The solitary necrotic nodule of the liver is an uncommon nonmalignant lesion with an uncertain etiology. The lesion was defined as a nodule with a completely necrotic core and fibrous capsule etc. and without a consistency of viable cells. The characteristic features of this benign lesion on the imaging modalities are similar to the metastatic tumor. In this paper we discuss the case of a rapid-growing solitary necrotic nodule of the liver occurring in a patient with chronic renal failure on hemodialysis. The lesion located on the left median lobe of the liver had rapidly enlarged in diameter in the last seven months. Despite some examinations by imaging modalities to confirm the preoperative diagnosis, we were unable to visually confirm. Several histological examinations using a needle biopsy specimen were performed, but the diagnosis was all necrotic tissue. However, we recommended an extended left hepatic lobectomy for this rapid-growing lesion since cholangiocarcinoma with necrosis could be hardly differentiated. Permanent histology revealed that the lesion was solitary necrotic nodule. We consider that permanent histology of the entire lesion is possibly the only accurate method of diagnosis. Since the solitary necrotic nodule does not indicate malignancy, hepatic resection should be performed. J. Med. Invest. 53: 325-329, August, 2006
