Melanomas in Dogs and Cats
Melanomas are pigmented tumors that may be benign or malignant, often in dark-skinned dogs such as Cocker Spaniels and Scottish Terriers. They favor the mouth, eyes, rectum, and perineum, with mucosal sites most at risk. Wide removal is used, but malignant forms carry a poor outlook.
Sebaceous Adenomas in Dogs and Cats
Sebaceous adenomas are usually benign, curable skin tumors of older dogs and cats, most often on the back, sides, limbs, and head or neck. They appear as firm, movable, hairless lumps that may ulcerate. Complete removal or freezing cures the benign forms.
Basal Cell Tumors in Dogs and Cats
Basal cell tumors are common, usually slow-growing skin tumors of dogs and cats that arise from the basal layer of the epidermis or hair follicles. Most are benign and stay confined to the skin, though larger ones can ulcerate. Complete surgical removal is typically curative.
Canine and Feline Renal Adenoma and Kidney Tumors
Kidney tumors in dogs and cats may be primary growths such as renal adenoma or nephroblastoma, or spread from cancers elsewhere — metastatic kidney tumors are actually more common. Signs are vague but include weight loss, abdominal swelling, and changes in urination.
Canine and Feline Metastatic Lung Tumor
Metastatic lung tumors are cancers that have spread to the lungs from a primary tumor elsewhere, such as mammary, bone, or oral melanoma. Signs resemble primary lung disease but cough is less common, and the outlook is generally poor.
My dog has a soft, dark-colored lump under its eye — what could it be?
Without a clear photo a firm diagnosis isn't possible, but a lump under the eye may be a tumor (e.g., meibomian adenoma, histiocytoma, melanoma) or a soft cyst or hematoma from injury or infection. Have a vet examine it to confirm the type.
My dog has a dark, soft lump under the eye — what could it be?
A soft lump under the eye may be a cyst or hematoma (often from a knock or infection) or, if well-defined, a growth such as a meibomian adenoma, histiocytoma, melanoma, or squamous cell carcinoma. A vet exam is needed for a firm diagnosis.
