3 Ways to Diagnose Skin Masses on Dogs

Introduction:
Dogs, like humans, can develop various skin masses on their bodies. Some may be benign or a natural part of aging, while others can signal a more serious issue. As a pet owner, it’s essential to recognize and diagnose these skin masses in order to provide the best care for your furry friend. Here are three ways to diagnose skin masses on dogs.
1. Visual Inspection and Palpation:
The first step in diagnosing a skin mass on your dog is through a thorough visual inspection. Start by closely examining your dog’s skin, searching for any unusual lumps, bumps, or growths. Once you have identified a mass, carefully feel it by using your fingers. Assess its size, shape, texture, and mobility to gather information about the potential nature of the growth.
A benign mass may be small, soft, round or oval-shaped and easily moveable as it is not attached to any underlying structure. On the other hand, malignant masses may be larger, irregularly shaped, firm or hard and may be fixed in place. While this information can help you make an informed judgment about your dog’s health, it’s crucial not to solely rely on these factors when determining if a mass is malignant or benign.
2. Fine Needle Aspiration (FNA):
One of the most common diagnostic procedures used to identify skin masses is called Fine Needle Aspiration (FNA). During an FNA, a veterinarian uses a thin needle to collect a small sample of cells from the mass for further examination under a microscope (cytology).
Cytology allows the veterinarian to determine if the mass is made up of cells from fatty tissue (commonly indicative of a benign tumor called lipoma), inflammatory cells (suggesting an infection), or abnormal cells (possibly suggestive of cancer). While FNA isn’t always definitive in its results, it can provide valuable information for further diagnostic steps.
3. Biopsy and Histopathology:
If a skin mass cannot be conclusively diagnosed through FNA, a biopsy may be recommended. A biopsy involves surgically removing a small portion of tissue (incisional biopsy) or the entire mass (excisional biopsy). This tissue sample is then sent to a veterinary pathologist for histopathological analysis under a microscope.
Histopathology can provide detailed information about the nature of a mass, whether it is benign or malignant, and its specific type. This information is crucial when determining an appropriate treatment plan for your dog.
Conclusion:
The detection and diagnosis of skin masses on dogs are vital aspects of maintaining their overall health. Keep an eye on your dog’s skin during regular grooming sessions and contact your veterinarian if you notice any unusual growths. By utilizing these three diagnostic methods, you can work with your vet to identify skin masses and ensure the best possible care for your canine companion.
