Background: Ovarian strumal carcinoid is a germ cell tumour characterised by a mixture of thyroid tissue and carcinoid. Ovarian struma is a very rare occurrence with 0.3-1% incidence of all ovarian tumours and 3% of mature teratomas. Primary carcinoid ovarian tumours are still uncommon as a part of mature teratoma or mucinous cystadenoma. There are four major variants of a carcinoid tumour: insular, trabecular, strumal and mucinous. A strumal carcinoid is an unusual form of ovarian teratoma composed of an intimate admixture of thyroid/carcinoid tissues.
Case Report: This is a case report of a 59-year old woman with a 5-year clinical history of perimenopausal uterine bleeding and three explorative curettages. Gynaecological and ultrasound examinations revealed ovarian enlargement with a diameter of 50 mm with hypoechoic zones suspected of benign teratoma. The diagnostic test such as Ca-125, AFP, free-T4 and TSH was in normal range. A smooth, solid right ovarian 50 an mm-size tumour, as well as small amount of fluid in the Douglas pouch, was found during the total abdominal hysterectomy, bilateral salpingo-oophorectomy and staging biopsy. The histopathology revealed teratoma with strumal carcinoid tumour IA stage according to AJCC 2010 of the right ovary and negative cytopathology of the fluid from the Douglas pouch. On the postoperative 2-year control, the patient was tumour free, and Ca-125, free-T4 and TSH were in normal range.
Conclusion: We would like to point out those specific diagnostic tools, such as ultrasound and Ca-125 have low specificity and sensitivity in detection of this rare ovarian malignancy.

Ovarian carcinoid is a rare well-differentiated neuroendocrine tumor resembling those arising in the gastrointestinal tract. We present a case of ovarian carcinoid with magnetic resonance imaging (MRI) findings. A 50-year-old woman with genital bleeding and severe constipation was referred to our hospital.

Very few cases of stromal carcinoid have been reported in the literature in women of childbearing age, particularly during pregnancy.

Struma ovarii is a well-known ovarian teratoma made up of benign thyroid tissue. These lesions demonstrate variable, normal architecture and normal thyroid immunohistochemical staining with positivity for TTF1, PAX8, and thyroglobulin. Though most are benign, some of these lesions can also present with a malignant component.
