Hemangiopericytoma is a malignant tumor that develops from pericyte cells, which are found around small blood vessels (capillaries) in dogs. Although this type of tumor can occur in any dog breed, it is more commonly seen in large breeds. Early detection and treatment are critical to preventing further health complications. This article highlights the importance of recognizing early signs and explores the various treatment options available for hemangiopericytoma in dogs.
What Causes Hemangiopericytoma in Dogs?
Pericytes are connective tissue cells that surround blood vessels, playing a key role in supporting the vascular system. Under normal circumstances, these cells can differentiate into other types of tissue cells, helping with regeneration and repair. However, when abnormal cell division occurs, a tumor like hemangiopericytoma can develop. The exact cause remains unknown, but factors such as genetics, environmental exposure, or trauma may contribute to tumor formation.
Symptoms and Warning Signs
Hemangiopericytomas are slow-growing tumors that usually develop in the subcutaneous tissue. While the tumor may not be noticeable at first, as it grows, it may cause physical discomfort or visible changes. Common symptoms include:
- A firm lump or mass beneath the skin
- Swelling or localized pain around the tumor
- Lethargy or reduced physical activity, especially if the tumor affects movement
- Signs of discomfort if the tumor presses on vital organs or joints
- Difficulty breathing if the tumor develops in the chest area
Though the tumor is most often localized, in rare cases, it can metastasize to other parts of the body, particularly the lungs or liver.
Diagnosing Hemangiopericytoma
If your dog develops a lump or shows symptoms that may indicate a tumor, a visit to the veterinarian is essential. A thorough physical examination, followed by a biopsy of the mass, is typically the first step in diagnosing hemangiopericytoma. Advanced imaging techniques such as CT scans or MRIs may also be used to assess the size and location of the tumor, as well as to check for possible metastasis.
Treatment Options for Hemangiopericytoma
The main treatment for hemangiopericytoma is surgical removal of the tumor. Since these tumors can be deeply embedded in the tissue, the surgery may need to be extensive to ensure complete removal and reduce the risk of recurrence. In cases where the tumor cannot be fully excised, or if it is located in a sensitive area such as the chest, radiation therapy may be employed to shrink the tumor before surgery.
Chemotherapy is another option, especially if the tumor has spread to other organs. Although not always required, it can be useful in advanced cases to help control the disease. Post-operative care is crucial, with regular follow-up appointments to monitor for any signs of recurrence.
予後と予防
The prognosis for dogs diagnosed with hemangiopericytoma largely depends on early detection and successful removal of the tumor. In most cases, the outcome is favorable if the tumor is caught before it grows too large or metastasizes. Pet owners should be proactive in regularly checking for any lumps or abnormalities on their dog’s skin, especially if they own a large-breed dog.
While it is impossible to prevent hemangiopericytoma, maintaining a healthy lifestyle for your dog with a balanced diet, regular exercise, and routine vet check-ups can help improve their overall well-being and resilience to health issues.
Hemangiopericytoma is a serious yet treatable condition in dogs, particularly in large-breed dogs. Understanding the early symptoms and exploring all available treatment options can make a significant difference in managing the disease. If you notice any unusual lumps or changes in your dog’s behavior, seek veterinary attention promptly to ensure the best possible outcome.

Brain tumors in dogs can be a challenging diagnosis for pet owners, often raising concerns about the severity and treatment options. A brain tumor is an abnormal growth of tissue that can occur within the brain or its surrounding structures. While some tumors are benign, meaning they are not cancerous, others are malignant and can spread or invade other parts of the body. This article will provide a comprehensive overview of the types of brain tumors in dogs, their causes, and the potential treatment options available.
Types of Brain Tumors in Dogs
- Primary Brain Tumor
A primary brain tumor originates directly in the brain or its protective layers, known as the meninges. These tumors arise from cells within the brain and do not initially spread from other parts of the body. Common primary brain tumors in dogs include meningiomas, gliomas, and pituitary tumors. They tend to occur more frequently in older dogs but can also affect younger animals in rare cases.
- Secondary Brain Tumor
Secondary brain tumors develop when cancer from another part of the body metastasizes or invades the brain. Metastasis occurs when cancerous cells travel through the bloodstream or lymphatic system from a primary tumor elsewhere in the body, while invasion involves the tumor extending into nearby tissues. Cancers such as lymphoma, melanoma, and hemangiosarcoma are known to metastasize to the brain.
