Common clinical features of COVID‐19 are increasingly known but cutaneous manifestations are rarely described among healthcare workers. A review of cutaneous manifestations of COVID‐19 especially among healthcare workers (HCW) is thus required. The aim of our current study was to provide a comprehensive review of cutaneous manifestations of COVID‐19 among HCW through six case reports and a literature review. We conducted a literature search for cases reports, original and review articles using PubMed and the Google search engines. We included the written English studies that mentioned cutaneous symptoms during COVID‐19 infection. In addition to the review, 6 cases were collected among the HCW working at the Charles Nicolle Hospital of Tunis from September 2020 to January 2021. In our review, we included 17 articles in addition to our six cases. The type of papers was case series and case reports in respectively 8 and 9 studies. Skin manifestations were reported in two studies including two HCW, in addition to our series of six HCW. Skin manifestations were chilblain‐like lesions (44.5%), a generalized macular or maculopapular exanthem (32.1%), a papulovesicular rash and chicken pox‐like vesicles (11.5%), painful acral red–purple papules (4.6%), urticaria (2.8%), purpuric or petechial lesions (2.3%), and livedo reticularis lesions (0.45%). Of the 218 cases, 203 cases have reported the location of lesions. The very great majority of lesions were found on the trunk, hands, and feet. Fifty‐one patients (23.4%) experienced lesions on the trunk. The time of onset of cutaneous lesions was variable. At the diagnosis or the onset of COVID‐19 symptoms, 8.3% (18/218) of patients presented with cutaneous lesions. After the onset of respiratory symptoms or COVID‐19 diagnosis, 36.7% (80/218) of patients presented with cutaneous lesions. Of the 197 cases with reported healing times, healing times were up to 24 days. COVID‐19 has been associated with different cutaneous manifestations, likely of varying pathophysiology and severity, some preceding COVID‐19 symptomatology and others occurring during active disease or later in the course. Thus, heightened awareness and timely recognition of cutaneous manifestations in COVID‐19 are important for occupational physicians treating HCW with COVID‐19.

COVID-19 infection initially reported in Wuhan, China, 1 has been spread all over the world. As of July 7, 2021, COVID-19 has been diagnosed in more than 184 million people worldwide. 2 Its rapid spread across geographical borders leading to a pandemic can be explained by several factors such as the high rate of infectivity and transmission from asymptomatic persons. 3 The World Health Organization (WHO) has declared the COVID-19 outbreak as a Public Health Emergency of International Concern. COVID-19 pandemic still represents a great challenge for healthcare workers (HCW) around the world. 4 Healthcare workers are first-line fighters against COVID-19. They may experience symptoms ranging from influenza-like illness to life-threatening respiratory distress. 5 Apart from pulmonary involvement, it is interesting to note that multiple extrapulmonary manifestations associated with COVID-19 infection have been reported including skin manifestations. Common clinical features of COVID-19 are increasingly known but cutaneous manifestations are rarely described among healthcare workers. A review of cutaneous manifestations of COVID-19 among healthcare workers (HCW) is thus required.

The aim of our current study was to provide a comprehensive review of cutaneous manifestations of COVID-19 among HCW through six case reports and a literature review.

We conducted a literature search for cases reports, original and review articles published from the beginning of the COVID-19 pandemic until January 2021, using PubMed and the Google search engines. In our study, we used these key search words "cutaneous," "skin," and "dermatology" in combination with "coronavirus," "COVID-19," and "SARS-CoV-2." A manual search of reference lists of some relevant articles was performed. We excluded the studies that did not mention skin lesions.

We extracted the socio-demographic and clinical data from the included studies. Socio-demographic data were mainly the number of cases, age, gender, and status for COVID-19. The clinical data were mainly the description of the cutaneous lesions, its location, onset and healing time, and associated signs. The occupation was extracted from these studies when mentioned. In addition to the review, 6 cases were collected among the HCW working at the Charles Nicolle Hospital of Tunis from September 2020 to January 2021.

A 45-year-old nurse with a history of spontaneous pneumothorax, with no previous medication, or previous adverse drug reactions, presented to the occupational medicine department with a fever, a productive cough, asthenia, and body ache with no suspicious contact of COVID-19. The COVID-19 infection was confirmed by a positive RT-PCR on November 5, 2020. Anosmia, headaches, and dizziness occurred between Day 2 and Day 13 of the infection. The patient was treated with antibiotics based on azithromycin and a third-generation cephalosporin, combined with vitamins and preventive heparin therapy. The clinical course was marked by the appearance at Day 10 of an erythematous and pruritic cutaneous rash on the trunk and limbs with buccal ulcers without fever or signs of hemorrhages of the mucous membranes ( Figure 1 ). Clinical improvement of the rash was noted after taking corticosteroid injections for 5 days. The nurse returned to work after 25 days of the infection with a dry sequelae cough. A 44-year-old physiotherapist with a history of high blood pressure, paracetamol-drugged hepatitis, and an operated thyroid nodule tested positive to COVID-19 on October 7, 2020, with symptoms of ageusia, anosmia, and fever. She was treated with vitamin therapy and antibiotics based on azithromycin. Diarrhea and dizziness appeared, respectively, at Day 2 and Day 6 of the clinical evolution. She returned to work on October 20th with only hyposmia. One month later, on November 25, the patient reconsulted for an erythematous and pruritic herpetiform rash on the limbs and the abdomen without fever or other associated signs or medication use ( Figure 2) . A progressive and spontaneous improvement of the cutaneous lesions appeared after one week.

