Lipoma of the liver: a differential-diagnostic problem

Background And Aims:
Lipomatous tumors of the liver are extremely rare; most of them are found incidentally at autopsy. Appropriate methods of the diagnosis of these lesions are ultrasonography (US), computed tomography (CT) and biopsy.
Case Report:
The case of a 65-year-old man who had undergone an upper-rectum resection because of exulcerated adenocarcinoma of the rectum is described. Six months later, routine control examination revealed a solid tumor in the left lobe of the liver. The tumor was not demonstrated by either sonography or CT before the operation. Repeated US, CT scan and fine-needle biopsy could not exclude the possibility of a metastatic tumor secondary to previous malignancy. The lesion was removed by wedge resection and was proven to be a lipoma.
Conclusion:
Despite adequate preoperative examination (CT, biopsy and US), an anamnestic adenocarcinoma of the rectum can lead to inappropriate therapy. The inadequate result of our therapeutic policy can be explained by the extremely rare incidence of lipoma of the liver.
