Highlights • First report of synchronous incidental gallbladder adenocarcinoma and gastric GIST. • Incidental diagnosis of gallbladder cancer with GIST diagnosed during staging. • Patient is under adjuvant treatment and after 16months has no signs of recurrence., Introduction Synchronous occurrence of different types of neoplasms is not very frequent, representing around 6% of all cases of cancer. Usually there is a lack of information on how to treat these patients, especially when both types of cancers are also uncommon. No cases of synchronous gallbladder adenocarcinoma and gastric gastrointestinal stromal tumor have been published before. Presentation of case We present the case, management and follow-up, of a 66-year-old female with incidental diagnosis of a pT2NxMx gallbladder adenocarcinoma after elective cholecystectomy that latter, during staging, was also diagnosed with GIST. Total gastrectomy, wedge resection of the liver and lymphadenectomy were performed due to the new findings. Adjuvant chemotherapy for 36 months was indicated. After 16 months of the treatment she has no signs of recurrence. Discussion Gastrointestinal stromal tumors (GISTs) had a turnaround in the end of the 20th century after the introduction tyrosine-kinase inhibitor to the adjuvant treatment and now the trend is to extend it up to 36 months in selected patients. Gallbladder adenocarcinoma is an uncommon cancer but the incidental diagnosis is increasing with the popularity of laparoscopic cholecystectomy and, thus, specific management should be offered for these patients, what frequently includes a complementary surgery. Although, GISTs may be associated with another synchronous tumor in 20% of the cases, the simultaneous occurrence with gallbladder cancer is incredibly rare. Conclusion Simultaneous occurrence of gastric GIST and gallbladder adenocarcinoma has not been reported before and, thus, any information about it may help in the management of those patients.
