“…Due to the absence of thyroid tissue in loco typico, the non-metastatic origin of the carcinoma in our patient is obvious. In addition to the description of this first case of papillary carcinoma in a sublingual ectopic thyroid in the absence of a regular gland we would like to draw the attention to a management problem in this patient, caused by an initial misdiagnosis, which has been de scribed repetitively under similar circumstances [1,3]. After removal of the cervical mass, initially diagnosed as a thyroglossal duct cyst, the clinical features of hypothy roidism emerged although preoperatively thyroid func tion was apparently normal.…”

Ectopic thyroid tissue can be seen anywhere from the foramen caecum to the lower neck. Most frequently it presents as a thyroglossal duct cyst associated with a normal thyroid gland. Less common is total ectopia, which can occur as a lingual thyroid or occasionally in non-lingual locations. Malignant transformation of such ectopic tissue is extremely uncommon. Only 21 cases of lingual thyroid carcinomas have been reported until 1971. We present, to our knowledge, the first case of a papillary carcinoma in a non-lingual ectopic thyroid in the absence of an orthotopic thyroid.

“…Surgical resection is considered in patients who fail medical treatment, in those who are suspicious of malignancy, and in those who have cosmetic problems (6). However, 70-90% of patients have no functioning thyroid tissue besides that found in the ectopic location, so extreme caution must be exercised; removal of the only functioning thyroid tissue will result in permanent hypothyroidism (8, 10). In our case, it would have been better to begin with medical treatment.…”

Adenomatous Hyperplasia Arising from Dual Ectopic Thyroid

Ectopic thyroid tissue is an uncommon embryologic aberration characterized by the presence of thyroid tissue in a site other than its usual pre-tracheal location. Single ectopic thyroid tissue is the most common variant, and the base of the tongue is the most frequent ectopic location. Dual ectopic thyroid is extremely rare, and only eleven cases have been reported in the English literature. Furthermore, adenomatous hyperplasia has never been reported to arise from dual ectopic thyroid. There has been only one reported case of adenomatous hyperplasia arising from a single intratracheal ectopic thyroid. We report a case of adenomatous hyperplasia arising from dual ectopic thyroid tissue that presented as a sublingual mass in a 37-yr-old woman. The diagnosis was made through pathologic examination after surgical resection. We also discuss the diagnosis and treatment of ectopic thyroid, along with a review of the literature.

“…We report a case found above the hyoid bone (Sublingual). It must be differentiated from thyroglossal duct cyst, because it is usually located in the same anatomic position 13 & frequently represents the only source of thyroid tissue, removal of which has definite physiologic as well as possible medicolegal implications. To prevent total thyroid ablation, a thyroid scan or ultrasound examination must be performed in all cases of thyroglossal duct cyst before its removal so as to be certain that a normal thyroid gland is present.…”
