A case of recurred malignant melanoma of the stomach and peritoneum / 대한내과학회지

ABSTRACT

Malignant melanoma may spread through the lymphatic channels or via the bloodstream. The lung, liver, bone and brain are common sites of hematogenous metastases. Malignant melanoma that has recurred to the stomach or peritoneum is not common. An 83-year old male patient was admitted to the Department of Oncology due to abdominal distension; 13 years ago, the patient had previously received a complete surgical resection for malignant melanoma of the right heel. According to a computed tomography (CT) scan of the abdomen, peritoneal carcinomatosis was suggested. Under a gastrofiberoscopic examination, two small sized polyps with central umbilication were found on the midbody of the stomach. The gastric polyps were histopathologically confirmed as metastatic melanoma. We report a rare case of metastatic malignant melanoma that has recurred to the stomach and peritoneum 13years after its initial diagnosis.
