title: Retroperitoneal myolipoma.
abstract: BACKGROUND
  Myolipoma is a benign tumour in which smooth muscle cells are mixed with adipocytes.
  
  
  METHODS
  A 34-year old lady presented with a mass in the right iliac fossa detected on computerised tomographic (CT) scan. Wide excision of the retroperitoneal mass was done. Histopathology showed features of myolipoma. There was no recurrence or metastasis at three years.
  
  
  CONCLUSIONS
  Myolipoma is a rare benign entity; hence a benign course and good prognosis are expected.
