Lymphosarcoma, a form of lymphatic leukemia, is one of the most common malignant diseases seen in the feline species. It is not a true lymphatic leukemia, but can rarely be differentiated from such histologically. Leukemia is defined as a cytologically distinct malignant disease of lymphoid or heamatopoietic cell lines and tissues.
