The first case: acute abdomen due to gastric gastrointestinal stromal tumor perforation with synchronous renal cell carcinoma.

AIM: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract and they may coexist with renal cell cancers (RCC). The main treatment method of GIST and RCC is curative elective surgery. Surgery followed by oncological treatment with sunitinib is the main treatment option when these tumors coexist.

CASE REPORT: A 32-year-old male, after a traffic accident applied to the emergency department. A thoraco-abdominopelvic computed tomography was performed, which demonstrated the presence of diffuse hemorrhagic fluid in the abdomen with 11x10 cm exophytic gastric mass and 2 x 2 cm right renal mass. After emergent laparotomy with gastric wedge resection and partial nephrectomy, patient was discharged uneventfully.

CONCLUSIONS

If the patient's clinical condition is suitable for surgery, both tumors can be removed simultaneously, even in emergency situations. Thus, difficulties and complications that may occur during follow-up and the second operation can be avoided.

KEY WORDS: Acute Abdomen, Gastrointestinal Stromal Tumor, Renal Cell Carcinoma.
