Liver tumors and cancers – mar cutaneous histiocytoma vista animal medical center

The confirmation of a liver tumor requires a medical diagnostic cutaneous histiocytoma journey starting with perhaps a sick pet or perhaps simply cutaneous histiocytoma an abnormal lab test result found incidentally and proceeding through cutaneous histiocytoma further blood tests and ultimately imaging. Through imaging of the abdomen the liver lobes can be cutaneous histiocytoma evaluated and the presence of a tumor verified. We will assume that you are reading this because the cutaneous histiocytoma diagnostic process has largely been completed and a tumor is cutaneous histiocytoma present. At this point undoubtedly many questions have emerged and must cutaneous histiocytoma be answered in order to make proper choices.

Many of these questions listed above can be answered by cutaneous histiocytoma ultrasound, the most common medium for evaluating the texture of the cutaneous histiocytoma liver. Unlike radiography, where all soft tissue appears as the same texture, ultrasound is able to separate out tissues depending on their cutaneous histiocytoma water content. This means that it is possible to see inside the cutaneous histiocytoma liver and see if there is one tumor or many cutaneous histiocytoma and how much normal liver texture is left. Ultrasound can determine what organs show tumor inside, whether or not local lymph nodes are enlarged (which could indicate spread of the tumor), and whether or not surgery would be useful. It is also possible to take either a needle aspirate cutaneous histiocytoma or actual biopsy to determine the type of tumor and cutaneous histiocytoma knowing the type of tumor will answer remaining questions regarding cutaneous histiocytoma treatment options, survival time, etc. In other words, if ultrasound of the liver has not been done yet, it is time to do it.

A needle aspirate involves sticking a long needle into the cutaneous histiocytoma abnormal area and withdrawing cells for analysis. This is usually done with ultrasound guidance so as to cutaneous histiocytoma avoid hitting any large blood vessels and to make sure cutaneous histiocytoma the desired area is sampled. The advantage of the needle aspirate is that anesthesia or cutaneous histiocytoma sedation of the sick patient is generally not necessary, there is less potential for bleeding than with biopsy, and results may be obtained as soon as overnight in cutaneous histiocytoma many cases. The disadvantage is that the sample obtained consists of cells cutaneous histiocytoma only and the architecture connecting these cells is lost. Diagnosis will be less specific and may consist of conceptual cutaneous histiocytoma information like benign vs. Malignant, inflammatory vs. Not-inflammatory etc. Some tumors, such as the mast cell tumor or lymphoma readily release cutaneous histiocytoma their cells and architecture is not needed for diagnosis. Other tumors are not so readily distinguished and there is cutaneous histiocytoma greater potential for the frustrating “non-diagnostic sample” result than there is with a biopsy.

A biopsy yields a very different sample: an actual chunk of tissue. In this type of sample, the microscopic structures of the liver can be viewed as cutaneous histiocytoma can the cells infiltrating them. The architecture of the tissue is preserved. Tumors can be graded for the degree of malignancy plus cutaneous histiocytoma the specific type of tumor is revealed. The downside stems from the fact that a larger piece cutaneous histiocytoma of tissue is required. Clotting tests must be run prior to the procedure to cutaneous histiocytoma insure the liver will not bleed. A different type of needle is used and some sort cutaneous histiocytoma of sedation is typically needed which may add risk. Results typically take longer for a biopsy sample as the cutaneous histiocytoma laboratory preparation is more complicated. Expense is generally greater for biopsy than for aspirate.

If cancer is found in the liver but is believed cutaneous histiocytoma not to have originated there, this indicates cancer spread and very advanced disease. Prognosis is poor though what options remain depend on the cutaneous histiocytoma type of cancer present. Metastatic disease in the liver is approximately two and a cutaneous histiocytoma half times more common than primary cancer in the liver cutaneous histiocytoma with most tumors having spread from the spleen, pancreas, or intestinal tract. If your pet appears to be in this situation and cutaneous histiocytoma you want to obtain all the options possible for palliation cutaneous histiocytoma of the disease, it is best to consult with an oncology specialist.

