Rotor syndrome

Rotor syndrome is a rare, benign autosomal recessive disorder of unknown origin.

Presentation
It has many things in common with Dubin-Johnson syndrome except that in Rotor Syndrome, the liver cells are not pigmented. The main symptom is a non-itching jaundice. There is a rise in bilirubin in the patient's serum, mainly of the conjugated type.

Treatment
The liver is otherwise normal, and there is no need to treat this condition. It can be differentiated from Dubin Johnson syndrome by measuring the difference in urinary poryphrins. In Rotor syndrome there is an associated marked increase in urinary excretion of coproporyhrin I and III with < 80% being the I isomer.

Eponym
Rotor syndrome is named after the Filipino internist, Arturo Belleza Rotor (1907-1988).
