Diagnosis and management of a peripheral T-cell lymphoproliferative disease in an American pine marten (Martes americana)
A 9-year-old neutered male American pine marten (Martes americana) was referred for further evaluation of suspected lymphoproliferative disease. On physical examination, the pine marten was determined to be in an underconditioned state with an enlarged right mandibular lymph node. Hematology reveale...
