A 71-year-old woman who underwent extended total resection of the right parotid gland for right parotid gland cancer (adenoid cystic carcinoma) in 1994 was found to have a giant liver tumor, about 10 cm in diameter, by ultrasonography (US) in 1998. No local recurrence or distant metastasis had occurred for these 4 years. Abdominal computed tomograpy (CT) showed the liver tumor, through which the portal branch passed. Doppler US showed spoke-wheel-like blood flow, and we suspected the possibility of focal nodular hyperplasia (FNH). Biopsy yielded a diagnosis of liver metastasis of parotid gland cancer, and she underwent extended right lobectomy of the liver. In 2003 after an uneventful postoperative course, US showed intraperitoneal tumors and a small liver metastatic tumor. Laparotomy revealed severe peritoneal dissemination of parotid gland cancer, and these were unresectable. Considering the characteristic of parotid gland cancer that may metastasize to the distant sites long after resection, we need careful long-term follow-up for these patients.
