The Biopsy Report
The term biopsy (Bx) refers to the removal and examination, gross and microscopic, of tissue or cells from the living body for the purpose of diagnosis. A variety of techniques exist for performing a biopsy of which the most common ones are:
- Aspiration biopsy or bone marrow aspiration: Biopsy of material (fluid, cells or tissue) obtained by suction through a needle attached to a syringe.
- Bone marrow biopsy: Examination of a piece of bone marrow by needle aspiration; can also be done as an open biopsy using a trephine (removing a circular disc of bone).
- Curettage: Removal of growths or other material by scraping with a curette.
- Excisional biopsy (total): The removal of a growth in its entirety by having a therapeutic as well as diagnostic purpose.
- Incisional biopsy: Incomplete removal of a growth for the purpose of diagnostic study.
- Needle biopsy: Same as aspiration biopsy.
- Percutaneous biopsy: A needle biopsy with the needle going through the skin.
- Punch biopsy: Biopsy of material obtained from the body tissue by a punch technique.
- Sponge (gel foam) biopsy: Removal of materials (cells, particles of tissue, and tissue juices) by rubbing a sponge over a lesion or over a mucous membrane for examination.
- Surface biopsy: Scraping of cells from surface epithelium, especially from the cervix, for microscopic examination.
- Surgical biopsy: Removal of tissue from the body by surgical excision for examination. Total biopsy: See excisional biopsy.
Note: Any biopsy can be processed quickly by a frozen section technique or by routine fixation (permanent section) by H and E (Hematoxylin and Eosin) stain which usually takes 48 hours to prepare.
