Benign Bone Tumour
Jack, a 2-year-old male German Shepherd was seen for a fast-growing solid lump that had appeared on his right lower neck.
It had grown over a few weeks. It was rigid with an irregular shape, and approx. plum sized. It was not worrying Jack.
Mark performed a needle biopsy and got a milky white fluid with some odd shaped cells. X-rays showed a solid growth in the right lower neck adjacent to the spine and windpipe, with a speckled bony appearance.
We decided to explore the lump to see if it could be removed and to get a good sample of it for the pathologist to examine. Jack was placed on a drip and given IV Alfaxan, and placed on Isoflurane gas to keep him anaesthetised.
Mark had to split his neck muscles first one direction and then the other to access the tumour.
It was firmly attached to the surrounding muscles and cervical vertebrae. It took over an hour to slowly free it of its attachments before it was removed. The space left behind had a Penrose drain placed in it to drain away any blood that might accumulate.
The muscle layers were closed with dissolving sutures then the skin was sutured.
Jakck was given post-op pain relief and antibiotics.
The tumour was sent to a pathologist who diagnosed a benign growth called Calcinosis Circumscripta. They are found in young large breed dogs often over an area of trauma. Even though they look nasty, they are benign.
Jack made a great recovery is back to running down the beach and being up to mischief.
