Hi toolwoman,.

Options are to surgically remove the cyst that way it does not keep rupturing on him and getting infected. I know that he is older and I don't know what his anesthetic risk may be. You may want to get some routine bloodwork run beforehand just to see how his major organs are functioning. Your vet will probably give him a rectal exam to make sure that this cyst doesn't extend further in that just skin and it isn't involving the rectum or colon. The other option is medical treatment which usually involves soaking of the wound and systemic antibiotics. Sometimes we use topical antibiotics also.

Are these usually cancerous?
Expert:  Dr. P replied 8 years ago.
well there are 2 types: perianal adenoma which is non cancerous. They can still rupture and get infected. There is also perianal adenocarcinoma which is. You can't tell really by just looking at it. Sometimes you can look at some of the cells under a microscope. If you do get it removed, you can have the tissue sent out for a biopsy so that a histopathologist can rule if it is cancerous or not. Many dogs with a cancerous periianal tumor will also have an elevation in their blood calcium level
