[Painless jaundice after holidays in Tanzania].

The side effects caused by malaria prophylaxis with mefloquine (Lariam) are well known. We describe the case of a 42-year-old female Caucasian patient suffering from painless jaundice and showing elevated liver, cholestasis and inflammation laboratory findings 7 days after returning from Tanzania. Acute cholecystitis was diagnosed by ultrasound. Treatment with parenteral nutrition and antibiotic therapy did not show any beneficial effect. Excluding the possibility of infectious diseases, the elevated laboratory and ultrasound findings were normalized after the discontinuation of the malaria prophylaxis.
