This manuscript describes the clinical and pathological findings associated with a unilateral horn core carcinoma in a 12- year-old, Nellore cow. Initially the cow presented a small growth within the right horn with consequent hanging of the affected horn and progressive increasein size of the mass, ultimately resulting in a large space occupying tumorous growth. Clinical laboratory evaluations revealed non-regenerative anemia; while bacteriological analyses yielded cultures of Pseudomonnas spp. and Arcanobacterium spp. Histopathology revealed the mass to be consisted predominantly of a well differentiated squamous cell carcinoma with areas of neoplastic glandular epithelium. The anatomic location of the tumor associated with the histopathological findings is consistent with horn core carcinoma of cattle.
