Metastatic lipid-rich mammary carcinoma in a dog / 대한수의학회지

An adult female dog was presented for evaluation of mammary gland masses. Complete blood count and serum chemistry data were within normal limits. Fine-needle aspiration cytology of the mammary masses revealed clusters of malignant epithelial cells with clear cytoplasmic vacuoles. Based on histopathological findings, a diagnosis of lipid-rich mammary carcinoma was made. Approximately 5 weeks after surgical removal, the tumor recurred at the surgery site and metastasis to the tibia was detected. Due to the poor prognosis and deterioration of the condition, the dog was euthanized.
