title: Malignant neoplasia in four alpacas.
abstract: Malignant neoplasia in 4 alpacas was characterized by acute onset of clinical signs and rapidly deteriorating condition. Postmortem examination revealed metastatic or multicentric neoplasia in the abdominal organs of alpacas 1, 3, and 4 and an extensive thoracic mass in alpaca 2. Immunohistochemical stains supported a diagnosis of B-cell lymphosarcoma in alpacas 1-3 and a neuroendocrine neoplasm in alpaca 4.
