Pseudoangiomatous stromal hyperplasia: a study of the mammographic and sonographic features

Abstract

To review the imaging features on mammogram and ultrasound of pseudoangiomatous stromal hyperplasia (PASH) of the breast. A systematic search of the breast cancer screening centre and pathology department database at a teaching hospital was performed to identify cases reported as PASH between 2000 and 2007. The findings on mammogram and ultrasound were reviewed. Information on demographics and clinical outcome were obtained from the patient's medical records. Seventy-three cases of PASH were identified, which occurred in women with a mean age of 51.1 +/- 10.5 years. The mean size of the lesion was 18 mm. Up to 70.8% of cases were radiologically detected and 29.2% presented as palpable masses. The most common appearance on mammography was of a solitary, non-calcified mass (30.4%) or localized increased stroma (30.4%). The distribution of mammographic findings differed in screen-detected patients compared with those presenting clinically (p = 0.015, Fisher's exact test). The most frequent sonographic appearance was of a well-defined hypoechoic mass (36.7%). Although there are emerging patterns associated with PASH on imaging, the features are not sufficiently specific to allow for a prospective diagnosis. Histological confirmatio...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.
