We reported the experience of high-dose chemotherapy (HDC) combined with peripheral stem cell transplantation (PBSCT) in 29 years-old man with advanced retroperitoneal germ cell tumor accompanied with left supraclavicular lymph node metastases, who obtained complete remission after comprehensive treatment. The initial levels of serum AFP, hCG and beta-hCG were high at 30.2 ng/ml, 14,000 mIU/ml ...

These tumors frequently metastasize to retroperitoneal lymph nodes, but only 5% of these tumors seed the gastrointestinal (GI) tract [3, 4], with the duodenum being the least common site (1.4%) [4]. Local extension from the retroperitoneal lymph node into the GI tract is the common method of spre...

Retroperitoneal fibrosis in a 12-year-old boy is reported. This was associated with a fibrotic mass in the neck which resolved spontaneously. Right-sided ureteric obstruction responded to treatment with steroids.

Retroperitoneal fibrosis (RPF) located unilateral perirenal without aorta involvement is very rare. We report a case of unilateral perirenal fibrosis which was misdiagnosed as malignancy even after biopsy. RPF should be in mind in dealing with perirenal mass.

A miner, known to have had lung silicosis for 30 years, was investigated for abdominal pain. A retroperitoneal mass was found, in which histological examination showed an inflammatory reaction to silica.
