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

General

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.

Rare stuff:

  • There case reports of endometriosis in men on estrogen therapy for prostate cancer.[1][2]

Gross

  • Chocolate cyst = cyst containing light brown material.

Microscopic

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

  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.[4]
  • Endometriosis may mimic cancer[5] - see images below.
  • If it is just endometrial type glands - the stroma is missing... it is probably endosalpingiosis.

Mimicking cancer:

Associations

Endometriosis is associated with gynecologic tumours:

  1. Endometrioid adenocarcinoma of the ovary[6]
  2. Clear cell carcinoma of the ovary.[7]
  3. Endocervical-like mucinous borderline tumour (EMBT).[8]
    • Mixture of EMBT and serous borderline tumor = seromucinous borderline tumour.

Other tumours & decreased risk:[9]

Immunohistochemical stains

  • CD10 stains the stromal cells[10] - used to look for endometriosis.
