Myeloid sarcoma (MS) is a solid tumor of immature myeloid cells occurring in an extra-medullary site. MS can occur in de novo, as initial manifestation or concurrently with acute chronic myeloid leukemia (3-8%) and less frequently with other types of myeloproliferative disorders or MDS. Majority of the cases of MS involve the skin, lymph nodes, bone, or gastrointestinal tract. MS can however occur at virtually any extra-medullary site. We present a case of myeloid sarcoma of the neck in a patient with history of essential thrombocythemia that later transformed into Acute myeloid leukemia (AML).
