The spermatic cords (SCs) obtained from: (a) autopsies of 67 adults and 50 children; (b) 3 fetuses; (c) 12 surgical specimens from 9 adults and 3 children with testicular tumors, and (d) 26 surgical specimens (14 adults and 12 children) with diagnosis of SC cysts, were studied by light microscopy. The histological study revealed the occurrence of tubular embryonal remnants (TERs) in 19 autopsied adults, 14 autopsied children, 3 fetuses, 2 surgical specimens (1 adult and 1 child) owing to testicular tumors, and 6 surgical specimens with diagnosis of SC cysts. The TERs were found in the low, middle or high thirds of the SC and consisted of a cuboidal or columnar, often ciliated epithelium surrounded by connective tissue. In the 3 fetuses and in 3 autopsied children renal glomeruli were found in close relation with the TERs. In 2 cases of SCs showing cysts and TERs both structures contained spermatozoa. The histological pattern of the TERs suggest that they are wolffian derivatives which might give rise to SC cysts.
取自以下样本的精索（SCs）进行了光学显微镜研究：（a）67名成人和50名儿童的尸检样本；（b）3例胎儿样本；（c）9名成人和3名儿童睾丸肿瘤患者的12份手术标本；（d）诊断为精索囊肿的26份手术标本（14名成人和12名儿童）。组织学研究显示，19例成人尸检样本、14例儿童尸检样本、3例胎儿样本、2份因睾丸肿瘤获取的手术标本（1名成人和1名儿童）以及6份诊断为精索囊肿的手术标本中存在管状胚胎残余物（TERs）。TERs位于精索的下三分之一、中三分之一或上三分之一处，由立方或柱状上皮（常为纤毛上皮）及周围结缔组织构成。在3例胎儿样本和3例儿童尸检样本中，发现肾小球与TERs关系密切。在2例同时出现囊肿和TERs的精索样本中，两种结构均含有精子。TERs的组织学模式表明它们是中肾管衍生物，可能会引发精索囊肿。
