Recognition and Management of Cutaneous Polyarteritis Nodosum Versus Livedoid Vasculitis: A Case Report

Curēus
Jessica ForbesMiguel Villacorta

Abstract

Cutaneous polyarteritis nodosum (CPAN) is a vasculitis of small and medium-sized muscular arteries of the dermis and subcutaneous tissue with no associated systemic involvement. A common presentation of CPAN can be misinterpreted as a non-invasive form of livedoid vasculitis, synonymous with the "atrophie blanche" which similarly presents as ivory-white stellate-shaped scars. Although hyperpigmentation can also be present, as seen in our 47-year-old female patient, cutaneous polyarteritis nodosum is unique due to the etiology of the inflammatory illness which requires a deep, segmented skin biopsy for diagnosis in order to identify the vessel inflammation. In this case report, we discuss a patient with a 20-year history of painful, recurrent ulcerations and polyneuritis with previous ulcer eruptions that healed as ivory-white stellate scarring. AB cutaneous forms of polyarteritis nodosum (PAN) may be only one manifestation of the disease, with other presentations in association with multi-organ system disease. This report will discuss the necessity of a high index of clinical suspicion with a clinical presentation similar to that of our patient. We will discuss the importance of early recognition and diagnosis of cutaneous vasc...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.
