Summary
This study reports the first case of a solitary nodular cutaneous lymphoma in a young Doberman Pinscher. The T-lymphocyte cancer was successfully treated with surgery, with no recurrence observed.
Area of Science:
- Veterinary Oncology
- Dermatopathology
- Canine Neoplasia
Background:
- Cutaneous lymphoma in dogs can present in various forms.
- Early and accurate diagnosis is crucial for effective treatment and prognosis.
- T-lymphocyte lymphoma is a significant subtype of canine lymphoma.
Observation:
- An 18-month-old Doberman Pinscher presented with a solitary, erythematous, nodular skin mass on its forelimb.
- Cytologic examination and histopathology confirmed the mass as cutaneous lymphoma.
- Immunohistochemistry identified the neoplastic cells as T lymphocytes (CD3 positive, CD79a negative).
Findings:
- The canine cutaneous lymphoma was a solitary nodular form, originating from T lymphocytes.
- Surgical excision was performed for the mass.
- No tumor recurrence was observed 18 months post-surgery, indicating successful treatment.
Implications:
- This case highlights a rare presentation of canine cutaneous lymphoma in a young dog.
- It underscores the importance of immunohistochemistry in differentiating lymphoma subtypes.
- The successful surgical outcome suggests this may be a viable treatment option for solitary nodular forms.
