摘要
目的研究睾丸精原细胞瘤的形态学,探讨该肿瘤的病理诊断及鉴别诊断。方法对25例成人睾丸精原细胞瘤形态和组织类型作回顾性分析。结果患者年龄23～71岁,平均41.4岁。均累及单侧睾丸,右侧多见(17/25)。其中1例合并胚胎癌、2例合并胚胎癌及畸胎瘤存在。有隐睾史者3例。结论成年人出现睾丸无痛性、进行性睾丸肿大,应考虑到该肿瘤的可能。睾丸精原细胞瘤原因不明,隐睾是其危险因素之一。肿瘤的确诊依赖于光镜下组织病理学形态,辅以免疫组织化学。
Objective To study morphological features of testicular seminoma in adult and discuss its diagnosis and differential diagnosis. Methods Histologic patterns and morphologic characteristics of 25 cases with testicular seminoma based on the formalin-fixed, paraffin- embedded and hematoxylin-eosin stained tissue in adult were analyzed retrospectively. Results Of the 25 cases aged 23-71 years old （averaged 41.4）, 17（68.0%） cases were located at the right testis, and 8 （32.0%） cases located at the left one. Of whom, 1 case combined with embryonal carcinoma and 2 cases combined with embryonal carcinoma and teratoma, 3 cases had a history of cryptorehidism. Conclusion Painless tumescence of a testicle is the most common manifestation of the testicular seminoma. The cause of testicular seminoma is unknown, history of cryptorehidism is one of the risk factors, and the final diagnosis relys on the pathological examination. The feature of testieular seminoma is that fibrous bands infiltrated with lymphocytes separate regular clear polyhedral cells.
