Needle biopsy showed anaplasti c malignant cells. Pathologic evaluation after thyroidectomy showed ch oriocarcinoma in the thyroid gland and the patient subsequently underw ent combined chemotherapy and radiotherapy with satisfactory response. This is only the third reported case of metastatic choriocarcinoma in the thyroid gland and emphasizes this rare clinical presentation of c horiocarcinoma.
