Malakoplakia in a Transplanted Liver

Abstract

ABSTRACT Malakoplakia is a rare acquired histiocytic disorder first described in the urinary bladder. There have been 8 cases reported involving the liver, and this is the first reported case of malakoplakia involving an adult transplanted liver. We report a 63-year-old man with a medical history of orthotopic liver transplantation who presented with fever, chills, and abdominal pain. Imaging found confluent microabscesses in the right lobe of the liver that persisted despite prolonged antibiotics. He was taken to the operating room for a segment 6 hepatectomy of the abscess. Histologically, the inflammatory process showed malakoplakia.
