The most common form of isolated thrombocytopenia is idiopathic thrombocytopenic purpura (ITP) in childhood. Hence, pediatricians consider a possible diagnosis of ITP in patients with isolated thrombocytopenia who are admitted to hospital with complaints of skin findings such as petechiae, purpura, and ecchymosis. It is well known that cobalamin deficiency may also cause thrombocytopenia together with anemia and leukopenia in children. However, isolated thrombocytopenia due to cobalamin deficiency has rarely been reported in literature. In this case report, we present a 7-year-old female patient with isolated thrombocytopenia that was improved by cyanocobalamin therapy.
最常见的孤立性血小板减少症形式是儿童特发性血小板减少性紫癜（ITP）。因此，儿科医生会考虑对因皮肤瘀点、瘀斑和瘀斑等症状住院的孤立性血小板减少症患者进行 ITP 的可能诊断。众所周知，维生素 B12 缺乏症也可能导致儿童出现血小板减少症，同时伴有贫血和白细胞减少症。然而，文献中很少有报道维生素 B12 缺乏症引起的孤立性血小板减少症。在本病例报告中，我们介绍了一名 7 岁女性患者，其孤立性血小板减少症经氰钴胺治疗后得到改善。
