title: [Struma ovarii: a variety of monodermic teratoma of the ovary. Report of 8 cases].
abstract: Inside the germinal neoplasms of the ovary, the monodermic or specializad teratomas constitute a not very frequent variety. The struma ovarii represents 2.7% as the form more common of this teratomas type, constituted by thyroid tissue. Struma ovarii can associate to other tumors of the ovary of germinal type as dermoid cyst, carcinoid tumor or non germinal tumors as type as dermoid cyst, carcinoid tumor or non germinal tumors as mucinous or serous cyst or Brenner tumor. Most of the struma ovarii are benign and 5-10% only are malignant, of these group 40% has only associated to extraovaric dissemination. The objective of the present work is to analyze the clinical, epidemical and biological characteristics of the struma ovarii. Eight cases of struma ovarii are presented, that occupy 4% inside the ovary tumors diagnosed and treated in our hospital. The clinical charac-teristics of these tumors were: age average 45.5 tears, pelvic mass accompanied by distension and abdominal pain. They were managed as anyone ovary tumor, in not any case the diagnosis it was suspected, 4 were presented of the left side and 4 in the right, the weight average was 726.2 g. Only in 4 cases was carried out the transoperative diagnosis and the eight cases confirmed in the postoperative. In not any case hyperthyroid symptoms, neither morphological criteria of malignancy were presented. Only in two cases the struma ovarii was reported as pure, in the 6 remaining it is accompanied with another type of ovarian neoplasm.
