Uterine tubes

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.

Cross section of a Fallopian tube with decidualization. H&E stain. (WC/euthman)

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. (???)
    • Basal cells, fried egg-like.

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

  • Salpingitis - low mag. (WC)

  • Salpingitis - high mag. (WC)

  • Granulomatous salpingitis - intermed mag. (WC)

  • Granulomatous salpingitis - high mag. (WC)

Stains

If organisms are seen on routine stains:

  • Gram stain +ve/-ve.

Granulomatous inflammation:

Ectopic pregnancy

Main article: Ectopic pregnancy

Adenofibroma

General

  • Rare.[6]
    • More frequently seen than in the past -- presumably as pathologists are looking more closely at the Fallopian tube.
  • Cannot be disguished from ovarian adenofibroma.[6]

Gross

  • Solid, nodular.

Microscopic

Features:[6]

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

IHC

Features:

  • Stroma:[6]
    • CD10 +ve.
    • Inhibin +ve.

Salpingitis isthmica nodosa

  • Abbreviated SIN.
  • AKA adenosalpingitis,[7] and diverticulosis of the Fallopian tubes.[8]

General

Diagnosis (clinical):

  • Hysterosalpingography.[11]
    • Finding: diverticula.

Notes:

Microscopic

Features:[12]

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

Adenomatoid tumour

See: Adenomatoid tumours (uterine tumours).

General

  • Relatively common tumour of the fallopian tube.[13]

Microscopic

See: Adenomatoid tumours (uterine tumours).

Serous tubal intraepithelial carcinoma

  • Abbreviated STIC.[14]
  • AKA tubal intraepithelial carcinoma.
