BACKGROUND Primary retroperitoneal mucinous cystadenoma is a rare tumor only 48 cases have been reported in international literature. Patients affected by primary retroperitoneal mucinous cystadenoma/cystadenocarcinoma ranged in age from 17 to 86 years (median, 42.3 years) and the size of the cystis ranged from 5 to 35 cm (median, 16.1 cm). There is no unanimous opinion on the genesis of these ...

Retroperitonal teratomas are rare. We report on a case of a retroperitoneal secondary localisation of a gonadal teratoma in a patient who had developed primary testicular teratoma 12 years previously. The retroperitoneal mass was detected with an abdominal CT requested for the management of a non-specific abdominal pain. CT and MRI examinations showed cystic retroperitoneal masses combined with...

context to review and summarize the literature regarding the current status of postchemotherapy laparoscopic retroperitoneal lymph node dissection (pcl-rplnd) in patients with testicular germ cell tumor. evidence acquisition a comprehensive review of the english literature was performed using the pubmed database using the terms “laparoscopy” or “laparoscopic”, retroperitoneal lymph node dissect...

Primary retroperitoneal carcinoma is a rare but highly aggressive tumour often resulting in infiltration of abdominal organs and diaphragm. We describe a case of retroperitoneal carcinoma infiltrating the diaphragm, the lower lobe of the left lung and ribs IX and X, but sparing the abdominal organs. After thoracoabdominal access, our patient underwent resection of the retroperitoneal carcinoma,...

Neuroendocrine tumors are either epithelial or neural in origin. Neuroendocrine tumors of the retroperitoneum are mostly metastatic. Primary epithelial neuroendocrine tumors of the retroperitoneum are exceedingly rare. We describe a case of a retroperitoneal tumor that was discovered incidentally during exploratory laparotomy for small-bowel obstruction. Histopathologic and immunochemical analy...

BACKGROUND Primary serous-papillary peritoneal carcinoma is able to spread to the retroperitoneal lymph nodes, but there is no evidence of the pattern of lymphatic metastasis. Because of the fact that this tumor entity is indistinguishable histologically from primary serous-papillary ovarian carcinoma, its taxonomic position has thus far remained unclear. MATERIALS AND METHODS The Medline dat...

Primary retroperitoneal pseudocysts are rare entities. Though laparoscopic approach has been described in their treatment, open surgical excision is still the mainstay of treatment for these lesions. We present a case of giant retroperitoneal pseudocyst and its successful laparoscopic excision. The patient was a 27-year old female. Contrast enhanced CT scan of the abdomen and ultrasonography co...
