Haemorrhagic small bowel melanoma metastasis: a clinical rarity

We report on a clinical case with haemorrhagic small bowel metastases in a malignant melanoma patient with anaemia, diagnosed using small bowel video capsule endoscopy (VCE). A 67-year-old male patient with a previous diagnosis of malignant melanoma presented with anaemia and vertigo on admission. The standard diagnostic protocol for gastrointestinal (GI) bleeding investigation including a gastroscopy, colonoscopy and small bowel capsule endoscopy, as well as abdominal sonography and a restaging protocol including chest-abdomen-pelvis CT (CAP-CT), echocardiography and ECG was applied. Gastroscopy and colonoscopy were not conclusive in determining the bleeding source. VCE provided evidence for numerous haemorrhagic small bowel metastases. The CAP-CT was unremarkable for small bowel findings. Due to a diffuse metastatic disease diagnosed in heart, brain, liver, spleen and bone metastasis, the patient was treated in a conservative/palliative manner. VCE can provide precious information about GI bleeding of unknown origin when classical diagnostic methods are non-conclusive.
