Morphea induced by SARS-CoV-2 infection: A case report

Linear Morphea in the Context of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection: A Unique Dermatological Manifestation

Morphea, a rare skin disorder characterized by localized areas of thickened and sclerotic skin, typically presents as circumscribed plaques. The linear variant, however, manifests as linear bands of sclerosis affecting the extremities, and its association with coronavirus disease 2019 (COVID-19) has not been documented until now. In this article, we present the case of a 22-year-old previously healthy female patient who contracted COVID-19 complicated by an erythroedema on the back of the right hand, extending notably to the forearm on the 10th day of the infection. Skin biopsy revealed dermal and septal hypodermal fibrosis with a mild lymphocytic interstitial infiltrate in the dermis consistent with morphea. Treatment with low-dose corticosteroids was started, and regular follow-up was established. An isolated recurrence of cutaneous symptoms was observed after the first COVID-19 vaccination (Sputnik V) administered five months after the initial infection, with spontaneous regression in 10 days. This clinical evolution underscores the importance of a comprehensive understanding of dermatological manifestations in COVID-19, particularly in the context of post-infection vaccination.

Generalized morphea following COVID-19 vaccine: Case report and literature review

Physicians should be vigilant for COVID-19 vaccine side effects and investigate any associated cutaneous manifestations. This will ultimately facilitate better understanding and recognition of various skin reactions related to the vaccine.

Generalized morphea following the COVID vaccine: A series of two patients and a bibliographic review

The appearance of morphea after vaccination has been reported to date as single and deep lesions that appear exactly at the site of the skin puncture. It was therefore postulated that the origin could be the trauma related to the injection. The aim of this article is to review the various hypotheses offered in the published literature about generalized morphea following vaccination. We present two cases of generalized morphea after COVID-19 vaccination and review the published literature on immune-related cutaneous reactions. As previously reported, antigenic cross-reactivity between vaccine spike proteins and human tissues could cause certain immune-mediated diseases, including generalized morphea. Herein we report two cases of generalized morphea probably induced by the COVID-19 vaccine, given the temporal relationship with its administration. In summary, environmental factors such as vaccination against SARS-COV-2 could induce an immune system dysregulation, which would have an important role in the pathogenesis of morphea. We present two cases of generalized morphea probably induced by the COVID-19 vaccine, given the time elapsed between vaccination and the onset of the skin lesions.

Morphea in two patients after being infected to and being vaccinated against SARS‐CoV‐2 infection

Although the presence of morphea following COVID‐19 has been rarely reported, the development of its generalized form following COVID‐19 vaccination has not been reported yet. Here, we reported the first case of generalized morphea following COVID‐19 vaccination and another similar case following SARS‐Cov‐2 infection. Other etiologic factors were also dealt with.
