Immune thrombocytopenia possibly triggered by multiple tick bites

Resumen

Immune thrombocytopenia (ITP) is an autoimmune hematological condition characterized by a markedly isolated decrease in platelets without any apparent associated clinical conditions, resulting in bleeding and bruising of the skin, mucous membranes, and major organs. It is often triggered by preceding illness or several immune stimulants such as immunizations, infections, allergic reactions, among others. While uncommon, arthropod bites can trigger acute ITP. Four cases have been reported due to bee stings and insect bites, as well as a case of ITP following honeybee-venom therapy. Here, we report a case of acute ITP possibly triggered by multiple tick bites.
