Summary

Insulinoma is a rare tumour that is malignant in only 10% of cases. We report a case of insulinoma in a 59-year-old woman, associated with focal liver lesions, which raised the suspicion of malignancy of a pancreatic tumour. Enucleation of the insulinoma was performed with wedge resection of one hepatic nodule. Pathological examination indicated that the pancreatic tumour was compatible with insulinoma whereas the hepatic lesion was related to focal nodular hyperplasia. This clinical case highlights the need for histopathological proof of malignancy before selecting therapeutic strategies for insulinomas.
