RESUMEN
Struma ovarii is a very rare tumour of the ovary, which is usually benign. It is a solid cystic swelling of the ovary, which is characterised by the presence of histologically detectable thyroid tissue. Confirmatory diagnosis is usually on histopathology after resection of the tumour. It is difficult to identify struma ovarii with radiological investigations alone as it may mimic malignancy. In this case report, we present the case of a 48-year-old woman who had a total abdominal hysterectomy for an incidental finding of right adnexal mass on ultrasound scan following a 10-day history of loose stools and pain in the abdomen. It was ultimately found to be a follicular variant of papillary carcinoma in struma ovarii after a pathological examination.
RESUMEN
Struma ovary is a monodermal ovarian teratoma which contains mature thyroid tissue. We present an unusual case of papillary carcinoma arising in struma ovarii. A 52 year old post menopausal lady presented with a large right adnexal mass preoperatively diagnosed as a dermoid cyst. She underwent staging laparotomy and the histopatholgy report showed follicular variant of papillary carcinoma thyroid arising in a mature teratoma. She subsequently underwent total thyroidectomy to enable follow up with serum thyroglobulin and iodine scan. On follow up there is no evidence of disease recurrence.
