概括
本病例报告详细介绍了一种罕见的胃肠外 stromal 瘤 (EGIST) 呈现为 67 岁妇女的急性肌炎. 诊断包括成像和活检,治疗包括手术和针对PDGFRA突变的向治疗.
科学领域:
- 胃肠道学和瘤学
- 手术病理学手术病理学
- 医疗成像医学成像
背景情况:
- 胃肠道 stromal 瘤 (GIST) 起源于胃肠道; 胃肠外 stromal 瘤 (EGIST) 是罕见的,通常无症状,并通过成像和活检诊断.
- GISTs的风险分层取决于瘤大小,线粒细胞发生率,位置和穿孔,指导治疗决策.
- 标准的诊断工具包括计算机断层扫描 (CT) 扫描,组织病理学和免疫化学 (CD117,CD34,DOG1阳性).
研究的目的:
- 报告一种罕见的OMENTAL EGIST病例,该病例呈现出急性肌炎.
- 以不寻常的演示来突出EGISTs的诊断和治疗挑战.
- 强调分子分析在指导GIST的向治疗中的重要性.
主要方法:
- 一个67岁的妇女的病例介绍,她的症状暗示着肌炎.
- 诊断工作包括腹部检查,血液分析,腹部CT扫描和CT导向活检.
- 组织病理学和免疫组织化学分析证实了GIST,随后进行了手术切除和基因检测.
主要成果:
- 患者出现左侧腹部疼痛,墨菲征兆,贫血,功能障碍,白细胞症和C反应蛋白升高.
- 腹部CT显示异质质量;活检证实表皮质GIST阳性CD117和DOG1.1.
- 组织学显示,一个大,高等级的上皮状GIST起源于一个PDGFRA基因变异的形象体.
结论:
- 这一案例强调了在异常表现的患者中考虑EGIST等罕见诊断的重要性.
- 准确的诊断和风险分层,包括分子分析,对于有效管理GISTs至关重要.
- 手术切除结合分子向疗法,例如PDGFRA突变的伊马替尼,为高风险的GIST提供了一个有希望的治疗策略.

2.4K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

01:12Internal Anatomy of the Kidney
1.6K
The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
