Department of Paediatric Nephrology, School of Medicine, Manisa Celal Bayar University, Manisa, Turkey.

Xanthogranulomatous pyelonephritis (XGP) is characterized by destruction of the renal parenchyma and granulomatous inflammation with lipid-laden foamy macrophages as well as inflammatory infiltration and intensive renal fibrosis. It generally occurs in adults, especially those in the fifth and sixth decades of life, but is occasionally seen in children as well. Brachydactyly mental retardation (BDMR) syndrome (OMIM 600430) is caused by a small deletion of chromosome 2q37 and is a rare condition, with roughly 100 cases reported worldwide. Read More

Imaging Manifestations of Acute and Chronic Renal Infection That Mimics Malignancy: How to Make the Diagnosis Using Computed Tomography and Magnetic Resonance Imaging.

Can Assoc Radiol J 2019 Nov 17;70(4):424-433. Epub 2019 Sep 17.

Department of Medical Imaging, The Ottawa Hospital, University of Ottawa, Ottawa, Ontario, Canada. Electronic address:

Purpose: To review the computed tomography and magnetic resonance imaging manifestations of acute and chronic renal infections that may mimic malignancy and to provide useful tips to establish an imaging diagnosis.

Conclusion: Acute and chronic bacterial pyelonephritis are usually readily diagnosed clinically and on imaging when the diagnosis is suspected based upon clinical presentation. When unsuspected, focal, extensive or mass-like, acute and chronic bacterial pyelonephritis may mimic infiltrative tumours such as urothelial cell carcinoma (UCC), lymphoma, and metastatic disease.

Surgical treatment of kidney tumor on a patient with second case of staghorn calculus and associated renal hydronephrosis: case report.

AME Case Rep 2019 11;3:19. Epub 2019 Jun 11.

Urology Department, Federal University of Amazonas (UFAM), Manaus, Amazonas, Brazil.

Staghorn, struvite or coral calculus are the ones that completely or partially occupies the renal pelvis and branches to the renal calices. The presence of renal calculi of any kind in the urinary tracts is related to the appearing of malign tumor in the kidneys, especially in the absence or failed treatment. A male patient, 51 years old, native of Manaus, reports about dysuria and polyuria associated with constant fever episodes and urinary tract infections with improvement by using several antibiotics but returning the symptoms after suspending it.

Ultrastructural evidence of the evolutional process in malakoplakia.

Histol Histopathol 2020 Feb 12;35(2):177-184. Epub 2019 Jul 12.

Department of Pathology, Yonsei University College of Medicine, Seoul, Korea.

Context: Malakoplakia can be caused by incomplete digestion of Escherichia coli by lysosomes, leading to recurrent urinary tract infections and consequential mass-forming events that mimic tumors.

Objectives: By using ultrastructural findings, we aimed to specify the process of phagolysosome to evoke malakoplakia.

Design: We observed a series of processes to form a peculiar Michaelis-Gutmann (MG) body in three patients with malakoplakia and compared with xanthogranulomatous pyelonephritis. Read More

While the development of a fistulous tract from the kidney to the proximal adjacent organs is relatively common, a tract leading to the skin is a rare occurrence. The primary cause of a fistula is prior surgical intervention or malignancy leading to abscess formation. Our case involves Xanthogranulomatous pyelonephritis (XGP) causing a longstanding lobulated abscess, ultimately leading to the formation of a fistulous tract. Read More

Eventually, the pathological diagnosis turned out to be XPGN. Most XPGN were unilateral, and there have been a few publications of bilateral involvement. Read More

Ancillary studies in fine needle aspiration of the kidney.

Cancer Cytopathol 2018 08;126 Suppl 8:711-723

Baptist Hospital of Miami and Miami Cancer Institute, Miami, Florida.

An increasing number of renal cell carcinomas (RCCs) require ancillary studies for diagnosis. The majority of renal fine needle aspirates do not require ancillary studies. Among the most common useful stains are cytokeratin 7 (separating clear cell RCC [negative] from papillary RCC, clear cell papillary RCC, and multilocular cystic RCC [positive] as well as separating chromophobe RCC [diffusely positive] from oncocytoma [focally positive/negative]) and CD117 (separating chromophobe RCC and oncocytoma [positive] from granular variants of clear cell RCC [negative]).

Department of diagnostic Ultrasound,d HospPeking University Thirital 100191, China.

Xanthogranulomatous pyelonephritis (XGP) is an unusual form of chronic pyelonephritis in which the renal parenchyma is destroyed and replaced by lipid-laden foamy macrophages. It usually affects middle-aged women with a history of recurrent urinary tract infection, diabetes, or kidney stones. The inflammatory process is usually diffuse and can extend beyond the kidney.

Urinothorax Caused by Xanthogranulomatous Pyelonephritis.

Case Rep Pulmonol 2018 14;2018:7976839. Epub 2018 Jun 14.

Department of Pulmonary Medicine, Joan C. Edwards School of Medicine, Marshall University, Huntington, West Virginia 25701, USA.

Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis that generally afflicts middle-aged women with a history of recurrent urinary tract infections. Its pathogenesis generally involves calculus obstructive uropathy and its histopathology is characterized by replacement of the renal parenchyma with lipid filled macrophages. This often manifests as an enlarged, nonfunctioning kidney that may be complicated by abscess or fistula. Read More

Pyeloduodenal Fistula in Xanthogranulomatous Pyelonephritis: A Series of Two Cases.

Perm J 2018 ;22:17-150

Surgeon in the Division of Transplant Surgery and the Division of Acute Care Surgery and Trauma at Memorial Regional Hospital in Hollywood, FL.

Xanthogranulomatous inflammation, characterized by destruction and replacement of tissues with chronic inflammatory cells, including foamy histiocytes and hemosiderin-laden macrophages, is uncommon. In patients with xanthogranulomatous pyelonephritis, inflammation may extend from the kidney to the overlying duodenum, creating a pyeloduodenal fistula that further complicates medical and surgical management. We present two cases with recurrent kidney infections who each ultimately received a nephrectomy and repair of their duodenal fistula. Read More

A Spectrum of Entities That May Mimic Abdominopelvic Abscesses Requiring Image-guided Drainage.

Radiographics 2018 Jul-Aug;38(4):1264-1281

From the Department of Radiology, Virginia Commonwealth University Medical Center, 1250 E Marshall St, PO Box 980615, Richmond, VA 23298.

A variety of entities may mimic drainable abscesses. This can lead to misdiagnosis of these entities, unnecessary percutaneous placement of a pigtail drainage catheter, other complications, and delay in appropriate treatment of the patient. Types of entities that may mimic drainable abscesses include neoplasms (lymphoma, gallbladder cancer, gastrointestinal stromal tumor, ovarian cancer, mesenteric fibromatosis, ruptured mature cystic teratoma, recurrent malignancy in a surgical bed), ischemia/infarction (liquefactive infarction of the spleen, infarcted splenule), diverticula (calyceal, Meckel, and giant colonic diverticula), and congenital variants (obstructed duplicated collecting system).
