Uterine tubes, also known as the Fallopian tubes, serve as a connection between the ovaries and the uterus. It is where fertilization usually takes place.

This was ignored in the past... current thinking is that it may be the real culprit in what is often labeled as "ovarian cancer".[1]

Normal uterine tube

Architecture:

  • Finger-like projections into the lumen.

Cells:

  1. Ciliated cell.
    • Columnar.
    • Eosinophilic cytoplasm.
  2. Non-ciliated cell (AKA Peg cell).
    • Nucleus more luminal.
      • Nuclei stick-out like a golf tee.
  3. Secretory cells.

Images:

Overview

Benign lesions

Benign neoplasm

Pre-malignant

Malignant diagnoses

  • Serous carcinoma.
  • Endometrioid adenocarcinoma.[3]

Ditzels

Main article: Ditzels

Paratubal cyst

General

  • Very common.
  • May lead to ovarian torsion if very large.[4]

Gross

  • Thin walled-cyst with serous fluid.

Microscopic

Features:

  • Simple cyst with ciliated (tubal) epithelium.

Sign out

PARATUBAL CYST, RIGHT, EXCISION:
- BENIGN SIMPLE CYST.

No epithelium

PARATUBAL CYST, LEFT, EXCISION:
- BENIGN FIBROUS TISSUE COMPATIBLE WITH CYST WALL.

Tubal ligation

  • Abbreviated TL.

General

  • Done to control fertility.

Microscopic

See normal uterine tube.

- FALLOPIAN TUBE WITHIN NORMAL LIMITS.

Surgical resection of previous tubal ligation

LEFT FALLOPIAN TUBE AND OVARY, LEFT SALPINGO-OOPHORECTOMY:
- FALLOPIAN TUBE WITH PARATUBAL CYSTS AND FOCAL FIBROSIS.
- OVARY WITHIN NORMAL LIMITS.

Specific diagnoses

Salpingitis

Also suppurative salpingitis.
Also granulomatous salpingitis.

General

  • Benign.
  • May be part of pelvic inflammatory disease.

Microscopic

Features:

  • Inflammatory cells:
    • Neutrophils = acute.
    • Lymphocytes and plasma cells = chronic.
  • +/-Granulomas; known as granulomatous salpingitis.
  • +/-Clusters of neutrophils = abscess; known as suppurative salpingitis.

Images:

Stains

If organisms are seen on routine stains:

  • Gram stain +ve/-ve.

Granulomatous inflammation:

Adenofibroma

General

  • Rare.[5]
    • More frequently seen than in the past -- presumably as pathologists are looking more closely at the Fallopian tube.
  • Cannot be disguished from ovarian adenofibroma.[5]

Gross

  • Solid, nodular.

Microscopic

Features:[5]

  • Stroma + glandular elements.
    • Glandular elements: secretory cells and ciliated cells.

IHC

Features:

  • Stroma:[5]
    • CD10 +ve.
    • Inhibin +ve.

Salpingitis isthmica nodosa

  • Abbreviated SIN.
  • AKA adenosalpingitis,[6] and diverticulosis of the Fallopian tubes.[7]

General

Diagnosis (clinical):

  • Hysterosalpingography.[10]
    • Finding: diverticula.

Notes:

Microscopic

Features:[11]

  • Nodular thickening of the tunica muscularis of the isthmic portion.
  • Cystically dilated glands.
  • +/-Complete obliteration of tubal lumen.

Images:

Adenomatoid tumour

See: Adenomatoid tumours (uterine tumours).

General

  • Relatively common tumour of the fallopian tube.[12]

Microscopic

See: Adenomatoid tumours (uterine tumours).

Serous tubal intraepithelial carcinoma

  • Abbreviated STIC.[13]
  • AKA tubal intraepithelial carcinoma.
