Primary gastrointestinal stromal tumor of the liver: a case report

Introduction and importance:Primary gastrointestinal stromal tumors of the liver are exceedingly rare entities, presenting diagnostic and therapeutic challenges. The authors present a case of a 64-year-old male with a primary gastrointestinal stromal tumor (GIST) of the liver, emphasizing the importance of comprehensive diagnostic evaluation and multidisciplinary management in such uncommon cases.Case presentation:The patient presented with persistent hypochondriac pain, leading to the discovery of a hepatic mass. Diagnostic work-ups, including imaging studies and biopsy, confirmed the diagnosis of primary GIST in the liver. Following thorough multidisciplinary consultation, the patient underwent right anterior segmentectomy of the liver, performed by our experienced surgeon. Postoperative pathology confirmed the diagnosis of GIST, and the patient was advised to use adjuvant imatinib.Clinical discussion:Primary GISTs of the liver pose diagnostic challenges due to their rarity and varied clinical presentations. Imaging modalities, immunohistochemistry, and molecular genotyping are crucial in accurate diagnosis and treatment planning. Surgical resection remains the cornerstone of treatment for localized GISTs, with adjuvant therapy considered based on recurrence risk factors and molecular characteristics.Conclusion:This case highlights the need for multidisciplinary consultation in managing primary GISTs of the liver. Accurate diagnosis, surgical expertise, and personalized adjuvant therapy are crucial for better patient outcomes. Further research is necessary to enhance our understanding of prognostic factors and treatment strategies for these rare tumors.
