Cryptorchidism is a common malformation in neonates; surgery or medical treatments are applied during childhood. Untreated cryptorchid testes are in the risk of intratubular germ cell neoplasia (IGCN) and consequently invasive testicular tumors which could be shown by immunohistochemistry staining for placental like acid phosphatase (PLAP) marker.
We designed this study to know the prevalence of IGCN in untreated cryptorchid testes of infertile men, in our infertility center as a refferal center.
In this cross-sectional study we assessed H&E slides of testicular samples of 13 adult infertile patients with impalpable intra-abdominal testes seeking infertility treatment; then we stained them by PLAP marker.
Three (23.08%) samples were positive for PLAP marker means presence of IGCN in testis. One of them showed seminoma besides IGCN.
According to the results of this study and the fact that there are adult untreated cryptorchid patients in our country yet, it is suggested to pay more attention in clinical examination, assessment and follow up of such patients for malignancy screening.
隐睾症是新生儿常见的畸形;在儿童期需进行手术或药物治疗。未经治疗的隐睾有发生管内生殖细胞瘤(IGCN)的风险,进而可能发展为侵袭性睾丸肿瘤,这可通过胎盘样酸性磷酸酶(PLAP)标记物的免疫组化染色显示。
我们设计本研究以了解在作为转诊中心的我们的不孕不育中心,不育男性未经治疗的隐睾中IGCN的患病率。
在这项横断面研究中,我们评估了13例寻求不孕不育治疗且无法触及的腹腔内睾丸的成年不育患者的睾丸样本的苏木精-伊红(H&E)切片;然后用PLAP标记物对其进行染色。
3份(23.08%)样本PLAP标记物呈阳性,意味着睾丸中存在IGCN。其中1份除IGCN外还显示为精原细胞瘤。
根据本研究结果以及我国仍有成年隐睾未治疗患者这一事实,建议在临床检查、评估及此类患者的随访中更加关注恶性肿瘤筛查。
