Imaging modalities cannot reliably distinguish between these differentials. The sampling-dependent nature of both cytopathology and core-biopsy histopathology introduces the potential for indeterminate or misleading results. Surgical biopsy can have high complication rates depending on the underlying condition. Here we report the case of a patient with chronic autoimmune thyroid disease who initially presented with fibroinflammatory thyroid disease and was subsequently diagnosed with B-cell lymphoma. This case highlights the diagnostic challenges associated with these conditions, the limitations of the sampling-dependent tissue assessment and the importance of re-evaluating the diagnosis when the clinical course is discordant with the initial biopsy findings.<\/jats:p>","DOI":"10.1210\/jcemcr\/luag285","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T11:21:58Z","timestamp":1788520918000},"source":"Crossref","is-referenced-by-count":0,"title":["Concurrent thyroid and abdominal diffuse large B-cell lymphoma arising in the milieu of chronic fibrosing thyroiditis"],"prefix":"10.1210","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0158-4012","authenticated-orcid":false,"given":"Aleks David","family":"Atrens","sequence":"first","affiliation":[{"name":"Queensland Health Logan Endocrine and Diabetes Service, Logan Hospital, Metro South Health, , Meadowbrook, QLD 4131 ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Hunt","sequence":"additional","affiliation":[{"name":"Queensland Health Logan Endocrine and Diabetes Service, Logan Hospital, Metro South Health, , Meadowbrook, QLD 4131 ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1284-7054","authenticated-orcid":false,"given":"Gaurav","family":"Puri","sequence":"additional","affiliation":[{"name":"Queensland Health Logan Endocrine and Diabetes Service, Logan Hospital, Metro South Health, , Meadowbrook, QLD 4131 ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8220-1302","authenticated-orcid":false,"given":"Kanakamani","family":"Jeyaraman","sequence":"additional","affiliation":[{"name":"Queensland Health Logan Endocrine and Diabetes Service, Logan Hospital, Metro South Health, , Meadowbrook, QLD 4131 ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"80","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"issue":"9","key":"2026100101590527400_luag285-B1","doi-asserted-by":"crossref","first-page":"e3469","DOI":"10.1210\/clinem\/dgaa468","article-title":"Riedel thyroiditis","volume":"105","author":"Zala","year":"2020","journal-title":"J Clin Endocrinol Metab"},{"issue":"10","key":"2026100101590527400_luag285-B2","doi-asserted-by":"crossref","first-page":"3031","DOI":"10.1210\/jc.2011-0617","article-title":"Clinical review: Riedel's thyroiditis: a clinical review","volume":"96","author":"Hennessey","year":"2011","journal-title":"J Clin Endocrinol Metab"},{"issue":"4","key":"2026100101590527400_luag285-B3","doi-asserted-by":"crossref","first-page":"388","DOI":"10.1093\/ajcp\/105.4.388","article-title":"Paucicellular variant of anaplastic thyroid carcinoma.
