In some smears from prostatic aspirates we have observed atypical epithelial cells similar to those of seminal vesicles; however, the site of aspiration was nowhere close to the seminal vesicles. We presumed those cells corresponded to ejaculatory duct epithelium. To confirm this assumption, we compared the cytology of seminal vesicles and ejaculatory ducts based on smears obtained from 10 autopsy cases. The aspects analyzed were types and arrangements of the cells, cytoplasmic and nuclear features, presence of pigment, and background of the smear. The only differences observed were the greater amounts of proteinaceous material in smears from seminal vesicles and the presence of transitional epithelial cells in smears from ejaculatory ducts. We would like to make pathologists aware of atypical cells from ejaculatory ducts as a source of diagnostic difficulties in prostatic aspirates. This subject has received no attention in the literature.
在一些前列腺穿刺涂片标本中，我们观察到了与精囊上皮细胞相似的非典型上皮细胞；然而，穿刺部位与精囊毫无毗邻关系。我们推测这些细胞相当于射精管上皮细胞。为证实这一推测，我们基于10例尸检病例的涂片，对精囊和射精管的细胞学特征进行了比较。分析的方面包括细胞类型和排列、细胞质和细胞核特征、色素的存在以及涂片背景。观察到的唯一差异是精囊涂片中有更多的蛋白质物质，以及射精管涂片中有移行上皮细胞。我们希望病理学家注意到射精管的非典型细胞，它们是前列腺穿刺诊断困难的一个来源。这一主题在文献中尚未受到关注。
