Another 1 case was misdiagnosed film reading errors , as in this case theca cell tumor cells rich in tightly packed cells, plasma fewer misdiagnosed as granular cell components. By the time the frozen section and the restrictions of objective conditions and other factors , generally can not do a lot of frozen section biopsy , therefore, highly suspicious cases, frozen section should be appropriate to expand the scope drawn in order to reduce misdiagnosis.

Reported population of 32,000 Massachusetts General Hospital in June reported 140 cases of borderline ovarian tumors found frozen section and paraffin section was only 6O% ( misdiagnosis rate of up to 4O).
