Lumps & Bumps

Find a mysterious lump on your dog? If you are concerned, the best thing is to come in to the vet to have it diagnosed. In most cases, the mass can be diagnosed by the appearance, location, and feel of it. Sometimes, an aspiration cytology (examining the content of the lump under a microscope) is necessary. If the mass appears especially suspicious, removal and/or histopathology may be recommended. A histopathology can determine the type of mass, the level of malignancy, and whether the mass has been completely removed. The following is a list of the most commonly diagnosed masses.


Cutaneous Histiocytoma

Sebaceous Adinoma
