The Diagnosis of Normal and Pathologic Pregnancy from Curettings
If for clinical or socioeconomic reasons it becomes necessary to interrupt an early pregnancy, a curettage usually yields so much amnion, immature placenta, and abundant decidual tissue that no difficulties in diagnosis arise. Although these tissues are generally normal, they are of value for us, serving as ideal standards which we need for comparison in evaluating and diagnosing tissues from diseased pregnancies. Histological, cytological and cytogenetic studies of the embryo lie within the province of research workers who concern themselves ordinarily with specific problems, for example, chromosomal abnormalities, inherited deficiencies of cellular enzymes. Then too, study of the embryo in the daily routine of gynecological pathology is seldom required, since a primary injury of the fetus causing abortion almost always reveals itself by failure of the fetal vessels in the placental villi to develop.
