[Anicteric cholestasis: a rare hepatic dysfunction caused by hyperthyroidism].

Clinical manifestations and visceral involvements described in patients with thyroid disease are many and varied. However, cases of patients with hepatic manifestations have been rarely reported in the literature. We here report the case of a 50 year old patient diagnosed with Graves' disease without a goiter or ocular manifestations. Follow-up laboratory testing led to the detection of anicteric cholestasis. Investigations of the potential causes were negative and given the normalization of the liver parameters after appropriate treatment of hyperthyroidism, the diagnosis of hepatic involvement secondary to Graves' disease was retained. The purpose of this study was to report a new case of rare hepatic manifestation (cholestasis anictérique) in a patient with hyperthyroidism: Graves' disease.
