Coronavirus Disease 2019 (Covid-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is recognized as a worldwide public health crisis. It has rapidly spread from Wuhan City in China after an outbreak of flu-like illness. Respiratory symptoms remain the most common manifestation of Covid-19. However, dermatologic manifestations have been observed in patients with COVID-19 infection. Kulkharni, et al. published a case report of morbilliform rashes as a probable herald of Covid-19 being its initial and only manifestation of COVID-19.1 This is a case of a 45-year-old female who presented with worsening morbilliform rashes on both upper extremities and was initially diagnosed with allergic contact dermatitis. She had no respiratory symptoms and was eventually diagnosed with Covid-19 in a routine Reverse Transcription Polymerase Chain Reaction test (RT-PCR). She was subsequently admitted for treatment and recovered after 2 weeks of hospital stay.

As anti-tumor necrosis factor alpha (anti-TNFalpha) agents are progressively being used in various medical conditions, dermatological adverse events have been encountered more frequently. To understand such dermatological conditions that have been documented while undergoing anti-TNF therapy, we reviewed relevant literature, including case reports and case series. Reported dermatological conditions included infusion and injection site reaction, cutaneous infection, psoriasiform eruption, dermatitis, allergic rash, lupus-like lesion, vasculitis, lichenoid reaction, granulomatous reaction, hair loss, cutaneous infection, and cutaneous neoplasm. These events had varying strengths of causal association and severity therefore, drug discontinuation may or may not be required.

Summary Cutaneous manifestations of Coronavirus disease (COVID-19) are variable. We present a case of non-drug related symmetrical flexural and intertriginous exanthema in a patient with COVID-19 infection. A 58-year-old Chinese male who was diagnosed to have COVID-19 infection, developed maculopapular erythematous rashes at bilateral axillary and inguinal folds on the fourth day of illness. He was treated symptomatically with anti-histamine and topical corticosteroid. The skin condition improved and he was discharged well on tenth day of illness. Although symmetrical flexural intertriginous exanthema isclassically caused by drug reaction, this case demonstrated the possibility of the rash being directly associated with COVID-19 infection. More cohorts should be evaluated to fully describe the full spectrum of dermatological manifestation in COVID-19.

PURPOSE: The aim of this study was to compare the clinical and laboratory features of infants with roseola infantum due to human herpesvirus 6 (HHV6) infection and those with urinary tract infection (UTI). METHODS: We retrospectively reviewed the medical records of children who were hospitalized at Cheil General Hospital and Women's Health Care Center, College of Medicine, Dankook University, and diagnosed as having HHV6 infection or UTI. RESULTS: Among the infants admitted between September 2014 and May 2016, 92 (male, 45 and female, 47) were included in the study and divided into a HHV6 infection group (n=50) and a UTI group (n=42). The relative risk of UTI compared with that of HHV6 infection increased with pyuria (P<0.001), increased with leukocytosis (mean white blood cell [WBC] count, 15,048±5,756/mm³ vs 87,916±54,056/mm³; P<0.001), increased with C-reactive protein (CRP) level (4.89±4.85 mg/dL vs 1.04±1.76 mg/dL; P<0.001), and younger age (6.3±3.2 months vs 18.3±12.6 months; P<0.001). The relative risk of HHV6 infection compared with that of UTI increased with fever duration (4.3±1.7 days vs 2.8±1.7 days; P<0.001) and decreased with platelet (PLT) count (373±94×10³/mm³ vs 229±90×10³/mm³; P<0.001). No significant differences were found between the HHV6 groups according to the presence or absence of pyuria. CONCLUSION: Pyuria, age, fever duration, WBC count, CRP level, and PLT count were the differentiating factors of HHV6 infection from UTI. However, sterile pyuria can occur in children with HHV6 infection. In the presence of pyuria, CRP level and PLT count were the strong predictors of UTI compared with HHV6.

Eosinophilic pustular folliculitis (EPF) is characterized by recurrent crops of pruritic, erythematous plaques studded with follicular papules and pustules that often form annular configurations. The distribution is usually asymmetric. A 27-year-old Korean man had atypical clinical findings with a butterfly rash-like symmetric erythema on the face without any papules or pustules and brownish patches with follicular papules on the back, which was diagnosed as EPF by histopathologic findings.

Hand-foot-mouth disease (HFMD), one of the more distinctive rash syndromes, is most frequently caused by coxsackievirus A16, but can also be caused by enterovirus 71 (EV71) and other coxsackieviruses. Recently, there have been large outbreaks of simple, neurologically complicated and even fatal HFMD caused by EV71 in Western Pacific Area. However, in the Republic of Korea, despite its location in EV71 endemic Western Pacific Area, published reports on HFMD with EV71 are rare and there are no published reports on fatal cases. After the first fatal case of HFMD caused by EV71 announced in May 2009, much more cases of neurologically complicated HFMD have been announced. Even now, physician's increased awareness about the seriousness of HFMD, viral surveillance and early warning system of HFMD, and early detection and proper management of potentially life threatening HFMD caused by EV71 are required in the Republic of Korea, as in the neighboring countries.
