Hello, my name is***** and I have over 20 years of experience as a veterinarian. I'm sorry to hear that Maci has a bump/ball on her back that started as a pimple.

This sounds like a sebaceous cyst. What you are seeing from the outside is just the tip of the iceberg so to speak. Sebaceous cysts are mostly under the skin and consist of a pocket lined with oil glands that are producing sebaceous material into a central pocket under the skin. This is great food for bacteria and they can easily become inflamed and infected leading them to rupture, and they often have a "pimple" looking top surface.

Ideally we treat the cyst with antibiotics and shrink it as much as possible, then surgically remove what is left. If we don't remove the abnormal pocket of glands then the cyst will continue to grow and probably become a problem again, with a larger area rupturing open. Treating the top of the cyst with antibiotic ointment does not address the true problem underlying the skin.

That said it is sometimes possible to use systemic antibiotics to shrink the cyst and have it remain quiescent for a while. It would be reasonable to try that. If the skin refuses to heal even with systemic antibiotics, or the cyst starts to enlarge again then we know that surgery really is our only option.

Please let me know if you have any further questions.
