RESUMO
Metastasis of uveal melanoma of the digestive tract is rare. We report a case of a patient with metastatic uveal melanoma of the liver and digestive tract. A 68-year-old man was admitted with primary complaint of appetite loss and fatigue. Abdominal computed tomography revealed a 13-cm diameter tumor in the right lobe of the liver. We diagnosed him with metastatic uveal melanoma. We performed a liver tumor biopsy and diagnosed metastatic melanoma;we found distant metastases in the stomach, duodenum, and rectum on endoscopic biopsy. We administered systemic chemotherapy [DACa-Tam therapy (Dacarbazine, 220mg/m2×3 days;Nimustine, 60mg/m2×1 day;Carboplatin area under the curve (AUC) =4×1 day;Tamoxifen, 40mg/day×3 days)]. Prognosis is unfavorable in approximately half of the patients with liver metastases that occur through blood circulation. The patient died of liver failure two months after the diagnosis.
