Dog Skin Allergies
Skin lumps are very common in dogs. There are a number of possible scenarios that may arise as a bump on the skin, including insect bites, abscesses, hematomas, cysts, soft tissue swelling following trauma and benign or malignant . The tumors are probably the most benign of these sums, but two-thirds of them, and therefore merely cosmetic. Here we have the most common cancers affecting the skin and subcutaneous tissue > Dogs, and what, if any, treatment they need.
Dog Skin Allergies
When you are presented with a skin tumor, a veterinarian must address two problems.
Dog Skin Allergies
First, there is a type of cancer that requires surgical removal
Dog Skin Allergies
2, additional treatment is necessary when it was removed
Some are benign tumors of the skin so clear that the vet will not even bother to biopsy, not to mention to recommend revocation. And 'the little wart' as tumors that are often connected by a narrow strip of skin. AllSkin Cancer> that do not fit this category, however, a fine needle aspiration (a needle into the ground, sucking some of the cells under a microscope and characterization) or to undergo a surgical biopsy. This will determine if a complete withdrawal is necessary, and defining prognosis.
A thorough clinical examination is important to evaluate both the tumor and the patient as a whole. A veterinarian will examine the relationship of the tumor to its size, position andAppearance, and check the local and regional lymph nodes to look for evidence of metastasis.
What is the difference between benign and malignant tumors?
Benign tumors are usually slow growing and may change a little 'more than a year. They usually have a head start and lead the dog a little 'problems, but can sometimes cause problems when they are ulcerated or start to bleed following trauma itself.
Malignant tumors often developrapidly over a few weeks. They tend to ulcerate soon run their course, and can penetrate into the surrounding tissue, apparently solid and less mobile than benign tumors.
Benign tumors of the skin
Snow and tags
These are not the tumors are benign skin growths that are stable and well-defined present at birth but may develop later in life.
Warts and papillomas
These are benignThe tumors that may develop spontaneously or be triggered by a virus.
Sebaceous cysts
This is more common in dogs (approximately 7% of all skin cancers). They are not cancer, but the accumulation of sebum in the gland from a blocked duct, which can often be solved by tightening.
Sebaceous hyperplasia
This is the proliferation of the sebaceous glands of cauliflower-like warts on it, which can ulcerate traumatized formand bleed. They are very common in old cocker spaniel and poodle. Surgical excision or cryotherapy with liquid nitrogen is healing.
Basal cell tumors
More common in cats than dogs. Usually appear as rounded, well-circumscribed mass in the pink, hairless skin. They tend to travel on the underlying structures, and are slow growing. Surgical excision is curative.
Histiocytoma
Usually seen in young dogs by18 months, but can occur at any age. They grow rapidly for about six weeks to a maximum size of about 2 cm and are dome-shaped lumps in the hairless skin to rot, can. The crucial step is to distinguish mast cell tumors, histiocytomas veterinarian (see below), which can be done easily through a fine needle aspiration. Surgical excision or cryotherapy is healing for histiocytoma, and many will disappear naturally without treatment.
BenignSubcutaneous tumors
Lipoma
The lipoma is the most common cancer in dogs subcutaneously. It is a well-defined and well-circumscribed mass with a soft and chewy. They have slow growth and a very common event has become so great in older dogs are overweight. You can be the basis of experience or members, and even if they are completely harmless, sometimes it can show are a nuisance for the dog and only then is surgeryExcision is required. Before becoming a song is a lipoma, it is advisable to have a vet in a fine-needle aspiration of the nodule, like a couple of other tumors may mimic a lipoma, as presentations of mast cell (see below), and hemangiopericytomas.
Malignant tumors of the skin
Epidermoid
This is a common malignancy in dogs and cats. It usually occurs in relatively smooth, notpigmented skin and can be triggered by long exposure or repeated exposure to UV rays. Surgical excision is curative, as a rule, if the margins are satisfactory, and cases with incomplete margins benefit from postoperative radiation therapy to kill any remaining cancer cells. Some squamous cell carcinomas are very difficult to remove, but as an evil infiltrating, which occurs on the nasal planum. Chemotherapy was used for this type of mixed tumorResults.
Melanoma
Relatively common in most dogs. They are benign and surgical excision is curative. However, those on the nail bed, the scrotum or the mucocutaneous junction (eg, lips) the results of the vicious rule. Surgical removal is mandatory.
Mast cell
These are among the most common skin tumors in dogs. They have a wide range of appearance and behavior so that it is sometimes a challengeto diagnose and treat. About 10 percent of dogs suffer from multiple locations.
Mast cells are present naturally in the skin, resulting in a important role in the release of histamine and heparin in the allergic response to various stimuli. As with any cell line, mutations can occur, where the cells begin to divide uncontrollably, forming tumors. If a mast cell tumor is compressed and is therefore a reaction of histamine wheal skin. Histamine can also causeVomiting so affected dogs may have gastrointestinal problems.
If a mast cell tumor is confirmed on a fine-needle aspiration, which should be operational as soon as possible, ideally cut. In the case of well-defined tumors that are caught relatively early, is usually curative. The margins of 2 to 3 cm is recommended. However, high-grade tumors tend to be aggressive and invasive complete excision is not always possible. In these cases, partial excision or radiotherapyChemotherapy is the treatment of choice.
In dogs, mast cell tumors tend to be subject to time and again in the future, even if removed surgically in a hurry. Therefore the owners of these dogs their skin dogs carefully inspected at regular intervals to check all suspicious nodes.
