“…They have reported the presence of hypoechogenic regions during the active phase, and their regression and disapperance when the clinical symptoms ameliorated. They have shown in 3 patients that hypoechogenic regions reoccured with the recurrence of the disease (12). In our case, there was also significant decrease in hypoechogenic regions following therapy.…”

Subacute thyroiditis (SAT) association with thyroid carcinoma has been rarely reported in the literature. 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.

“…Ultrasonography provides important clues for diagnosis of SAT however hypoechogenic regions that are typical ultrasonographic findings of subacute thyroiditis are not specific to this disease (12). Hypoechogenity, nodule shape, tumor magrin, hypoechoic rims are important factors in evaluating nodule for thyroid carci-noma (13).…”

“…7 Improvement in SAT on sonography is fairly parallel to that on cytology even though there is a lag in the perception of improvement in the latter. 7 Ultrasound-guided FNAB is a convenient method of obtaining sufficient and representative specimens from patients with SAT. 7 Although there are reports of ultrastructure of SAT studied by transmission electron microscopy (TEM) on specimens from operations, 8,9,11 as far as we know, there are no reports on 3-dimensional (3-D) cytomorphology of SAT.…”

Subacute thyroiditis (SAT) is usually diagnosed clinically without the need for fine-needle aspiration. The cytologic literature on this condition is therefore rare. We report on 14 cases of SAT presenting with thyroid nodules. The majority of patients were women with a mean age of 46 yr. All had pain/tenderness in the thyroid area accompanied by fever or an elevated ESR. The salient cytologic features included cellular smears; multinucleated giant cells in 100% of cases, some ingesting colloid or neutrophils; fibrous fragments with enmeshed inflammatory cells were a constant feature; follicular cells were scant to absent in most cases. Granulomas were rare. Colloid, when present was thick, with central cracks and frayed edges. One case was suspicious for malignancy. We conclude that the cytologic features of SAT are predictable, particularly, in the appropriate clinical setting. FNA is also helpful in ruling out concomitant neoplastic conditions.
