A 74-year-old man visited our hospital with a huge, palpableiver tumor. A T1-weighted axial MRI demonstrated a heteroge-eous tumor in the right hepatic lobe (Fig. 1). 19 years ago theatient had undergone a total gastrectomy for the bulky gastricubmucosal tumor (SMT) > 10 cm in size. The pathologic diagnosisas labeled as leiomyosarcoma. A hepatectomy was performed,nd the patient regained his health with no indication of recurrence4 months.The lesional hepatic tissue showed spindle cells arranged in
n interlacing fascicular growth-pattern reminiscent of the fea-ures observed in the prior gastric LMS. Further examination of-kit yielded positive immune staining in both tumors (Fig. 2).enetic analysis in each lesion revealed the same in-flame dele-
