To describe a case of crossed testicular ectopia that was diagnosed in a 52-year-old patient who had consulted for infertility associated with a genital anomaly.
Patient evaluation included hematological, hormonal, cytogenetic and imaging studies. An exploratory operation was also performed.
The hematological, hormonal and cytogenetic studies gave normal results. There were no urinary tract abnormalities in the intravenous urography; retrograde urethrography disclosed a narrow duct behind the urethra that ascended towards the left inguinal duct and divided into two epididymides after reaching the scrotum. Surgical exploration showed two testes in the left scrotal pouch that were biopsied. Histological examination revealed an almost complete hyalinization of the tubular wall with no germ cells within the tubules.
Crossed testicular ectopia is one of the most uncommon testicular anomalies and is often associated with other disorders such as inguinal hernia, hypospadias, pseudohermaphroditism and scrotal abnormalities. Like all dysgenetic testes, progression to malignancy is relatively frequent. The foregoing should be remembered when dealing with these patients.
描述一例交叉睾丸异位病例，该病例发生在一名52岁因生殖器异常导致不育前来咨询的患者身上。
对患者进行了血液学、激素、细胞遗传学和影像学检查。还实施了探查手术。
血液学、激素和细胞遗传学检查结果均正常。静脉肾盂造影未发现泌尿系统异常；逆行尿道造影显示尿道后方有一条狭窄管道，向上通向左侧腹股沟管，到达阴囊后分成两个附睾。手术探查发现左侧阴囊袋内有两个睾丸，并对其进行了活检。组织学检查显示管壁几乎完全玻璃样变，小管内无生殖细胞。
交叉睾丸异位是最罕见的睾丸异常之一，常与腹股沟疝、尿道下裂、假两性畸形和阴囊异常等其他疾病相关。与所有发育不全的睾丸一样，发生恶性病变的情况相对常见。在处理这些患者时应牢记上述情况。
