In the study of the pathologic conditions of the endometrium which are not the results of infection, several are encountered that may be confused with each other or with the normal endometrium or with adenocarcinoma of the body of the uterus. The premenstrual endometrium is the normal form most frequently mistaken for some pathologic state; but occasionally a hypertrophic endometrium with narrow contracted glands, unless care is exercised, may be mistaken for a normal postmenstrual type. Among these noninflammatory hypertrophies are those associated with extra-uterine pregnancy, with ovarian growths and a third group for which we have at present no adequate explanation and which may be divided into two groups, the glandular and the interstitial.
On account of the frequent references that are made to endometritis and hypertrophy of the endometrium associated with uterine fibroids and retrodisplacements, I have included in this paper the results of my investigation of the
