title: Metastatic melanoma to the gastrointestinal tract: role of surgery as palliative treatment.
abstract: BACKGROUND
  Malignant melanoma is an uncommon metastatic tumor found in the gastrointestinal tract but most commonly involves the small bowel. Less than 5% of patients with metastases to the gastrointestinal tract are diagnosed antemortem. Clinical presentation could be an acute abdominal emergency such as a bowel obstruction, intussusception, bleeding and perforation or chronic symptoms with weight loss, abdominal pain and anemia.
  
  
  METHODS
  We report two unusual cases with acute gastrointestinal complications related to metastatic melanoma. Case 1 developed acute upper gastrointestinal bleeding and was diagnosed with gastric mass. Biopsy revealed metastatic melanoma. The patient died of his advanced disease. Case 2 with unknown primary melanoma presented with acute abdomen secondary to small bowel perforation. He underwent laparotomy and small bowel resection with palliative intent. The patient remains alive and free of symptoms at 4 year follow up.
  
  
  CONCLUSIONS
  Metastatic melanoma of the gastrointestinal tract should be suspected in any patient with history of cutaneous melanoma and new gastrointestinal symptoms. Surgical interventions for symptomatic patients with melanoma of the gastrointestinal tract significantly relieve pain and improve quality of life and may confer a survival advantage.
