The Authors report their experience in cases of severe lower intestinal bleeding. On the basis of personal data and previously reported results, endoscopy is shown to be the primary and sometimes essential method, especially in the case of colo-rectal bleeding, both in terms of its diagnostic precision and possible therapeutic uses. This technique was used to treat all emergency cases, obtaining a diagnostic resolution in 85.6% and hemostasis and/or the concomitant removal of the lesion in 52.3% of cases.

Introduction: Melanoma shows a particular predilection in involving small intestine both in a single site and in multiple localization and acute or chronic gastrointestinal bleedings are often the first sign of tumour.
Presentation Of Case: We report two cases of GI metastases of malignant melanoma, one presented with only a big mass that cause intestinal obstruction and the other with a tumour spread throughout the small intestine that produce enterorrhagia.
Discussion: Diagnosis and follow-up are very difficult: CT scan, PET-CT scan and capsule endoscopy should be complementary for the assessment of patients with GI symptoms and melanoma history.
