A 19-year-old, female, yellow-naped Amazon parrot was presented with a 1-year history of feather picking and an incidental 14-year history of ptyalism. Coprophagy had also been observed for an unspecified length of time, and the owners were unsure if this behavior had preceded the ptyalism.
This crusting on the feathers was attributed to ptyalism. No feathers were present under the wings, and few down feathers were present on the cranial aspect of both stifles.
Because of the lack of acceptable medical treatments available for chronic ptyalism and because the lesions were multifocal, no definitive treatment was given for the sialoceles or sialoliths.
Follow-up conversation with the owners 3 weeks after the initial presentation revealed that both the feather picking and the ptyalism had ceased.
Animals with sialoceles may be asymptomatic or present with ptyalism, dysphagia, or, rarely, dyspnea.
Because the patient's ptyalism was not especially troubling to either the patient or the owners, surgical resection was impractical.
