The leg tumour grows from grape size to kiwi to apple to mango size in a few weeks

Likely a malignant mast cell tumour as it reappears at its original site on the left hind limb. 5 years ago, Vet 1 excised a small tumour with 1-cm resection margin. Histology shows neoplastic cells at the edges of the excised tumour.

5 years later, a grape-sized tumour was discovered on the same spot. Vet 2 did a fine needle aspirate which drew no cells. The tumour grew from small grape sized to kiwi ro apple and now mango-sized when they came to Toa Payoh Vets.
Vet 2's senior surgeon said that FNA could have caused the tumour to expand. I disagreed as it was a recurring malignant tumour and so do grow aggressively. The senior surgeon gave 2 choices with no guarantees of success:  1. amputate the left limb    2. excise the tumour. The dog could die on the operating table owing to old age high anaesthetic risks. The owner decided not to operate and the tumour grew to the mango-sized when they came to Toa Payoh Vets. Dr Daniel was the surgeon for this case.
