Introduction:

chickenpox is a common and highly contagious rash disease caused by the varicella-zoster virus. In general, its presentation is benign, but serious complications may occur. In this article we present an adolescent who developed thrombocytopenic purpura as a complication of chickenpox.

Clinical case:

previously healthy 12-year-old female patient. Before admission, she had fever for six days, varicelloid rash, and epistaxis. On physical examination, in addition to the characteristic varicella rash, petechiae and ecchymosis were observed. Thrombocytopenia of 2,000/mm3 was documented. Acyclovir, immunoglobulin, and systemic corticosteroids were administered, as well as platelet transfusions, remaining hospitalized for more than two weeks, until recovery was achieved.

Conclusion:

serious complications of chickenpox such as thrombocytopenic purpura can occur in previously healthy and non-immunosuppressed patients.
