“…To study the organs in which LR can be formed, we reviewed the English‐language literature regarding LR in a PubMed search encompassing the years 1987–2008. The results are summarized in Table 1 2–19,27–36 . As described here, LR were frequently seen in the kidney ( n = 25) and breast ( n = 22), followed by synovium ( n = 8), female genital tract ( n = 8), and eyelid and conjunctiva ( n = 4).…”

“…Diagnostic procedure was recorded in 77 cases, and LR were most commonly diagnosed using surgical specimens ( n = 38), followed by fine‐needle aspiration ( n = 32). Occasionally, LR present as a tumor‐like mass, and in these instances clinical suspicion of malignancy can arise, as occurred in the present case 2–4,9,12,27–29,32,33,36 . On immunohistochemistry there is no reliable marker for diagnosis of LR, but in some cases LR have contained calcium, hemosiderin, glycogen, acid mucopolysaccharide, and amyloid 2,5,9,12,28,29,32,34,35 …”

Liesegang rings (LR) are acellular, laminated structures that may be deposited within and around cysts and inflamed or necrotic tissue. Previous reports have shown that the kidney and breast are commonly affected organs of LR. Herein is reported a rare case of biliary deposition of LR presenting as a tumor-like polypoid mass in the liver. A 70-year-old man was found to have a cystic lesion, measuring 3.0 cm in diameter, in the lateral segment of the liver. The lesion was accompanied by a solid mass, 1.8 cm in diameter, within the cystic cavity. Lateral segmentectomy of the liver was performed because clinical examinations could not exclude the possibility of hepatobiliary cystadenoma or cystadenocarcinoma. Pathology of the resected specimen indicated a soft polypoid mass, connecting to the cystically dilated bile duct with elongated stalk-like structures. Histologically the surface of the mass was covered by non-neoplastic biliary-type epithelium. Beneath the epithelium, extensive deposition of numerous ring-like laminated structures, which exhibited an identical appearance to LR, was observed. This is a unique and previously unrecognized lesion involving the occurrence of LR deposition in the hepatobiliary tracts, which further formed a grossly visible mass resembling a hepatic tumor.

Liesegang rings are concentric noncellular lamellar structures, rarely seen in vivo, occurring as a consequence of the accumulation of insoluble products in a colloidal matrix. These characteristic structures are a rare phenomenon usually found in association with cystic or inflammatory lesions and may be mistaken for parasites. The authors examined Liesegang rings from an inflammatory kidney lesion identified previously as a tumoral lesion on computerized tomography. On microscopic evaluation, Liesegang rings can be mistaken for eggs and larvae of parasites, psammoma bodies and calcification. Special stains like PAS, Grocott, von Kossa and Masson's trichrome facilitate the diagnosis.

“…A few cases have been described more rarely in the maxillary sinus, pleura, peritoneus (endometrium), omentum, pericardium, epididymus, and fallopian tubes. They have been confused with material extraneous, various parasites (such as Dioctophyma renale or Echinoccoccus), eggs, larva, (monorifrangent cellular structures, clear, with regular borders and homogeneous composition), algas, psammoma bodies, aspecific calcifications, corpora amilacea (concretions of calcium, found in prostate, brain, and lung but not associated to inflammatory processes), bodies of Guttman-Michaelis (concretions of calcium and iron, recovered in the bladder (urinaria), characterized from concentric and in partnership laminations to inflammatory events) [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The presence of LRs in biopsy specimen is an occasional finding, because the exact mechanism of formation and composition of these peculiar rings is unknown.…”

“…So far, the nature of the material of composition of the LRs and their pathogenesis are unknown. In human tissues, several involved physical-chemical factors related to temperature, pH, electric position, concentration of the reagents, chemical stoichiometry, flocculation values, typology of the substrate, and ability to influence the reaction have not been yet decoded and characterized [1,4,6].…”

Liesegang rings are concentric noncellular lamellar structures, occasionally found in inflammatory tissues. They have been confused with various parasites, algas, calcification, and psammoma bodies. The authors examined Liesegang rings from oral inflammatory cysts by both optical and confocal laser scanning microscopy, and perfomed a three-dimensional reconstruction. These investigations indicate that Liesegang rings are composed of multiple birefringent concentric rings, resulting from a progressive deposition of organic substances, with an unclear pathogenesis.
