Light microscopy study of spermatic cord cysts in 26 men revealed three different histological patterns. First, cysts of probable mesothelial origin (14 cases) with an unilocular aspect: their epithelial cells showed poor cohesion and often appeared sloughed; subepithelial hyalinization or fibrin deposits were frequent. Second, cysts of probable embryonal (mesonephric) origin (8 cases): they were usually multilocular cysts and their epithelial cells showed great cohesion: zones of ciliated columnar epithelium associated with embryonal remnants displaying a similar epithelium were often found; the embryonal remnants and the cyst lumen contained spermatozoa in 2 cases. Third, cysts of doubtful origin (4 cases) showing abundant inflammatory infiltrates, which had destroyed the epithelium; the unilocular pattern observed in 3 cases suggests a mesothelial origin for these cysts, while the multilocular pattern and presence of embryonal remnants in the other case suggest an embryonal origin.
对26名男性精索囊肿进行的光学显微镜研究揭示了三种不同的组织学模式。首先，可能起源于间皮的囊肿（14例），呈单房性：其上皮细胞黏附性差，常呈脱落状；上皮下透明变性或纤维蛋白沉积常见。其次，可能起源于胚胎（中肾）的囊肿（8例）：通常为多房性囊肿，其上皮细胞黏附性强；常发现与显示类似上皮的胚胎残余物相关的纤毛柱状上皮区域；2例中胚胎残余物和囊肿腔内含有精子。第三，起源不明的囊肿（4例），有大量炎性浸润，破坏了上皮；3例观察到的单房模式提示这些囊肿起源于间皮，而另一例中的多房模式和胚胎残余物提示起源于胚胎。
