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
Need 2 of 3 criteria to diagnose.
Criteria:[1]
- Endometrial glands - endometrial glands are classically: circular, with nuclei that are hyperchromatic & cigar-shaped.
- Endometrial stroma - endometrial stroma is classically: cellular and hyperchromatic (may resemble a lymphocytic infiltration on low power).
- 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 cholocate 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... to the initiated eye.
Images
- Endometriosis - ovary (WC).
- Endometriosis - low mag. (WC).
- Endometriosis - high mag. (WC).
- Endometriosis in small intestine - low mag. (WC).
Associations
Endometriosis is associated with:
- Endometrioid adenocarcinoma of the ovary[3]
- Clear cell carcinoma of the ovary.[4]
- Increased endocrine tumours, non-Hodgkin's lymphoma, brain tumours and decreased cervical cancer.[5]
- Endocervical-like mucinous borderline tumor.[6]
