Primary kidney parenchyma squamous cell carcinoma is extremely rare, and this is the forth case to be reported. In the present study, a case of a 61-year old man is discussed. The man presented with recurrent lumbago, gross hematuria for nearly 2 months, and suspicious inflammatory kidney diseases on contrast-enhanced computed tomography (CT) and fludeoxyglucose-positron emission tomography (FDG-PET)/CT, but a tumor can not be excluded completely prior to surgery. Finally, radical nephrectomy was performed, and histological analysis determined that the diagnosis was kidney parenchyma squamous cell carcinoma with inflammation invasion. The present case highlights the potential confusion of preoperative diagnosis of renal tumor with inflammation, and introduces the potential role of FDG-PET in its diagnosis and survival evaluation in renal malignancies.

Sulfatides or 3-O-sulfogalactosylceramide are negatively charged sulfated glycosphingolipids abundant in the brain and kidneys and play crucial roles in nerve impulse conduction and urinary pH regulation. Sulfatides are present in the liver, specifically in the biliary tract. Sulfatides are self-lipid antigens presented by cholangiocytes to activate cluster of differentiation 1d (CD1d)-restricted type II natural killer T (NKT) cells.

Introduction: Pseudotumors are benign lesions which may mimic like a malignant tumor on conventional imaging. They are formed in kidneys which are scarred and deformed by chronic pyelonephritis, glomerulonephritis, trauma or infarction. There is a diagnostic dilemma in most of the cases as to differentiate RCC and pseudotumors.

Background: Focal segmental glomerulosclerosis (FSGS) and treatment-resistant minimal change disease (TR-MCD) are heterogeneous disorders with subgroups defined by distinct underlying mechanisms of glomerular and tubulointerstitial injury. A non-invasive urinary biomarker profile has been generated to identify patients with intra-kidney tumor necrosis factor (TNF)-activation and to predict response to anti-TNF treatment. We conducted this proof-of-concept, multi-center, open-label clinical trial to test the hypothesis that in patients with FSGS or TR-MCD and evidence of intra-renal TNF activation based on their biomarker profile, short-term treatment with adalimumab would reverse the elevated urinary excretion of MCP-1 and TIMP-1.

BACKGROUND Emphysematous urinary tract infections are rare and serious conditions that are often multifactorial in etiology and may be associated with the presence of renal stones. Diagnosis can be made by finding gas within the renal collecting system or parenchyma. However, the radiographic finding of gas within a renal stone is rare and little has been published to describe the significance of this finding, its promoting factors, and management.

A 38-year-old woman received a 68Ga-FAPI-04 PET/CT scan for the evaluation of systemic lupus erythematosus. Diffuse uptake in both kidney parenchyma indicated the presence of lupus nephritis. In addition, an incidental carotid body tumor with increased FAPI uptake was also observed.
