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.
免疫性血小板减少症（ITP）是一种自身免疫性血液疾病，其特征是血小板显著单独减少，且无任何明显相关临床病症，可导致皮肤、黏膜及主要器官出血和瘀伤。它常由先前疾病或多种免疫刺激因素引发，如免疫接种、感染、过敏反应等。虽然罕见，但节肢动物叮咬可引发急性ITP。已有因蜜蜂蜇伤和昆虫叮咬导致ITP的4例报告，以及1例蜜蜂毒液治疗后发生ITP的病例。在此，我们报告1例可能由多次蜱虫叮咬引发的急性ITP病例。
