Partial hepatectomy for primary hepatic melanoma: A report of two cases and review of the literature

Abstract

Malignant melanoma is an extremely aggressive cancer arising from melanocytes, associated with the development of metastases in up to 20% of patients. Although the liver is a frequent metastatic site of malignant melanoma, primary hepatic melanoma (PHM) is rare. The treatment of PHM is controversial, and the prognosis for affected patients remains poor. We present two PHM patients who underwent partial hepatectomy at our institution and review the clinical and pathological data from these cases. Our results suggest that it is difficult to make a preoperative diagnosis of PHM without pathological results. For patients with resectable PHM, surgical resection is a potentially curative treatment.
