[Clinical and pathological features of Dubin-Johnson syndrome].

To explore the clinical and pathological features of Dubin-Johnson syndrome. The clinical and pathological characteristics of 18 cases of Dubin-Johnson syndrome diagnosed in the Department of Pathology of the Third Affiliated Hospital of Sun Yat-sen University from 2008 to 2018 were analyzed. Related literature was reviewed. There were 15 male and three female patients. The male-to-female ratio was 5∶1. The age of the patients ranged from 17 to 73 years (median 24 years). Common clinical manifestations were jaundice, anorexia, and abnormal liver function tests. The pathological feature was the deposition of dark brown particles in the hepatocytes, especially those around the central veins. Dubin-Johnson syndrome mainly occurs in young people. The characteristic pathological changes are the deposition of dark brown particles in the hepatocytes around the central veins of the liver. The diagnosis of Dubin-Johnson syndrome mainly relies on clinical manifestations, laboratory examinations, histopathological examinations and genetic testing. The understanding of Dubin-Johnson syndrome can help reduce the rates of missed diagnosis and misdiagnosis of the disease.
