A case of coprophagia presenting with sialadenitis.

PRESENTATION: a 94-year-old woman with dementia was admitted to an acute geriatric ward with increasing confusion and falls. On two occasions she developed submandibular masses. Faeces were aspirated from her mouth and a diagnosis made of recurrent submandibular sialadenitis secondary to coprophagia. OUTCOME: the submandibular mass settled with antibiotics and oral care. Coprophagia was not observed on the ward, but faecal smearing was noted. With regular toileting, this behaviour ceased and sialadenitis did not recur.
