A rare case of acute promyelcytic leukemia (APL) is reported in a 7-year-old boy. The patient displayed the typical features of APL including impaction of the marrow with promyelocytes, marked elevation of the serum vitamin B12 and transcobalamin I levels and a hemorrhagic diathesis. The bleeding diathesis in the case was due to thrombocytopenia, and there was no evidence for disseminated intravascular coagulation.
报告了一例7岁男孩患急性早幼粒细胞白血病（APL）的罕见病例。该患者表现出APL的典型特征，包括骨髓中早幼粒细胞浸润、血清维生素B12和转钴胺素I水平显著升高以及出血倾向。该病例的出血倾向是由于血小板减少，且没有证据表明存在弥散性血管内凝血。
