Case Report: Hepatic sinusoidal obstruction syndrome caused by Gynura segetum.

Hepatic sinusoidal obstruction syndrome (HSOS) is a hepatic vascular disease initiated by injury to hepatic sinusoidal endothelial cells. Its main clinical manifestations include hepatomegaly, elevated bilirubin, ascites and weight gain. The incidence of HSOS has been increasing year by year. Nevertheless, due to its non-specific clinical manifestations, limited effective diagnostic methods and imperfect relevant diagnostic criteria, it is highly likely to be misdiagnosed as other liver diseases. This study reports a case of HSOS induced by ingestion of Gynura segetum.
