Peculiar ring-like structures identified as Liesegang rings (LRs) were found in renal cyst fluid from three patients with benign renal cysts. They ranged in size from 5 to 820 mu. Most had a double-layer outer wall with equally spaced radial cross-striations and an amorphous central nidus. Special stains were performed in one case, and the results are discussed. Reports of LRs in cystic or inflamed tissues have recently appeared in the literature. Some LRs have been mistaken for eggs or mature components of the giant kidney worm, Dioctophyma renale. We propose that cytologic assessment of renal cyst fluid in conjunction with histologic examination decreases the likelihood of misdiagnosis of LRs.
在三名患有良性肾囊肿患者的肾囊肿液中发现了被鉴定为李塞冈环（LRs）的特殊环状结构。它们的大小从5到820微米不等。大多数有双层外壁，有等间距的放射状横纹和无定形的中央核。对其中一例进行了特殊染色，并讨论了结果。最近文献中出现了关于囊性或炎症组织中李塞冈环的报道。一些李塞冈环被误认为是巨大肾虫（肾膨结线虫）的卵或成熟成分。我们建议，结合组织学检查对肾囊肿液进行细胞学评估可降低李塞冈环误诊的可能性。
