[Focal nodular hyperplasia of the liver with malignant endoscopy appearance]

We report the case of a male patient, 49 years of age, who was admitted to our hospital to clarify the diagnosis of a solid liver tumor of the left lobe of the liver which had been made by image methods (U.S., scan and scintigraphy). Laparoscopy showed an isolated tumor emerging from the left lobe of the liver featuring hypervascularity and umbilication at the top. A visual diagnosis of malignancy was made which was not confirmed neither by biopsy nor the cytological examination. Liver resection was undertaken, and a diagnosis of nodular hyperplasia was made by the pathologist. We have never encountered before this endoscopic appearance of focal nodular hyperplasia either in our own experience or in the search of the literature.
