摘 要:目的:探讨原发性睾丸混合性生殖细胞肿瘤(MGCT)的临床病理特征。方法:对我院13例原发性睾丸MGCT患者的临床病理资料进行回顾性分析,并结合相关文献进行讨论。结果:睾丸MGCT占我院同期睾丸生殖细胞肿瘤的24.1%(13/54),患者年龄2~53岁,平均28.3岁。全部病例均发生于单侧睾丸,左侧6例,右侧7例,左右侧比为0.86:1。睾丸MGCT病理形态多样,肿瘤成分包括胚胎性癌(11例,84.6%)、精原细胞瘤(8例,61.5%)、畸胎瘤(6例,46.2%)、绒毛膜癌及卵黄囊瘤(均为4例,23.1%)。其中9例(69.2%)包含2种不同的生殖细胞肿瘤成分,3例(30.8%)包含3种不同的肿瘤成分,1例(7.7%)包含5种不同的肿瘤成分。结论:睾丸MGCT非常少见,好发于青壮年男性,不同的肿瘤成分其生物学行为、临床治疗和预后不同,因此准确的病理诊断非常必要,免疫组化标记对病理诊断与鉴别诊断具有重要作用。Objective: To investigate the clinicopathological characteristics of primary testicular mixed germ cell tumor (MGCT). Methods : We retrospectively analyzed the clinicopathological data of 13 cases of primary testicular MGCT and reviewed other relevant literature. Results: MGCT accounted for 24.1% (13/54) of all the testicular germ cell tumors diagnosed in our hospital. The patients ranged in age from 2 to 53 years, averaging at 28.3 years. All were unilateral cases, 6 in the left and 7 in the right testis, with a left/right ratio of 0.86: 1. Morphologically, testicular MGCT displayed a variety of subtypes, embryonal carcinoma in 11 cases (84.6%), seminoma in 8 (61.5%), teratoma in 6 (46.2%), choriocarcinoma in 4 (30.8%) and yolk sac tumor in 4 (30.8%). Nine of the cases (69.2%) were composed of two different germ cell histological elements, 3 (23.1%) composed of three, and 1 (7.7%) composed of five. Conclusion : Testicular MGCT is rather rare and most commonly occurs in young men. Its biological behavior, clinical management and prognosis vary with its different histological elements. Therefore accurate pathological diagnosis is essential and immunohistochemistry plays an important role in the diagnosis and differential diagnosis of testicular MGCT.
