Allograft dysfunction in a patient with an odd-looking kidney: case of renal lipomatosis and review of literature
نویسندگان
چکیده
Renal lipomatosis was diagnosed in a kidney transplant recipient who presented with acute kidney injury (AKI) several years after transplantation. The patient had an odd-looking kidney transplant on ultrasound and computed tomography (CT) scan, showing a medullary mass with resultant compression of the surrounding renal parenchyma. A biopsy of the renal medulla confirmed fatty infiltration of the renal parenchyma. The patient underwent percutaneous nephrostomy and AKI resolved with relief of the obstruction. Renal lipomatosis is a rare condition that should be differentiated from other neoplasms of the kidney. When it occurs in a functioning transplant kidney, the treatment approach proves to be very challenging.

Primary Leiomyosarcoma of the Kidney : A Case Report and Review of Literature
Primary sarcomas of the kidney are exceptional. Among renal sarcomas, leiomyosarcoma is the most common histologic subtype amounting to 50-60% of all cases. The tumor usually arises from either the renal capsule or smooth muscle tissue in the renal pelvic wall. In this paper, we report a patient with leiomyosarcoma of the kidney presented with non-specific abdominal pain and a palpable mass....

Background: The incidence of ischemic reperfusion injury (IRI) in early phase post-transplantation and activation of toll-like receptor (TLR-2) and TLR-4 remarkably impact the outcome of a renal allograft. Objective: To investigate whether the expression of TLRs in peripheral blood mononuclear cells (PBMCs) can predict the clinical outcome of kidney allografts. Methods: We obtained blood sample...
متن کاملRegulatory T Cell Subtypes and TGF-β1 Gene Expression in Chronic Allograft Dysfunction
Background: Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. Objectives: To eva...

Introduction:Detecting renal allograft dysfunction early will allow timely diagnosis and treatment. There is no objective recommendation by national kidney societies for glomerular filtration rate (eGFR) estimation in post-transplant setting. 99mTc-DTPA Technetium-99m Diethylene triamine penta acetic acid) renogram can identify early renal dysfunction much before ser...

Background: Calcineurin inhibitors (CNI) have significantly reduced the incidence of acute rejection. Nephrotoxicity however may contribute to long-term allograft dysfunction. Mycophenolate mofetil (MMF) may allow cyclosporine (CsA) dose reduction without increasing the risk of rejection. Methods: In seventy-eight living unrelated kidney transplant patients with renal dysfunction, we studi...
