Primary Malignant Neoplasm of Ectopic Thyroid Tissue: A Rare Pathology

Xavier Garnica*, Angel Borges and Jose Felix Vivas

The presence of thyroid ectopic tissue arises from an alteration in the embryological development of said gland, and may have aberrant locations throughout the human economy. The possibility of developing cancer in that tissue is highly infrequent, however, it is described in the literature. We present the case of a female patient who debuted with respiratory symptoms in relation to an occupying lesion in the middle mediastinum and the presence of cervical adenomegaly, from which a biopsy was taken and it was positive for metastatic papillary carcinoma of the thyroid, however, in preoperative studies the thyroid was found without alterations; then he presented a tumor in the sacral region whose histology is consistent with that mentioned above, which is why a total thyroidectomy was planned, the surgical specimen being negative for malignancy. In the presence of an unrespectable papillary carcinoma of ectopic thyroid tissue located in the mediastinum, the patient is referred to nuclear medicine to begin treatment with radioactive iodine and subsequently evaluate response.
