| Sarah Moore, Sanjeev Chunilal, Jacqueline Beerworth |
| Clinics |
| Age and sex : | 84 year(s) old female patient. |
| Previous History : | no preleukemia |
| no previous malignant disease | |
| no inborn condition of note | |
| Organomegaly : | no hepatomegaly ; no splenomegaly ; no enlarged lymph nodes ; no central nervous system involvement |
| Blood |
| WBC : 30.2 x 109/l; Hb : 11.8 g/dl; platelets : 189 x 109/l; |
| Bone marrow : 20% |
| Cyto pathology classification |
| Cytology : (FAB) M2 with maturation; myeloid/stem cell |
| Immunophenotype : CD13+, CD33+, CD7+, CD34+, CD117+, HLA-DR+ |
| Rearranged Ig Tcr : - |
| Pathology : Numerous mononuclear megakaryocytes. Active erythropoiesis. Active granulopoiesis, hypogranular neutrophils, giant band forms, donut nuclei, pseudo Pelger-Huet anomalies. Blasts have moderate nuclear: cytoplasmic ratio. |
| Precise diagnosis : de novo AML with multilineage dysplasia |
| Survival |
| Date of diagnosis: 03-2002 |
| Treatment : Palliative treatment with oral etoposide |
| Complete remission : None |
| Treatment related death : - |
| Status : Dead 07-2002 |
| Survival : 4 month(s) |
| Karyotype |
| Sample : Bone marrow ; culture time : 24 h ; banding : GTL |
| Results : 46,XX,t(4;12)(q11;p13)[15]/46,XX[5] |
 |
| t(4;12)(q11;p13) GTL banded |
| Comments |
| This elderly woman did not receive induction chemotherapy. Her disease rapidly progressed from a smouldering leukaemia to a florid form. Findings are consistent with previous reports of t(4;12) with stem cell leukaemia in older patients, and with rarity of additional cytogenetic changes. |
