title: A follicular adenoma arising from the thyroid tissue of a benign cystic teratoma during pregnancy--lightmicroscopical, ultrastructural and endocrinological studies.
abstract: A rare case of follicular adenoma arising from the thyroid tissue of a benign cystic teratoma of the left ovary was described in a 28-year-old, 13 weeks pregnant woman. Histologically, the tumor showed pleomorphic adenomatous patterns; embryonal type, fetal type, simple type and oxyphil type. The final diagnosis of follicular adenoma was established by ultrastructural, immunohistological and endocrinological studies. The patient was successfully operated, delivered of a normal full term male infant and is now under a follow-up study.
