下消化道出血的易忽略原因——结肠血管发育异常三例报告

对于下消化道出血的病因和定位诊断,采用传统的胃肠钡剂造影、结肠镜检,以至手术探查,仍有22%病人未能明确。随着选择性肠系膜动脉造影的开展,以及嗣后的纤维结肠镜检查,证明结肠血管发育异常(Vascular dysplasias of colon)并不罕见,可占下     

浆细胞样淋巴细胞性淋巴瘤 附11例报告

原发性食管胃交界处恶性黑色素瘤1例及文献复习

目的 分析原发性食管恶性黑色素瘤的临床病理学特征。方 法对1例原发性食管胃交界处恶性黑色素瘤进行组织学观察和免疫组化标记，同时复习相关文献。结果原发性食管胃交界处恶性黑色素瘤的组织学改变类似于皮肤发生的恶性黑色素瘤。免疫表型：肿瘤细胞HMB45、S-100蛋白和vimentin阳性，cytokeratin阴性。同时必须排除皮肤、眼等处的原发病灶。结论 原发性食管胃交界处恶性黑色素瘤(无色素性)是一种罕见的肿瘤，应该与一些食管发生的肿瘤相鉴别如低分化癌、肉瘤和转移性恶性黑色素瘤等。本瘤预后极差，术后平均生存时间仅为10个月。     

Krukenberg瘤七例报告

Krukenters瘤是指卵巢内见含有粘液的印戒细胞、管状腺样结构和间质增生构成的转移癌。其原发癌多来自胃肠道,也可以来自胆囊、胰腺及乳腺等处。据统计70%来自胃癌,15%来自结肠癌,5%来自乳腺癌。近4年来我们遇到7例Krukenterg瘤,有5例原发癌在胃,1例在结肠,1例在直     

呼吸道咳出支气管类癌肿瘤组织一例报告

患者男,59岁。1985年曾患肺结核,经二年抗结核治疗痊愈。以后有间歇干咳,痰中不带血。1989年8月咳出肉样组织一块(未送检)。1990年12月晨起又咳出花生米大小肉样组织一块,并有数口鲜血,无其他不适。一周内做纤维支气管镜检查无异常发现。将咳出组织送检,大小:2cm×1cm×1cm,     

Kikuchi病一例报道及文献复习

Kikuchi病又称Kikuchi淋巴结炎、Kikuchi—Fujimoto淋巴结炎或组织细胞坏死性淋巴结炎。多见于亚洲国家，好发于年轻女性，主要表现为1个或多个颈部淋巴结肿大，可伴有发热。Kikuchi病是一种自限性疾病，对此疾病认识不足易误诊为恶性淋巴瘤。     

原发性中耳神经鞘膜瘤一例报告

患者男性,25岁,因左耳间歇性疼痛,检查发现左鼓室新生物可疑,于1981年8月22日住院。患者先有间歇性头晕,伴发饥饿感并手足抽搐病史已9年。近年来经常有左耳鸣,但未觉耳聋。1981年4月起,左耳常觉隐痛,并发作性刺痛,与此同时听力也日趋下降。全身检查无特殊发现。本科检查见左鼓膜紧张部后方透红,无搏动表现。鼓室穿刺有实质感,未抽得液体。右耳、鼻、咽及喉等检查均无异常发现。纯音听力计检查示左耳轻度感音神经性聋(图1)。阻抗测听法检查示两耳A型鼓室     

Primary malignant melanoma of esophagus at esophagogastric junction: case report

Primary malignant melanoma of the esophagus is a rare tumor that accounts for only 0.1% of primary esophageal neoplasms.1 Although it was once thought that primary melanoma could not arise in the esophagus because of the lack of precursor cells, it has since been shown in autopsy series that 4%-8% of individuals have melanoblasts in the esophageal mucosa.2 To date, approximately 200 cases of primary esophageal malignant melanoma have been reported in global literatures while less than 20 cases of primary esophageal malignant melanoma have been reported in China.2-4 In this report we present a case of primary malignant melanoma of the esophagus in a Chinese man.