A 57-year-old midwife with a history of hypertension was tested COVID-19 positive on September 25, 2020, a sample indicated for body aches, asthenia, and headaches with a suspicious contact. She was treated with vitamin therapy for 10 days, combined with azithromycin for 06 days. She received preventive heparin therapy for 4 days. On Day 13 of the infection, the patient reported cutaneous lesions.

These lesions were objectified at the return-to-work medical examination. There was non-necrotic purpura (1-2 cm) on the legs and lower back, with no mucous lesions or fever. There were recurrent attacks that spontaneously resolved after 5-7 days. The patient was referred for further explorations. Skin biopsy showed a "necrotizing neutrophilic leukocytoclastic vasculitis" (Figure 3 ). Blood tests were normal, and immunological tests were requested. The patient was not put under corticoid or immunosuppressive treatment. The clinical evolution was marked by remission of cutaneous manifestations observed about two months after the onset of the disease around December 5, 2020.

A 32-year-old neonatology technician with no notable history presented on October 6, 2020, with fever, cough, shortness of breath, and body aches. The nasopharyngeal swab confirmed COVID-19 infection on October 7th. The patient was put under azithromycin for 9 days combined with a third-generation cephalosporin and vitamin therapy. On October 16th, 10 days after, the patient reported the appearance of cutaneous lesions, which were confirmed at the return-to-work medical examination on October 20. There was a pruritic rash on the lower limbs and the elbows, which improved after five days of antihistaminic treatment ( Figure 4 ).

A 33-year-old doctor, with no notable antecedents, was tested positive for SARS-CoV-2 on December 9, 2020, by a nasopharyngeal swab indicated for suggestive symptomatology of fever with anosmia and contact with a positive case. The clinical evolution was favorable under medical treatment. On December 23rd, 15 days after the infection, the patient reported a spontaneous cutaneous lesion on the left forearm with no fever, which was objectified at the medical check-up on December 25th. It was a well-limited superficial ecchymotic plaque of 07 cm long on the anterior face of the lower third of the left forearm which has spontaneously regressed after one week ( Figure 5 ).

A 50-year-old medical secretary, with no notable antecedents, was tested positive for SARS-CoV-2 on January 18, 2021, by a nasopharyngeal swab indicated for suggestive symptomatology of fever, cough, and odynophagia with no suspicious contact with a positive case. The clinical evolution was favorable under medical treatment. On January 23rd, 8 days after the onset, the patient presented with spontaneous pruritic maculopustular eruption on the chin, neck, and upper chest with lower back pain without fever. Cutaneous lesions have spontaneously regressed after one week ( Figure 6 ). Table 1 summarizes the characteristics and cutaneous manifestations of COVID-19 in our six reported cases.

Seventeen articles were selected for this review. There are 8 case series, 6-13 and 9 case reports. 14-21 The mean age was 49.8 years (20; 84). The gender was not reported in 17.9% of cases. In the other cases that mentioned the gender, sex ratio was 1.15.

COVID-19 infection was confirmed in 90.8% of cases. Skin manifestations among HCW were reported in two studies including two physicians, 19, 21 in addition to our series of six HCW. Table 2 summarizes the characteristics and cutaneous manifestations of COVID-19 cases published in scientific literature.

Skin manifestations were chilblain-like lesions (44.5%), a generalized macular or maculopapular exanthem (32.1%), a papulovesicular rash and chicken pox-like vesicles (11.5%), painful acral red-purple papules (4.6%), urticaria (2.8%), purpuric or petechial lesions (2.3%), and livedo reticularis lesions (0.45%). Of the 218 cases, 203 cases have reported the location. The very great majority of lesions were found on the trunk, hands, and feet. Fiftyone patients (23.4%) experienced lesions on the trunk. The time of onset of cutaneous lesions in relation to the onset of symptoms was variable. At the diagnosis or the onset of COVID-19 symptoms, 8.3% (18/218) of patients presented with cutaneous lesions. After the onset of respiratory symptoms or COVID-19 diagnosis, 36.7% (80/218) of patients presented with cutaneous lesions. The timeline of the appearance of the skin lesions was not mentioned in 55% of cases. Healing times were up to 24 days in 197 cases.

