The tumors that induce autoimmune hemolytic anemia (AIHA) are usually hematological neoplasms such as malignant lymphoma and chronic lymphocytic leukemia. AIHA associated with germ cell tumors is very rare with literature limited to case reports with most of them reported with ovarian dermoid, which abated with the removal of the tumor. We report an unusual presentation of AIHA with malignant sacrococcygeal germ cell tumor in a 3-year-old child, which rapidly disappeared after the excision of a sacrococcygeal teratoma.

作为副肿瘤综合征的自身免疫性溶血性贫血的骶尾部生殖细胞肿瘤的异常表现。

诱发自身免疫性溶血性贫血（AIHA）的肿瘤通常是恶性淋巴瘤和慢性淋巴细胞白血病等血液肿瘤。与生殖细胞肿瘤相关的 AIHA 非常罕见，文献仅限于病例报告，其中大多数报告与卵巢皮样有关，随着肿瘤的切除而减轻。我们报告了一个 3 岁儿童的 AIHA 与恶性骶尾部生殖细胞瘤的不寻常表现，在切除骶尾部畸胎瘤后迅速消失。
