概括

脂质母细胞瘤样瘤 (LLTs) 是一种罕见的瘤. 准确的诊断需要仔细的组织病理学和分子评估,手术切除作为主要治疗方法.

科学领域:

在瘤学瘤学.
病理学病理学病理学
皮肤病学皮肤病学

背景情况:

脂质母细胞瘤样瘤 (LLTs) 是一种罕见的脂肪细胞瘤,通常出现在部区域.
他们的诊断是具有挑战性的,因为其与其他脂肪细胞瘤的遗传病理和分子特征重叠.
需要仔细区分LLT与脂质母细胞瘤,状脂质肉瘤,状细胞脂瘤和非典型的状细胞/多形脂质瘤 (ASCPLT).

研究的目的:

在部区域报告一种类似于脂质母细胞瘤的瘤病例.
突出与LLTs相关的诊断挑战.
强调准确的组织病理学和分子评估对于适当的管理的重要性.

主要方法:

一个41岁的女性的病例报告,她有一个体质量.
最初的切除活检和随后的广泛局部切除.
组织病理学检查,免疫组织化学 (CD34,S100) 和分子分析 (DDIT3重新排列).

主要成果:

瘤的特征是状细胞在状层中,具有焦点CD34和S100阳性.
证实没有DDIT3重组.
广泛的局部切除实现了负边际,在24个月的随访期间没有复发.

结论:

准确的LLT诊断依赖于全面的免疫组织化学和分子分析,特别是缺乏DDIT3和PLAG1重组.
清晰边缘的外科切除是LLT的首选治疗方法.
由于复发或转移的罕见可能性,建议进行长期监测.

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
