If any lymph nodes are enlarged or feel abnormal, further sampling may be pursued to determine if spread is present. WHAT IS THE DIFFERENCE BETWEEN A NEEDLE ASPIRATE AND A BIOPSY? Dogs with a ruptured splenic mass requiring a blood transfusion are more likely to be diagnosed with hemangiosarcoma. These tumors can be massive (comprised of a single large tumor), or nodular (several discrete masses within one or multiple liver lobes), or diffuse (involvement of the entire liver). Other primary hepatic tumors Myelolipoma is a non malignant tumor of the hepatobiliary origin.

In the case of fibrosarcomas, although no specific risk factors or cause have been identified, sarcomas in general (tumors of the connective tissue) have been associated with radiation, trauma, foreign bodies, and orthopedic implants. Results. The hepatocellular carcinoma is an important tumor of dogs and cats, not only because it is moderately common but because it tends to be amenable to surgery even though it is malignant.
