Wen (lipoma) in dogs

Wen in dogs, it is also called lipoma, a fairly common phenomenon. Many owners find tumor-like formations on their pets' bodies and panic. Indeed, for most people, a tumor is associated with cancer. However, in this case, there is no talk of any cancer disease. What to do if a pet has a lipoma?

Causes of Wen in Dogs

First of all, it is worth considering what a lipoma is. This is a benign growth that consists of fatty tissue. The study of this disease did not give an exact answer, what is the exact cause of the emergence of Wen in dogs. Among the many existing hypotheses are the following:

  • genetic predisposition;
  • direct inheritance of the disease;
  • unfavorable ecological situation;
  • the slagging of the animal;
  • impaired renal and hepatic activity.

The formation of a lipoma occurs due to blockage of the sebaceous glands or due to the localized growth of fatty tissues, therefore their appearance is associated with impaired metabolic processes in the body, which leads to a deficiency of the protein enzyme.

Lipoma Complications

In most cases, wen on the body of the pet is quite harmless, but there are exceptions. Despite the seeming harmlessness of lipomas, certain risks still exist. There have been cases of degeneration of wen into a malignant tumor - fibrosarcoma. This can occur in dogs at risk of cancer. But initially malignant fat cells (liposarcoma disease) are rarely diagnosed.

In addition, wen in dogs can grow very large, making it difficult for an animal to move. Often, their increase leads to the fact that large fat formations begin to put pressure on the internal organs. Wen, in certain situations, can be very painful.

Growing and becoming more, wen increases so much that it is in a hanging position. This situation threatens to impair blood flow in the lipoma itself and the death of its upper part. And this is already an open way for infectious agents to enter the body of an animal.

Large as well as drooping wen can cause a dog pain, as they exert pressure not only on nearby tissues, but also often squeeze the nerve roots.

Dangerous wen with dark pigment is a sure sign that the formation absorbs ultraviolet radiation. Yes, and aesthetics such education does not add. In any case, the appearance of the wen is a good reason to visit the vet.

Who is at risk

Most often, benign growth of adipose tissue is observed in the following groups of animals:

  • middle-aged and older dogs (read to what age dogs grow );
  • more often in females (50% of cases) than in males;
  • obese pets.

I must say that this form of lipoma is quite common. Infiltrative lipoma (liposarcoma) is very rare in both dogs and cats. Among the recorded cases, it was noted that most often this malignant formation is diagnosed in labrador dogs.

Lipoma in a dog

Features Wen

Lipomas can be formed in almost any area of ​​the body that has adipose tissue. The most frequent places of their formation are the subcutaneous layers of fiber on the sternum, peritoneum and upper parts of the legs. Rare are Wen, appearing on the surface of internal organs - on the liver, stomach, intestines, lungs, etc. Naturally, this form of the disease requires diagnosis in the clinic, because the usual way it does not recognize.

Lipoma can form one or form a multiple accumulation of tumors, a disease called lipomatosis. Sometimes with the appearance of Wen, symmetry of their location can be observed.

Difficult are considered diffuse formations that are localized in the intermuscular space of limbs. Most often they are a plurality of clusters of nodes, which does not allow them to be effectively treated.

How to recognize lipoma

You can do this by examining the education and feeling it. Usually, the lipoma is similar to a swelling of the skin, smooth, oval in shape. There are also solid Wen, but in most cases they are soft and mobile to the touch. Palpation does not cause a pet's pain or discomfort if the formation is not too large. Wen can not grow for a long time, remaining in the same condition.

Diagnosis of the disease

The description of a lipoma often allows it to be confused with other similar formations, therefore differential diagnosis is very important in identifying this formation. During a visit to the veterinary clinic, you can find out that the lipoma on the pet's body is not a wen, but an abscess (this can be detected independently, since the skin becomes very hot at the site of infection), a hematoma (bruise), an inflamed lymph node, or a malignant formation .

According to statistics, among all visits to veterinarians with swelling of the skin, in 10% of dogs, they are really wen.

The following methods are used to diagnose veterinarians:

  • palpation (palpation of the swollen area);
  • sampling puncture biopsy (taken from the tissue of the deepest layers of the tumor);
  • excision of a small part of the tumor surgically.

The latter method is often used when the lipoma in a dog has already burst. In this case, the speed of data acquisition is important and urgent surgical intervention is required. Naturally, without the obtained results, confirming that this is really a lipoma, the operation will not be carried out.

Malignant (infiltrative) education is detected by conducting a histological (pathological) study. This formation is more often found between the muscle tissues of the upper part of the paws, as well as in the retroperitoneal space.

Infiltrative lipoma requires surgery - excision of the affected areas, followed by radiation therapy. Doctors can not give accurate predictions, as this kind of tumor very often recur.

Treatment Methods for Wen

Unfortunately, traditional therapy is powerless against a lipoma; only surgical intervention will help. Lipoma does not have a tendency to metastasis and after complete excision does not form in the same area. Remove the wen, or leave everything as is, only a specialist decides.

Remove the wen from the dog

If a wen chooses subcutaneous tissue as a site of localization, then most often it does not cause concern. If it does not provoke pain and inconvenience, is small, then you can not send your pet for surgery.

If it cannot be avoided, then it is necessary to prepare a pet — not to give food for a day, but not to disturb the water regime. If the dog's lipoma has already burst, then the operation is done urgently.

How does this procedure go:

  1. The wen is in the capsule and has some blood vessels. After the surgeon cuts the layers of the skin over the formation, he separates the lipoma from the surrounding tissues.
  2. Such formations practically do not bleed when, but sometimes the dressing of the main vessel that feeds the lipoma is still required.
  3. As soon as the wen is removed, the doctor carefully sews up the cavity that was formed during the operation.

Much more difficult is the situation with intermuscular lipomas, good, there is such a variety infrequently. They grow almost imperceptibly, while they are particularly aggressive. These tumors are located in the intermuscular layers, scattered across the territory in separate fragments. The lack of boundaries of education makes the operation extremely difficult. The growth of the intermuscular lipoma is accompanied by an increase in the size of the paw, the pet begins to limp and feel pain. Removal of such formation does not guarantee the absence of its reappearance.

After the operation, the dog needs care. Postoperative suture should be regularly treated with antiseptics. See that the animal does not lick, scratch this place. You can use special collars in which the pet will not be able to reach the place of the incision.

In most cases, surgery completes safely and after 1.5 weeks you can visit a doctor in order to remove the stitches.
