  plasma cell myeloma
  Definition: Multiple myeloma (MM) is a malignancy of clonal bone marrow plasma cells characterized by a high genomic instability increasing with disease progression.
  MM is characterized by neoplastic proliferation of plasma cells involving more than 10% of the bone marrow.
  Multiple myeloma is a plasma cell malignancy characterized by complex heterogeneous cytogenetic abnormalities.

  erythroleukemia (EL)
  Historically, AML with erythroid features has been designated M6 by the French-American-British (FAB) group. The FAB criteria for M6 diagnosis are: bone marrow erythroblasts equal to or greater than 50% and blasts equal to or greater than 30% of the non-erythroid cells.
  The World Health Organization (WHO) have recently recommended that the requisite blast percentage for a diagnosis of AML be 20% or greater, and this includes erythroid leukaemia. AML M6 would equate to (...)

  Epidemiology
  Although insulinomas are very rare tumors, they are the most common pancreatic neuroendocrine neoplasms. The incidence in general population is 1-4 per 1 000000 yearly but the incidence is higher in autopsy studies.
  The incidence of insulinomas in the general population is estimated 1-4 per 1 000 000 yearly. The incidence has been reported higher in autopsy studies (0.8% to 10%), (...)
