Abstract

a) To provide a clinicopathological profile of Hürthle cell neoplasms (HCT) in our experience. b) To evaluate if there are any differences in the clinical or morphological features between three HCT categories: benign, malignant and indeterminate. c) To examine the role of the clinical and morphological features in predicting the behavior of these neoplasms. We reviewed the clinical reports of all patients with a histological diagnosis of HCT at our Hospital between 1981 and 1996. The final study group consisted of 25 cases. The neoplasms were divided into three categories on the basis of presence and degree of capsular and vascular invasion, marked nuclear atypia, tumour necrosis and pattern of growth. A series of clinical parameters were evaluated. Of the 25 tumors, 52% were morphologically classified as benign, 8% as indeterminate and 40% as malignant. Follow-up ranged from 10 months to 14.8 years or until death (average 3.8 years). There were four local recurrences (20%), three in the malignant group (30%) and one in the benign group (7.6%) (p = 0.15). One patient presented metastases and died because of tumor during the follow-up. Apart from capsular and vascular invasion and some aspects of therapy, no significant differe...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
