Summary
A young Oriental Shorthair cat with retropharyngeal leiomyosarcoma experienced stridor. Surgical removal led to no recurrence 7 months later, presenting a rare feline cancer case.
Area of Science:
- Veterinary Medicine
- Oncology
- Feline Neoplasia
Background:
- Leiomyosarcoma is a rare smooth muscle tumor in cats.
- Retropharyngeal tumors can cause respiratory distress.
Observation:
- A young Oriental Shorthair cat presented with progressive stridor and a cervical mass.
- Initial fine-needle aspiration was inconclusive; doxycycline and prednisolone provided temporary relief.
Findings:
- Histopathology confirmed leiomyosarcoma with incomplete margins.
- No recurrence was detected 7 months post-excision and without radiation therapy.
Implications:
- This case highlights the possibility of successful surgical management for feline retropharyngeal leiomyosarcoma.
- Early diagnosis and complete excision are crucial for favorable outcomes in feline soft tissue sarcomas.

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:51Mechanisms of Retrovirus-induced Cancers
5.2K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
