Abstract
Malignant melanomas have the potential to metastasize to any site in the body.
They commonly invade the gastrointestinal tract. The small bowel is most
commonly involved, followed by the stomach, large bowel, and esophagus. The
vast majority of gastrointestinal melanomas are metastatic from a cutaneous lesion.
An abdominal CT scan revealed multiple and variable sized low density lesions
throughout the whole liver. Endoscopy revealed multiple black pigmentations at
the distal esophagus, stomach, duodenum and rectum. The brain CT showed
multiple hemorrhagic metastases in the brain. This 72-year-old man had malignant
melanoma in his right thumb one year ago. It had metastasized to the liver, lung,
gastrointestinal tract and brain. Here we report this case of whole body metastatic
malignant melanoma and review the literature.
