Mastocytoma in cats, not exactly like in dogs, but it remains a tumor that one always hopes not to encounter. However, it is important to inquire to understand what it is exactly, without lightly decline in the feline version what we may already know in the canine one.
Mastocytoma in cats: what is it
It is not as frequent as in dogs, the mast cell tumor in cats, but we can find it both on the skin and in the internal organs, also called visceral. In general when we talk about mast cell tumors we mean that round cell tumor whose name derives from those cells to which it is related, the "mast cells". They are cells containing a large number of small granules of various kinds. In the diversity that composes them, we find and mention heparin and histamine because they play a leading role in mast cell tumor in cats.
Mastocytoma in cats: causes
Knowing and explaining the causes of a tumor is not at all simple, this also applies to the specific case of mast cell tumor in cats, one of those not particularly frequent, fortunately. The cases of mast cell tumor in cats they are about 3% of reported neoplasms, usually involving middle-aged or elderly specimens. The average age of the felines diagnosed with a mast cell tumor is 10 years old and are usually FeLV negative.
When we stated that the mast cell tumor in cats it is not identical to that in the dog, it is because in the feline case it can present itself in both cutaneous and visceral form, even the two forms can coexist. Cases where this occurs and when does the cat with mast cell tumor presents a cutaneous mast cell tumor which then reveals itself also in the liver or spleen, therefore also in visceral form.
It is less frequent to happen but it can also happen that the animal is diagnosed with visceral form and then you notice at a later time the presence of skin nodules.
Mastocytoma in cats: symptoms
If the mast cell tumor in cats cutaneous can also be visible, the visceral one must be recognized through its symptoms that we find described in a vague way. It is very easy to confuse them with those of other, even completely different, pathologies. Let's get to know them, though: they are anorexia, vomiting, splenomegaly, diarrhea, presence of masses in the abdomen.
Once you are satisfied that it is mast cell tumor in cats any skin nodule can be removed, but if the shape is visceral it becomes necessary to remove the spleen. When you manage to do so, your life prospects are lengthened, especially if you continue on treatment with prednisone-based therapy, also suitable for cats with the gastroenteric form.
Mastocytoma in the cutaneous cat
The cutaneous form of mast cell tumor in cats It is characterized by the presence of nodules that can be in any area of the body although there are areas that are more prone to this type of tumor and are the head and neck. Nodules can also be multiple and are divided into mast cells and histiocytes.
The former are the most common, composed of a single mass and appear in specimens older than 4 years. The mast cell tumor in cats histiocytic skin type has a series of masses that sometimes regress on their own, the Siamese breed is the one that is most affected.
Mastocytoma in the visceral cat
The visceral form creates problems both at the blood level and at the level of the gastrointestinal system but we can also talk about mast cell tumor in cats systemic if the blood and lymphatic vessels are affected, i.e. blood, spleen, liver and bone marrow.
Unfortunately, most of the time you notice the presence of this type of very late mast cell tumor, when they are already present metastases to the liver, spleen, lung and mesenteric lymph nodes. First, the signs of the gastrointestinal form are vomiting and diarrhea because the blood tests may also show perfect.
