Urine Lactoferrin as a Potential Biomarker Reflecting the Degree of Malignancy in Urothelial Carcinoma of the Bladder.

Urothelial carcinoma of the bladder (UCB) is potentially life-threatening; therefore, we aimed to discover a novel urine biomarker for diagnosis and prognostication of UCB. This is a retrospective case-control study. Exploration of a new biomarker using urine from 20 UCB patients in the present study revealed that urinary level of lactoferrin (LF), a multifunctional glycoprotein released from neutrophils, was higher in 11 of 15 with invasive/high-grade UCB than 5 with non-invasive one, and 2 healthy adults.

Hereditary leiomyomatosis and renal cell cancer (HLRCC): A case report.

Hereditary leiomyomatosis and renal cell cancer is a rare, inherited disease caused by mutations in the fumarate hydratase gene. It is characterized by cutaneous leiomyomas, uterine leiomyomas, and/or renal cell cancer. We present the case of a 42-year-old woman with a heterozygous missense mutation (p.

Nuclear features of infiltrating urothelial carcinoma are distinguished from low-grade noninvasive papillary urothelial carcinoma by image analysis.

Recent advances in computer technology have been made and image analysis (IA) has been introduced into pathological fields. The present study aimed to investigate the utility of IA for the evaluation of nuclear features and staining of immunohistochemistry (IHC) for Ki-67, p53 and GATA-binding protein 3 (GATA-3) in urothelial carcinoma tissue samples. A total of 49 cases of urothelial carcinoma tissue samples were obtained by transurethral resection of bladder tumors, which included 11 low-grade papillary urothelial carcinomas (LGPUCs), 1 non-invasive high-grade urothelial carcinoma and 37 infiltrating urothelial carcinomas (IUCs).

Primary Villoglandular Mucinous Adenocarcinoma of the Vulva.

Primary villoglandular mucinous adenocarcinoma of the vulva is rare tumor. We report a case of 68-year-old woman who developed this very uncommon malignant tumor. Immunohistochemical examination of this tumor revealed positive staining for Cytokeratin 20, Mucin 2, and CDX2, although Cytokeratin 7 and Mucin 6 were negative.

Cholangitis as an initial manifestation of polyarteritis nodosa.

A previously healthy 89-year-old man was admitted to our hospital with right upper quadrant pain and mild fever. A diagnosis of cholangitis was suspected based on the patient's physical findings and imaging features. Although he received treatment typical for cholangitis, he suddenly died of shock for unknown reasons two months after disease onset.

Dolichoectatic vertebrobasilar dissecting aneurysm originating from atherosclerosis: an autopsy case.

We herein report an unusual case of profound brain infarction of the posterior circulation due to a dolichoectatic vertebrobasilar dissecting aneurysm (DVDA) originating from atherosclerosis. On autopsy, diffuse atherosclerosis was observed with a multi-fusiform aneurysm measuring 1 to 2 cm in diameter ranging from the left vertebral artery to the basilar artery. The microscopic findings of the aneurysm revealed severe stenosis of the artery caused by intimal thickening, intimal flap formation and thrombosis, indicating the presence of a dissecting aneurysm originating from atherosclerosis.
