Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))

Gross processing

Paratubal cysts can be ignored if incidentally found.

(Look in the history for any intra-fallopian coils (Essure devices).)[note 2]

For sterilization
  • Measure length and average diameter of each tube
  • Serially section at 3-4 mm intervals,[1] or 2-3 mm if suspected malignant (including BRCA mutation).[2] Submit
  • Submit 1 (or 3) circumferential transverse sections. If the specimen is only a segment of the tube of less than <5mm((, ink the surgical cut surfaces and)) submit all tissue.[1]

Example gross report:

(A. Labeled - __. The specimen is received in formalin and consists of) two fimbriated segments of fallopian tube measuring __ cm in length and __ cm in average diameter. On sectioning, each displays a patent lumen. No gross abnormalities are identified. The tubes are unoriented. The specimen is serially cross-sectioned and representative sections are submitted for microscopic examination in two cassettes.

Microscopic examination

Fallopian tubes may be substantially edematous and congested, which can generally be attributed to surgery, in which case it does not need mention in the report.
  • Ensure there is at least one full cross-section from each tube, and take further samples otherwise.
  • Check for patency of the lumen.

Neoplasias

Look for:

  • Adenomatoid tumor, the most common tumor of the fallopian tubes:[3]
  • An adenomatoid tumor of the fallopian tube, low magnification, displaying infiltrative-like borders.
    An adenomatoid tumor of the fallopian tube, low magnification, displaying infiltrative-like borders.
  • High magnification of the same case, showing the typical[3] features of tubular spaces of varying size composed of flattened cells resembling endothelium.
    High magnification of the same case, showing the typical[3] features of tubular spaces of varying size composed of flattened cells resembling endothelium.
  • Atypia/crowding of the serous epithelium.
Serous tubal intraepithelial lesion (STIL).[4] H&E staining shows mildly atypical tubal epithelium with largely preserved polarity. Immunohistochemistry demonstrates aberrant block-type p53 expression but a low Ki-67 proliferation index, insufficient for classification as serous tubal intraepithelial carcinoma (STIC).

Reporting

Example of a normal report in sterilization:

(Right and left fallopian tubes, ((laparoscopic)) bilateral salpingectomy:)
Complete cross-sections of histologically unremarkable fallopian tubes.

When included in a uterus specimen, normal tubes and ovaries may simply be mentioned as:

Bilateral fallopian tubes and ovaries, unremarkable.
Histopathology of an ectopic pregnancy in a fallopian tube, with chorionic villi and implantation site changes Further information: Products of conception .

When done for ectopic pregnancy, report any rupture, either from the gross report or from microscopy, for example:

Benign ruptured fallopian tube with ectopic products of conception, including degenerated immature chorionic villi and implantation site with fresh hemorrhage.

Further information: Products of conception

Notes

  1. ↑ For a full list of contributors, see article history. Creators of images are attributed at the image description pages, seen by clicking on the images. See Patholines:Authorship for details.
  2. ↑ For a case with intra-fallopian coils in the medical records, an inability to find them on gross processing must be noted in order to raise the possibility of coil expulsion.
