Overview

Case report describes aggressive primary mammary SCC with metastases, suggesting unique behavior in sheep.

Key Points

  • The study aims to report an unusual case of primary mammary squamous cell carcinoma (SCC) with widespread metastases in a ewe.
  • Examination of a 3.5-year-old ewe with a history of chronic mastitis and euthanasia post-surgery.
  • Surgical removal of the udder and subsequent histological analysis of tissues.
  • Evaluation of immunohistochemical markers in neoplastic cells.
  • Histological examination revealed neoplastic squamous cells with keratinized cores and extensive necrosis.
  • Metastatic nodules were found in lymph nodes, peritoneum, lungs, and heart.
  • Immunohistochemical labeling confirmed epithelial origin of neoplastic cells, indicating a primary mammary source.
