Abstract |
Struma ovarii is a rare and highly specialized form of ovarian teratoma; in which thyroid tissue is
the exclusive element (>50%). It comprises about 2% of all teratomas; and the majority of struma
ovarii is benign tumor. But malignant struma ovarii; which showed malignant cell change arising in
the benign struma ovarii; rarely reported. Here; we report an incidentally detected case of
papillary thyroid carcinoma arising in the struma ovarii due to contralateral ovarian torsion in a
80-year old female. |