The severity of cutaneous lesions was not correlated with COVID-19 severity in 99% of cases. Only two studies by Mahé 19 and Estébanez 21 reported on the possible association between skin lesion severity and COVID-19 in 2 patients. Overall, histological findings were not reported. In our series, we have histological findings that may be related to the COVID infection in one patient.

Skin manifestations of the COVID-19 are not frequent as compared to the common clinical features such as shortness of breath, cough, and grippal syndrome. 22 In our study, we summarized the characteristics of cutaneous manifestations of COVID-19 cases published in scientific literature in addition to our case series (Table 1) . We wished to characterize these manifestations, particularly among HCW for further diagnostic and prognostic value because cutaneous manifestations of COVID-19 have been increasingly reported worldwide. Skin manifestations were reported in 8 case reports and 9 case series. In this review, 44.5% (97/218) of patients presented with chilblain-like lesions. In a previous review by Tan et al, 23, 24 the most common COVID-19 skin manifestations in the USA and Europe were the chilblain-like lesions. There was only 1 case reported in Asia. Rash containing macules and papules was the second cutaneous manifestation of COVID-19. However, rashes containing macules and papules were not specific to COVID-19, and there were reports of misdiagnosed cases of COVID-19 in patients with rash containing macules and papules. 20 In the study by Recalcati et al, 7 20.4% (18/88) of COVID-19 patients had developed skin manifestations. These manifestations were erythematous rash (77.8%), urticaria (16.7%), and vesicle formation (5.6%). These findings are nearly similar to our results.

Skin manifestations may aid in timely diagnosis of the COVID-19 infection even in the asymptomatic cases with no respiratory or common symptoms. We found that at the onset of the infection, 8.3% (18/218) of patients presented with cutaneous lesions.

In order to prevent the misdiagnosis of the COVID-19 signs, doctors' awareness of the skin lesions related to COVID-19 infection must be raised. 22 Furthermore, skin lesions may have several outcomes on the professional quality of life of HCW. Having new manifestations of the COVID-19 infection can lead to frequent consultations seeking care and treatment so that frequent absenteeism. Also, HCW may wonder if they could be assisted with compensation of their skin lesions as sequellae of the COVID-19 occupational disease.

Visible skin lesions present on exposed body parts may induce fear, disgust, aversion, or even intolerance 23, 24 . Furthermore, some people with limited awareness of skin lesions after COVID-19 infection believe that the disease still contagious, which may eventually contribute to the social isolation of persons with skin lesions. HCW with skin lesions may be subject to segregation and stigmatization, especially if the lesions are visible on the face and exposed body areas. Polymorphous cutaneous manifestations could reflect diverse interactions with the skin such as direct viral action in infected cells, hypercoagulability, and immune system hyperactivity. 24 The mechanisms of COVID-19 cutaneous lesions are not yet well known. Some studies have linked the cutaneous symptoms to a primary infection of the skin itself. In other theories, skin disturbances are seen as a secondary consequence after the respiratory infection. Suchonwanit et al reported that the late-onset of lesions may be related mainly to thrombotic vasculopathy and vasculitis. 25 Moreover, Litaiem et al reported a case in Tunisia of a 39-year-old female patient diagnosed with COVID-19 infection, and 18 days after hydroxychloroquine (600 mg daily) initiation, she developed a cephalocaudal spread of erythematous and pustular plaques. The Acute Generalized Exanthematous pustulosis (AGEP) was diagnosed. Skin lesions were significantly improving after hydroxychloroquine withdrawal. They hypothesize that pustular eruptions occurring in COVID-19 patients are more likely to support drug-related origin. 26 Gianotti et al described the histopathology of skin COVID-19 lesions with a spectrum of findings that ranged from mild spongiosis of the epithelial layer to the important situation of vasculitis and extravasation of red blood cells. 6 The scientific understanding of cutaneous manifestations in patients with COVID-19 is still evolving.

We believe that this work is the first study describing cutaneous manifestations of COVID-19 among HCW. However, several limitations must be considered. Due to evolving literature and language-related exclusion criteria, this paper only examines 218 cases. The inclusion of our cases was limited because of the low declaration by the patients and the quarantine restrictions. Moreover, publication bias was encountered. Drug side effects not mentioned in most of the studies must be taken into account. Also, occupation was not mentioned in several cases.

Further studies are still required to understand the mechanism and the link between skin lesions and COVID-19. So that prospective studies based on clinical and histological confrontations are needed. 12 

In summary, COVID-19 has been associated with different cutaneous manifestations, likely of varying pathophysiology and severity, some preceding COVID-19 symptomatology and others occurring during active disease or later in the course. Given the evolving state of evidence, occupational physicians should be aware of the variety of skin manifestations related to COVID-19 among healthcare workers. Thus, heightened awareness and timely recognition of dermatologic findings in COVID-19 are important for occupational physicians treating HCW with COVID-19. Further studies are still required to understand the mechanism and the link between skin lesions and COVID-19. So that prospective studies based on clinical and histological confrontations are needed.
