Fatal Myocarditis in an Adolescent Girl with Evolving Connective Tissue Disease.

Connective tissue diseases are rarely suspected and diagnosed in childhood and adolescence. Rarity of occurrence and poor disease acceptance among parents make them extremely difficult to treat in the early stages. An adolescent girl presented with features of pneumonia, was worked up and diagnosed as an evolving connective tissue disease. Her clinical characteristics did not fit into any specific disease. She was started on steroids and immunoglobulin as she had fulminant myocarditis with rapid downhill clinical course. High index of suspicion and aggressive immunosuppression can be life saving in exceptional situations even though a specific diagnosis cannot be ascertained.
