Summary
This study reports the first case of intraocular extramedullary plasmacytoma in a cat, a rare plasma cell tumor in the eye. Early surgical removal may prevent metastasis of this feline ocular neoplasm.
Area of Science:
- Veterinary Ophthalmology
- Comparative Oncology
- Pathology
Background:
- Intraocular neoplasms in felines can present diagnostic challenges.
- Ocular trauma may predispose certain conditions, including tumors.
- Extramedullary plasmacytomas are rare in cats, with limited data on ocular involvement.
Observation:
- An 8-year-old Domestic Short-haired cat presented with blindness, uveitis, and an iridal mass after ocular trauma.
- Histopathology confirmed neoplastic plasma cell proliferation in the iris and excised mandibular lymph node.
- No evidence of disseminated disease was found at the time of diagnosis.
Findings:
- This case represents the first documented instance of intraocular extramedullary plasmacytoma in a feline patient.
- The tumor was localized to the iris and a regional lymph node.
- The potential for metastasis and association with systemic disease, such as multiple myeloma, remains to be elucidated.
Implications:
- Early enucleation (eye removal) is suggested as a potential strategy to prevent metastasis, analogous to trauma-associated sarcomas.
- Periodic systemic monitoring for multiple myeloma is recommended for affected cats.
- Further research is needed to understand the clinical behavior and prognosis of feline intraocular plasmacytomas.
