Xanthogranulomatous pyelonephritis in adults: clinical, biological, radiological and therapeutic main findings in diffuse and focal forms. About 42 cases.

Introduction: Xanthogranulomatous pyelonephritis (XGPN) is a particular form of chronic renal suppuration characterized by the destruction of renal parenchyma and its replacement by a granulomatous tissue containing xanthomatous cells.

Objective: To report and describe the main clinical, biological, radiological and therapeutic aspects of xanthogranulomatous pyelonephritis in adults in focal and diffuse forms.

Methods: This was a monocentric retrospective study involving 42 cases of XGPN operated and histologically confirmed between 2005 and 2015.

Rare Case of a Well-Differentiated Paratesticular Sarcoma of the Spermatic Cord in a 60-Year-Old Patient.

. Liposarcomas are tumors that occur mostly in the retroperitoneum. Of all liposarcomas only 3 to 7% are found in the paratesticular region.

Comparison of circulating and intratumoral regulatory T cells in patients with renal cell carcinoma.

The clear evidence that tumor-infiltrating lymphocytes (TIL) exists in the tumor microenvironment raises the question why renal cell carcinoma (RCC) progresses. Numerous studies support the implication of CD4(+)CD25(high) regulatory T (Treg) cells in RCC development. We aimed in this study to characterize the phenotype and function of circulating and intratumoral Treg cells of RCC patient in order to evaluate their implication in the inhibition of the local antitumor immune response.
