[Ovarian mature teratoma. Clinico-pathological study of 112 cases and review of the literature].

A retrospective, descriptive study of 112 patients diagnosed and treated of mature ovarian teratoma, between January 1995 and September 2001, at Reina Sofía University Hospital, was carried out. The patient's mean age is 36.2 years old (SD = 13.8). The most frequently symptom was abdominal pain (50.9%) though a high percentage of the cases (41.1%) the patients were asymptomatic. The mean size of the tumor was 76.2 mm (SD = 35.8) and 9.8% were bilateral. The most used diagnostic procedure was ultrasound with a right diagnostic of 47.6%, though 81.3% of the cases a surgery was performed, with a preview diagnostic of ovarian tumor and the 53.8% with the right diagnostic of benign teratoma. 18.7% of the tumors was found in a laparotomy for other cause. From the 123 tumors, 96% were benign ovarian cyst, 1.6% mature solids teratomas and 2.4% struma ovarii. The most frequent surgery was unilateral oophorectomy (54.5%) and 19.6% was total hysterectomy with bilateral oophorectomy, with the mean age of this last ones of 54.8 years old (SD = 12.0). The preservation of the ovarian function was in 75% of the patients. We will analyze our results and compare with the bibliography.
