The m.st a.propria.e a.ea.thought to be representa.ive of lesion wa. chosen. The num.er of sections frozen wa. depended on the type a.d size of the tum.r. Seven to eight μm.sections were obta.ned a.d sta.ned with hem.toxylin-eosin. The specim.ns were then fixed in form.lin. Pa.a.fin blocks of the sections were processed in the routine wa. a.d sections were sta.ned with hem.toxylin a.d eosin (H a.d E). The dia.nosis obta.ned by intra.pera.ive frozen section ba.ed on cellula.ity a.d cell m.rphology wa. com.a.ed with fina. histopa.hologica. dia.nosis in term. of dia.nostic sensitivity, to differentia.e between benign a.d m.ligna.t lesions. a.sessm.nt of the overa.l a.cura.y of the intra.pera.ive dia.nosis wa. cla.sified a. concorda.t or discorda.t. Results: There wa. no sta.istica.y significa.t differencre in the studied pa.ients a. rega.d the clinica. da.a. m.croscopic a.d intra.pera.ive picture, while there wa. sta.istica.y significa. a.socia.ion a. rega.d the la.era.ity of the ova.ia. m.sses. The va.idity of frozen section in the dia.nosis of benign tum.ur wa. 100% with 100% a.cura.y, specificity, positive predictive va.ue, nega.ive predictive va.ue, while sensitivity & nega.ive prediction for borderline tum.ur a.d specificity & positive prediction of m.ligna.t tum.ur were 100%, specifecity for borderline tum.urs wa. 95% while the positive predictive va.ue wa. 33.3% with 96% a.cura.y for both m.ligna.t a.d borderline tum.urs.
