HEMANGIOSARCOMA IN RED WOLVES (CANIS RUFUS) AND GRAY WOLVES (CANIS LUPUS) IN HUMAN CARE: SIX CASES.
Wolves are commonly housed in zoological institutions and captive breeding facilities that are essential for maintaining genetic diversity and for the recovery of declining populations. Neoplasia is a common cause of mortality in wolves, but hemangiosarcoma has not previously been described. This condition was diagnosed in four red wolves (Canis rufus) and two gray wolves (Canis lupus) housed at five different institutions between 2008 and 2018. Animals were 11-16 yr of age at the time of presentation. Clinical signs included loss of body condition, abdominal distension, lethargy, weakness, ataxia, and hyporexia. Three animals were mildly anemic. All animals were humanely euthanized within an average of 3 d from onset of clinical signs. Two animals had primary splenic tumors, two had pelvic tumors with one originating from the aorta, and one had a cranial mediastinal mass. Diagnosis was made on postmortem histologic examination in all cases. Four wolves had evidence of metastases with foci in the lungs, lymph nodes, mesentery, liver, subcutis/skeletal muscle, kidney, adrenal, and thyroid gland. Hemangiosarcoma should be considered in geriatric wolves presenting with nonspecific signs, particularly if abdominal distension, free peritoneal fluid, or anemia is present.
期刊介绍:
The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers.
The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution.
Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
