Ectopic Thyroid Tissue in the Adrenal Gland: Report of a Case

We present the case of a 32-year-old woman with ectopic thyroid parenchyma in the adrenal gland. Clinically, postoperative thyroid ultrasound echography and computed tomography scans did not reveal any thyroid tumor. The ectopic tissue was a cyst bordered by mature follicular thyroid structures and was histologically benign, without the molecular alterations associated with malignant tumors of follicular cell derivation (BRAFV600E, N-RAS, H-RAS, K-RAS). Review of the literature reveals that adrenal ectopic thyroid tissue is nearly always cystic and has distinctive pathologic features.
