Abstract

Lipoma is a frequent benign tumor of the soft tissue, but intra-articular locations are rare. We report a case that occurred in a rheumatoid knee. A 50-year-old woman had been treated for 17 years for seronegative deforming rheumatoid arthritis. Disease course under corticotherapy (7.5 mg/day) proceeded by flares and remissions. She had reported arthritis of the left knee for the past two years; concern about infection led to aspiration of the knee joint, which found inflammatory aseptic fluid, and radiography of the knee was normal. The patient was unable to afford magnetic resonance imaging or computed tomography. Synovial biopsy showed nonspecific chronic synovitis. Repeated corticosteroid injections produced no improvement. A second synovial biopsy was performed without specific results. Surgical biopsy followed and identified an intra-articular fatty mass, which was then excised surgically. Histologic examination showed a true synovial lipoma. True intra-articular lipoma, found mostly in the knee, is extremely rare and usually occurs de novo. For our patient its appearance in an arthritic knee required that lipoma arborescens be ruled out. MRI can provide a positive and differential diagnosis, but nonetheless requires hist...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.
