目的:报道1例AA型系统性淀粉样变性患者的临床资料和病理资料,分析该病例特殊表现,总结淀粉样变性常见的临床表现及诊治要点。方法:回顾性分析1例表现为腹部淀粉样瘤及多系统功能异常的AA型系统性淀粉样变性患者的临床资料及诊治过程,... 目的:报道1例AA型系统性淀粉样变性患者的临床资料和病理资料,分析该病例特殊表现,总结淀粉样变性常见的临床表现及诊治要点。方法:回顾性分析1例表现为腹部淀粉样瘤及多系统功能异常的AA型系统性淀粉样变性患者的临床资料及诊治过程,结合该例患者的临床资料及诊治过程进行文献复习,明确淀粉样变性的临床特点、诊治要点。结果:该例患者为一名62岁女性,自2012年开始相继出现四肢麻木、贫血、食欲下降、腹泻、水肿、蛋白尿及肾功能不全等多系统病变的症状。既往有"肺结核、胸椎结核"病史。病程中检查发现:重度缺铁性贫血,肾病综合征,血肌酐258μmol/L,球蛋白升高;血沉快,血轻链κ/λ比值为1.39,其他免疫学检查均阴性;骨髓细胞学检查未见异常增殖浆细胞;影像学示左下腹部一卵圆形大肿块,腹膜后多发淋巴结肿大;结肠镜检诊断为糜烂性结肠炎;腹部肿块、结肠粘膜及肾脏穿刺病理最终确诊考虑为结核感染导致AA型系统性淀粉样变性。结论:系统性淀粉样变性临床表现多样、缺乏特异性,因此常常被误诊或漏诊。本病例患者除了多系统受累的临床表现外,更为特殊的是在患者的腹部出现了一淀粉样物质所构成的淀粉样瘤,这种少见的临床表现很容易被误诊为肿瘤而延误诊治。因此,及时对该类患者进行组织活检,通过病理学及特殊染色将有助于系统性淀粉样变性的早期诊断,减少及延缓并发症的发生。 展开更多

Localized amyloidosis is characterized by amyloid protein deposition restricted to one organ or tissue without systemic involvement. Gastrointestinal manifestations of localized amyloidoma are unusual, which makes amyloidoma restricted to the rectum a very rare diagnosis requiring a high index of suspicion. We present a rare account for rectal amyloidoma with an unusual presentation of obstructive symptoms and its treatment using a sophisticated surgical modality, transanal endoscopic microsurgery(TEM), which resulted in complete excision of the lesion without hospitalization and complications. The successful treatment for thisrectal amyloidoma using TEM emphasizes the need to broaden its application in the treatment of various rectal lesions while preserving organ function and decreasing recurrence. 展开更多

Amyloidosis is commonly systemic,occasionally organlimited,and rarely a solitary localized mass.The latter,commonly referred to as tumoral amyloidosis,is described as occurring in nearly every organ/tissue.Only a few reports of gastric amyloidosis exist today.We describe a 72 year-old black male from Barbados presenting with 3 d of diffuse abdominal pain.His medical history included Non-Hodgkin’s Lymphoma diagnosed five years ago,status-post six rounds of cyclophosphamide,adriamycin,vincristine,prednisone chemotherapy,and currently was in remission.On computed tomography scan of the abdomen,thickening and calcification of the gastric wall was noted along with pneumatosis.On esophagogastroduodenoscopy,a large circumferential friable mass was seen from the gastroesophageal junction to the body.A large nonbleeding 3 cm polyp was also seen in post bulbar area of duodenum.Biopsies were stained with Congo red and gave green birefringence under polarized light,consistent with tumoral amyloidosis.Positron emission tomography scan revealed diffuse gastric mucosa uptake compatible with gastric malignancy without metastatic foci.Treatment for gastric amyloidomas has presently been one of observation or,at most,resection of the amyloid mass.It is not known if our patient required the same approach or if this warranted the re-institutionof chemotherapy for Non-Hodgkin’s Lymphoma.Until more reports of tumoral amyloidosis are made known,treatment as well as prognosis remain uncertain. 展开更多

A male of 52-yearold with a recurrent mass in the nasopharynx underwent surgical resection 2 years ago. Immunohistochemical examination revealed M protein band and kappa immunoglobulin light chain. The sections of the biopsy of the mass in the nasopharynx and anterior abdominal wall were stained with Congo red and examined with microscopy. Amyloid deposits were found. It was diagnosed as systemic amyloidoma. Colchicine, melphalan and prednisone were administered. The mass decreased its size in the 8 months of follow-up. This case suggests that a solitary tumor in the nasopharynx might be an early sign of systemic amyloidosis because of the slow progression of the disease. The existence of a solitary amyloidoma in any location of the body should lead the doctor to look for other symptoms and signs of systemic amyloidosis. 展开更多
