Abstract

One of your more regular clients presents to you a cockatiel which was purchased six months ago. The owner describes a two week history of dysphagia, anorexia, loss of weight and a general loss of activity. Upon physical examination the most outstanding lesions consisted of white, moderately raised areas of well circumscribed nodules and fibronecrotic plaques in the oral cavity.</p>
