Periodic structures with equally spaced radial striations, identified as Liesegang-like rings, were encountered in fine needle aspirates of two patients' hemorrhagic renal/perirenal cysts. The patients, one 60 and the other 39 years old, had acute right-flank pain; both underwent nephrectomy. The ring structures ranged in size from 8 microns to 200 microns in diameter and had regularly striated double walls. Histochemical and immunoperoxidase tests for iron, calcium, mucopolysaccharides, amyloid, keratin and hemoglobin performed on the tissue sections of the resected specimens gave negative results. With electron microscopy, the ring structures of one of the cases displayed a fine fibrillary composition. Since these Liesegang-like structures may be mistaken for parasites or necrotic tissue, pathologists should be aware of them. To our knowledge, this is the first report of Liesegang-like rings in the cytology literature.
在两名患者出血性肾/肾周囊肿的细针穿刺抽吸物中发现了具有等距径向条纹的周期性结构，被鉴定为类李塞根环。患者一名60岁，另一名39岁，均有急性右侧腰痛；两人均接受了肾切除术。这些环状结构的直径范围为8微米至200微米，具有规则条纹的双层壁。对切除标本的组织切片进行的铁、钙、粘多糖、淀粉样蛋白、角蛋白和血红蛋白的组织化学和免疫过氧化物酶检测均为阴性结果。通过电子显微镜观察，其中一例的环状结构显示出精细的纤维成分。由于这些类李塞根结构可能被误认为是寄生虫或坏死组织，病理学家应予以注意。据我们所知，这是细胞学文献中关于类李塞根环的首次报道。
