number of episodes of vomiting and maximal weight loss (cohort B); and a prospective cohort of 301 women who reported vomiting, to correlate vitamin supplementation with vomiting (cohort C). INTERVENTIONS: All 3 cohorts were interviewed during the counselling session, and cohort B was followed up prospectively. OUTCOME MEASURES: Frequency of nausea and vomiting, weight loss, maximal number of daily episodes of vomiting, rate of multivitamin supplementation. RESULTS: Overall, 67% of the women in cohort A reported experiencing nausea or vomiting, or both; 22% reported vomiting, and 9% experienced weight loss. In cohort B there was a significant correlation between the maximal number of daily episodes of vomiting and maximal weight loss, although there was wide variation (r2 = 0.25, p < 0.001). There was a highly significant correlation between the number of daily vomiting episodes and mean weight loss (r2 = 0.99). In cohort C, vomiting was significantly associated with lack of supplementation with multivitamins before 6 weeks' gestation (p = 0.002). CONCLUSIONS: The relation between number of daily vomiting episodes and mean weight loss may serve as a clinical tool to assess the severity of nausea and vomiting in pregnancy and the success of anti-emetics and rehydration regimens. Further study is needed to elucidate the biologic basis of the observed association between vomiting and lack of multivitamin supplementation in early pregnancy. 相似文献

心血管疾病是我国的多发病和人群的主要死亡原因之一,而高血压已成为中老年人的常见病,是冠心病、脑卒中最主要的危险因素,已成为世界性公共卫生问题。随着我国经济的发展及人们生活水平的日益提高,我国在1958年、1979年、1991年分别进行了全国性的高血压普查,结果表明,我国高血压患病率在持续上升,且上升速度逐年加快。由于文化程度、生活习惯以及信息来源不足的差异也是导致城居民高血压患病率持续上升的重要原因,因此指导城乡居民进行合理的饮食,对预防高血压的发生、发展有着重要的意义。 相似文献

A form of the Semantic Differential, containing 9 concepts related to hypnosis and research, was administered to 96 hypnotically inexperienced male Ss. The Ss were later asked to volunteer for a hypnotic experiment, and the hypnotic susceptibility of all volunteers (N = 51) was then determined. Semantic Differential responses of volunteers and nonvolunteers and of highly susceptible and unhyp-notizable Ss were compared. Differences between groups, in both comparisons, were generally not statistically significant, a finding which suggests that there is no simple relationship between paper-and-pencil measures of attitudes and volunteering for hypnotic experiments or hypnotizability. 相似文献

目的 为了解麻疹和风疹的临床症状特征,并评价不同麻疹疑似病例定义的监测效果。 方法 2010年在北京市昌平区开展发热出疹性病例的流行病学调查,收集病例的一般情况、临床症状和体征、免疫史等信息。 结果 麻疹和风疹在发热程度、皮疹持续时间、发热至出疹时间间隔以及卡他症状、结膜炎、淋巴结肿大和关节疼痛等临床症状和体征有明显差异。北京市和卫生部麻疹疑似病例诊断标准的敏感度和特异度分别为94%、50%和45%、94%。如以"发热≥38℃,发热后第3天或以后出疹,并伴有卡他症状或结膜炎之一者"作为麻疹疑似病例诊断标准,敏感度和特异度分别为81%和92%。 结论 北京市麻疹发病率较低,北京市麻疹疑似病例诊断标准的敏感度较高,对于消除麻疹,及时发现病例有效。在消除麻疹进程中,要视不同发病率选择适宜的监测病例定义,以提高监测效力。 相似文献
