Hamartomas are a form of cancer found in dogs. Spotting them is difficult because they resemble other, benign, tumors. Consult your veterinarian for diagnosis and treatment options.

Definition
-
Hamartomas in dogs are masses of disorganized mature tissue that appears at one specific exterior site. Older dogs are prone to them.
Causes
-
The specific cause of hamartomas in dogs is not known. Cancer usually is the result of a series of circumstances from previous damage or continued trauma to a specific area.
Signs
-
Signs of hamartoma include hairless or ulcerated areas on limbs or pressure points.
Diagnosis
-
Diagnosis relies on a form of biopsy called a histopathology performed by a veterinary pathologist.
Affliction
-
Hamartomas can ulcerate and bleed, which may cause secondary infection at the site. A hamartoma can take years to become noticeable.
Treatment and Care
-
The best treatment is surgical removal of the affected area. The tumor can reduce in size, but often remain as a solid mass which must be removed. Prevent your dog from rubbing, licking, scratching or biting at the infected site before and after surgery.
