Chronic diarrhoea in tropical countries may be due to a
myriad of causes from infective to non-infective. This case
report illustrates the challenges faced in the investigation of
a middle-age Chinese gentleman who presented with
chronic diarrhoea and weight loss. The diagnosis of type II
enteropathy-associated T-cell lymphoma (EATL) was finally
made. The diagnosis of EATL was least suspected as the
condition is almost unheard of in this part of the world. The
epidemiology, presentation, diagnosis, management and
prognosis of this rare condition are discussed.
