[A case of retroperitoneal mucinous cystadenocarcinoma]

We reported is the histogenesis of a case of a primary retroperitoneal cystadenocarcinoma that was resected surgically in a 42-year-old woman who was admitted to hospital for SLE. On echographic examination, she was found to have a right abdominal tumor and underwent an operation for the complete removal of an abdominal tumor located in the right retroperitoneal cavity. A histological examination of the tumor revealed it to be compatible with a mucinous cystadenocarcinoma of the ovary. Only four cases of a primary retroperitoneal mucinous cystadenocarcinoma have been reported in the literature. This rare lesion was studied histopathologically and its histogenesis is discussed.
