Causes
An atheroma typically forms in the skin or subcutaneousSubcutaneous means "under the skin." In medicine, it refers to the administration of drugs or the placement of implants directly under the skin. tissue of a dog. It is a closed capsule filled with a pasty, white or yellowish substance containing sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi.. Sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. is an oily secretion produced by the sebaceous glands to keep the skin and coat supple.
The scientific basis for the formation of atheromas lies in the blockage of sebaceous glands or hair follicles. This blockage can be caused by dead skin cells, hair follicles, or sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. itself. An atheroma is a retention cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. in which the natural outflow of sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. is blocked, leading to the accumulation of material within the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause..
The causes for the development of atheromas are varied. Genetic factors can play a role, as certain dog breeds have a higher predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. to the formation of cysts. These include, for example, Cocker Spaniels and Basset Hounds. Environmental factors such as poor hygiene or frequent skin irritations can also contribute to the formation of atheromas.
Hormonal changes, especially in unneutered dogs, can affect the production of sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. and thereby increase the risk of developing atheromas. In addition, an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or inflammation of the sebaceous glands can block the outflow of sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. and lead to the formation of cysts.
Symptoms
The symptoms of an atheroma in dogs are usually easy to recognize. The cysts are usually palpable as small, round bumps under the skin. They are usually not painful and can develop over a long period of time.
Affected dogs often show no signs of discomfort as long as the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. is not infected or inflamed. In some cases, the skin over the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. may appear reddened or irritated, especially if the dog tries to lick or scratch the affected area.
If an atheroma becomes infected, it can lead to swelling, redness, and pain. In such cases, inflammation or even ruptureA rupture is a tear or break in an organ or tissue. It can be caused by trauma, illness, or overextension, and often requires medical intervention. of the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. may occur, requiring veterinary treatment.
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of an atheroma in dogs is usually made by a thorough physical examination by a veterinarian. The veterinarian will examine and palpate the affected area to determine the texture of the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause..
In some cases, a fine needle aspiration may be performed to take a sample of the contents of the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause.. This sample is examined under the microscope to confirm the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. and rule out other possible conditions, such as tumors or abscesses.
Additional diagnostic tests, such as X-rays or ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow. examinations, may be required if there is suspicion of deeper tissue involvement or if the veterinarian suspects other underlying problems.
Therapy
The treatment of an atheroma in dogs depends on the size, location, and condition of the cyst. In many cases, especially if the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. is small and not infected, observation may be sufficient, as atheromas often do not cause any discomfort.
If the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. is large or infected, or if it bothers the dog, surgical removal may be necessary. This procedure is usually performed under general anesthesiaGeneral anesthesia is a medical procedure that induces unconsciousness and eliminates pain during surgical procedures. It involves the use of anesthetics to temporarily shut down the body's overall perception., and the entire cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. is removed to prevent recurrence.
After the removal of an atheroma, antibiotic treatment may be necessary if there is an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.. The veterinarian may also prescribe pain medication to support postoperativePostoperative refers to the time after a surgical operation. This phase includes recovery and the management of possible complications after the procedure. recovery.
In some cases, the veterinarian may recommend regulating the dog’s sebaceous gland function with special shampoos or diets to reduce the risk of relapses or new atheromas.
Prognosis and follow-up care
The prognosis for dogs with atheromas is generally very good. Since these are benignBenign refers to a non-invasive, non-serious condition that is not life-threatening. In medicine, the term is often used to describe benign tumors that do not metastasize, meaning they do not form secondary tumors. cysts, there is no risk of malignantMalignant means "cancerous" and is used to describe tumors or neoplasms that grow invasively and have the ability to metastasize.

After surgical removal, the risk of recurrence at the same site is very low, provided the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. has been completely removed.
However, in dogs that are prone to forming atheromas, new cysts may appear in other locations. Regular monitoring and early treatment can help avoid complications.
Complications are rare but occur if the cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. becomes infected or could not be completely removed during removal. Overall, the quality of life of affected dogs is hardly limited as long as the cysts are treated appropriately.
Prevention
The preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of atheromas in dogs can be supported by good skin care and regular coat care. Regular brushing and bathing of the dog can help remove dead skin cells and excess sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. that can lead to blockage of the sebaceous glands.
A balanced diet, specifically tailored to the needs of the dog, can also help promote skin health and regulate sebumsebum is the oily substance produced by the skin's sebaceous glands. It helps keep the skin and hair supple and provides some protection against bacteria and fungi. production. The veterinarian may recommend supplements containing omega-3 and omega-6 fatty acids to support skin and coat health.
For dogs that are genetically predisposed, regular examination by a veterinarian can help detect and treat atheromas early. Early intervention can help avoid complications and reduce the need for surgical procedures.
In some cases, neutering or spaying a dog can help influence hormonal factors that can contribute to the formation of atheromas. However, this should be discussed individually with the veterinarian to make the best decision for the respective dog.

It consists of a capsule filled with a pasty massIn pathology, the term "mass" is used to describe an abnormal lump or growth in the body. A mass can form in the skin or subcutaneous tissue, or even inside the body. The causes can be benign (not cancer) or malignant (cancer). of dead skin cells, oil, and keratin. Researchers are currently focusing on better understanding the exact mechanisms of formation of these cysts in order to develop preventive measures and identify the best possible treatment methods.
One area of current research is investigating genetic factors that may contribute to the formation of atheromas. Some studies suggest that certain breeds are more susceptible to developing these cysts, indicating a genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases.. Researchers are analyzing genetic markers to determine whether certain genes can be linked to a higher likelihood of atheroma occurrence. These investigations could lead to the development of targeted breeding programs in the long term to reduce the risk of atheromas in affected breeds.
Another field of research is dedicated to investigating the role of nutrition and environmental factors in the development of atheromas. Scientists are exploring whether certain diets rich in healthy fats and nutrients can reduce the risk of cystA cyst is a closed sac that may contain fluid, air, or other material. Cysts can occur in any part of the body and vary in size and cause. formation. In parallel, it is being investigated whether environmental factors such as skin care products or environmental pollution play a role in the development of these cysts. These findings could lead to new recommendations for the care and nutrition of dogs to reduce the risk of atheromas.
Regarding the treatment of atheromas, research is currently being conducted on the development of less invasiveInvasive describes medical procedures or pathogens that enter the body or penetrate tissue.
