ABSTRACT
Malignant melanoma is a common malignancy that has potential to metastasize to any site. Metastatic disease involving the stomach and liver are difficult clinical problem and presenting symptoms include weight loss, fatigue, and nonspecific epigastric pain. Laboratory results, barium X-ray study, endoscopy, CT, arteriography, and MRI suggest a metastatic malignant melnoma of the stomach and liver. The diagnosis may be confirmed by endoscopic biopsy of the stomach and aspiration needle biopsy of the liver. Metastatic melanoma is generally incurable, with survival in patients with visceral metastases generally <1 year. A case is reported of a metastatic malignant melanoma of the stomach and liver in a 60-year-old male patient, that was discovered 11 years after an enucleation of a choroidal melanoma of the right eye.

A previously healthy 22-year-old woman was admitted with a complaint of right upper quadrant abdominal pain for 2 weeks. Her past history was not remarkable. On admission, HBsAg and anti-HCV were negative and alpha-FP was within normal range. Abdominal sonography and CT showed a mass in liver measuring 10 11 cm with features of central necrosis and hemorrhage. On 6th hospital day, hemoperitoneum developed suddenly. She underwent emergency laparotomy and trisegmentectomy. Intraoperative finding revealed a hemoperitoneum with a tumor filled with liquefied necrotic tissues. Microscopically, the tumor was mostly composed of pleomorphic spindle cells with abundant anastomosing vascular channels and partly composed of tumor cells with trabecular arrangement. On immunohistochemical staining, tumor cells reacted with cytokeratin and vimentin, while CD34 and hepatocyte staining revealed negative. She died 2 months after the operation. We report a case of rapidly deteriorated primary sarcomatoid hepatocellular carcinoma in a young female without any risk factor.
