[An uncommon cause of iron deficiency anemia].

A 55-year-old patient was diagnosed having a malignant melanoma metastatic to the small bowel as cause of an iron deficiency anemia. Although up to 60% of patients with metastatic melanoma are found to have intestinal metastases at autopsy, clinically apparent gastrointestinal involvement is rare during lifetime and often delayed after resection of the primary tumor. Diagnostic procedures include radiological imaging and endoscopic modalities. Early diagnosis is desirable for prognostic reason both in curative and palliative settings.
