Primary retroperitoneal mucinous tumors are rare neoplasms and almost exclusively seen in women. In this case report we present two cases of this entity with their clinicopathologic features. The first patient was a 32 years old unmarried woman presented with abdominal pain. Ultrasound imaging demonstrated a solid and thick walled ovarian mass m. 105* 70*80 mm. At laparotomy a large retroperitoneal mass with extention to pelvis, dome of urinary bladder and upper abdomen was found and omentum was involved by the tumor. Histopathological examination revealed a mucinous adenocarcinoma with mural nodule contained high-grade anaplastic carcinoma in retroperitoneal space. The second case was a 36 years old woman with retroperitoneal mucinous cystadenoma. The first case died of disease at first month of her diagnosis. Primary retroperitoneal mucinous tumors that containing anaplastic carcinoma or sarcomas are highly aggressive tumors with poor prognosis showing metastasis by high-grade component.
