Transitional cell carcinoma in a cat

Area of Science:

  • Veterinary Urology
  • Surgical Oncology
  • Feline Neoplasia

Background:

  • Dysuria in cats can indicate serious underlying conditions.
  • Urethral masses are rare but challenging diagnoses in veterinary medicine.
  • Transitional cell carcinoma (TCC) is an aggressive cancer affecting urinary tract tissues.

Observation:

  • A 15-year-old male neutered cat presented with dysuria.
  • Retrograde urethrography revealed two urethral masses.
  • Exploratory surgery confirmed urethral masses requiring resection.

Findings:

  • Histopathology diagnosed the urethral masses as transitional cell carcinoma (TCC).
  • Surgical resection via segmental urethrectomy was performed, followed by vesico-urethral anastomosis.

  • Incomplete surgical margins and tumor regrowth were noted approximately 318 days post-surgery, managed with palliative radiation therapy.

    • Implications:

    • This case highlights the importance of thorough diagnostic workups for feline dysuria.
    • Transitional cell carcinoma presents a significant challenge in feline urethral oncology.
    • Palliative radiation therapy may offer clinical sign management for recurrent urethral TCC in cats.
