Clinicopathologic implications and diagnosis of nongranulomatous nonspecific endometritis.

The analysis of 600 subsequent endometrial biopsies from urban gynecologic outpatient clinics was carried out with special regard to nongranulomatous and nonspecific endometritis. The total incidence of inflammatory changes reached 10.8%; after excluding all postabortion and puerperal endometria 9.4% of the curettings showed endometritis. The relative occurrence of acute, subacute, and chronic disease was respectively 6.2, 30.8, and 63.0%. The etiologic factor remained obscure in 64.7% of all the cases. The influence of inflammatory changes on the hormonally induced modifications of the endometrium are discussed.
