Respiratory small biopsies

Background

Pulmonary needle biopsies, video-assisted thoracoscopic (VATS) and open pulmonary (surgical lung) biopsies are all methods for investigating pulmonary disease such as pneumonia and tumours. 1

For wedge biopsies, see the lung protocol.


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.

The potential for an infectious biohazard should always be considered with fresh specimens but particularly with respiratory samples due to the possibility of mycobaterial infections. 1 Ensure strict safe specimen handling and decontamination protocols are in place in the laboratory.

See general information for more detail on specimen handling procedures.

Inspect the specimen and dictate a macroscopic description.

Follow best practice procedures to minimise cross over contamination of small fragments to other specimens. 2

Describe the following features of the specimen: 1

Procedure

Record as stated by the clinician.

Options
  • Video-assisted thoracoscopic (VATS) biopsy 1
  • Open biopsy –for lung wedge biopsies, see the lung protocol
  • Needle biopsy
  • Transthoracic needle biopsy 3
  • Incisional biopsy
  • Other, describe 4,5

Biopsy site

  • Lung
  • Pleura
  • Bronchus
  • Mediastinal mass
  • Other, describe

Number of pieces*

  • Record the number of pieces of tissue received

Specimen dimensions (mm)

  • Each fragment in three dimensions
  • Where multiple fragments are present, the range of maximum sizes may be appropriate*

*“Multiple” should only be used to describe specimens where biopsies are too numerous to count.

Colour (more than one may apply)

  • Tan
  • Red
  • Yellow
  • White

Consistency (more than one may apply)

  • Firm
  • Soft
  • Polypoid
  • Friable

Not required.

Internal InspectionBack to top


Not required.

ProcessingBack to top


Submit all tissue directly into cassettes for processing. Biopsy pads, lens paper or similar are required to prevent loss of tissue during processing.

Record details of each cassette.

An illustrated block key similar to the one below may be useful.
