病理学病理学病理学
在瘤学瘤学.

背景情况:

饥饿和营养不良会导致器官的退行性变化.
脂肪组织中的这些组织学发现可以被误认为是瘤,使诊断复杂化.

研究的目的:

报告16例偶然发现的腹部脂肪组织退行性变化的病例.
突出诊断挑战,并为这些病变提出一致的命名法.

主要方法:

追溯对16例腹部脂肪组织偶发性退行性变化的病例进行了审查.
组织学检查和免疫组织化学 (S100蛋白,细胞胺).

主要成果:

病变发生在各种腹部部位 (结肠,小肠,大肠等). ) 的情况.
组织学显示,缩脂肪具有类似密封环的脂肪细胞和myxoid stroma.
免疫组织化学检测结果对S100呈阳性,对细胞激素呈阴性.
差异性诊断包括结环细胞癌,脂质肉瘤和血管病变.

结论:

退行性脂肪缩可以模仿瘤过程,导致诊断混乱.
为了一致性,建议使用术语"伪新生体脂肪缩".
准确的鉴定至关重要,以避免误诊和不必要的治疗.

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
