Background: Increasing evidence suggests pernio-like lesions are cutaneous manifestations of coronavirus infectious disease 2019 (COVID-19).
Objective: To describe clinical and pathologic findings of pernio-like lesions in patients with confirmed or suspected COVID-19.
Methods: An international dermatology registry was circulated to health care providers worldwide through the American Academy of Dermatology, International League of Dermatologic Societies, and other organizations.
Results: We documented 505 patients with dermatologic manifestations associated with COVID-19, including 318 (63%) with pernio-like lesions. Patients with pernio-like lesions were generally young and healthy, with relatively mild COVID-19. Of 318 patients with confirmed or suspected COVID-19 by providers, 23 (7%) were laboratory-confirmed COVID-19 positive, and 20 others (6%) were close contacts of patients with confirmed COVID-19. Given current testing criteria, many patients lacked COVID-19 testing access. For 55% of patients, pernio-like lesions were their only symptom. In patients with other COVID-19 symptoms, pernio-like lesions typically appeared after other symptoms. Pernio-like lesions lasted a median of 14 days (interquartile range, 10-21 days).
Limitations: A case series cannot estimate population-level incidence or prevalence. In addition, there may be confirmation bias in reporting. We cannot exclude an epiphenomenon.
Conclusions: Pernio-like skin changes of the feet and hands, without another explanation, may suggest COVID-19 infection and should prompt confirmatory testing.

Article Synopsis
- This systematic review aimed to analyze the prevalence and characteristics of skin manifestations associated with COVID-19, as these can assist in diagnosis, especially since the details were unclear.
- The review included 31 studies with over 10,000 patients and found that the overall prevalence of skin manifestations was about 29%, predominantly observed in Africa, with hands, feet, and trunk being most affected.
- Patients with milder COVID-19 symptoms showed more specific skin conditions compared to those with severe cases, indicating that skin assessments should be a key part of evaluating and diagnosing COVID-19, particularly in adults and the elderly.

The novel coronavirus of 2019 (COVID-19) can affect multiple organ systems with a wide spectrum of illness severity. Its effect on the respiratory tract is well-documented and has resulted in considerable excess mortality worldwide. However, observed cutaneous manifestations of COVID-19 are rising, ranging from short-lived viral exanthems to vesicular eruptions and urticaria.

The currently available coronavirus disease 2019 (COVID-19) vaccines in South Korea include mRNA (Moderna and Pfizer) and adenoviral vector (AstraZeneca and Janssen) vaccines. Dermatologic side effects of COVID-19 vaccines range from local injection site reactions to systemic eruptions, including morbilliform rashes or erythema multiforme. Pernio-like lesions, one of the most common cutaneous manifestations of COVID-19, have been rarely reported post-vaccination.

Article Synopsis
- Cutaneous manifestations of COVID-19 in African populations are under-researched and might help in early diagnosis and prognosis of the disease.
- A literature review from December 2019 to March 2023 highlighted various skin lesions like multisystem inflammatory syndrome (MIS), showing differences based on severity and country.
- The study found that certain health conditions (like obesity and diabetes) are associated with these skin manifestations, which can emerge early, potentially aiding in the identification of COVID-19 cases.

Background: Despite the large number of articles published on skin lesions related to COVID-19, clinicopathological correlation has not been performed consistently and immunohistochemistry to demonstrate spike 3 protein expression has not been validated through RT-PCR.
Material And Methods: We compiled 69 cases of patients with confirmed COVID-19, where skin lesions were clinically and histopathologically studied. Immunohistochemistry (IHC) and RT-PCR was performed in skin biopsies.
