Pet parents who find a new lump on their dog should have it examined by a veterinarian. Mast cell tumors can look like benign, subcutaneous fatty lipomas or other seemingly innocent types of growths on a dog's skin, so all new growths should have a fine needle aspirate test. If caught...

Mast cell tumours occur in the dog, particularly in the boxer and related breeds, in the skin and less frequently in the intestines. Cytology usually provides an accurate diagnosis, but histological examination adds further information concerning the histologic grade and the completeness of surgical ...
The mast cells observed in all lesions were uniform and highly granulated, and with the presence of the microfilariae, a mast cell tumor was considered less likely. This report suggests that D repens infection-associated subcutaneous lesions, characterized cytologically by massive mast cell and ...
Lingual mast cell tumour in a cat A 12-year-old male neutered domestic shorthair cat was presented for staging and treatment recommendations of a lingual mast cell tumour (MCT). Cytology after fine-needle aspiration of the mandibular lymph nodes revealed regional metasta... BC Sommer,BK Flesner...
Figure 6.5 Cytology of canine cutaneous MCTs. (A) Mast cell granules fill the cytoplasm and are extracellular in this MCT, Wright’s stain. The cytoplasm of well differentiated MCTs stain intensely with Wright’s or Diff‐Quik. However, the granules in some MCTs will not stain reliably with ...

A mast cell tumor is very easy to diagnose with cytology. If the pathologist doesn't feel that it is a mast cell tumor then it is extremely unlikely to be one. If you're seeing some pus then this also confirms that antibiotics could be helpful. It sounds like your vets are doing a ...
