The cytologic overlap between benign M\u00fcllerian inclusions and PTC features adds complexity, especially in unusual locations. A 45\u2010year\u2010old woman with a history of ovarian serous borderline tumor (SBT) and non\u2010invasive M\u00fcllerian implants presented with cystic lymphadenopathy in the neck. Imaging revealed multiple suspicious, partially cystic lymph nodes. Fine\u2010needle aspirations (FNA) from two nodes showed moderate cellularity, monolayered epithelial sheets, and nuclear features suggestive of PTC. FNA cytology, thyroglobulin level, and immunocytochemical profile revealed benign M\u00fcllerian cells within lymph nodes. Subsequent histologic evaluation of the excised lymph nodes confirmed cystic endosalpingiosis. This case emphasizes the value of comprehensive clinical\u2010pathologic correlation and appropriate ancillary studies in the evaluation of cystic lymphadenopathy. Awareness of benign M\u00fcllerian inclusions and their mimicry of metastatic disease is essential for accurate diagnosis and optimal patient management.<\/jats:p>","DOI":"10.1002\/dc.25430","type":"journal-article","created":{"date-parts":[[2024,12,16]],"date-time":"2024-12-16T11:34:31Z","timestamp":1734348871000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Bilateral Cystic Endosalpingiosis in Cervical Lymph Nodes Mimicking Metastatic Papillary Thyroid Carcinoma Morphologically on Cytology: A Case Report and Literature Review of Diagnostic Challenges"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8369-4711","authenticated-orcid":false,"given":"Elizabeth","family":"Davaro","sequence":"first","affiliation":[{"name":"Division of Pathology and Laboratory Medicine The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prih","family":"Rohra","sequence":"additional","affiliation":[{"name":"Division of Pathology and Laboratory Medicine The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2555-3480","authenticated-orcid":false,"given":"Uma","family":"Kundu","sequence":"additional","affiliation":[{"name":"Division of Pathology and Laboratory Medicine The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6563-5611","authenticated-orcid":false,"given":"Qiong","family":"Gan","sequence":"additional","affiliation":[{"name":"Division of Pathology and Laboratory Medicine The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,16]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000261"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e3182237985"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0000000000001645"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/ddg.14521"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.12659\/AJCR.926094"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.2840080621"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/tbj.13539"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1524-4741.2011.01081.x"},{"issue":"9","key":"e_1_2_8_10_1","first-page":"841","article-title":"Benign Mullerian Lymph\u2010Node Inclusions \u2010 An Unusual Case With Implications for Pathogenesis and Review of the Literature","volume":"119","author":"Henley J.
