“…The most common presentation is a basicervical anterior mass mimicking a thyroid nodule [ 8 ]. In a few cases the cyst has been discovered by incidental thyroid imaging, chronic thyroiditis or hyperparathyroidism [ 9 , 10 ]. Our patient presented with a descending thyroid nodule with hypothyroidism.…”

Thyroglossal duct cyst (TDC) commonly occurs in the neck just below the hyoid bone. Uncommon sites of TDC have been documented, and of these, an intra-thyroid location is very rare. We report such a rare intrathyroid TDC (ITTDC) initially identified by ultrasound examination as an incidental thyroid imaging reporting and data system (TI-RADS) three lesion in the left thyroid lobe of a 59-year-old male patient with primary hyperparathyroidism due to a parathyroid adenoma. The preoperative ultrasound-guided fineneedle aspiration biopsy (US-FNAB) cytology of the thyroid lesion was interpreted as Bethesda III (atypia of undetermined significance or follicular lesion of undetermined significance). A left hemithyroidectomy and left superior parathyroidectomy were performed. The postoperative histology revealed the thyroid lesion to be an ITTDC. An incidental papillary thyroid microcarcinoma was also histologically revealed. The 2.5-year postoperative follow-up was uneventful. Based on literature searches, the clinical features, fine-needle aspiration biopsy (FNAB) cytology, histology, differential diagnosis, treatment, and follow-up of ITTDC were reviewed and discussed. A proposal to categorize ITTDC into two anatomical location subtypes is made. The liability of ITTDC to be misinterpreted on FNAB cytology due to rarity and lack of morphological specificity is emphasized.

Background In cases of papillary thyroid carcinoma (PTC), lymph nodes are a typical site of metastasis. Extrathyroidal tissue involvement in differentiated thyroid carcinoma causes the disease to progress and affects the patients’ treatment options. Papillary thyroid carcinoma (PTC) is the common type in differentiated thyroid carcinoma (DTC), the other type is follicular thyroid carcinoma (FTC). Ectopic sites, such as intrathyroidal lymph node invasion in classical papillary thyroid malignancy, are extremely uncommon. It can be difficult to detect an intrathyroidal lymph node (ITLN) during a histopathological test, but it is important to do so since it affects the stage of the disease and subsequent treatment. Case presentation We present the case of a 63-year-old woman who presented with multinodular goitre and underwent total thyroidectomy. She was diagnosed with aberrant intrathyroidal lymph node metastases during pathological testing, resulting in an upgrade in treatment. Owing to the exceptionally unusual ectopic position of lymph node metastasis, in this case, there is a risk of diagnostic and therapeutic misinterpretation. This patient was treated with high-dose radioactive iodine in view of lymph node metastases. Conclusions Identification of ITLN by imaging characteristics is sometimes difficult, being often an intraoperative discovery and histopathological correlation that lead to upstage the disease and alter the final management.
