title: [Recurrent benign multicystic peritoneal mesothelioma: Approach to this rare condition].
abstract: BACKGROUND
  Benign multicystic mesothelioma is a rare benign tumour derived from the peritoneal mesothelium. The aim of this paper is to present a case of this rare tumour and review the clinical features, diagnosis and treatment of this disease.
  
  
  METHODS
  The case is presented of a 22-year-old female diagnosed with multicystic mesothelioma after an urgent resection of intra-abdominal tumour in the context of acute abdominal pain. In the subsequent follow-up, the patient had a recurrence of the lesion, and at 2 years was treated by further resection.
  
  
  CONCLUSIONS
  Benign multicystic mesothelioma is a benign tumour of unknown origin, and with a non-specific clinical manifestation. The most effective treatment is surgical, although there is a high tendency to local recurrence.
