Benign recurrent intrahepatic cholestasis is characterized by attacks of cholestasis. The purpose of our study of 26 patients was to emphasize some features uncommonly or never reported in this disease: (a) in each patient, the attacks of cholestasis were stereotypic; (b) attacks of cholestasis were not associated with pruritus in 15% of our patients; (c) the occurrence of attacks of cholestasis during pregnancy or oral contraceptive use might be a fortuitous coincidence; (d) gallstones were found in several patients with benign recurrent intrahepatic cholestasis and might be present earlier than in the general population; (e) in some of our patients, during attacks of cholestasis, serum transaminases were very high, exceeding 15 times the upper limit of normal; (f) mild portal inflammatory infiltration was found in one third of our patients; (g) no treatment shortened the duration of cholestasis, and in a few patients, plasmapheresis seemed to diminish jaundice and improve biochemical disorders
