Hi, my dog has a bump on her ear for 6 months or so. We visited our vet when we found the bump. That time, our vet said if it gets bigger then we should come back. I saw some blood from the bump a few weeks ago(after she went to a beach and swam). The bump area's skin is hard. I don't think it's getting bigger. It doesn't look itchy. But I'm afraid that it might be a mast cell tumor. Are the chances high that it's just Lipoma or Histiocytoma?

By it's look only it's not possible to tell what type of tumor it is. this lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Sunny to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

This growth on Blu could be a cyst, a benign tumor, or a malignant tumor. Any suspicious growths should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the growth to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Blu seen by a vet tomorrow to have the growth examined and diagnosed so it can be treated as needed.

It looks as though your dog has a fairly inflamed mass or cystic lesion on his ear. The only way to definitively determine the cause of the mass is through a fine needle aspirate where a vet draws a few cells out of the lesion with a needle (it's quick and relatively painless!) before examining the cells microscopically. From there, you will have a better sense as to whether the lesion is benign or malignant and whether or not surgical removal is needed. The other concern is that this lesion appears quite red with discharge and may be infected if your dog has been scratching at it. The vet will also be able to determine if antibiotics are needed at the time of the exam. I hope that all goes well!
