Solitary Tuberculoma of the Liver Concomitantly Found in a Pancreatic Cancer Patient

A case of solitary tuberculoma of the liver is presented with a review of 25 cases reported in the Japanese literature. The patient was 77 years old. The serum CA19-9 level was elevated during a follow-up observation after surgery for sigmoid colon cancer. Abdominal CT, ultrasonography, ERCP and hepatic angiography revealed pancreatic body cancer and metastasis in S6 of the liver. Distal pancreatectomy and hepatic resection of S6 was performed. Pathological examination of the resected specimen of the liver disclosed tuberculoma composed of epitheloid cells and lymphocytes with caseous necrosis. Although solitary tuberculoma of the liver is rare, it should be included in the differential diagnosis of liver tumor.
