| Abstract: | Primary retroperitoneal mucinous cystic tumors are extremely rare.These tumors can be classified as a primary retroperitoneal mucinous cystadenoma with or without borderline malignancy or primary retroperitoneal mucinous cystadenocarcinoma.The most common of these is primary retroperitoneal mucinous cystadenoma,which almost always occurs in female patients;only ten cases have been reported in males.The most common clinical findings for this tumor type include nonspecific abdominal pain and a palpable abdominal mass.A definitive diagnosis is usually obtained from histopathology after surgical excision.Here,we report the case of a 60-year-old female patient who complained of abdominal pain that had been present for 3 mo and presented with a palpable abdominal mass.Multidetector computed tomography scanning revealed a large,unilocular cystic mass in the left retroperitoneal space.Surgical intervention was performed and the tumor was completely removed.Histopathologic examination confirmed that the tumor was a primary retroperitoneal mucinous cystadenoma.Two years after surgery,the patient remains disease free. |
