Endosalpingiosis
Diagnosis in short

Endosalpingiosis. H&E stain.
LM cystic lesion with ciliated epithelium surrounded by fibrous stroma, psammoma bodies
LM DDx endometriosis, serous carcinoma, adenocarcinoma, peritoneal inclusion cyst
IHC CK7 +ve, WT-1 +ve, CA125 +ve
Site peritoneum, omentum, lymph node (rare)
Clinical history may be associated with endometriosis; incidental finding
Prognosis benign

Endosalpingiosis is a benign entity that can be confused for cancer.

General

  • Benign entity that may lead to a misdiagnosis of adenocarcinoma[1] or serous carcinoma.
  • The clinical significance of endosalpingiosis is not definitively settled; opinions differ on whether it is:
    1. associated with pelvic pain,[2] or
    2. an incidental finding discovered in the course of investigating something else (pelvic pain, menstrual irregularities, infertility).[3]

Microscopic

Features:[4]

  • Cystic lesions with:
    • Ciliated (tubal type) epithelium, without endometrial stroma.
      • Endosalpingiosis is surrounded by fibrous stroma; tubal type epithelial surrounded by ovarian stroma is a variant of endometriosis.
  • Associated with psammoma bodies.[5]

Notes:

  1. Not associated with hemorrhage.[6]
  2. In a lymph node, endosalpingiosis may be misinterpreted as a metastasis![7]

DDx:[8]