Signs and Symptoms of Brain Tumors in Dogs
The symptoms of brain tumors in dogs can vary depending on the tumor’s location, size, and growth rate. Some common signs include:
- Seizures, especially in dogs that have no prior history of seizures
- Behavioral changes, such as confusion, disorientation, or aggression
- Difficulty walking, coordination problems, or weakness
- Changes in vision or loss of sight
- Head tilt or abnormal head positioning
- Circling or pacing
- Lethargy or decreased energy levels
If your dog shows any of these symptoms, it’s important to seek veterinary care as soon as possible.
Causes of Brain Tumors in Dogs
The exact cause of brain tumors in dogs is often unknown, but several factors may contribute to their development:
- 年齢: Brain tumors are more common in older dogs, particularly those over the age of seven.
- 犬種による素因: Certain breeds, such as Boxers, Golden Retrievers, and Boston Terriers, are more prone to developing brain tumors.
- Genetics: In some cases, genetics may play a role in the development of tumors.
- 環境要因: Exposure to environmental toxins or carcinogens may also contribute to the formation of brain tumors.
Diagnosis of Brain Tumors in Dogs
Diagnosing a brain tumor in dogs typically involves advanced imaging techniques, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. These diagnostic tools allow veterinarians to visualize the brain and identify any abnormal growths. In some cases, a biopsy may be necessary to confirm the type of tumor.
犬の脳腫瘍の治療法
- 手術
For primary brain tumors, surgery may be a viable option, especially if the tumor is accessible and can be safely removed. Surgical removal can significantly improve the quality of life and prognosis in some cases, but it may not always be possible depending on the tumor’s location.
- 放射線治療
Radiation therapy is commonly used to treat brain tumors that cannot be surgically removed or as a follow-up to surgery. Radiation can shrink tumors and help control their growth, providing relief from symptoms.
- 化学療法
Chemotherapy is less commonly used for brain tumors, as it is difficult for many drugs to penetrate the blood-brain barrier. However, it may be effective in certain cases, particularly with secondary tumors that have metastasized to the brain.
- 緩和ケア
For dogs with advanced brain tumors or those not candidates for surgery or radiation, palliative care focuses on managing symptoms and improving quality of life. This may include medications to control seizures, reduce pain, or alleviate other symptoms caused by the tumor.
Brain tumors in dogs can be a serious and life-altering condition, but with early detection and proper treatment, many dogs can continue to enjoy a good quality of life. If you notice any concerning signs or symptoms in your dog, it’s important to consult your veterinarian for a thorough evaluation and to discuss the best treatment options for your pet.

Ear cancer in dogs is a serious condition that often requires prompt treatment to prevent complications. While ear cancer is relatively uncommon, when it does occur, it can affect any part of the ear, including the pinna (outer ear flap), ear canal, middle ear, and inner ear. Knowing the available treatment options can help pet owners make informed decisions and improve their dog’s chances of recovery.
Surgical Treatments for Canine Ear Cancer
- Partial or Total Pinnectomy
When cancer affects the pinna, or outer ear flap, the most common treatment is a partial or total pinnectomy. In a partial pinnectomy, only the cancerous part of the ear flap is removed. If the tumor is more extensive, a total pinnectomy, which involves removing the entire ear flap, may be necessary. While the appearance of the ear will change, this procedure can prevent the cancer from spreading to other parts of the body.
- Total Ear Canal Ablation with Lateral Bulla Osteotomy (TECA-LBO)
When cancer affects the ear canal, a more involved surgical procedure, called total ear canal ablation with lateral bulla osteotomy (TECA-LBO), is often recommended. This surgery involves removing the entire ear canal and opening the bony structure at the base of the ear (the tympanic bulla) to remove infected or cancerous tissue. While this procedure may reduce the dog’s hearing in the affected ear, it can effectively eliminate the cancer and prevent further complications.
放射線治療
Radiation therapy may be recommended for tumors that cannot be completely removed surgically or for tumors located in difficult-to-reach areas, such as the middle or inner ear. This therapy involves targeting the tumor with radiation to destroy cancerous cells. Radiation therapy is typically administered over multiple sessions, with each treatment requiring the dog to be anesthetized.
