Successful Management of Erythema Dyschromicum Perstans Following Topical Ruxolitinib Therapy.

Erythema dyschromicum perstans (EDP) is a rare cutaneous disorder in which patients develop gray or blue-brown macules or patches on their bodies.1 This condition does not appear to have a gender or age predilection. The diagnosis of EDP is essentially clinical, with histopathology findings being nonspecific. To date, treatment for EDP varies. The use of several therapies, including dapsone, clofazimine, retinoid A, tacrolimus, and ultraviolet light have been reported but with minimal effectiveness.5 We report a case of EDP occurring in a patient following the COVID-19 vaccine that was given topical ruxolitinib with success in treatment. To our knowledge, this is the first report of the use of topical ruxolitinib in treatment of EDP with successful management. J Drugs Dermatol. 2022;22(3): doi:10.36849/JDD.7156.

A 25-Year-Old Patient With Chest Wall Erythema and Tenderness Who Was Ventilated Mechanically.

CASE PRESENTATION: A 25-year-old man with cerebral palsy, scoliosis, and ventilator dependence since SARS-CoV-2 infection 11 months earlier presented with a 2-week history of chest redness and swelling. The area of erythema and edema was located on the left side of the anterior chest and had grown to approximately 9 cm in diameter over the 2 weeks. It was tender to palpation. There was no history of trauma, injury, or bug bites at that site. He had not had a rash or similar lesions elsewhere on his body and had not taken any new medications. He did have increased, thick, yellow secretions from his tracheostomy, but no fevers. He was born in the Dominican Republic and moved to the United States as a child. He had not traveled anywhere outside the United States in more than a decade.

Top 10 acral skin manifestations associated with COVID-19: A scoping review.

COVID-19-associated cutaneous manifestations are one of the most important and relatively common extra-respiratory presentations of SARS-COV-2 infection. The exact identification and classification of these lesions can facilitate the accurate diagnosis and treatment. There are several case reports and small case series which describe cutaneous lesions in hands and feet. Currently, there is no scoping review about acral skin manifestations associated with COVID-19. This paper covers the COVID-related acral skin manifestations in 10 entities including acral papulo-vesicular eruption, acral urticarial lesion, acral non-inflammatory purpura and necrosis, acro-ischemia associated COVID-19, acral vasculitis, chilblain-like lesion (COVID Toe), acral erythema multiform (EM) like lesion, hand and foot skin lesions associated with multisystem inflammatory syndrome in children (MISC), acral peeling conditions and red half-moon nail sign. Future studies should focus on exact investigation of etiologies of these lesions including role of immune senescence, environment, gender, immunogenetics and relation of these lesion with major organ involvements.

SARS-CoV-2 and Skin: The Pathologist's Point of View.

The SARS-CoV-2 pandemic has dramatically changed our lives and habits. In just a few months, the most advanced and efficient health systems in the world have been overwhelmed by an infectious disease that has caused 3.26 million deaths and more than 156 million cases worldwide. Although the lung is the most frequently affected organ, the skin has also resulted in being a target body district, so much so as to suggest it may be a real "sentinel" of COVID-19 disease. Here we present 17 cases of skin manifestations studied and analyzed in recent months in our Department; immunohistochemical investigations were carried out on samples for the S1 spike-protein of SARS-CoV-2, as well as electron microscopy investigations showing evidence of virions within the constituent cells of the eccrine sweat glands and the endothelium of small blood vessels. Finally, we conduct a brief review of the COVID-related skin manifestations, confirmed by immunohistochemistry and/or electron microscopy, described in the literature.

Acral lesions in a pediatric population during the COVID-19 pandemic: a case series of 36 patients from a single hospital in Spain.

BACKGROUND: To describe the cutaneous acral findings in a pediatric population noticed during this pandemic. METHODS: A retrospective descriptive study was performed collecting data on 36 patients under 14 years old, presenting suspicious acral skin manifestations for coronavirus disease 2019 (COVID-19). RESULTS: Patients were mostly male (63.8%). The mean age was 11.11 years. 66.67% of patients showed erythematous papules, and 44.44% purpuric macules. Feet were affected in 97.22% of patients and hands in 5.55%. Lesions were asymptomatic in 50% of patients. 30.55% of patients showed extracutaneous findings, preceding skin lesions in 12.62 days. Seven patients underwent specific severe acute coronavirus 2 (SARS-CoV-2) testing; all of these patients tested negative. CONCLUSIONS: The association between these symptoms and SARS-CoV-2 remains unclear. We recommend using these manifestations as a sign of SARS-CoV-2 infection in children. This could lead to the examination of asymptomatic and mildly symptomatic children so that contagions may be avoided.
