Struma Ovarii with Later Metastatic Thyroid-type Carcinoma

Year: 2024

Type: article

Abstract: Struma ovarii is a rare ovarian teratoma composed predominantly of thyroid tissue. We report a patient who underwent left adnexectomy and right ovarian cyst excision in 2014. Histology identified struma ovarii on the left and a dermoid cyst on the right, both reported as benign. Seven years later, a pulmonary biopsy showed metastatic thyroid carcinoma, and right adnexectomy revealed thyroid tissue described as suggestive of secondary thyroid carcinoma. Subsequent thyroidectomy showed no thyroid malignancy. The patient received serial radioiodine treatments, with regression of lesions reported on follow-up imaging. Imaging surveillance and biochemical monitoring continued. This case describes metastatic thyroid-type carcinoma in a patient with a previous diagnosis of struma ovarii. The initial findings do not establish bilateral struma ovarii or the precise timing of malignant transformation.
