[Metastasizing gastrinoma and tuberous sclerosis complex. Association or coincidence?]

We report about the case of a 34-year-old male patient suffering from a combination of Bourneville-Pringle disease and a metastasizing gastrinoma. As far as we know this association has hitherto not been described in the literature. We believe that a gastrinoma could develop against the background of the general tissue dysplasia which tuberous sclerosis represents. In our opinion, gastrinomas should be included into the tuberous sclerosis complex as a new form of possible association.
