Abstract:

Thrombocytopenia is a very common hematological disorder that can be seen in many diseases such as splenomegaly diseases, infectious diseases, microangiopathic hemolytic anemias (TTP, HUS) that may occur due to drugs and malignant diseases infiltrating the bone marrow. Thrombocytopenia causes bleeding diathesis and causes petechial and purpuric rashes on the skin and mucous membranes. The petechial eruptions seen in thrombocytopenia are generally widespread throughout the body and are not limited to a single area. In this case report, we wanted to present a 78-year-old patient with thrombocytopenia, who had a diffuse and intense petechial rash on the anterior chest wall secondary to thrombocytopenia but did not have petechiae in other parts of the body.
