Acute panmyelosis with myelofibrosis
acute myeloid leukemia characterized by bone marrow fibrosis without preexisting primary myelofibrosis
Acute panmyelosis with myelofibrosis (APMF) is a poorly defined disorder that arises as either a clonal disorder, or following toxic exposure to the bone marrow.
Signs and symptoms
Bone biopsy shows abnormal megakaryocytes, macrocytic erythropoiesis, and defects in neutrophil production and fibrosis of the marrow (myelofibrosis).
Clinically, patients present with reduction in the count of all blood cells (pancytopenia), very few blasts in the peripheral blood, and no or little spleen enlargement (splenomegaly).
Cells are usually CD34 positive.
Prognosis and treatment
Autologous stem cell transplantation has been used in treatment.
Begin with the source’s own compact description: “Acute panmyelosis with myelofibrosis” is acute myeloid leukemia characterized by bone marrow fibrosis without preexisting primary myelofibrosis. The dossier treats that line as a proposition to test through Acute, panmyelosis and myelofibrosis, not as a finished interpretation.
Why this record matters
The phrase “acute myeloid leukemia characterized by bone marrow fibrosis without preexisting primary myelofibrosis” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 27, 2025. The linked authority identifier is Q4677944. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
