UC Davis team removes osteosarcoma in 80-year-old tortoise

UC Davis clinicians are highlighting the case of Teetle, an 80-year-old California desert tortoise that underwent surgery for an osteosarcoma growing beneath his shell. According to UC Davis, exotic animal specialists and soft tissue surgeons used CT imaging to diagnose the mass and then developed a novel surgical approach that involved removing part of the upper shell, rather than disrupting the lower shell and the musculature supporting the hind limbs and vertebral column. The school says Teetle is recovering at home and has shown improved energy since surgery. (magazine.vetmed.ucdavis.edu)

Why it matters: For veterinary professionals, the case is a reminder that advanced imaging, cross-service collaboration, and species-specific surgical planning can expand what’s possible in exotic animal care. Tortoise shell surgery is uniquely challenging because the shell is living bone integrated with major musculoskeletal structures, and UC Davis’ account suggests careful approach selection can reduce morbidity while still allowing oncologic access. The case also underscores the growing expectations of pet parents for specialty care in reptiles and other non-traditional species. (magazine.vetmed.ucdavis.edu)

What to watch: Whether UC Davis or the clinicians involved publish a formal case report with longer-term oncologic follow-up, surgical technique details, and recurrence outcomes. (magazine.vetmed.ucdavis.edu)
