Coexistence of small gastrointestinal stromal tumor and pancreatic cancer: A case report and literature review

Small gastrointestinal stromal tumors (GISTs) are rare and malignant tumors that originate in the mesenchymal tissue. Due to their insidious onset and nonspecific symptoms, they are often misdiagnosed, and are generally detected during the diagnosis and treatment of other diseases. The present case report reviewed the treatment process of a patient with a small GIST coexisting with pancreatic cancer who was admitted to the Yiwu Central Hospital (Yiwu, China) in June 2018. The patient was diagnosed and treated comprehensively using a combined approach of urology, and gastrointestinal and hepatobiliary surgery. The present case report provides important clinical insights, which allow for an improved understanding of GIST and provides a reference for clinical treatment.
