ABSTRACT It is difficult to explain ectopic thyroid beneath the diaphragm because during the development the thyroid descends from the tongue to the anterior of the trachea. A few cases of ectopic lesions have been reported in the literature for abdominal organs including the adrenal glands, but the mechanism by which the thyroid components migrate into the abdomen has been poorly understood.
A 54-year-old woman was diagnosed as having an adrenal mass. Laparoscopic adrenalectomy was carried out. Microscopically, the mass was composed of normal adrenal and ectopic thyroid tissues.
We herein describe the fourth case reported of ectopic thyroid in the adrenal gland.

    • "Ectopic thyroid tissue in other locations is rare. There are case descriptions of thyroid tissue identified in diverse locations such as the axilla [6], trachea [7] [8] [9] [10], adrenal [11], small intestine [12], and porta hepatis [13]. The most frequent noncervical location for ectopic thyroid tissue is the thoracic cavity [14] [15] [16] [17] [18]. "

    ABSTRACT: An 80-year-old female presented with an incidental finding of a retrosternal mass on magnetic resonance imaging. Ultrasound demonstrated a mediastinal lesion adjacent to but separate from the inferior pole of the right thyroid lobe. Fine needle aspiration cytology demonstrated colloid and follicular cells. At surgery, the right thyroid lobe was found to be normal. A discrete 5 cm nodule was found in the anterior mediastinum separate from the thyroid and just anterior and to the right of the trachea and thymus. The nodule had a vascular pedicle arising from the mediastinum. The differential diagnosis included metastatic thyroid carcinoma. Histology was consistent with a benign ectopic sequestered thyroid nodule. Extensive investigations demonstrated no sign of a thyroid malignancy.

    ABSTRACT: Ectopic thyroid tissue is a rare abnormality that mainly occurs in the midline of the neck but also in other unusual locations. Because fine needle aspiration biopsy (FNAB) is a widely used procedure for evaluating head and neck and other palpable masses, sampling of these lesions may be encountered. A 66-year-old woman presented with left lateral chest wall mass during follow-up for chronic obstructive pulmonary disease, hypertension and diabetes mellitus. Initial evaluation by FNAB suggested ectopic thyroid tissue, which was confirmed later by tissue biopsy and immunostains. This is the first reported case of ectopic thyroid tissue in the lateral chest wall area. Awareness of this abnormality and the possibility of ectopic thyroid tissue in erratic locations will help cytopathologists make the correct interpretation on FNAB sampling.

    ABSTRACT: Background Ectopic thyroid tissue is a rare abnormality that mainly occurs in the midline of the neck but also in other unusual locations. Because fine needle aspiration biopsy (FNAB) is a widely used procedure for evaluating bead and neck and other palpable masses, sampling of these lesions may be encountered. Case A 66-year-old woman presented with left lateral chest wall mass during follow-up fir chronic obstructive pulmonary disease, hypertension and diabetes mellitus. Initial evaluation by FNAB si suggested ectopic thyroid tissue, which was confirmed later by tissue biopsy and immunostains. This is the first reported case of ectopic thyroid tissue in the lateral chest wall area. Conclusion Awareness of this abnormality and the possibility of ectopic thyroid tissue in erratic locations will help cytopathologists make the correct interpretation m FNAB sampling.
