概括

恶性子宫周血管上皮质细胞瘤 (PEComas) 是罕见的,具有不同的特征和诊断挑战. 针对性疗法在晚期病例中表现有前途,但特定的标志物仍然难以捉摸.

科学领域:

妇科瘤学妇科瘤学
病理学病理学病理学
医疗成像医学成像

背景情况:

周周血管上皮质细胞瘤 (PEComas) 通常是具有黑色细胞和肌原性标记的良性瘤.
恶性PEComa很少见,它们与光滑肌肉瘤的区别可能具有挑战性.
这份报告详细介绍了两个晚期恶性子宫PEComa的病例.

研究的目的:

报告两个晚期恶性子宫PEComa的病例.
讨论临床病理学特征,诊断困难和治疗结果.

主要方法:

关于两名患有晚期子宫PEComa的患者的病例报告.
使用成像,病理诊断和免疫组织化学 (HMB-45,H-Caldesmon).
一名患者接受了向辅助疗法 (基于MTOR抑制剂).

主要成果:

案例1:一名74岁的女性患有大量死体质,诊断出患有类似PEComa特征的肉瘤.
案例2:一名50岁的女性患有子宫质量和转移,被诊断为第四级PEComa (TP53,ATRX,TSC1突变).
病例2患者在8个月的向治疗后没有出现复发.

结论:

转移性PEComa表现出不同的临床病理特征.
在PEComas和光滑肌肉瘤之间存在诊断重叠.
目前还没有确定PEComa的确切诊断标志物.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
