Schwannomas are benign tumors mostly arising from the head and neck. Retroperitoneal schwannomas are rare. Here we report the case of a 68-year-old woman with multiple retroperitoneal schwannomas. An abdominal computed tomography (CT) scan showed 1 non-enhancing mass with a low-density area, 4.6 cm in diameter, in the left adrenal region and another non-enhancing mass with a low-density area, 2...

BACKGROUND Malignant triton tumors are relatively rare and highly aggressive tumors in which malignant schwannoma cells coexist with rhabdomyoblasts. Their occurrence in the retroperitoneum is uncommon and has been rarely reported. CASE PRESENTATION We present the case of a patient with a retroperitoneal malignant triton tumor. A 32-year-old male was referred with epigastric pain and an abdom...

introduction hemangiopericytomas (hpcs) are rare neoplasms which account for approximately 1% of primary vascular tumors. case presentation we report a 73 years old woman with vague abdominal pain who did not have further significant symptoms and was diagnosed to have retroperitoneal hemangiopericytoma. discussion the tumor was initially diagnosed by ultrasound evaluation. mri showed a lobulate...

Malignancy is one of the most frequent cause of death in children -in U.S. it is the second common cause (second to Tranma). Between childhood malignancy leukemia is by far the mO'st frequent one and C.N.S. tumors take the second place -abdominal tumor re­main the third common cause of children's malignancy -Retroperitoneal space with organs like, kidney, adrenal gland, sympatheti nervous syste...

Background Retroperitoneal schwannomas are extremely rare, as they account for only 3% of retroperitoneal tumors. Clinical symptoms are nonspecific and of late onset, meaning that these tumors are diagnosed at an advanced stage. Surgical resection is required for histological diagnosis and to prevent possible malignant transformation. Celioscopy offers numerous benefits, reducing postoperative ...

A patient with multiple basal cell carcinoma syndrome, a symptom complex characteristized by nevoid basal cell carcinomas of the skin, jaw cysts, skeletal abnormalities, and hyporesponsiveness to parathormone is presented. In addition, the patient had a retroperitoneal lymphagiomyoma, a hamartomatous lesion, causing ureteral obstruction. The association of neuroectodermic syndromes and retroper...

The retroperitoneum is a closed space harbouring vital organs including the great vessels, kidneys and adrenal glands, ureters, and the ascending and descending colon. Surgical management of retroperitoneal pathologies may need multiorgan resection in order to achieve complete surgical resection while preservation of surrounding organs should be attempted, especially in case of benign tumors. W...

ganglioneuromas presented as a retroperitoneal tumor around the vital organs is a rare entity. a case with unusual presentation is reported. young woman of 44 years old presented without any complaint ,that known during incidental abdominopelvic ultrasonography. it was treated with partial resection for debulking surgery. debulking surgery with preservation of organ functions is feasible in the...

Abstract Background Retroperitoneal germ cell tumors (GCTs) are rare, commonly large tumors, often diagnosed in infancy. Complete surgical resection may pose a serious challenge as encasement of major vessels and organ displacement can lead to perioperative complications. This study aims illustrate the challenges excising retroperitoneal GCTs. Results Nine patients were included: six with terat...

BACKGROUND The incidence of testicular tumors in Poland accounts for 2.4 new cases per 100.000 men a year. When investigating the incidence with regard to age, we may notice three age ranges with the highest incidence rate: babyhood, 25-40 years of age, and age of about 60 years. A routine examination in patients with testicular cancer after the first course of chemotherapy is computed tomograp...
