Lymphoma

Renal lymphoma produces CKD-like symptoms (poor appetite, excessive thirst, weight loss) and can directly damage kidney tissue.

Cutaneous lymphoma is one of the anatomic forms

Common trigger in cats

— FeLV is a major cause; vaccination changed predominant lymphoma form

Most common cause of hypercalcemia in dogs (via PTH-rP)

Low-grade intestinal lymphoma behaves like severe IBD and treatment is similar.

— differential for subcutaneous lumps

— differential diagnosis

Lymphoma relies on this process to progress from localized nodes to systemic disease.

Oral lymphosarcoma is one type of oral cancer

One of several anatomical forms of feline lymphoma.

Diarrhea is a frequent sign of intestinal lymphoma.

Swollen and hardened lymph nodes are the hallmark physical presentation of this malignancy.

Nasal lymphoma can cause epistaxis

Mediastinal lymphoma is the primary cause in cats.

Variable appetite in lymphoma, also seen in advanced CKD.

Common in intestinal lymphoma, also seen in CKD and hyperthyroidism.

Shared symptom across intestinal, renal, and other lymphoma forms, and across CKD and hyperthyroidism.

Chemotherapy is the standard treatment for all forms.

Specifically addresses relapsed or refractory lymphoma cases.

Part of the standard treatment for low-grade intestinal form.

Highly effective against lymphoid malignancies in dogs and cats.

Key oral medication for low-grade intestinal lymphoma.

Provides symptomatic relief and direct anti-lymphoma activity.

Definitive diagnosis requires tissue confirmation.

Blood work may reveal secondary organ changes.

Staging is a critical diagnostic step for determining the extent of lymphoma spread.

Key diagnostic tool for intestinal lymphoma.

This system provides the anatomical pathway and cellular origin for lymphoma development.
