We present a patient with SAT and papillary thyroid cancer that was suspected by ultrasonographic evaluation (US) following SAT treatment. A fifty-four-year old female patient referred to our department due to tachycardia, jitteriness and pain in cervical region for the past one month. SAT diagnosis was established by physical examination, laboratory and ultrasonographic findings. After treatment, control thyroid US revealed regression of the hypoechogenic regions seen in both lobes, and a previously unreported hypoechogenic lesion with microcalcification focus that had irregular borders and was not clearly separated from the surrounding parenchyma located in the posterior aspect of the lobe (Elasto score: 4, Strain index: 7.08). Fine needle aspiration biopsy was taken from this nodule; cytology was assessed to be compatible with papillary thyroid carcinoma. Postsurgical pathology evaluation showed a papillary microcarcinoma. SAT may produce ultrasound changes that obscure the coexistence of papillary carcinoma. We recommend that patients with SAT have ultrasonography after they recover. Hypoechogenic regions bigger than 1 cm that are present in the follow-up post-therapy US should be assessed by biopsy.<\/jats:p>","DOI":"10.1590\/0004-2730000003222","type":"journal-article","created":{"date-parts":[[2014,11,29]],"date-time":"2014-11-29T18:25:38Z","timestamp":1417285538000},"page":"851-854","source":"Crossref","is-referenced-by-count":15,"title":["Papillary thyroid cancer case masked by subacute thyroiditis"],"prefix":"10.1590","volume":"58","author":[{"given":"Bekir","family":"Ucan","sequence":"first","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tuncay","family":"Delibasi","sequence":"additional","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erman","family":"Cakal","sequence":"additional","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muyesser Sayki","family":"Arslan","sequence":"additional","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nujen Colak","family":"Bozkurt","sequence":"additional","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taner","family":"Demirci","sequence":"additional","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa","family":"Ozbek","sequence":"additional","affiliation":[{"name":"Diskapi Yildirim Beyazit Training and Research Hospital, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa","family":"Sahin","sequence":"additional","affiliation":[{"name":"Ankara University, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"442","DOI":"10.1002\/jcu.10087","article-title":"Gray-scale and color Doppler sonographic findings in a case of subacute granulomatous thyroiditis mimicking thyroid carcinoma","volume":"30","author":"Zacharia TT","year":"2002","journal-title":"J Clin Ultrasound"},{"key":"ref2","first-page":"1047","article-title":"Thyroiditis: differential diagnosis and management","volume":"61","author":"Slatosky J","year":"2000","journal-title":"Am Fam Physician"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"435","DOI":"10.1530\/acta.0.1170435","article-title":"The sonographical and functional sequelae of de Quervain\u2019s subacute thyroiditis: long-term follow-up","volume":"117","author":"Benker G","year":"1988","journal-title":"Acta Endocrinol"},{"key":"ref4","first-page":"143","article-title":"CT and MR imaging findings associated with subacute thyroiditis","volume":"24","author":"Jhaveri K","year":"2003","journal-title":"Am J Neuroradiol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1002\/jcu.1870180106","article-title":"Sonography of subacute thyroiditis: changes in the findings during the course of the disease","volume":"18","author":"Tokuda Y","year":"1990","journal-title":"J Clin Ultrasound"},{"issue":"3","key":"ref6","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1136\/jcp.16.3.189","article-title":"De Quervain\u2019s subacute granulomatous thyroiditis: histological identification and incidence","volume":"16","author":"Meachim G","year":"1963","journal-title":"J Clin Pathol"},{"issue":"4","key":"ref7","doi-asserted-by":"crossref","first-page":"500","DOI":"10.1111\/j.1699-0463.1998.tb01378.x","article-title":"Evaluation of infectious etiology in subacute thyroiditis lack of association with coxsackievirus infec-tion","volume":"106","author":"Luotola K","year":"1998","journal-title":"APMIS"},{"issue":"5","key":"ref8","doi-asserted-by":"crossref","first-page":"2100","DOI":"10.1210\/jc.2002-021799","article-title":"Clinical features and outcome of subacute thyroiditis in an incidence cohort: Olmsted County, Minnesota, study","volume":"88","author":"Fatourechi V","year":"2003","journal-title":"J Clin Endocrinol Metab"},{"issue":"1","key":"ref9","article-title":"Subacute thyroiditis with coexisting papillary carcinoma diagnosed by immediately repeat fine needle aspiration: a case report","volume":"7","author":"Choia YS","year":"2013","journal-title":"J Med Case Rep"},{"issue":"3","key":"ref10","first-page":"263","article-title":"Papillary carcinoma with subacute thyroiditis.
