Atypical Presentation of Scarlet Fever

Abstract

Scarlet fever is an infectious illness, which is caused by Streptococcus pyogenes. It causes exanthema and a characteristic tonsillopharyngitis. Its diagnosis is typically straightforward. However, due to the diverse clinical presentation of scarlet fever, one has to be cautious about atypical rash distribution that might go unrecognized or be misdiagnosed. Despite the fact that scarlet fever is primarily a pediatric illness, it can affect people of any age group. The case presented describes the clinical difficulty in the diagnosis of scarlet fever in an adult patient with atypical rash distribution involving dorsum of the hand and feet only till the level of wrists and ankles joints. A high degree of suspicion is required to diagnose this rare presentation and early treatment is essential to limit the spread of the disease.
