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:
- Ciliated cells.
- Columnar.
- Eosinophilic cytoplasm.
- Peg cells.
- Nucleus more luminal.
- Nuclei stick-out like a golf tee.
- Nucleus more luminal.

Tubal ligation
General
- Done to control fertility.
Microscopic
See normal uterine tube.
DDx:
- Salpingitis - inflammatory cells.
- Serous carcinoma - nuclear atypia (marked), nuclear pleomorphism, prominent nucleoli.
- Tubal intraepithelial carcinoma - discrete papillary growth, loss of nuclear polarity, nuclear atypia.

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:
- Ziehl-Neelsen stain +ve/-ve.
- GMS stain +ve/-ve.
- PASD stain +ve/-ve.
Adenofibroma
General
- Rare.[3]
- More frequently seen than in the past -- presumably as pathologists are looking more closely at the Fallopian tube.
- Cannot be disguished from ovarian adenofibroma.[3]
Gross
- Solid, nodular.
Microscopic
Features:[3]
- Stroma + glandular elements.
- Glandular elements: secretory cells and ciliated cells.
IHC
Features:
- Stroma:[3]
- CD10 +ve.
- Inhibin +ve.
Salpingitis isthmica nodosa
General
- Associated with infertility and ectopic pregnancy.[6]
- SIN is uncommonly bilateral.[7]
Diagnosis (clinical):
- Hysterosalpingography.[8]
- Finding: diverticula.
Notes:
- The male cousin of this is: vasitis nodosa.
Microscopic
Features:[9]
- 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.[10]
Microscopic
See: Adenomatoid tumours (uterine tumours).
Serous tubal intraepithelial carcinoma
General
- Considered the precursor lesion for tubal serous carcinoma.[12]
Gross
- Not apparent on gross.
- Usually at the fimbriated end of the tube.
Microscopic
Features:[13]
- Discrete papillary growth - low power.
- Formal criteria - need 3 or more:
- Atypical chromatin pattern.
- Nuclear enlargement.
- Nuclear pleomorphism.
- Nuclear moulding.
- Loss of nuclear polarity or epithelial stratification.
Image:
IHC
Features:[11]
- p53 +ve.
- Ki-67 +ve.
- p16 +ve.[13]
