ABSTRACT
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. CONCLUSION: What is the role of surgery? Several studies suggest metastasectomy to achieve both R0 results and palliative resolutions of acute symptoms, such as obstruction, pain, and bleeding.
ABSTRACT
Peritoneal mesothelioma is a rare form of malignant mesothelioma, making up <30% of diagnosed mesothelioma cases. Because of a lack of specific symptoms (abdominal pain, abdominal swelling), normally it is diagnosed in advanced stages, sometimes in a surgical emergency (intestinal obstruction, severe ascites) and occasionally during image procedures or laparoscopy which can show a mass developing from peritoneal mesothelium surfaces, or an accumulation of small irregularities that may be tumors or plaques. The reported case refers to a particular localization of a peritoneal mesothelioma, the spleen, discovered only after a splenectomy, due to the clinical and radiological suspect of a rupture.
