Nasal squamous cell carcinoma in a cow

A patient with a turgid, hemorrhagic mass infected by myiasis in the left nostril and diagnosed as squamous cell carcinoma (SCC) is presented. Complete blood count (CBC) showed moderate neutrophilia and eosinophilia and vital signs were in normal range. After aseptic surgical preparations and local anesthesia, the mass removed en bloc and submitted to the Department of Veterinary Pathology for histopathological evaluation. SCC was recognized microscopically by identifying malignant epithelial cells demonstrating various degrees of differentiation towards keratinocytes.
