An atypical presentation of COVID-19: Hidden risk for seniors to misdiagnose.

The outbreak of coronavirus disease (COVID-19) was announced as a pandemic by the World Health Organization in March 2020. Clinical manifestations include cough, fever, dyspnea, myalgia, and loss of sense of smell and taste. Less common extrapulmonary signs and symptoms such as cutaneous manifestations, diarrhea, confusion, functional decline have been reported in the literature. Older patients with multiple comorbidities are at a greater risk for severe disease and death and are vulnerable to atypical presentations due to changes in organ systems, multimorbidity, cognitive impairment, and sensory disturbances. In this case, a 77-year-old patient diagnosed with COVID-19 pneumonia presented with atypically acute urticaria with angioedema was reported. Although there were no typical signs of the disease, such as cough or shortness of breath, the patient's laboratory values, and chest imaging were compatible with COVID-19. Therefore, the diagnosis of COVID-19 should be considered in older patients presenting with subtle signs or cutaneous manifestations.
