Gastric leiomyoblastoma with metastases to the liver. A 36-year follow-up study.
A patient presented with large intrahepatic tumoral masses 36 yr after the initial detection of multiple liver metastases during a gastrectomy. The operation had been performed to remove four ulcerated polypoid gastric lesions. Reexamination of the previous liver and gastric biopsy specimens revealed a gastric leiomyoblastoma with metastases to the liver. The smooth muscle origin of this tumor was confirmed by positive staining for desmin intermediate filaments. This very long survival is extremely unusual in cases of metastatic gastric leiomyoblastoma.
