  Endometrial intraepithelial carcinoma (EIC)
  Definition: Endometrial intraepithelial carcinoma (EIC) is non-invasive, morphologically the same as serous carcinoma, and positive for p53 and stains strongly for Ki-67.
  EIC is a precursor of serous carcinoma.
  IHC
  Endometrioid intraepithelial carcinoma (EIC) is positive for p53 and Ki-67.

• atypical polypoid adenomyoma
  10 May

  Atypical polypoid adenomyoma is biphasic: it has a stroma composed of fascicles of smooth muscle, and numerous atypical epithelial glands that have architecturally lost polarity but are not pleomorphic, as seen here. There are minimal mitotic figures, and squamous metaplasia is frequently found.
  Atypical polypoid adenomyoma is composed of 1) fascicles of smooth muscle, 2) atypical epithelial glands, and (frequently) 3) squamous (...)

  Differential diagnosis
  endometrial stromal tumors (ESTs) endometrial stromal tumors may pose diagnostic challenges particularly when they exhibit variant histologic appearances, involve extrauterine sites, or present as metastatic disease. In such cases, use of immunohistochemical markers and identification of specific nonrandom chromosomal rearrangements may be helpful. endometrial stromal nodule (ESN): Stromal nodule does not have atypical mitoses, and has a lower number of mitosis. (...)

  Synopsis
  Also known as glandular and stroma breakdown
  Common in perimenopausal women
  condensation of endometrial stroma under surface endometrium and nuclear dust;
  associated with predecidualized stroma and glandular exhaustion;
  cannot assess architectural changes;
  may see signet ring cells (benign) if prolonged shedding

  |PO|
  Weakly proliferative endometrium: Normal in prepubertal girls, perimenopausal or menopausal women Proliferative glands (columnar or cuboidal epithelium with pseudostratification, elongated and densely basophilic nuclei), but relatively reduced number of mitotic figures Glands usually tubular or cystic, may be closely packed Stroma also appears inactive with variable collagenization and minimal mitotic activity
