title: [Duodenal diverticulum--an unusual manifestation of recurrent retroperitoneal liposarcoma].
abstract: The treatment of choice in retroperitoneal liposarcoma is curative R0 resection. However, there are high rates of reoperation due to recurrence. Our present case report shows difficulties in detecting recurrence due to atypical configuration. Eventually a huge diverticulum of the duodenum combined with leiomyoma in its neck area was histopathologically identified as a recurrent liposarcoma.
