We report a case of detached ciliary tufts (DCTs) discovered in the aspirate from an epididymal cyst in a 30-year-old man undergoing epididymal exploration for obstructive azoospermia. The specimen was initially misdiagnosed as a parasite due to its appearance and spontaneous motion on fresh smear. Since standard urology and histology texts identify ciliated cells only in the efferent duct of the male genital tract, the source of DCTs in this patient was mysterious. However, on further review, histologic studies have demonstrated that the first portion of the epididymis represents an extension of the efferent ducts and is lined with cilia. The fact that the caput epididymis is composed of branched efferent ducts has significant implications for our understanding of congenital absence of the vas, epididymal sperm aspiration, spermatoceles, and epididymal physiology.
我们报告了一例在一名30岁男性附睾囊肿抽吸物中发现的睫状突脱离（DCTs）病例，该男性因梗阻性无精子症接受附睾探查。由于其在新鲜涂片上的外观和自发运动，该标本最初被误诊为寄生虫。由于标准的泌尿学和组织学文献仅在男性生殖道的输出小管中识别出纤毛细胞，因此该患者DCTs的来源成谜。然而，进一步检查发现，组织学研究表明，附睾的第一部分是输出小管的延伸，内衬纤毛。附睾头由分支的输出小管组成这一事实，对我们理解先天性输精管缺如、附睾精子抽吸、精液囊肿和附睾生理学具有重要意义。
