Gynaecological small biopsies
A range of small biopsies from lesions of the cervix, vagina, vulva and peritoneum are received.1-4 Separate protocols are provided for endometrial curettings and biopsies, and products of conception.
Record the patient identifying information and any clinical information supplied together with the specimen description as designated on the container. See overview page for more detail on identification principles.
- Non-routine fixation (not formalin), describe.
- Special studies required, describe.
- Ensure samples are taken prior to fixation.
Follow best practice procedures to minimise cross over contamination of small fragments to other specimens.5
Orientate and identify the mucosal surface if possible. Some specimens will be received mounted on card or filter paper with mucosal surface uppermost.
Handle fragments with care to preserve the delicate epithelial tissue.
See general information for more detail on specimen handling procedures.
Inspect the specimen and dictate a macroscopic description.
See also the Structured Pathology Reporting Protocol for Cervical pre-neoplasia.
Describe the following features of the specimen:
Describe as stated by the clinician.
- Cervical punch biopsy
- Vaginal biopsy
- Vulval biopsy
- Perineal biopsy
- Peritoneal biopsy
- Other, specify
- Number of fragments
- If <3 pieces, record the maximum dimension (mm) of the smallest and largest piece of tissue.
- If >3 pieces, measure the aggregate size of the tissue.
Larger pieces of tissue (>5mm in maximum dimension) including polyps may be measured in three dimensions. For cysts, record the maxium dimension and wall thickness.
- If >5mm, three dimensions (mm)
- Maximum dimension (mm)
- Thickness of wall
Not required in most circumstances. Larger pieces of tissue, polyps and cysts may be bisected transversely, perpendicular to the mucosal surface.
Submit all tissue directly into cassettes for processing. Biopsy pads, lens paper or similar are required to prevent loss of tissue during processing.1,3
Be aware that blood clot and mucus may not survive processing.
Record details of each cassette.
An illustrated block key similar to the one below may be useful.
