Summary
This study details three equine gastric squamous cell carcinoma cases. Diagnosis involved clinical signs, bloodwork, and cytology, revealing abdominal metastasis.
Area of Science:
- Veterinary Oncology
- Equine Medicine
- Comparative Pathology
Background:
- Gastric squamous cell carcinoma is a rare malignancy in horses.
- Understanding its presentation and metastatic patterns is crucial for diagnosis and treatment.
Observation:
- Three horses presented with weight loss, anorexia, and lethargy.
- One horse exhibited prominent respiratory signs.
- Biopsies revealed neoplasms originating from the esophageal region of the stomach.
Findings:
- All horses had altered protein levels (low albumin, high globulin and fibrinogen) and inflammatory exudates.
- Cytology confirmed squamous cell carcinoma in two cases.
- Metastasis was observed throughout the abdomen in all cases, with two cases showing pleural metastasis.
Implications:
- This highlights the importance of considering gastric squamous cell carcinoma in horses with relevant clinical signs and clinicopathological changes.
- Early detection and understanding metastatic potential are key for improving outcomes in equine oncology.
- Further research into the etiology and treatment of this condition is warranted.
