Summary
This study details equine cutaneous schwannomas, rare skin tumors in horses. These tumors showed benign behavior and were successfully treated with surgical excision, offering a good prognosis.
Area of Science:
- Veterinary Pathology
- Equine Oncology
- S100 Protein Immunohistochemistry
Background:
- Schwannomas are rarely documented in equine populations.
- Understanding these tumors is crucial for accurate diagnosis and treatment in horses.
Purpose of the Study:
- To describe the clinicopathological features of cutaneous schwannomas in horses.
- To evaluate the immunohistochemical profile and clinical behavior of these equine tumors.
Main Methods:
- Histopathological examination of 22 equine cutaneous schwannoma cases.
- Immunohistochemistry for S100 protein, laminin, and glial fibrillary acidic protein.
- Ultrastructural analysis of one tumor specimen.
Main Results:
- 22 horses aged 8-25 years presented with solitary cutaneous masses.
- Tumors exhibited features of Antoni A and Antoni B areas, with S100 protein positivity in all cases.
- Surgical excision was curative in 9 horses with long-term follow-up, indicating benign behavior.
Conclusions:
- Equine cutaneous schwannomas share microscopic similarities with human schwannomas.
- These tumors demonstrate benign clinical behavior and are curable by surgical excision.
- Accurate classification aids in prognosis and treatment planning for equine cutaneous schwannomas.
