Extramedullary (EM) manifestations of acute leukemia include a wide variety of clinically significant phenomena that often pose therapeutic dilemmas. Myeloid sarcoma (MS) and leukemia cutis (LC) represent 2 well-known EM manifestations with a range of clinical presentations. MS (also known as granulocytic sarcoma or chloroma) is a rare EM tumor of immature myeloid cells. LC specifically refers ...

BACKGROUND Leukemia Cutis (LC) consists in neoplastic leukocytic infiltration of the skin and is strongly associated with the presence of extramedullary disease and poor prognosis. However, there are few studies in the literature regarding this entity. We perform a retrospective study of 27 mexican patients in order to analyze the clinical features and prognosis of LC in Mexico, and a brief rev...
