## Overview The peripheral form of lymphosarcoma is neoplastic enlargement of one or more external lymph nodes. Nodes are usually painless and progressively enlarge. Weight loss, anemia, and elevated globulins may accompany the node enlargement. The prefemoral node is commonly involved. Diagnosis is by cytology or biopsy. ## Causes Lymphoid neoplasia. ## Diagnosis Palpation of enlarged nodes and cytologic or histologic confirmation of a monomorphic lymphoid population. ## Treatment Corticosteroids or chemotherapy for palliation. Localized disease may be monitored if the horse remains comfortable. ## Recovery and Prognosis Guarded to poor. Some horses remain stable for a period; most eventually progress. ## Prevention None.
