There are several reasons why the cat gets lumps and bumps in the skin. In some cases, it may be a malignant tumor, so if you find a lump in your cat’s skin, it is best to see a veterinarian to have it examined.
Different Types Of Benign New Formations And Tubers
- Cysts in the skin – A common form of cyst in the skin is atheroma, sebaceous gland cyst, but cyst formation can also be seen in other skin structures. Atheroma means that sebum has accumulated in a sebaceous gland in the skin, instead of being emptied out on the skin surface as it should. This manifests itself as a lump that can often be small and of unchanged size, but which can also grow relatively quickly and cause discomfort to the cat. It is not uncommon for a well-filled sebaceous gland cyst to rupture and empty its contents, after which it becomes small in size again. It also happens that the atheroma becomes infected.
- Inflammatory reactions, abscesses, etc. – a local inflammation can be triggered by, for example, insect or tick bites, a sting or other foreign object. The most common cause of abscess is bite injury , and then it is usually a major swelling. This type of lump occurs relatively quickly, within a few days or a week and often causes some form of discomfort to the cat (pain, itching, etc.).
- Benign tumors – a tumor is an accumulation of cells that grows into uncontrolled tumors. A benign tumor does not grow into the surrounding tissue and it does not metastasize, ie does not spread to other parts of the body. If the tumor is in an inappropriate place, it can bother the cat, but usually these tumors give no symptoms. Benign tumors in the skin can develop from all the different cell types of the skin, such as pigment cells (melanocytoma), skin cells (eg epithelium) or glandular cells (adenoma) and they are usually slow-growing. A common benign tumor, which usually resides in the subcutaneous tissue, is lipoma .
In connection with the clinical examination, the veterinarian often takes samples from the tuber with the help of a cannula (so-called fine needle aspirate) and examines this under a microscope. Depending on the cat’s temperament and the location of the tuber, you may need to give the cat a sedative before taking the sample. In some cases, tissue samples (biopsies) are taken or the entire tuber is removed and analyzed in its entirety. Such procedures are performed under anesthesia or with sedatives and local anesthesia.
Treatment And Prognosis
The treatment varies depending on what the tuber in question consists of. The prognosis for benign new formations is good, but some problems may be recurrent, including atheroma.
