Inflammatory Myofibroblastic Tumor of the Right Kidney Mimicking a Locally Advanced Renal Carcinoma: A Case Report.

An inflammatory myofibroblastic tumor (IMT) is a rare neoplasm with an unclear origin that can arise anywhere on the body. It contains spindle cells (myofibroblasts) with different inflammatory elements. Primary IMT of the kidney is a clinically rare disease and is difficult to differentiate from other renal malignancies.

Intrapelvic malignant nerve sheath tumors presenting as acute urinary retention: A case report and literature review.

Malignant nerve sheath tumors (MPNSTs) are rare sarcomas tumors which rarely present as intrapelvic mass and are hard to diagnose clinically. We present a 29-year-old male patient presented with acute urinary retention and was diagnosed with large intrapelvic mass. After complete surgical resection, the histopathology confirmed the diagnosis of low MPNST.

Electron microscopy study of 496 cases of lupus nephritis: A single-center experience.

Introduction: Renal involvement is seen in about 40-82% of systemic lupus erythematosus (SLE) Asian patients. The exact diagnosis and classification of lupus nephritis are important for treatment and prognosis. This study aimed to investigate the value of electron microscopy (EM) in the diagnosis and classification of lupus nephritis compared with light microscopy.

Review of Renal Biopsies, A Single Center Experience.

No large study has been conducted on biopsy-proven nephropathies. Our aim was to report clinical and pathological pattern of kidney disease diagnosed by kidney biopsy in our center. This is a retrospective study on kidney biopsy during 7 years; we analyzed the results of kidney biopsies and their clinical data.

Acute interstitial nephritis in the south of Iran; an observational study.

Background: Acute interstitial nephritis (AIN) is an emerging cause of acute kidney injury (AKI) during the recent years.

Objectives: There is no data about prevalence, causes, clinical manifestation and outcomes of AIN in our region. Hence, in this study we aimed to find the prevalence of AIN and describe the causes, clinical presentation, and the outcome of AIN in the native kidney biopsies.

Histopathological features of intra-ductal carcinoma of prostatic and high grade prostatic intraepithelialneoplasia and correlation with PTEN and P63.

Background: The main morphologic differential diagnosis of intra-ductal carcinoma of prostate (IDC-P) is high grade prostatic intraepithelialneoplasia (HGPIN). Since IDC-P, unlike PIN, was strongly correlated with aggressive prostate cancer, differentiation of these is too necessary. So we evaluated immunohistopathological patterns and the prognostic factors of IDC-P and HGPIN, in radical prostatectomy samples.

NPHS2 gene in steroid-resistant nephrotic syndrome: prevalence, clinical course, and mutational spectrum in South-West Iranian children.

Introduction: Mutations in podocin (NPHS2) gene have the key role in the pathogenesis of steroid-resistant nephrotic syndrome (SRNS) in children, but data is scarce regarding their prevalence and natural course among different all ethnic groups. This study was aimed to demonstrate the spectrum of NPHS2 mutations in children with SRNS and to compare the clinical course of disease in patients with and without mutation.

Materials And Methods: All 8 exons of NPHS2 were sequenced in 99 children, including 49 with SRNS and 50 with steroid-sensitive nephrotic syndrome (control group) by DNA sequencing.

Pilot study of a new acrylic cage in a dog cervical spine fusion model.

Study Design: An experimental pilot study using an acrylic interbody cage in a dog cervical spine fusion model.

Objective: To compare bony fusion in autologous bone grafting with a novel acrylic cage in terms of preservation of disc height, biomechanical properties, and histologic characteristics.

Summary Of Background Data: Degenerative diseases of cervical intervertebral discs are commonly treated by anterior decompression and interbody fusion.
