Given the age distribution of ocurrence, a diagnosis of GISTs during pregnancy or puerperium is very uncommon. A 26-year-old primigravid woman was admitted to our emergency department with labor pain. During cesarean a 7 cm mass was found incidentally, which originated from the antimesenteric wall of the small intestine. The patient underwent a small bowel resection and partial omentectomy on the 38th day after cesarean section by the general surgical team. Pathology revealed a 9x6x6 cm infiltrative gastrointestinal stromal tumor. Imatinib therapy was started with medical oncology’s recommendation. The patient is still being followed by the medical oncology clinic. In conclusion, exploration of the abdomen during a cesarean section is important for the detection of asymptomatic masses.
