1/3. Metastatic thyroid carcinoma in the presence of struma ovarii.A 27-year-old woman presented with metastatic follicular carcinoma of thyroid cell type. Assessment was complicated by recent surgery for "benign" struma ovarii. She underwent total thyroidectomy which failed to show a neoplasm, leaving the struma ovarii as the likely source of the metastasis.- - - - - - - - - - ranking = 1keywords = struma ovarii, struma, ovarii (Clic here for more details about this article) |
2/3. Oxyphilic follicular tumor arising in struma ovarii.The present report describes a case of a proliferative lesion developed in a struma ovarii of a 26-year-old woman who presented with asymptomatic bilateral mature ovarian teratomas. The tumor immunohistochemically and ultrastructurally proved to be an oxyphilic follicular thyroid tumor. Although it showed some histologic features which could raise a suspicion of malignancy (solid, trabecular pattern and nuclear pleomorphism), no unequivocable signs of aggressive behaviour (high mitotic activity and vascular invasion) were evidence. The patients was alive and well 1 year after a bilateral subtotal ovariectomy.- - - - - - - - - - ranking = 0.83333333333333keywords = struma ovarii, struma, ovarii (Clic here for more details about this article) |
3/3. Ovarian metastasis from thyroid carcinoma 12 years after partial thyroidectomy mimicking struma ovarii: report of a case.A 29-year-old woman experienced abdominal swelling 12 years after undergoing partial thyroidectomy for follicular carcinoma of the thyroid with vascular invasion and 6 months after a right cerebral tumor that had caused hemiplegia had been excised. laparotomy disclosed a solid and cystic right ovarian tumor, 17 cm in greatest dimension, and a 12-cm tumor of the right adrenal gland. Microscopic examination showed a malignant tumor of the thyroid follicular type with frequent mitotic figures; other teratomatous elements were absent. Because of the interval since the thyroid cancer, the diagnosis of a malignant struma ovarii was initially considered. The patient rapidly developed widespread metastatic disease and died, supporting the interpretation that the ovarian tumor was a metastasis from the thyroid neoplasm. This case illustrates that when other teratomatous elements are not identified, the diagnosis of malignant struma ovarii should be made only when the possibility of spread from a prior thyroid neoplasm, possibly one treated many years previously, has been excluded.- - - - - - - - - - ranking = 1keywords = struma ovarii, struma, ovarii (Clic here for more details about this article) |
