This patient was presented for a rapid growing large mammary mass which extended from the left mammary glands to the right side. Surgical removal of this mass was challenging due to the size of the mass and the skin availability for primary closure after the mass removal. Luckily feline skin is relatively elastic therefore the defect was able to close with primary closure with minimal tension. It is important to have a backup plan prior to the procedure. I was prepared to perform skin flaps if required and fortunately it’s not needed in this case. The mass was sent out for histopathology and came back as benign tumor.

Most feline mammary tumors are 90% malignant and 10% benign. (She was the lucky one!)
For Canine, 50% of mammary tumors are malignant and 50% are benign.
