An elderly Asian man returned from Bangladesh with an 18-month history of intermittent hiccoughs, anorexia, weight loss and fever. He had type 2 diabetes on insulin therapy with deteriorating glycaemic control. Examination revealed a thin, pale man, with intermittent hiccoughs, darkening of palmar creases and mucous membranes, angular stomatitis, oral ulceration and mild epigastric tenderness. He appeared clinically dry. He was noted to have a spiking fever to 38.5ЊC and became notably hypotensive with a blood pressure 82/35 mm/Hg during his admission. Initial investigations are shown in Table 1. Chest radiography was unremarkable and an abdominal ultrasound noted a 13.5 cm splenomegaly. There was no evidence for a subphrenic abscess.
