Different types of biopsies?

Hello everyone,

 

I did an internet search on these terms, but I want to make sure if I understood this properly. These are the biopsies I know

 

1. FNAC: You get a needle and aspirate cells

 

2. True cut (core) biopsy: You get a bigger needle and aspirate tissue rather than cells.

 

3. Incisional biopsy: You take a piece of the tissue of interest. Eg if there is an ulcer, you take a wedge shape part of it for histopathology.

 

4. Excisional biopsy: You take the whole tissue of interest. Eg removing whole lobe of thyroid, to look for follicular carcinoma.

 

Questions

 

1. Did I understand these terms properly, my biggest confusion is incisional and excisional biopsy, did I get that right?

 

2.. Are there any other biopsy types I don't know of.

 

Thank you so much :)

With regard to incision and excision: yes, incision is a cut into something whereas in a excision you cut something out. What specifically is being targeted depends on context. An excision could be just affected tissue, for example.
