• acute endometritis
  17 July

  Synopsis
  microabscesses
  infiltration
  destruction of glandular epithelium
  NB : neutrophils are common in cycling endometrium
  Etiology
  Limited to post delivery or miscarriage,
  presence of moderate to marked myometrial inflammation is not predictive of post cesarean section endometritis (Am J Clin Pathol 2003;120:217)
  due to retained products of conception or instrumentation

• granulomatous endometritis
  17 July

  Etiology
  uterine sarcoidosis / endometrial sarcoidosis granulomas usually spread to myometrium (in contrast to TB)
  uterine tuberculosis plasma cells and white blood cells may be present due to secondary infection; acid fast bacilli present in tubercles or culture; granulomas tend to accumulate in superficial functional layers of endometrium, so biopsy during late secretory phase

• endometrial intraepithelial carcinoma
  18 March

  Definition : Endometrial intraepithelial carcinoma (EIC) is a recently described lesion characterized by replacement of endometrial surface epithelium or glands by malignant cells resembling high-grade invasive endometrial carcinoma.
  EIC has been identified in a high proportion of uteri containing serous carcinoma, but its association with other endometrial tumors is unknown.
  EIC is frequently and specifically associated with uterine tumors displaying serous differentiation.
