Endometriosis causes significant morbidity and is associated with increased risk of certain malignancies.

Clinical

  • A cause of infertility.
  • A cause of pelvic pain.
  • Affects approximately 10% of women of child bearing age.
  • Associated with moderate elevation of (serum) CA-125.

Diagnosis

Criteria - need at least 2 / 3 for the diagnosis:[1]

  1. Endometrial glands - endometrial glands are classically: circular, with nuclei that are hyperchromatic & cigar-shaped.
  2. Endometrial stroma - endometrial stroma is classically: cellular and hyperchromatic (may resemble a lymphocytic infiltration on low power).
  3. Hemosiderin-laden macrophages - light brown, may be granular.

Notes:

  • The epithelial component (1) may appear cuboidal in cysts or be sloughed-off, i.e. absent.
  • The microscopic correlation of chocolate cyst is: light brown acellular material; this can be considered as a substitute for (3) - hemosiderin-laden macrophages.
  • Epithelial component may have tubal metaplasia.[2]
  • Endometriosis may mimic cancer - see image below.
  • If it is just endometrial type glands... it is probably endosalpingiosis.

Images

Associations

Endometriosis is associated with:

Immunohistochemical stains

  • CD10 stains the stromal cells[7] - used to look for endometriosis.
