Background: Peritoneal loose bodies are rare lesions that are usually found as an incidental finding during abdominal surgery. Large loose bodies, measuring more than 5 cm, are rare and only a few cases are reported in the literature. Peritoneal loose bodies are usually infarcted appendices epiploicae, which become detached and appear as a peritoneal loose body in the abdominal cavity.Case Presentation: We report here the first case, in the local Ethiopian context, of a giant “egg-like” loose peritoneal body measuring 7 × 6 cm found in a 50-year-old man who presented with a cramping abdominal pain and features of abdominal obstruction. The current hypothesis as regards these bodies and the diagnostic challenges is discussed.Conclusion: Small peritoneal loose bodies are common but giant and symptomatic ones’, like the one discussed here, are very rare and a diagnostic challenge. And, in the context of intestinal obstruction, a high index of suspicion is needed in order to diagnose them.

Gastrointestinal tract malignant melanoma is an uncommon form of neoplasm that may be either primary or metastatic. Diagnosis is often delayed until the illness becomes an emergency due to complications, such as intestinal hemorrhage, obstruction and perforation. We report a case of 42 year-old Ethiopian male patient presented to the emergency department with sign and symptoms of intestinal obstruction. The patient underwent laparotomy, ileo-ileal intussusception reduced and small bowel mass resection done. The histopathologic examination confirmed malignant small bowel melanoma. The purpose of this case report is to discuss clinical presentation and pathologic features of this rare condition with a review of the current literature.
