Papillary Carcinoma in Mature Teratoma of Struma Ovarii

A Case of Papillary Thyroid Carcinoma in Struma Ovarii and Review of the Literature

Malignancy in struma ovarii is a rare form of ovarian germ cell tumour. Because of its rarity, the diagnosis and management of the tumour have not been clearly defined. We present a case of 67- year-old female with papillary carcinoma arising in struma ovarii and review the literature on malignancy in struma ovarii cases, focusing on management of these cases.

An unusual variant of malignant struma ovarii.

Struma ovarii is a highly specialised form of mature ovarian teratoma. When thyroid tissue constitutes 50% or more of the ovarian neoplasm, the tumour is termed struma ovarii. Malignant struma ovarii is rare and makes up 0.1-0.3% of all ovarian teratomas [2]. We describe a case of follicular variant of papillary carcinoma arising from struma ovarii with elevated CA-125 and pseudo-Meig syndrome.

Poorly Differentiated Thyroid Carcinoma Arising in Struma Ovarii

Struma ovarii is an uncommon type of ovarian mature teratoma with a predominant thyroid component. The morphological spectrum of the thyroid tissue ranges from that of normal thyroid to proliferative adenoma-like lesions and thyroid-type carcinomas (malignant transformation). The histologic features of ovarian strumal lesions sometimes cause diagnostic problems due to the confusion with other t...

Follicular Variant of Papillary Thyroid Carcinoma Arising in a Mature Cystic Teratoma of the Ovary

Mature cystic teratomas form approximately 20% of all ovarian tumours. Of these, approximately 15% include benign thyroid tissue. When thyroid tissue comprises more than 50% of the ovarian teratoma, it is termed ‘‘struma ovarii’’. The exact incidence of malignancy in struma ovarii is hard to evaluate, because of its uncommon nature. The aim of this study is to report a rare case of follicular v...
