Hand, Foot, and Mouth Disease in Adults.

Hand, foot, and mouth disease (HFMD) is a viral infection primarily affecting children, but it can occur in individuals of all ages. In this article, we present the atypical case of a 36-year-old male with no significant medical history who recurred to the emergency department with a three-day history of fever, sore throat, and a maculopapular rash. After an extended evaluation with normal blood tests, he was discharged home with a diagnosis of HFMD. This case underscores the importance of considering HFMD when evaluating adult patients with rashes, and patients should be reassured about the self-limiting nature of the disease.
