Liesegang rings are eosinophilic, concentric, lamellated structures that can assume a variety of shapes and sizes ranging from a few microns to hundreds of microns. To date, Liesegang rings have been reported in around 30 examples in the English literature, in the kidney, breast, female genital tract, and skin, and only a single report in the lung associated with allergic bronchopulmonary aspergillosis. Liesegang rings are usually incidental discoveries and have been associated with benign cystic lesions, inflammatory diseases, fibrosis, and tissue necrosis. Their typical appearance helps differentiate them from their mimics including parasites, foreign materials, corpora amylacae, and psammoma bodies. We report Liesegang rings in a 62-year-old male patient with pulmonary tuberculosis to create awareness about this rare entity among pathologists to avoid its misdiagnosis as a parasitic infection.
李泽冈环是嗜酸性、同心、分层的结构，其形状和大小各异，范围从几微米到数百微米。迄今为止，英文文献中已报道约30例李泽冈环，见于肾脏、乳腺、女性生殖道和皮肤，仅有1例报道于肺部，与变应性支气管肺曲霉病相关。李泽冈环通常为偶然发现，与良性囊性病变、炎症性疾病、纤维化和组织坏死有关。其典型表现有助于将它们与包括寄生虫、异物、淀粉样小体和砂粒体在内的模仿物区分开来。我们报告了1例62岁男性肺结核患者出现李泽冈环的情况，以提高病理学家对这一罕见实体的认识，避免将其误诊为寄生虫感染。
