[Discrepancies in the histological diagnosis of hyperplastic states and cancerous pathology of the endometrium].

Two hundred and seventy-two scrapings of the endometrium and histologic sections of seven removed uteri obtained from 30 hospitals of Leningrad were reviewed at the pathology departments of the Institute and Oncologic Dispensary. Disagreement in diagnostic conclusions (malignancy, border-line condition, other pathology or normal tissue) was registered in 51%. Disagreement ranged from 15% (hydatidiform mole) to 71% (atypical hyperplasia of the endometrium). The extent of disagreement between staff members of the two medical establishments and that between the said specialists and other consultants was of the same order.
