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. Since the emergence of the SARS-CoV-2 pandemic, various dermatological manifestations have been demonstrated both following the de novo infection and the associated vaccination. [1] [2] [3] [4] These cutaneous adverse events have been either a new-onset dermatologic disorder or exacerbation of the pre-existing one. 5, 6 The new-onset or flare-up of psoriasis, lichen planus, eczematous dermatitis, and many other dermatoses have been reported following COVID-19. [7] [8] [9] [10] [11] On the contrary, dermatologic complications have also been abundantly observed after being vaccinated against SARS-CoV-2. 12, 13 However, SARS-CoV-2-related morphea has been reported only in few articles. Moreover, to our knowledge, morphea has not yet been demonstrated after COVID-19 vaccination and our case seems to be the first one. Here, we present two cases of new-onset morphea arising after SARS-CoV-2 infection and vaccination. A 29-year-old woman presented to the dermatologic clinic with multiple sclerotic skin eruptions all over her body. She mentioned a history of SARS-CoV-2 infection 4 months earlier. A few days after being infected, she had developed maculopapular lesions beginning from the upper extremities progressing to the trunk and lower extremities. The eruptions gradually turned to sclerotic lesions ( Figure 1 ). She did not have any comorbidities, and her medication history was not significant except for a course of interferon beta-1a during her SARS-CoV-2 infection. Complete blood count, chemistry panel, liver, renal and thyroid function tests, and coagulation parameters were in normal range. Complement component C3 and C4, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and ferritin levels were within normal limits. Serologic tests for ACE, ANA, RF, Anti-dsDNA, AntiRo, Anti La, Anti Sm, Anti Jo1, AntiScl70, Anti RNP, Anticentromere, Anti-CCP, and FANA antibodies were negative. Moreover, assessment results for tumor markers, hepatitis B virus (HBV), and hepatitis C virus (HCV) were also negative. Abdominopelvic ultrasound did not reveal any abnormality. We took skin biopsy of the eruptions, which demonstrated the epidermis overlying by basket weave cornified layer with basilar pigmentation and also the dermis infiltrated by perivascular and slight interstitial lympho-histiocytes and scattered plasma cells, with sclerotic change and diminished adnexa, all suggestive for morphea. We treated the patient with topical corticosteroids, but no response was observed. Therefore, we recommended the patient to undergo phototherapy. At the current time, she has passed her second phototherapy session with no considerable response. Yet, we are expecting to observe improvement with more prolonged duration of therapy. A 70-year-old woman attended our dermatology clinic with diffuse skin eruptions of one-month duration. She complained of a progressive maculopapular rash beginning from the arms, and extending to all the body surface, with gradual stiffness of the lesions. She acknowledged that the condition started 2 days after getting the first dose of AstraZeneca SARS-CoV-2 vaccine. Physical examination revealed multiple sclerotic skin eruptions all over the body including intertriginous areas ( Figure 2 ). Deep skin biopsy revealed sclerodermoid changes. Her polymerase chain reaction (PCR) test for SARS-CoV-2 was reported negative. Other laboratory tests including complete rheumatology panel were normal. Tumor markers and other assessments for malignancies also did not reveal an underlying cancer. Our patient refused to undergo phototherapy, so we started her on methotrexate and topical corticosteroids and are waiting to see the response. The present report investigated two cases of generalized morphea that developed and rapidly progressed within a few days after SARS-CoV-2 infection and vaccination, both in individuals with no history of rheumatologic or autoimmune disorders. Localized scleroderma, also known as morphea, is a dermatologic disorder which leads to loss of elasticity and hardening of the skin. This dermatosis is classified as plaque morphea, generalized morphea, linear scleroderma, and deep morphea. 14 The generalized form of morphea is defined as skin induration and sclerosis in the form of plaques in at least four anatomic sites, including head-neck, each extremity, anterior trunk, and posterior trunk. 14 This condition is quite serious and rapidly progressive and has an unfavorable outcome. 