Gastrointestinal stromal tumors (GISTs) originate from the gastrointestinal tract. GISTs originate outside the gastrointestinal tract, referred to as extra GISTs, which is rare. Primary liver gastrointestinal stromal tumor (PLGIST) and liver metastasis of gastrointestinal stromal tumor (LMGIST) may present isolated liver lesion, making it difficult to determine their origin. A 38‐year‐old man who presented with isolated multiple giant cystic‐solid liver lesions, ultimately diagnosed as liver GIST through CT‐guided fine‐needle aspiration. However, distinguishing between PLGIST and LMGIST in this case is challenging due to the absence of detailed medical records of emergency small intestine resection 5 years ago. Over 2‐year follow‐up period, the maximum lesion size increased from 16 to 21 cm, still, no extra liver lesions were observed. This study aims to provide a review to enhance understanding of this rare liver entity, aiding in tumor diagnosis and staging.
