Papillary Thyroid Carcinoma Within Mature Teratoma Ovarian: A Rare Case Report

Abstract

Papillary thyroid carcinoma is a rare germ cell tumor. We report a case of a 50-year-old woman who presented with an enlarged abdomen since a year ago. From the physical and ultrasound examinations, the patient was then diagnosed with a suspected malignant ovarian cyst. Postoperative histopathology results showed papillary thyroid carcinoma arising within mature cystic teratoma. Then, the patient was examined for thyroid ultrasonography, which revealed a benign nodule on the left thyroid. This result was supported by normal results of thyroid function and anti-thyroglobulin antibody tests, which was a sign of benign condition. The anatomical pathologists then concluded that the primary was of ovarian origin. Differentiating the primary source of papillary thyroid carcinoma, either from the ovary or thyroid, is essential to plan further proper management. Here, the report aims to describe how to diagnose papillary thyroid carcinoma arising within mature teratoma of the ovary and its management strategy.
