Summary
A canine presented with skin nodules and testicular enlargement. Diagnosis confirmed malignant seminoma, which unfortunately led to systemic metastasis and death despite chemotherapy.
Area of Science:
- Veterinary Oncology
- Canine Pathology
Background:
- Seminomas are germ cell tumors that can occur in male dogs.
- Cutaneous and testicular tumors require accurate histopathological diagnosis.
Observation:
- A three-year-old crossbred dog exhibited multiple dorsal cutaneous nodules.
- Unilateral testicular enlargement was noted.
- Skin lesions and testicular tissue were biopsied for examination.
Findings:
- Histopathology revealed malignant seminoma in both skin and testicular tissues.
- The tumor demonstrated aggressive behavior with widespread metastasis.
Implications:
- This case highlights the potential for seminomas to metastasize systemically in dogs.
- Early detection and aggressive treatment are crucial for managing canine seminomas.
- Further research into effective adjuvant therapies for metastatic seminoma is warranted.
