Dengue fever presenting with severe myositis-An unusual presentation.

Dengue fever is an arbovirus (dengue virus DEN) disease caused by bite of mosquitoes, affecting people worldwide but is frequently seen as pandemic in Latin America and Asian countries. Among children it has been the most frequent reason for hospitalization and mortality. Symptoms range from subclinical disease to severe flu-like illness including myalgias. Dengue commonly presents as myalgia but myositis and/or elevated serum creatine phosphokinase (CPK) is rarely witnessed in dengue fever. Therefore, we present a case of dengue fever presenting as myositis: muscle weakness with raised creatine phosphokinase (CPK).
