概括
甲状腺内膜内置 (ITIs) 与转移性乳头甲状腺癌 (PTC) 区别于. 免疫组织化学 (IHC) 有助于区分ITI,这些ITI具有较少的经典PTC核特征,并且与复发无关.
科学领域:
- 病理学 病理学 病理学
- 在瘤学瘤学.
- 手术病理学手术病理学
背景情况:
- 在手术病理学中,内甲状腺内置 (ITI) 是一个诊断挑战.
- 区分ITI与转移性乳头甲状腺癌 (PTC) 对于准确的患者管理至关重要.
研究的目的:
- 调查偶然发现的TI的临床病理特征.
- 利用免疫组织化学 (IHC) 来支持TI的诊断和分化.
主要方法:
- 分析了41例在三个手术组中偶然发现的ITI (PTC甲状腺切除术,良性甲状腺疾病,其他头癌).
- 评估ITI形态,包括核心特征.
- 应用BRAF VE1,HBME-1和加勒-3免疫组织化学 (IHC).
主要成果:
- 在4.17%的PTC病例和0.76%的其他头癌病例中发现了ITI.
- 所有的ITI对BRAF VE1,HBME-1和加勒-3 IHC都是负的.
- 与转移性PTC相比,ITI表现出较少的经典PTC核特征 (P < 0.001).
- 在77.3%的相关病例中,在同一淋巴结中观察到ITI和转移性PTC的同时存在.
结论:
- ITI的主要诊断特征包括形态学和特定的IHC标记物 (BRAF VE1,HBME-1,galectin-3).
- 从临床上看,区分ITI与转移性PTC具有重大意义.
- 后续数据表明,ITI与PTC复发没有相关性.

The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Cell Inclusions
Prokaryotic cells possess a variety of inclusions that play crucial roles in nutrient storage, metabolic processes, and environmental adaptation. These structures enable bacteria to thrive under fluctuating environmental conditions by storing essential resources and optimizing their metabolic efficiency.Carbon Storage: Poly-β-Hydroxybutyric Acid and Glycogen GranulesBacteria frequently store excess carbon in specialized granules. Poly-β-hydroxybutyric acid (PHB) granules are lipid polymers that...
