Cystic Degeneration of Hepatocellular Carcinoma Mimicking Mucinous Cystic Neoplasm.

Korean J Gastroenterol 2019 May;73(5):303-307

Departments of Gastroenterology and Hepatology, Inje University Busan Paik Hospital, Inje University College of Medicine, Busan, Korea.

Spontaneous regression of tumors is an extremely rare event in hepatocellular carcinoma (HCC) with only a few reports available. With the accumulation of clinical information and tumor immunogenetics, several mechanisms for the cystic changes of HCC have been suggested, including arterial thrombosis, inflammation, and rapid tumor growth. This paper reports an uncommon case of the partial regression of HCC, which was initially misdiagnosed as a mucinous cystic neoplasm of the liver due to the unusual radiologic findings. Read More

Characterization of Australian Labradoodle dystrophinopathy.

Neuromuscul Disord 2018 11 29;28(11):927-937. Epub 2018 Aug 29.

Department of Pathobiology, Auburn University College of Veterinary Medicine, Auburn, AL 36849, USA; Scott-Ritchey Research Center, Auburn University College of Veterinary Medicine, Auburn, AL 36849, USA.

In humans, dystrophin mutations cause the X-linked recessive disorder known as Duchenne muscular dystrophy (DMD). These mutations result in skeletal and cardiac muscle damage with mortality increasingly associated with cardiomyopathy. We have identified a novel dystrophin mutation in exon 21 in a line of Australian Labradoodles; affected dogs develop progressive clinical signs including poor weight gain and weight loss, gait abnormalities, exercise intolerance, skeletal muscle atrophy, macroglossa, ptyalism, dysphagia, kyphosis, and a plantigrade stance.

Renal papillary necrosis in patients with sickle cell disease: How to recognize this 'forgotten' diagnosis.

J Pediatr Urol 2017 Jun 7;13(3):250-256. Epub 2017 Mar 7.

Department of Urology, University Hospital Antwerp, Edegem, Belgium.

Introduction: Renal papillary necrosis is not commonly seen in daily practice, but can have severe consequences when it is not diagnosed in time. It is known to be associated with sickle cell hemoglobinopathies; however a wide range of etiologies are possible, and it is therefore not the first diagnosis clinicians consider in patients with sickle cell disease who present with hematuria.

Methods: A literature search was performed to summarize the current knowledge about renal papillary necrosis associated with sickle cell disease. Read More

Nutcracker Syndrome and Sickle Cell Trait: A Perfect Storm for Hematuria.

J Gen Intern Med 2017 May 16;32(5):585-588. Epub 2017 Feb 16.

The University of Alabama at Birmingham, Birmingham, AL, USA.

We describe the case of a 27-year-old woman with a history of sickle cell trait (SCT) who presented with several months of hematuria and was found to have nutcracker syndrome (NCS). While SCT is a common cause of hematuria resulting from renal papillary necrosis, our patient had concomitant abdominal pain and anemia, prompting further evaluation and the subsequent diagnosis of NCS. Interestingly, the anoxia in the left renal vein from NCS predisposes patients with SCT to sickling. Read More

Department of Radiodiagnosis, St Johns Medical College, Koramangala, Bangalore, India.

Renal papillary necrosis is a clinicopathological entity where any or all of the papillae undergo selective necrosis, which can be demonstrated either radiologically or histologically. The most important causes are diabetes, pyelonephritis, obstructive uropathy, tuberculosis, analgesic abuse or overuse, sickle cell disease and renal vein thrombosis. Although this condition was first described in the 19th century the clinical diagnosis of this condition remains a problem to this day. Read More

The role of endoscopic ultrasound in the management of intraductal papillary mucinous neoplasms: a systematic update.

Minerva Med 2016 Dec 14;107(6):370-380. Epub 2016 Sep 14.

West of Scotland Pancreatic Unit, Glasgow Royal Infirmary, Glasgow, Scotland, UK -

The widespread use of cross-sectional imaging has led to an increased frequency of incidentally detected pancreatic cysts. Neoplastic cysts such as mucinous lesions and solid pseudo-papillary neoplasms have malignant potential and therefore the early detection of these lesions presents an opportunity for prevention or early detection and management of pancreatic adenocarcinoma. Serous neoplastic lesions and non-neoplastic pancreatic cysts such as pseudocysts or walled off pancreatic necrosis and are not associated with malignant potential. Read More

Section of Urology, Dartmouth Hitchcock Medical Center, Lebanon, New Hampshire.; Geisel School of Medicine at Dartmouth, Hanover, New Hampshire.

A 79-year-old woman with a history of diabetes mellitus and recurrent urinary tract infections (UTIs) presented with acute onset left lower quadrant pain, left-sided back pain, vomiting, and dysuria. Abdominopelvic CT scan revealed left hydroureteronephrosis to the level of the left ureterovesical junction (UVJ) where a bladder mass appeared to be obstructing the left ureteral orifice. The obstruction was ultimately found to be the result of a sloughed renal papilla lodged in the distal ureter, which created an inflammatory mass at the UVJ. Read More
