Ringlike structures of various sizes, resembling Liesegang rings (LRs), were found in the needle aspirate from a breast cyst in an elderly woman. They were characterized by a double-layer outer wall with striations and an amorphous central nidus. Immunohistochemical stains for calcium, iron, mucus, glycogen, amyloid, cytokeratin and epithelial membrane antigen yielded negative results. Since LRs can be mistaken for ova, larvae or parasites, it is important that cytologists be aware of their occurrence, albeit infrequent, in aspirated material to avoid a misdiagnosis.
在一位老年女性乳腺囊肿的针吸物中发现了各种大小的环状结构，类似于李泽冈环（LRs）。它们的特征是具有带条纹的双层外壁和无定形的中央核。钙、铁、黏液、糖原、淀粉样蛋白、细胞角蛋白和上皮膜抗原的免疫组织化学染色结果均为阴性。由于LRs可能被误认为是卵子、幼虫或寄生虫，因此细胞学家必须了解它们在吸出物中虽不常见但仍会出现的情况，以避免误诊。
