We report a rare case of malignant melanoma arising in a cystic teratoma of the ovary occurring in a 60-year-old woman who died in four months despite the combined treatment administrated (surgery and chemotherapy). Diagnosis of ovarian melanoma was confirmed by immunohistochemical positivity to S-100 protein and HMB 45. There was no evidence of extra-ovarian primary melanoma on clinical examination; therefore the diagnosis was primary ovarian melanoma. Melanoma metastases were detected on the uterus, the right ovary, the omentum and in one of the three excised left external iliac lymph nodes. A review of the literature is analyzed and discussed.

From January 1992 to December 1998, 219 women (aged between 30 and 81 yrs; average 55 years) affected by breast cancer were treated. These women in addition to the usual adjuvant therapy, were treated with TAM 20 mg/day, for a period between 24 and 72 months (average 40). In this group there were 84 postmenopausal and 31 premenopausal women. In 8 fertile patients ovarian activity was suppressed with GnRh analogue therapy and one patient underwent attinic castration. Before performing TAM therapy, a hysteroscopic exam was done and patients were followed-up with an annual check-up. None had any endometrial side-effects after the first check-up. After two years, 31 women (26.9%) complained of endometrial alterations (hyperplasia, polyps and endometrial cancer). One women only after 6 years of follow-up, had metrorrhagia; an endometrial adenocarcinoma was found. We would like to point out the necessity of monitoring these patients with an annual check-up (transvaginal sonography and/or hysteroscopy).

From January 1996 to December 1998, 33 patients with endometrial carcinoma were preoperatively examined in our department; 30 women underwent transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI), and 3 only TVUS. Diagnosis was obtained by histopathological examination of the tissue removed by hysteroscopically controlled biopsy or by curettage of the uterine cavity. TVUS and MRI were performed a few days before surgery. After surgery the uterus was histopathologically examined by a pathologist in order to evaluate the depth of myometrial invasion. The results were compared with TVUS and MRI data to determine sensibility and specificity, positive predictive value (PPV) and negative predictive value (NPV) of the two methods. According to the results of the present study we conclude that: TVUS is a low cost, easily performed and reliable method in a high percentage of cases if carried out by a skilled ecographist. MRI, is more expensive and has a lower specificity and sensibility index; it is a valid method if the cervical canal is involved and/or myometrial invasion is > 50% (M2) and if lymphatic invasion has to be investigated.
