Case ReportsMaxillo-ethmoidal chloroma in acute myeloid leukaemia: case report.
Chloroma, also called Granulocytic Sarcoma or Myeloid Sarcoma, is a rare malignant extra-medullary neoplasm of myeloid precursor cells. It is usually associated with myelo-proliferative disorders but its appearance may precede the onset of leukaemia. ⋯ Differential diagnosis is often difficult and includes acute lymphoblastic leukaemia, large cell NHL, lymphoblastic lymphoma and Ewing's sarcoma. The case is presented of a maxillo-ethmoidal chloroma occurring in a case of poor prognosis acute myeloid leukaemia, emphasizing the clinical and cyto-histological features and problems concerning differential diagnosis.