Chemotherapy for Metastatic Cancer
If the cancer has metastasized (spread to other parts of the body), chemotherapy may be an option. Chemotherapy involves the use of drugs to kill or slow the growth of cancer cells. While chemotherapy is often used alongside surgery or radiation therapy, it may also be used as a stand-alone treatment for more aggressive or widespread cancers.
Supportive Care for Dogs with Ear Cancer
In addition to surgical and non-surgical treatments, supportive care plays a critical role in managing ear cancer in dogs. After surgery, pain management is essential for ensuring a smooth recovery. Veterinarians will typically prescribe pain medications to keep your dog comfortable. Antibiotics may also be necessary to prevent or treat infections, especially after surgery.
When it comes to treating ear cancer in dogs, surgical removal of the tumor is often the first step. Depending on the location and severity of the cancer, additional treatments such as radiation therapy or chemotherapy may be required. If your dog has been diagnosed with ear cancer, consulting with your veterinarian about the best treatment plan is crucial for ensuring your pet’s health and well-being.

Ear tumors in dogs can develop in any part of the ear, from the outer pinna to the deeper sections of the ear canal and inner ear. While some ear tumors are benign and grow slowly without spreading, others are malignant and require immediate medical attention. Understanding the signs of ear tumors and knowing what to watch for can help you catch any issues early and improve your dog’s chances of successful treatment.
What Are Ear Tumors?
Ear tumors refer to abnormal growths that appear in or around a dog’s ear. Not all tumors are cancerous, but they should still be closely monitored and evaluated by a veterinarian. Ear cancer is a specific type of ear tumor that is malignant, meaning it grows aggressively and may spread to other parts of the body. Tumors in the ear can affect the pinna (outer ear), the ear canal, the middle ear, and even the inner ear.
Common Areas Where Ear Tumors Develop
- Pinna (Outer Ear)
The pinna, or outer flap of the ear, is more commonly affected by ear tumors, especially in dogs with droopy ears or ears that are exposed to the sun for long periods. Tumors here are often easier to detect during grooming or petting.
- External Ear Canal
The external ear canal is the passage leading into the ear that contains both a vertical and horizontal section. Tumors here may cause symptoms like head shaking, scratching, or visible swelling.
- Middle Ear
The middle ear, located behind the eardrum, contains small bones that transmit sound. Tumors in this area can affect a dog’s hearing and balance, causing more serious symptoms like head tilting or difficulty walking.
- Inner Ear
The inner ear controls hearing and balance. While tumors in this region are rare, they can cause severe balance issues and neurological symptoms if they occur.
Signs and Symptoms of Ear Tumors in Dogs
It’s important for pet owners to recognize the signs of ear tumors early. Common symptoms include:
- 頭を振ったり掻いたりする: Persistent head shaking or pawing at the ear may indicate irritation caused by a tumor.
- Discharge or foul smell: Tumors can lead to an infection, causing foul-smelling discharge from the ear.
- Visible lumps or swelling: Growths on the pinna or near the ear canal can be seen or felt, especially during grooming.
- 難聴: Tumors affecting the ear canal or middle ear can block sound, leading to partial or complete hearing loss.
- Balance issues: If a tumor affects the inner ear, your dog may experience problems with balance, such as wobbling or falling.
Diagnosing Ear Tumors in Dogs
If you notice any unusual symptoms in your dog’s ears, it’s important to consult a veterinarian as soon as possible. Your vet may perform a physical exam, imaging tests (such as X-rays or CT scans), and a biopsy to determine whether the tumor is benign or malignant. Early diagnosis can help ensure the best treatment options are available.
治療の選択肢
Treatment for ear tumors depends on whether the tumor is benign or malignant:
- Benign tumors can often be surgically removed if they are causing discomfort or obstructing the ear canal.
- Malignant tumors may require more aggressive treatment, including surgery, radiation therapy, or chemotherapy. In severe cases, partial or full removal of the affected ear may be necessary to prevent the spread of cancer.
Ear tumors in dogs, whether benign or malignant, should never be ignored. Regularly check your dog’s ears for any lumps, swelling, or unusual symptoms. If you notice any changes in your dog’s behavior or ear health, contact your veterinarian for a thorough evaluation. Early detection is key to improving outcomes, especially for malignant ear tumors.
