Abstract

Mixed thyroid carcinoma is a term to describe the carcino­ mas composed of papillary­medullary or follicular­ medullary carcinomas and these carcinomas arise from the same thyroid gland and display morphological and im­ munophenotypical features of both origins within the same lesion. A few cases has been reported in the literature and recently there are some molecular studies searching the de­ velopmental mechanisms of these tumors.

Here in, we aimed to present a pregnant case with synchro­ nous medullary and papillary thyroid carcinoma.

In the present case, the most remarkable features of this case was the patient’s being pregnant at the time of the di­ agnosis and the presence of metastatic lymph node on the side of papillary tumor originating from the contralateral medullary carcinoma. The patient went to bilateral total thyroidectomy, central neck dissection of left side and right sided modified radical neck dissection.
