Abstract |
35-year-old female presented with recurrent spinal mass that was resected. Pathologic examination revealed mature teratoma consisting of thyroid follicles, fibroadipose tissue, and mature bony particles. And in this teratoma, focal area of papillary thyroid carcinoma component arising from the normal thyroid follicles were observed. This finding was clearly distinguished from metastasis from thyroid or from other sites. The patients underwent evaluation of thyroid gland, and there was a 1.2¡¿1.1¡¿2 cm sized nodule. It was well-margined, round, mixed and hyperechoic by sonographic evaluation, and its aspirates contained benign-looking follicular cells only. The patient refused further evaluation or treatment about thyroid cancer, and was discharged. To date, there are only one case of thyroid carcinoma arising from a sacrococcygeal mass containing thyroid tissue components alone (Thyroid 2004:14:548-552). We believe that this patient is a very rare case of thyroid cancer primarily arising from teratoma due to malignant transformation of its thyroid tissue component.(Korean J Med 70:455-461, 2006)
