概括
大多数丸瘤都是生殖细胞瘤 (GCTs),主要是精髓瘤. 较大的GCT (≥3cm) 显示淋巴/血管入侵和网状丸入侵的比率显著更高,表明风险增加.
科学领域:
- 尿路病理学 尿路病理学
- 在瘤学瘤学.
- 手术病理学手术病理学
背景情况:
- 丸瘤是一个重大的瘤挑战,需要准确的表征来预后评估.
- 形态和免疫组织化学特征对于分类丸瘤和预测患者结果至关重要.
研究的目的:
- 审查丸瘤的形态和免疫组织化学特征.
- 将这些特征与已确定的预后参数进行比较,特别是瘤大小和侵袭模式.
主要方法:
- 在2011年1月至2021年9月期间诊断的丸瘤的回顾性审查.
- 收集的数据包括患者年龄,瘤亚型,大小,扩散,横向化,焦点数和免疫组织化学结果.
- 统计分析的重点是将瘤大小 (尤其是3厘米的切线) 与入侵率相关联.
主要成果:
- 分析了121个丸瘤;108个 (89%) 是生殖细胞瘤 (GCTs),精子瘤占GCTs的52%.
- 淋巴/血管侵袭 (LVI) 和网状丸侵袭在瘤≥3厘米时明显更频繁,相比较小的瘤 (P<0.005).
- 免疫组织化学在确定瘤组件方面非常有价值,特别是在混合的GCT中.
结论:
- 胚胎细胞瘤,特别是精髓瘤,是最常见的丸瘤.
- 瘤大小,特别是超过3厘米,是与增加的淋巴/血管和丸网络入侵相关的关键因素.
- 形态和免疫组织化学分析对于精确诊断和丸瘤的预后分层是必不可少的.

A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.

The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...
