Surgical Management of a Nasal Adenocarcinoma in an Olive Baboon (Papio cynanocephalus)
Additional Document Info
To our knowledge, this is the first report of an adenocarcinoma in the nasal cavity of an adult male baboon. Rhinoscopy and examination of an endoscopically obtained biopsy specimen revealed a nonencapsulated, noncircumscribed mass with necrotic margins. Histopathologically, small multiple lobules (acinar-like) were separated by thin fibrovascular tissue. There was neutrophilic infiltration, multifocal hemorrhage, and few mitotic figures. Because the mass was causing respiratory distress to the baboon, complete surgical resection and curettage was performed. The tumor had not recurred by 2 years after surgery.
