The symptoms of primary renal lymphoma (PRL) may mimic a renal cell carcinoma. Since the diagnosis is mostly after a radical nephrectomy, we recommend a percutaneous biopsy or cytology from the renal mass in patients who have features suggestive of a lymphoma. A magnetic resonance imaging may give an image more specific for a lymphoma. There are no clinical trials for the treatment of PRL, but all previously published case reports used R-CHOP and a few patients did better than the median survival of 6 months...

Epidermoid cyst of the renal pelvis is exceptionally rare. The histogenetic mechanism has not been well characterized. Herein, we report a case of intrarenal epidermoid cyst in a 62-year-old woman who had undergone left nephrolithotomy for a staghorn calculus. She was being followed up for bilateral renal cysts when a complex mass was noted arising from the lower pole of the left kidney. Renal ultrasound showed a small left kidney with a solid vascular echogenic mass. A laparoscopic radical nephrectomy was performed...

PURPOSE OF REVIEW: To explore the role of molecular imaging in the characterization of renal masses. RECENT FINDINGS: Incidentally detected renal masses exhibit variable malignant potential related to their underlying histology. Patients presenting with a renal mass should undergo individual risk stratification including characterization of their tumor histology. At the present time, anatomical imaging techniques are unable to reliably distinguish between the various renal tumor subtypes...

OBJECTIVES: To investigate whether morphologic analysis can differentiate benign versus malignant renal tumors on clinically acquired imaging. METHODS: Between 2009 and 2014, 3D tumor volumes were manually segmented from contrast-enhanced computerized tomography (CT) images from 150 patients with predominantly solid, non-macroscopic fat-containing renal tumors: 100 renal cell carcinomas (RCC) and 50 benign lesions (e.g. oncocytoma, lipid-poor angiomyolipoma). Tessellated 3D tumor models were created from segmented voxels using MATLAB code...

Limited therapeutic options exist for inoperable bilateral kidney tumors. We report the first ever use of proton therapy to treat primary renal cell carcinoma (RCC) and the first report of proton stereotactic body radiation therapy (SBRT) for RCC in an inoperable patient with synchronous RCCs treated with proton SBRT. The patient is a 47-year-old 450-pound female with multiple medical comorbidities, including Stage 3 chronic kidney disease (CKD), who was found to have bilateral renal masses during work-up for cellulitis and sepsis...

A 42-year-old man with eosinophilia and high serum immunoglobulin E (IgE) developed a lacrimal gland mass on the left side. Excisional biopsy revealed hyperplasia of lymphoid follicles, and infiltration with lymphocytes and eosinophils around lacrimal gland acini, leading to the pathological diagnosis of Kimura disease. IgE-positive cells were mainly found along follicular dendritic cells, and a small number of IgG4-positive cells was present. One month after oral prednisolone was started at 40 mg daily and tapered to 10 mg daily, he developed lower leg edema on both sides and marked proteinuria (10...

A 48-year-old woman was admitted to our hospital to undergo evaluation for fatigue, severe weight loss, and nephrotic range proteinuria. Light microscopy of a renal biopsy specimen revealed class III (A) lupus nephritis, while immunofluorescence and electron microscopy only showed sparse immune deposits with findings that were not typical of lupus nephritis. Computed tomography revealed a mass in the anterior mediastinum, which was resected. The examination of the surgical specimen revealed type A noninvasive thymoma...

OBJECTIVE: Interest in renal mass biopsies (RMBs) has increased in recent years. However, most publications are low-volume and/or single-center studies, so their generalizability is questionable. The aim of this study was to describe population-based, real-life use of diagnostic RMBs for localized and advanced kidney cancer (KC). MATERIALS AND METHODS: All KC patients diagnosed during 2008-2013 extracted from the database at the Cancer Registry of Norway were included...

RATIONALE: Both inflammatory myofibroblastic tumor (IMT) and retroperitoneal fibrosis are rare lesions, but kidney involvement is more rare. It is the first study about IMT of the kidney in a patient with perinephric and periureteric fibrosis and we hold that fibroblast proliferation may be an intermediate status in oncogenesis of IMT. But further investigation is necessary in order to better clarify the relationship between fibroblast proliferation and IMT. PATIENT CONCERNS: A 54-year-old female presented no positive signs except dull back pain after overwork...

REVIEW
Rosanna Dammacco
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology and with remarkably heterogeneous clinical features. Virtually any organ system can be affected, including the eye. SLE-related eye involvement can be diagnosed in approximately one-third of the patients and is usually indicative of disease activity. An early diagnosis and the adoption of suitable therapeutic measures are necessary to prevent sight-threatening consequences, especially in patients with juvenile SLE. Periocular lesions, such as eyelid involvement and orbital inflammation, are relatively rare and, in case of orbital masses, may require a biopsy control...

Amyloidosis is a heterogeneous group of disorders characterized by extracellular deposition of unique protein fibrils. The least common presentation of an amyloid deposition is as a discrete mass called amyloidoma or amyloid tumor. We report a case of a soft tissue amyloidoma in the abdomen of a 16-year-old girl who was diagnosed as having systemic amyloidosis. A girl aged 16 years was referred to our hospital with a pre-diagnosis of a retroperitoneal mass documented with abdominal ultrasonography and tomography...

We report a case of a persistent right upper lobe opacity following treatment for a Pseudomonas infection in an immunosuppressed patient with a recent renal transplantation. The patient underwent a surgical lung biopsy for definitive diagnosis of the mass. The lesion was composed of extensive calcifications deposited throughout the lung with associated fibrosis. The patient had a history of a remote parathyroidectomy for hyperparathyroidism; however, the parathyroid hormone (PTH) and the calcium levels were still mildly elevated...

INTRODUCTION: Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and more than 90% of neoplasms arising from the kidney. Uninformative percutaneous kidney biopsies vary from 10 to 23%. As a result, 7.5-33.6% of partial nephrectomies in patients with small renal masses (SRM) are performed on benign renal tumors. The aim of this study was to assess the feasibility of the apparent diffusion coefficient (ADC) of the diffusion-weighted imaging (DWI) of MRI, as RCC imaging biomarker for differentiation of SRM...

INTRODUCTION: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant disease. It is caused by constitutional mutations in the FLCN gene. Since BHDS is a rare syndrome therefore it is unknown to many physicians. However, it is important to identify this rare syndrome at early stages because incidence of renal cancer in BHD patients is very high and its detection at early stages can prevent its metastasis. Hence, we want to present a case of BHDS and draw the attention of the treating physician to this rare inherited disorder and discuss its appropriate diagnosis and management...

BACKGROUND: Focal renal masses are typically evaluated by means of triphasic contrast-enhanced CT or MRI scan but use of iodinated contrast or gadolinium is unsuitable for some patients. Contrast-enhanced ultrasound (CEUS) is an imaging alternative in this scenario but has limited availability in Ireland. AIM: The aim of the study was to retrospectively evaluate experience with selective use of CEUS for non-invasive characterization of focal renal masses in a tertiary referral institution in Ireland, with a particular focus on cystic renal lesions and the influence of CEUS on final Bosniak classification and treatment outcomes...

Chronic kidney disease (CKD) is a prevalent cause of morbidity and mortality worldwide. A hallmark of CKD progression is renal fibrosis characterized by excessive accumulation of extracellular matrix (ECM) proteins. In this study, we aimed to investigate the correlation of the urinary proteome classifier CKD273 and individual urinary peptides with the degree of fibrosis. In total, 42 kidney biopsies and urine samples were examined. The percentage of fibrosis per total tissue area was assessed in Masson trichrome stained kidney tissues...
