title: Ovine nasal adenopapilloma: incidence and clinicopathologic studies.
abstract: Nasal adenopapillomas were observed in 9 Y'anKasa and 1 Y'anKasa-Suffolk crossbred sheep (8 females and 2 males) over a 20-month period. The neoplasms originated from the epithelium of the lateral mass of the ethmoid bone. Gross and histologic features and clinical signs were similar in all cases. Influence of sex, age, or genetics was not established.
