A Yorkshire boar diagnosed with multicentric lymphosarcoma, a type of cancer affecting T-cells. This cancer presented as multiple tumor masses and nodules throughout the boar's internal organs.

Area of Science:

  • Veterinary Pathology
  • Oncology

Background:

  • Lymphosarcoma is a significant neoplastic disease in animals.
  • Understanding the origin and spread of lymphosarcoma is crucial for diagnosis and treatment.

Observation:

  • A 14-month-old Yorkshire boar presented with abdominal tumor masses in the intestines.
  • Disseminated pale nodules were observed in multiple organs including the liver, kidneys, spleen, heart, and testicles.

Findings:

  • Immunohistochemistry revealed tumor cells positive for CD3, a T-cell marker.
  • Tumor cells were negative for B-lymphocyte markers (B-lymphocyte antigen and CD79).
  • Diagnosis of multicentric lymphosarcoma, likely of T-cell origin, was confirmed.

Implications:

  • This case highlights the potential for aggressive, multicentric lymphosarcoma in swine.
  • Immunohistochemical markers are essential for determining the cell lineage in animal lymphosarcoma.
  • Further research into T-cell lymphosarcoma in boars may improve diagnostic and therapeutic strategies.
