Summary
This study reports a rare feline histiocytic sarcoma in a cat. Despite amputation, the cancer recurred, leading to euthanasia, highlighting challenges in treating this aggressive tumor.
Area of Science:
- Veterinary Medicine
- Oncology
- Dermatology
Background:
- Histiocytic sarcoma is an uncommon and aggressive tumor in cats.
- Cutaneous manifestations can be the primary presentation of histiocytic sarcoma.
- Treatment options and outcomes for feline histiocytic sarcoma are not well-established.
Observation:
- A 9-year-old domestic shorthair cat presented with a tarsal skin lesion.
- Histopathological and immunohistochemical analysis confirmed histiocytic sarcoma.
- Surgical amputation of the affected limb was performed.
Findings:
- Postoperative improvement was noted, but skin lesions recurred within 44–60 days.
- Relapse occurred at multiple sites, including the amputation site.
- Euthanasia was elected due to disease progression.
Implications:
- This case is the first report of feline histiocytic sarcoma treated with amputation.
- Amputation alone may not be sufficient for managing feline histiocytic sarcoma.
- Highlights the need for understanding the aggressive behavior and exploring alternative therapies for this rare feline cancer.
