Incidental papillary thyroid carcinoma in thyroglossal duct cyst case report

Abstract

HighlightsThe differentiated thyroid carcinoma in thyroglossal cyst is a rare entity.The incidence is 1 to 2%.Usually their clinical presentation is indistinguishable from a benign lesion and postoperative definitive diagnosis.The thyroglossal cyst is found in 7% of the population.Papillary carcinomas have favorable prognosis and cervical or distant metastases are rare.

Incidental thyroid carcinomas. A retrospective study

“…In contrast to the advocates of conservative surgery, it should be recalled that in our series, the gland portion most frequently affected by the neoplasm was the posteromedial one located in the proximity of the point where the recurrent nerve enters the larynx and more precisely, in that portion of the gland that is preserved as a residue in case of non-radical thyroid surgery, as well as the pyramidal lobe, in which incidental carcinomas are described (103,104). Supporters of partial thyroidectomy for incidental carcinoma claim that the motivation of their surgical choice, is a possible definitive postoperative hypoparathyroidism or the possibility of surgical lesions of the inferior laryngeal nerve.…”

Ectopic thyroid with benign and malignant findings: A case series

“…Thyroglossal duct carcinoma is often diagnosed incidentally during histopathological examination of a resected cyst [12,13]. It may be due to residual ectopic thyroid tissue in the duct (>90 % cases) or it may arise from the epithelium of the cyst wall [11,12]. CMV-PTC accounts for 0.2 % of all PTCs [14].…”

Thyroglossal Duct Cyst Papillary Carcinoma With Airway Compromise

“…One is the hypothesis of de novo theory basing on the evidence of ectopic thyroid tissue within the cyst and absence of metastatic disease. 4,8,9 The other is the metastatic theory, which suggests that the lesion is metastatic from an occult primary thyroid gland. 10 In our case, calcification within the tumor is localized within the thyroglossal duct cyst that is revealed on the computed tomography scan and it did not extend beyond the cyst, which contains normal epithelial lining, and no malignancy is found in the main thyroid gland.…”
