Extramedullary hematopoiesis (EMH) is hematopoiesis in organs outside the bone marrow and most frequently occurs in the liver, spleen, and lymph nodes. We report a case of perirenal EMH revealed by kidney biopsy in a patient with primary myelofibrosis. We observed only bilateral kidney enlargement with plain computed tomography (CT) and ultrasonography before obtaining a renal biopsy. We obtain...

Renal biopsy in children can be performed either by percutaneous, laparoscopic, or open surgical approaches. As reported in a recent large pediatric series (Hussain et al., 2010), the percutaneous approach is by far the most commonly utilized, with the open approach typically reserved for situations in which percutaneous biopsy may be relatively contraindicated or there is the need for a large ...

Fine-needle aspiration biopsy of the spleen was performed on 18 patients shown to have amyloid deposits in other organs and on 17 control patients being investigated for proteinuria. Of the 18 patients with amyloid disease smears of splenic aspirate were positive in all cases, renal biopsy was positive in 16 out of 16 cases, and rectal biopsy was positive in seven out of 11 cases. None of the s...

BACKGROUND AND AIM The contribution of renal biopsy is of major importance in many renal diseases in children. In our study we aimed to evaluate retrospectively the indications, safety, efficacy and the spectrum of histopathological findings of percutaneous ultrasound-guided renal (PRB) biopsy during a 7 year period as well as to analyze specific groups of renal patients. PATIENTS AND METHODS...

background and aim: steroid-resistant nephrotic syndrome (srns) accounts for 10%-20% of all cases of idiopathic nephrotic syndrome. these patients are at risk of developing end-stage renal disease. the aim of this study was to determine the demographic characteristics, renal biopsy findings, response to immunosuppressive treatment, and prognosis in pediatric patients with srns.materials and met...
