De novo myeloid sarcoma in a 4-month-old infant: a case report and review of the literature.
Myeloid sarcoma is a rare tumor of immature myeloid cells in an extramedullary site. Myeloid sarcoma may present in a variety of locations; skin is one of the common sites. It may precede or occur concurrently with acute myeloid leukemia, chronic myeloid leukemia, other forms of myeloproliferative disorders/myelodysplastic syndrome or de novo. ⋯ Chromosomal abnormalities were found at chromosomes 7, 10 and 11. The skin lesions resolved following multiple chemotherapy courses, then recurred requiring additional treatment. De novo myeloid sarcoma involving skin without evidence of leukemia can occur in an infant and may present a diagnostic challenge.
