I'd like to introduce you to Allie Johnson. Allie is a twelve year old spayed female husky that we recently saw for the removal of a very large tumor which had slowly been developing on her right side. Several issues were of concern prior to Allies' surgery and were investigated before deciding to move forward with the procedure. Previously we had removed approximately two liters of fluid from the tumor leading to the suspicion that we would find a primary mass underneath the skin incision. As these photos show, there was a large tumor under the skin which was attached to the chest wall. More often than not, it is difficult to differentiate between a malignant and a benign tumor on visual inspection. This tumor however was very disorganized in its appearance and stimulated such a tremendous response from the local tissue we suspect it is, in fact, malignant. It is our hope that we were able to remove it in its entirety, however, due to its invasive nature, this may not be possible.Allie has recovered well from the surgery and we await the pathological report. Further treatment may be possible based on this report and the implications of the tumor type.
