BACKGROUND Mature cystic teratoma is one of the most common tumors of the ovaries; however, primary retroperitoneal lesions are rare entities in adults. CASE SUMMARY We report a case of a 33 year-old woman noticing a mass in her epigastric and left upper abdominal region without any specific signs and symptoms. Radiological evaluation revealed a retroperitoneal mass with extension from the po...
A 48-year-old woman developed symptoms related to a tumour attached to the outflow tract of the right ventricle. Eleven years earlier she had undergone hysterectomy for leiomyosarcoma, and 4 years later a retroperitoneal mass was removed. One year later a further retroperitoneal mass was removed, and after a further 4 years a cutaneous tumour was removed from her back. Histologically these thre...
Benign multicystic peritoneal mesothelioma (BMPM) is an uncommon lesion. It presents as a lump in abdomen or a finding seen on imaging modalities. Surgery is the primary modality of treatment. However, it has a high recurrence rate; this results in adhesions and subsequent surgeries difficult. We present a case of recurrent BMPM in a female operated twice earlier in a rural centre. Imaging moda...
PURPOSE Retroperitoneal iliac procedures can enable successful endovascular repair of abdominal aortic aneurysm (AAA) in patients who otherwise would not be anatomically eligible. The purpose of this study was to determine perioperative outcome with adjunctive retroperitoneal procedures compared with standard bilateral femoral exposure. METHODS Between August 1997 and November 2002, 164 patie...
Primary retroperitoneal mucinous cystadenocarcinoma is a rare tumor. Only about 30 such cases have been reported in the worldwide literature, and a few Korean cases have been reported. The pathogenesis is not clear, and coelomic metaplasia of the retroperitoneal mesothelium has gained wide support. There is no consensus on the appropriate treatment, but surgical exploration is needed for the di...
Retroperitoneal tumors, whether primary or resulting from the metastasis of other tumors, are a real challenge for the surgeon, in terms of their diagnosis and treatment. They are relatively rare, under 0.2% of the total number of tumors. The clinical examination of retroperitoneal tumors is uncharacteristic and misleading, consisting mainly in palpation of the tumor proper and in assessment of...
Extraskeletal osteosarcoma is an uncommon high-grade malignant soft tissue sarcoma. Well-differentiated extraskeletal osteosarcoma is thought to have a better prognosis than classical extraskeletal osteosarcoma, but dedifferentiation after recurrence has also been reported. We present a case of a primary retroperitoneal extraskeletal osteosarcoma in a 62-year-old Japanese woman. Abdominal CT re...
Primary retroperitoneal cysts are rare benign lesions which often present as an incidental radiological finding and also cause abdominal symptoms. A 47-year-old woman was admitted to the surgery unit because of right-sided abdominal pain. Computed tomographic scan investigation confirmed a circumscribed, oval, dishomogeneous mass in the right anterior pararenal space. The final diagnosis was ob...
Hemoperitoneum due to a ruptured retroperitoneal varix is an exceedingly rare condition and a poor prognostic sign with catastrophic and life-threatening complication of portal hypertension. We present a unique case of a 56-year-old female with cirrhosis secondary to primary sclerosing cholangitis who presented with acute abdominal pain and hypovolemic shock prior to a cardiac arrest following ...
Between 2 and 5% of malignant germ cell tumors in males arise at extragonadal sites. The origin of extragonadal retroperitoneal germ cell tumors remains controversial. Whether these develop primarily in the retroperitoneum or are metastases of a primary testicular tumor has long been debated. We report a 38-year-old male who presented with abdominal pain and was diagnosed with retroperitoneal s...
