title: Synchronous ovarian and endometrial carcinoma: a strong link to endometriosis?
abstract: OBJECTIVE
  To further study the clinicopathological features of synchronous ovarian and endometrial carcinomas.
  
  
  METHODS
  We retrospectively studied all cases of synchronous ovarian and endometrial carcinomas diagnosed in our laboratory over the last 15-year period. The pathological findings were correlated with the clinical records of the patients.
  
  
  RESULTS
  Seven cases of synchronous primary ovarian and endometrial carcinomas were retrieved. The most common presenting symptom was abnormal vaginal bleeding (5 cases, 71.4%). Five patients (71.4%) were postmenopausal and two (28.6%) were nulliparous. All seven patients had Stage I ovarian and endometrial carcinomas of endometrioid histology. Moreover, in all seven ovarian carcinomas endometriosis foci were observed, while atypical endometriosis was found in four of them. With the exception of one patient, who received adjuvant postoperative radiation, all remaining patients were treated with surgery alone. All patients were alive and free of disease at completion of the study.
  
  
  CONCLUSIONS
  The correct classification of synchronous primary ovarian and endometrial carcinomas is often problematic because of the frequent confusion with their metastatic counterparts. Although the exact etiology remains unclear, endometriosis seems to be a major risk factor for their development.