Again, a primary liver tumor is a tumor that arose in cutaneous histiocytoma the liver (rather than having spread there from a primary tumor elsewhere). Primary tumors are classified by their shape/configuration within the liver and by the type of liver cutaneous histiocytoma tissue they originated from. Tumors may be massive, nodular, or diffuse. The best type to have is the “massive” type as this type is present in one area and cutaneous histiocytoma is thus the most amenable to surgical removal. A “diffuse” tumor involves the entire liver evenly while a “nodular” tumor forms discreet bumps within the liver. While ultrasound can tell us if a tumor is “massive,” “nodular,” or “diffuse.” it cannot tell us the tissue of origin.

The hepatocellular adenoma is benign and does not cause illness. It might cause some blood changes which might, in turn, trigger a medical work up but if a biopsy turns cutaneous histiocytoma up this tumor in an otherwise healthy pet, the news is good and nothing bad should be expected cutaneous histiocytoma to come of this tumor. Alternatively, if this diagnosis is made in a pet that it cutaneous histiocytoma sick, the illness probably cannot be blamed on this tumor and cutaneous histiocytoma a further search for the right diagnosis is warranted.

The hepatocellular carcinoma is an important tumor of dogs and cutaneous histiocytoma cats, not only because it is moderately common but because it cutaneous histiocytoma tends to be amenable to surgery even though it is cutaneous histiocytoma malignant. In humans, this tumor often has a viral basis (i.E. One of the hepatitis viruses) as well as an association with cirrhosis (scarring in the liver) but in dogs and cats neither of these associations holds cutaneous histiocytoma true.

If the patient, dog or cat, has a massive tumor surgery can greatly improve life quality cutaneous histiocytoma even if the entire tumor cannot be removed. The hepatocellular carcinoma grows very slowly so surgery, while challenging, typically produces excellent results. The risks of surgery include bleeding, circulatory compromise to the remaining liver portions, reduced liver function after surgery, and transient low blood sugar. The time of greatest risk and concern is the time cutaneous histiocytoma of the surgery and during surgical recovery. After recovery, one study found a median survival time of 1460 days. If the tumor is present on the right side of cutaneous histiocytoma the liver, surgery is more difficult as the vena cava, the largest vein in the body, is very close by and may bleed. The bottom line is that massive disease should be addressed cutaneous histiocytoma with surgery with potential for cure while nodular or diffuse cutaneous histiocytoma disease has a poor prognosis.

There are two types of bile duct tumors to be cutaneous histiocytoma had by dogs and cats: biliary adenoma (benign) and biliary carcinoma (malignant.) the biliary adenoma is the most common primary liver tumor cutaneous histiocytoma in the cat and accounts for over 50% of all feline primary liver tumors. They are cystic in structure meaning they tend to be cutaneous histiocytoma large and fluid-filled. They do not cause problems until they are so big cutaneous histiocytoma that they press on other organs but because they are cutaneous histiocytoma fluid-filled, the fluid can be periodically sucked out with ultrasound guidance cutaneous histiocytoma to restore health or the tumor can be removed surgically cutaneous histiocytoma once and for all.

Primary sarcomas of the liver are unusual but include: hemangiosarcoma (a malignancy of blood vessels which is a common secondary cutaneous histiocytoma tumor but only 5% of hemangiosarcomas arise in the liver), fibrosarcoma (malignancy of fibrous tissue), osteosarcoma (bone malignancy), and leiomyosarcoma (smooth muscle malignancy). Approximately 36% of sarcomas are massive and 64% are nodular with metastasis found in 80-100% of cases depending on the study. Massive tumors of other types are generally amenable to surgery cutaneous histiocytoma but in the case of sarcomas, there is usually tumor spread already present. Some tumors can be treated with chemotherapy.
