Tumors

  • Plasma cells (plasmacytes) are specialized cells that function as part of the body’s immune system. They are formed from ‘B’- type lymphocytes.

  • The definition of a pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.

  • The prostate gland stores sperm from the testicles and produces fluid that contains essential nutrients for the sperm. Cancers of the prostate are rare but usually involve the cells that make the fluid.

  • Common conditions of pet rabbits include snuffles, internal and external parasites, overgrown incisors, uterine problems (infections or cancer), and sore hocks.

  • Common conditions of pet rodents include respiratory diseases, anorexia and lethargy, overgrown teeth, and tumors.

  • Round cell tumors are among the most common skin tumors in dogs, and they typically form just under the skin, although they may change the surface of the skin above them. When caught early, most round cell tumors are removed easily, and surgery is generally curative. The most important take home message is to be vigilant, and to have any skin lumps or bumps assessed by your veterinarian promptly.

  • Salivary cancers are almost invariably malignant tumors originating from the secretory cells of the glands. Other swellings or tumors of salivary glands may be due to infections and cysts.

  • Equine sarcoids are the most common tumors seen and account for approximately nine out of every ten skin tumors seen in horses. They are non-malignant (i.e., they do not spread throughout the body) but do grow larger and often spread and multiply locally.

  • This tumor is a disordered and purposeless overgrowth of sweat gland cells. Most sweat glands are attached to the hair follicles (“paratrichial”, or beside the hair) but a few are not associated with follicles (atrichial).

  • This slow-growing tumor is a disordered overgrowth of cells of the epidermis, or outer layer of skin. It gets its name from its resemblance under the microscope to the basal cell layer of epithelium.
