Abstract

Background: A captive adult male saddleback tamarin, Saguinus fuscicollis, was lethargic, unresponsive to its surrounding and died before medical care.

Methods: Necroscopic, histopathological and immunohistochemical examinations were performed.

Results: Neoplastic spindle cells of the urinary bladder were positive for antifactor VIII antibody.

Conclusion: A primary urinary bladder haemangiosarcoma was diagnosed, and it has not been previously reported in non-human primates.
