Larvae in a traveller's faeces. Not always what it seems.

A 54-year-old Spanish woman sought medical advice at the outpatient clinic of our institution for diarrhoea and abdominal pain that began on her return from Cambodia and Laos ten days earlier. On examination, she had neither fever nor skin lesions. Laboratory tests showed haemoglobin, hepatic enzymes and a leucocyte count within normal range. No eosinophilia was detected. The patient was diagnosed of traveller’s diarrhoea. No antibiotic treatment was prescribed given the absence of fever. She was asked to bring three stool samples for microbiological studies over the following days.
