Abstract
Background
Struma Ovarii are mature teratomas. In rare circumstances thyroid tissue is found as part of the histopathological makeup. Malignant transformation may occur in 1–2% of these rare cases.
Aim
To report a rare case of malignant thyroid carcinoma within a struma ovarii.
Result
A 22-year-old lady presented with a right pelvic mass. A right-sided laparoscopic salpingo-oophrectomy was performed which revealed a malignant struma ovarii neoplasm. A total thyroidectomy was performed with adjuvant I131 therapy.
Conclusion
This is a rare tumour which necessitates surgical extirpation and removal of a normal thyroid gland to facilitate thyroglobulin monitoring.
