A patient is described who developed gastrointestinal amyloidosis complicating psoriatic arthropathy. The presenting symptom was progressive dysphagia due to oesophageal involvement. Other clinical features included gastric ulceration with melaena, intestinal pseudo-obstruction and evidence of impaired renal function. The oesophageal symptoms improved after endoscopic dilatation of the cardia. Colchicine was used in an attempt to slow down progression of the condition.
