A Case of Trophoblastic Tumor Associated with Papillary Thyroid Cancer / 대한내과학회지

ABSTRACT

Thyroid cancer is one of the most common endocrine malignancies. It is known that thyroid cancer can develop during reproductive periods, possibly due to the effects of sex hormones and growth factors such human chorionic gonadotrophin (HCG). Some data suggest that elevated HCG levels during pregnancy or gestational trophoblastic disease can stimulate thyroid cellular proliferation and promote cancer formation; however, a case of papillary thyroid cancer accompanied by a gestational trophoblastic tumor has not been reported. Here, we report the case of a 44-year-old woman with papillary thyroid cancer during treatment for a gestational trophoblastic tumor.
