Primary hepatic gastrointestinal stromal tumor: A case series

Asian J Surg. 2021 Oct 9:S1015-9584(21)00576-5. doi: 10.1016/j.asjsur.2021.09.003. Online ahead of print.ABSTRACTThe liver is the most common metastasis site of gastrointestinal stromal tumours (GISTs). However, primary hepatic gastrointestinal stromal tumours (PHGISTs) are also reported, which is no more than 40 cases to date. PHGISTs are mostly misdiagnosed preoperatively due to the lack of specific symptoms and imaging features. It majorly attributes to vague characteristics on CT or MRI, which PHGISTs almost meet the imaging diagnosis criteria of hepatocellular carcinoma (HCC) or hepatapostema. Here we reported an educational case series of PHGISTs with misleading medical histories and imaging features. Case 1: The patient has a history of Hepatitis B, which lead to the misuse of The Liver Imaging and Reporting Data System (LI-RADS) classification on CT. The hepatic occupying lesion was estimated as LR-5 which meant the definite diagnosis of HCC. Unexpectedly, the postoperative pathology demonstrates PHGISTs; Case 2: Another patient, who manifested hepatalgia and fever, was misdiagnosed as hepatapostema according to CT, which lead to the operation of ultrasound-guided percutaneous catheter drainage. Case 3: A female farmer living in a schistosomiasis-infested area was hospitalized for an asymptomatic hepatic mass. Diagnosis of HCC was considered for high-risk factors and radiography features. Postoperative did verify the existence of old eggs of schistosomiasis, but the t...
