LOW-MALIGNANT POTENTIAL EPITHELIAL TUMORS OF THE OVARY - A CLINICOPATHOLOGICAL STUDY

Low-malignant potential (LMP) epithelial tumors of the ovary are a gro up which occupy on intermediate position between the benign and those of the frankly malignant ovarian neoplasms. The actual incidence, pres ent age and treatment are still being discussed. During the period 199 1-1996, from the 650 ovarian tumors which were diagnosed and treated i n our institution, 401 were epithelial tumors. The LMP serous epitheli al tumors consisted of 4.36% of all serous tumors while LMP mucinous t umors were 9.70% of all mucinous tumors. The LMP serous tumors had an 8 cm diameter on average, 83% were unilocular and 76.5% unilateral. Th e LMP mucinous tumors had a 17 cm diameter on average, 95% were multil oculur and 95% unilateral. The mean age at diagnosis was 39 years for LMP serous tumors and 48 years for LMP mucinous tumors.
