A 20-year-old male captive Humboldt's white-fronted capuchin (Cebus albifrons) that died accidentally had a small non-ulcerative mammary nodule diagnosed as a mammary carcinoma. Immunohistochemistry demonstrated that neoplastic cells were positive for pan-cytokeratin and cytokeratin-7. Approximately 20% of neoplastic cells were positive for Ki-67. Neoplastic cells expressed estrogen and progesterone receptors.
