Estruma ovarii maligno / Malignant struma ovarii

The Malignant Struma ovarii (SO) is a thyroid carcinoma generated in a mature teratoma, constitutes 0.8-3percent of ovarian tumors. Then, two cases will be reviewed. Case 1: 46 year old woman with no known morbid consulted for right iliac fossa pain requiring exploratory laparotomy with findings of an ovarian tumor, the biopsy reported mature ovarian teratoma SO type microfocus papillary thyroid carcinoma. Case 2: 59 year old female with a history of dyslipidemia and knee osteoarthritis in controls in gynecology since 2010 on the right adnexal mass of cystic type of 5x3 cm. The study showed only free fluid dissemination ovarian, oofectomía bilateral was performed and biopsy showed minimally invasive follicular carcinoma (2.8 cm) developed by SO, serosa without invasion of the ovary. Is derived of endocrinology and the study showed: thyroid stimulating hormone (TSH) 3.3 uIU/ ml; Peroxidase antibody (anti-TPO) and thyroglobulin antibody (antiTG) negative. Ultrasonography exhibited thyroid nodule of 0.8 x 0.6 cm, hipovascularizado with normal thyroid cintigraphy and cytology negative for neoplastic cells in fine needle aspiration (FNA). Discussion: It’s a rare condition, which requires a multidisciplinary approach to treatment...

Struma ovarii con un foco de micro-carcinoma papilar variante folicular de tiroides: reporte de caso y revisión de la literatura / Struma ovarii with follicular variant of papillary thyroid carcinoma: report of one case

Struma ovarii is an ovarian teratoma composed mainly of thyroid tissue, which can occasionally develop a malignant thyroid tumor. We report a 61 years old female consulting for a metrorrhagia in whom an ovarian cyst was discovered. The patient was subjected to a hysterectomy and bilateral oophorectomy. The pathological study of the surgical piece revealed a focus of papillary thyroid carcinoma, follicular variety in a right struma ovarii. Three months after surgery, an abdominal CAT scan did not show any abnormality.

Hipotiroidismo primario luego de la resección de un Struma ovarii / Primary hyperthyroidism after excision of a Struma ovarii

Struma ovarii is a teratoma composed of thyroid tissue and can be a rare cause of hyperthyroidism. We report a 35 years old woman with a left ovarian mass whose pathology revealed a Struma ovarii. This tumor was partially excised initially to avoid fertility problems and after a successful gestation, the tumor was completely removed during a cesarean section. Sixty days after delivery a hypothyroidism was diagnosed. Levothyroxine was started and euthyroidism was achieved.

le goitre ovarien aspects anatomo-cliniques et therapeutiques. A propos de 6 cas

Ovarian goiter or strouma ovarii is an ovarian mature teratome in which thyroidal contingent is the most frequent. We have realised a retrospective study in CMNRT "service A" on a period of fifteen years during which we have studied anatomopathological, surgical and therapeutic aspect s of six cases of ovarian goiter. Clinical picture is not specific and the diagnosis is always histologic. We have remarked one case of malignant ovarian goiter: 1 case/six: this rate is between 5-20% in the literature. Treatment is always surgical, this pathology have a favorable prognosis