15 Considering the characteristics and pattern of eruptions onset, our cases were considered as cases of generalized morphea. The pathophysiologic mechanism for morphea is still unknown; however, it seems to be the result of immune activation leading to connective tissue dysregulation. 16 Morphea might be related to some environmental factors such as trauma, radiation, medications, infections, and vaccines. 17 Borrelia burgdorferi has been the most common infective pathogen reported to be associated with morphea. 18 Other infections with probable association include hepatitis B virus (HBV), hepatitis C virus (HCV), cytomegalovirus (CMV), toxoplasma, helicobacter pylori, and human endogenous retroviruses (HERV). [19] [20] [21] [22] [23] [24] [25] Recently, we have confronted with cases of morphea following SARS-CoV-2 infection. 8, 9 The underlying mechanism might be the virus-induced inflammation, which gives rise to immune system activation or cross-reaction of the virus and the host skin antigens. 26 Skin is among the important organs that is involved in the course of any viral infection, including SARS-CoV-2, as we have demonstrated a wide variety of dermatologic complications in the settings of COVID-19, either as the presenting manifestation or occurring in the course of the infection. 1, 26 On the contrary, we can name diphtheria-tetanuspertussis (DTP), hepatitis B, BCG, and pneumococcal vaccines among the ones reported to be associated with morphea. [27] [28] [29] [30] [31] [32] However, most of the aforementioned conditions occurred locally and in the vaccine injection sites, rather than appearing in generalized types. 28, 30 Up to the present time, no case of morphea has been reported following SARS-CoV-2 vaccination. Nevertheless, it is expected to detect more cases due to the hyperimmune responses following any vaccines, including those for COVID-19. Due to the temporal relationship between the morphea onset and vaccine injection, and considering the negative laboratory results for infections, rheumatologic and malignant disorders, we attributed the condition of our second case to SARS-CoV-2 vaccination. It is important to note that morphea can also appear as a component of a systemic autoimmune disorder such as systemic scleroderma, lupus erythematosus, thyroiditis, eosinophilic fasciitis, and biliary cirrhosis. 33 Most cases of generalized morphea have been reported in association with positive serologic tests results for autoantibodies, particularly ANA. 34 We evaluated both of the patients for autoimmune rheumatologic diseases, autoimmune thyroiditis, HCV and HBV, and IgE levels, none of which turned positive. Moreover, some malignancies have been first presented with cutaneous manifestations, such as morphea. [35] [36] [37] Accordingly, we performed a thorough work-up to detect any malignancies being presented with morphea as a paraneoplastic sign. Therefore, we attributed the condition to infection and vaccination. Another important issue is the difficulty in differentiating between generalized morphea and systemic sclerosis clinically. However, the absence of Raynaud phenomenon and sclerodactyly and also the negative results for ANA, Anti-centromere, and AntiScl70 justified our diagnosis, which was confirmed with histopathology. 38 We should take into account that some of the therapeutics utilized for managing COVID-19 can lead to florid cutaneous reactions. 39 For example, Stevens-Johnson-like syndrome, acute generalized exanthematous pustulosis, and urticarial eruptions have been reported following hydroxychloroquine, acneiform eruptions, and localized scleroderma following ribavirin, and psoriasis, alopecia, cutaneous vasculitis, and lichenoid drug reactions have been observed after receiving interferons. 40, 41 Our first patient had received interferon beta-1a for her SARS-CoV-2 infection. There have been rare reports of localized morphea at the site of interferon injection 42 ; however, no case of generalized morphea has been reported in patients who had received this medication. Nonetheless, we should consider the medications, along with the de novo infection as the precipitating factors of the cutaneous reaction in our first patient. Topical tacrolimus, methotrexate, systemic steroids, D-penicillamine, mycophenolate mofetil, cyclosporine, imiquimod, and calcipotriol have all been applied in managing morphea 43 ; however, artificial ultraviolet (UV) radiation or phototherapy has been the most effective and the mainstay of treatment. 44 COVID-19, and recently the associated vaccines, have led to any dermatologic condition, including insignificant and critical ones. Therefore, we should take into account these entities in any patient presenting with new-onset or exacerbating cutaneous reaction.
