Follicular carcinoma in a lingual thyroid

Lingual Thyroid in Children

“…The majority of carcinomas observed in the lingual thyroid are reported to be follicular. [2] Lingual thyroid is the most frequent ectopic location of the thyroid gland, although its prevalence varies between 1: 100 000 and 1 : 300 000 and its clinical incidence is reported to range from 1 : 4000 to 1 : 10000.…”

Unusual presentations of thyroid malignancies — a case series

“…Obstructive symptoms include foreign body sensation, dysphagia, dysphonia and dyspnea. Both follicular and papillary carcinomas in lingual thyroid have been reported [7,8]. These studies underline the fact that malignancy must be excluded in all the cases of lingual thyroid since the presence of malignancy completely changes the management of this rare condition irrespective of the presence or absence of a functioning thyroid gland.…”

“…Malignancies arising from ectopic thyroid tissue found along thyroglossal tract, lateral cervical regions, branchial cyst, trachea and myocardium have been reported in the literature [3,6,7,9,10,16]. Four such unusual case scenarios are presented.…”

Differentiated thyroid carcinoma in lingual thyroid

“…Follicular carcinoma is usually reported as being the predominating histopathology in LTC [10,[20][21][22][23][24]. However, among the 51 anecdotal cases of LTC described so far (Table 1), histological findings range from equivocal descriptions of malignancies [6,7,[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], ultimately dating back from the beginning of the last century to early 70s, to detailed histopathological diagnoses of differentiated thyroid carcinoma [20][21][22][23]. Tightening our focus on LTC diagnosed following the release of standardized criteria of histological typing [66], the available data show that papillary thyroid carcinoma (PTC) is actually the prevailing type of LTC, accounting for about 65 % of the reported cases.…”
