Definition / General
● Spontaneously exfoliated endometrial cells are often seen during the first 12 days of the menstrual cycle
● May also be due to hormone replacement therapy (Obstet Gynecol 2002;100:445) or tamoxifen
● Endocervical sampling devices may inadvertently sample the lower uterine segment or endometrium
● Variable association of benign endometrial cells at pap smear with endometrial pathology in postmenopausal women (yes: Am J Clin Path 2005;123:571, Diagn Cytopathol 2001;45:153), (no association: Cancer 2005;105:207, Diagn Cytopathol 2001;25:235)
● Most associated carcinomas are in women age 45+ years (Am J Clin Pathol 2005;124:834)
● Exfoliated endometrial cells often present as small cells arranged in balls with scant cytoplasm, dark nuclei and nuclear molding and fragmentation
● Abraded endometrial cells may present as large and small tissue fragments with glands and stromal cells
● Resemble histiocytes
● Easier to identify if in clusters
