Methods: The medical records, clinical manifestations, signs, laboratory test results, diagnosis and treatment process of one patient admitted to our department on December 23, 2019 were reviewed, combined with the similar cases retrieved by “fulminant purpura” and “splenectomy” in the database, the clinical characteristics, treatment process and prognosis were analyzed and compared, and the possible diagnosis and treatment measures were discussed. Conclusion: Streptococcus pneumoniae causes acute infectious fulminant purpura (AIPF) and is good for developmental immune deficiencies, such as splenectomy or hyposplenism, and early recognition and treatment can improve the prognosis of patients.展开更多
