Fine\u2010needle aspiration cytology is one of the primary diagnostic procedures for determining the nature of suspicious thyroid nodules. Clinical information is particularly important during cytomorphological evaluation, especially in patients with a history of hematological malignancy. We report a case of a 58\u2010year\u2010old woman diagnosed with CLL, presenting with thyroid gland involvement 8\u2009years after the initial diagnosis. Fine\u2010needle aspiration cytology revealed an infiltrative cellular smear with coarse chromatin and monomorphic cells displaying a tortoise shell pattern within a colloid\u2010containing background. Diagnostic confirmation was achieved through flow cytometric analysis of the aspirated fluid material. In patients with a history of hematologic malignancy, careful evaluation is required when a lymphocytic background is observed in aspirations, and additional methods should be employed if necessary. Distinguishing between primary and secondary lymphomas of the thyroid gland is clinically significant, as their treatment and prognosis differ substantially.<\/jats:p>","DOI":"10.1002\/dc.25476","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T03:33:02Z","timestamp":1744687982000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Thyroid Infiltration by Chronic Lymphocytic Leukemia: A Rare Case Report With Cytological and Flow Cytometry Findings"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9310-9181","authenticated-orcid":false,"given":"Nursinem Alkan","family":"Vur\u011fun","sequence":"first","affiliation":[{"name":"Department of Medical Pathology Y\u00fcksekova State Hospital, Hakkari  Hakkari Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nagihan","family":"Yal\u00e7\u0131n","sequence":"additional","affiliation":[{"name":"Department of Medical Pathology Pamukkale University  Denizli Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nilay \u015een","family":"T\u00fcrk","sequence":"additional","affiliation":[{"name":"Department of Medical Pathology Pamukkale University  Denizli Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Semin Melahat","family":"Fenkci","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Pamukkale University  Denizli Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00fcls\u00fcm Akg\u00fcn","family":"\u00c7a\u011fl\u0131yan","sequence":"additional","affiliation":[{"name":"Department of Hematology Pamukkale University  Denizli Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4,15]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1089\/thy.1999.9.1273"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1089\/thy.2010.0089"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1590\/2359-3997000000034"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11864-004-0021-7"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2303.2001.00338.x"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/1756-6614-6-1"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.2478\/folmed-2018-0077"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(196205\/06)15:3<557::AID-CNCR2820150315>3.0.CO;2-H"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.23748"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.20894"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcte.2020.100221"},{"key":"e_1_2_10_13_1","volume-title":"Presented at: 84th Annual Meeting of the American Thyroid Association","author":"Tuttle R.
