A Holstein cow diagnosed with ocular lymphangiosarcoma, a rare vascular tumor, showed no recurrence after surgical removal. This case highlights a rare veterinary cancer diagnosis and successful treatment outcome.

Area of Science:

Veterinary Oncology
Ophthalmology
Neoplastic Disease Research

Background:

Lymphangiosarcoma, a rare vascular neoplasm, has limited reporting in domestic animal species.
Ocular tumors in cattle can present diagnostic and therapeutic challenges.
Understanding rare cancer presentations is crucial for veterinary medicine.

Observation:

A Holstein cow presented with a progressively enlarging limbal mass, indicative of ocular neoplasia.
Diagnostic evaluation confirmed the mass as lymphangiosarcoma, a vascular tumor.
The tumor was located at the limbus, the border between the cornea and sclera.

Findings:

Surgical treatment via exenteration was performed to remove the ocular tumor.
The cow experienced a disease-free survival of 2 years post-exenteration.

No clinical signs of tumor recurrence were observed during the follow-up period.

Implications:

This case demonstrates that ocular lymphangiosarcoma, despite its rarity and typically poor prognosis in other species, can be successfully managed in cattle.
Complete surgical excision may offer a favorable long-term outcome for ocular lymphangiosarcoma in cows.
Further research into the biology and treatment of lymphangiosarcoma in animals is warranted.
