Lymphatic tumors are rare in pets. Lymphangiomas are benign and lymphangiosarcomas are malignant and have a moderate-to-high metastatic potential. Patients with lymphatic tumors typically have severe edema or cavity effusions because of lymphatic obstruction and leakage. These types of tumors occur more frequently in young dogs and cats. Treatment usually involves surgical excision and chemotherapy may be used as a follow-up treatment in the case of lymphangiosarcomas.

Lymphocytic plasmacytic gastroenteritis is a form of inflammatory bowel disease. While the exact cause is not known, it is possible that the intestinal bacteria themselves may be involved in stimulating the immune response. Signs include diarrhea, vomiting, loss of appetite, weight loss, and blood in the stool/vomit. Treatment may include nutrition management, immunosuppressive medications, and dietary supplementation of cobalamin, prebiotics, and probiotics.

Lymphoma is a cancer of the lymphocytes, which are cells involved in the immune system. These cells travel throughout the body, so lymphoma may affect one area or several parts. Vaccination for feline leukemia virus infection (FeLV) can reduce the likelihood of lymphoma in cats.

Lymphoma is a cancer of the lymphocytes, which are cells involved in the immune system. These cells travel throughout the body, so lymphoma may affect one area or several parts. Lymphoma is relatively common in dogs. There are four main types, and the prognosis varies depending on the type.

The most common forms of cutaneous lymphoma are epitheliotropic lymphoma and dermal lymphoma. No specific risk factors or causes have been identified in the development of cutaneous lymphoma. Generally, cutaneous lymphoma can appear as various-sized irritated, ulcerated, or infected patches anywhere on the skin, including the gums, nose, or lip margins. These areas may become ulcerated and bleed, or become crusted. Secondary infections are possible. By far, the most common treatment for cutaneous lymphoma is chemotherapy. Unfortunately, the response to treatment, although initially encouraging, is typically short-lived, with gradual return of the tumors.

Ferrets can suffer from tumors in any part of their body, ranging from benign cancers of the skin to aggressive malignant tumors of internal organs. The clinical signs depend on the type of tumor, the organ involved, and the stage of the disease. For a dedicated owner with an otherwise healthy-looking patient, treatment with chemotherapy is a very good option.

Lysine (brand names: Enisyl-F, Incremin, Viralys, Felisyl, Optixcare) is an amino acid supplement used to treat clinical signs associated with feline herpes virus infection in cats.

Lysosomal storage diseases are a rare collection of inherited conditions. Many are more prevalent in certain breeds and are seen in the first few months of life. Clinical signs vary, but commonly include failure to thrive, incoordination, vision loss, and seizure. Prognosis is usually poor for long-term survival.

Macadamia nuts are edible for humans, but even a few nuts are poisonous for dogs. They can also result in pancreatitis, due to their high fat content. This handout outlines signs, treatment, and prognosis for macadamia nut poisoning.
