“…According to our own investigation based on Medline and Igakuchuo Zasshi data research, liver metastasis has been described in only 13 patients, including ours, in Japan (Table 1). 2,[4][5][6][7][8][9][10][11][12][13][14] Summarizing the characteristics of the patients with liver metastasis, the average age was 50.1 years, and the sex distribution was 8 men and 5 women. The primary lesion was located in the upper or middle portion of the stomach in all of the patients except ours.…”

A 20-year-old woman was referred to our hospital for detailed investigation of a gastric submucosal tumor. A leiomyoma was preoperatively diagnosed and laparoscopic-assisted enucleation was performed. The resected tumor was 4 x 3 x 1.5 cm in size and postoperative histological examination identified it as a gastric leiomyoblastoma. Therefore, a secondary resection in the form of a distal gastrectomy was carried out. No tumor cells were found in the gastric specimen or in the lymph nodes; however, 5 months after the operation, an abdominal computed tomography scan revealed a recurrence in the liver, and she was readmitted for further examinations. The lesion was diagnosed as a single liver metastasis from the gastric leiomyoblastoma and successfully resected. The histopathological findings of the liver tumor resembled those of the primary gastric tumor. Her postoperative course was uneventful and she has been well, without any evidence of recurrence, to date. Only 12 other cases of leiomyoblastoma of the stomach with liver metastasis have been reported in Japan, all of which were associated with a very poor prognosis. Therefore, patients with this unusual disease entity should be carefully followed up after resection of the primary tumor.
