Co-existence of Nodular Hyperplasia and Papillary Carcinoma Thyroid in a Case of Struma Ovarii: A Rare Occurrence
Abstract
Struma ovarii is a monodermal ovarian teratoma. This is an ovarian germ cell tumour with more than 50% ovarian tissue. It is a rare tumour, accounting for only 3-5% of all ovarian teratomas. Malignant transformation occurs very rarely, only in about 0.3% cases. The authors report a case of struma ovarii with a malignant transformation to papillary carcinoma thyroid. Not much information is present in the literature about this rare entity. Due to the rarity of this condition, there is a lack of uniformity of histological criteria of malignancy and its management is not universally accepted by physicians. Here, the authors present a rare case of struma ovarii with malignant transformation to papillary carcinoma thyroid. A 62-year-old female presented with a left ovarian mass. On histopathological examination of the surgical specimen of hysterectomy it was found that the ovary had a neoplastic growth with morphological features of papillary carcinoma thyroid. The final diagnosis was struma ovarii with papillary thyroid carcinoma. Postoperative period was uneventful for the patient. However, follow-up was not done.
