Rewired functional regulatory networks among miRNA isoforms (isomiRs) from let-7 and miR-10 gene families in cancer.

Comput Struct Biotechnol J 2020 13;18:1238-1248. Epub 2020 May 13.

Department of Bioinformatics, Smart Health Big Data Analysis and Location Services Engineering Lab of Jiangsu Province, School of Geographic and Biologic Information, Nanjing University of Posts and Telecommunications, Nanjing, China.

Classical microRNA (miRNA) has been so far believed as a single sequence, but it indeed contains multiple miRNA isoforms (isomiR) with various sequences and expression patterns. It is not clear whether these diverse isomiRs have potential relationships and whether they contribute to miRNA:mRNA interactions. Here, we aimed to reveal the potential evolutionary and functional relationships of multiple isomiRs based on let-7 and miR-10 gene families that are prone to clustering together on chromosomes.

FDG Uptake in Brown Adipose Tissue Activated by a β3-Adrenergic Receptor Agonist Prescribed for Overactive Bladder.

Clin Nucl Med 2020 Aug;45(8):628-631

Diagnostic Radiology, Shiga General Hospital, Moriyama, Japan.

Brown adipose tissue (BAT), which produces energy and is known to play a role as a hibernating gland, is sometimes visualized on F-FDG PET in children or in slender young adults in a cold environment. Because BAT is activated by catecholamines, FDG uptake in BAT is also observed in patients with pheochromocytoma or paraganglioma. We present the case of an elderly woman with remarkable FDG uptake in BAT. Read More

The Diagnostic Dilemma of GATA3 Immunohistochemistry in Pheochromocytoma and Paraganglioma.

Endocr Pathol 2020 Jun;31(2):95-100

Department of Endocrinology, Metabolism, and Hypertension, National Hospital Organization, Kyoto Medical Center, Kyoto, Japan.

Although GATA3 has been recognized as a useful marker for mammary and urothelial carcinomas, there is large variation in GATA3 expression detected in pheochromocytoma (PC) and paraganglioma (PGL), from 90% to less than 5%. For GATA3 to be a useful diagnostic marker for PCCs/PGLs, the reasons for such discrepancy must be elucidated. Thus, we compared different immunohistochemistry protocols. Read More

Differentiating Nonfunctional Paraganglioma of the Bladder from Urothelial Carcinoma of the Bladder: Pitfalls and Breakthroughs.

Biomed Res Int 2019 6;2019:1097149. Epub 2019 Nov 6.

Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China.

Background: Although both nonfunctional paraganglioma of the bladder (NPB) and urothelial carcinoma of the bladder (UCB) are subtypes of bladder tumors, they are entirely different entities with distinct tissue origins and anatomical locations. However, NPB is frequently misdiagnosed as UCB chiefly due to the similarities in their clinical characteristics and cystoscopic features. This study aimed to compare the differences in their clinical characteristics and cystoscopic features. Read More

Composite paragangliomas are rare with less than 20 cases documented in the abdomen, retroperitoneum, and urinary bladder. In this article, we report the first case of composite paraganglioma in the head and neck presenting as a soft tissue mass in the neck adjacent to the carotid artery in a 50-year-old woman. We discuss the clinicopathologic findings and genetic implications, and we review the literature of this rare entity. Read More

The Diagnosis and Clinical Significance of Paragangliomas in Unusual Locations.

J Clin Med 2018 Sep 13;7(9). Epub 2018 Sep 13.

Department of Pathology, University Health Network, Toronto, ON M5G 2C4, Canada.

Paragangliomas are neuroendocrine neoplasms, derived from paraganglia of the sympathetic and parasympathetic nervous systems. They are most commonly identified in the head and neck, being most frequent in the carotid body, followed by jugulotympanic paraganglia, vagal nerve and ganglion nodosum, as well as laryngeal paraganglia. Abdominal sites include the well-known urinary bladder tumors that originate in the Organ of Zuckerkandl. Read More

Germline mutations in children and adults with cancer.

Cold Spring Harb Mol Case Stud 2018 08 1;4(4). Epub 2018 Aug 1.

Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, New York 10021, USA.

Mutations in succinate dehydrogenase complex genes predispose to familial paraganglioma-pheochromocytoma syndrome (FPG) and gastrointestinal stromal tumors (GIST). Here we describe cancer patients undergoing agnostic germline testing at Memorial Sloan Kettering Cancer Center and found to harbor germline mutations. Using targeted sequencing covering the cancer census genes, we identified 10 patients with germline mutations. Read More

Treatment responses to antiangiogenetic therapy and chemotherapy in nonsecreting paraganglioma (PGL4) of urinary bladder with SDHB mutation: A case report.

Medicine (Baltimore) 2018 Jul;97(30):e10904

Endocrinology.

Introduction: Paraganglioma (PGL) is a rare neuroendocrine tumor. Currently, the malignancy is defined as the presence of metastatic spread at presentation or during follow-up. Several gene mutations are listed in the pathogenesis of PGL, among which succinate dehydrogenase (SDHX), particularly the SDHB isoform, is the main gene involved in malignancy. Read More

A rare case of a I-MIBG SPECT/CT positive, but Ga-DOTA-TOC PET/CT negative pheochromocytoma of the bladder.

Rev Esp Med Nucl Imagen Mol 2018 Sep - Oct;37(5):315-317. Epub 2018 Jul 2.

Department of Nuclear Medicine, Medical University Innsbruck, Innsbruck, Austria.

Pheochromocytoma (PHEO) is rare and belongs to the group of neuroendocrine tumours (NETs). These tumours can be found anywhere from the neck to the pelvis associated with sympathetic ganglia. Morphological imaging, for example CT, provides excellent anatomical detail and high sensitivity but lacks specificity as difficulties may occur when distinguishing between tumours derived from the sympathetic nervous system and other tumour entities.

Postmicturition syndrome: a neglected syndrome dangerous for the bladder and the heart.

J Am Soc Hypertens 2018 08 18;12(8):589-593. Epub 2018 Jun 18.

Cardiology Department, ASST Nord Milano, Ospedale E. Bassini, Cinisello Balsamo, Milano, Italy. Electronic address:

Postmicturition syndrome refers to symptoms caused by overdistension of the bladder or micturition. Bladder paraganglioma is a rare neuroendocrine neoplasm, which arises from the chromaffin tissue of the sympathetic nervous system embedded in the muscle layer of the bladder wall. Clinical presentation of catecholamine-secreting paragangliomas may mimic that of hyperfunctioning adrenal pheochromocytoma. Read More

68Ga-PSMA-HBED-CC-Avid Synchronous Urinary Bladder Paraganglioma in a Patient With Metastatic Prostate Carcinoma.

Clin Nucl Med 2018 Sep;43(9):e329-e330

Urology, Post Graduate Institute of Medical Education & Research, Chandigarh, India.

Ga-PSMA-HBED-CC PET/CT has proven to be a useful modality in patients with prostate carcinoma, especially in those with suspected recurrence and in detection of locoregional and distant metastases. However, with expanding use of this tracer, several recent reports of in vivo expression of PSMA in nonprostatic benign and malignant entities have been published. We report a patient with PSMA-avid synchronous urinary bladder paraganglioma and metastatic prostate carcinoma. Read More
