Dubin-Johnson syndrome (DJS) is a rare autosomal recessive inheritance disorder of
bilirubin metabolism. Herein we reported a complicated but interesting case which is readily resulted in misdiagnosis or an indefinite diagnosis, and this is the first reported familial case of DJS with multiple liver
cavernous hemangiomas. A 49-year-old man was referred to our hospital for
jaundice and multiple low-density liver masses. Extensive laboratory investigations showed conjugated hyperbilirubinaemia and positive urine
bilirubin. Microscopically, lesions were composed of blood-filled vascular channels of various sizes lined by a single layer of flat endothelial cells supported by fibrous tissue. Coarse brown granules presented in the hepatocytes of the liver lobules locating beside the
tumor, particularly in the centrilobular hepatocytes, and the granules showed blue-green with Schmorl's reaction
lipofuscin staining. Interestingly, one of the patient's six siblings (female) shared the same condition with him. The relationship between DJS and
hemangiomas remains unclear, and it might be contributed to some hereditary factors, or probably occurred simultaneously by chance. It was certified that the true reason for the long-term unclear
jaundice was DJS, which was presumed clinically to be caused by bile excretion obstacles associated with the
hemangiomas. Liver biopsy and histochemical
stain may be helpful to identify the reason of
jaundice and avoid misdiagnosis or an indefinite diagnosis.
