Congenital leukemia is a rare condition diagnosed at birth to 6 weeks of life with an estimated incidence of 4.7 per million live births. In a review, about 25∼30% of cases were well documented as leukemia cutis. We report a case of a 3-month-old infant presented with asymptomatic multiple erythematous to bluish patches and nodules, which had developed about two months ago. Biopsy of the cutaneous lesions revealed immature cells which are overall monotonous with large kidney shaped nucleus, prominent nucleoli and moderate cytoplasm. These atypical cells stained positive for leukocyte common antigen, lysozyme and CD68. With this result, a congenital leukemia cutis was diagnosed. Six months later, she underwent cord blood stem cell transplantation. Seven months after the cord blood stem cell transplantation, the bone marrow examination revealed a normal result. Leukemia can be presented in the skin, the eruption may be nonspecific and it may precede systemic involvement. The recognition is important because early diagnosis can lead to appropriate treatment, followed by better prognosis.
