Multicentricity of gastrointestinal stromal tumors (GISTs) has been described only in patients with neurofibromatosis type 1 (NF1) or within the small intestine, and different pathogenetic mechanisms are involved. We report a case of synchronous sporadic gastric and jejunal GISTs, which were resected laparoscopically in a 67-year-old man. Immunohistochemical analysis revealed that both lesions were KIT (CD117)-positive, but that the gastric lesion was CD34-positive, whereas the jejunal one was Vimentin-, S-100-, and SMA-positive. Molecular analysis of mutations in KIT exons 9, 11, 13, and 17, and in PDGFRA exons 12 and 18 revealed the presence of a gastric sporadic GIST with a KIT mutation of the exon 11 and a jejunal sporadic GIST without KIT or PDGFRA mutations. To our knowledge, this is the first report of laparoscopically resected synchronous sporadic gastric and jejunal GISTs.
