Popis: | We retrospectively report data on 28 patients with haematological malignancy and trisomy 13 (25 cases) or tetrasomy 13 (three cases) as the primary acquired cytogenetic change. Peripheral blood and/or bone marrow morphology was reviewed in 25/28 cases and the final diagnosis was as follows: AML M0 (11), AML M1 (6), AML M2 (2), AML M4 (2), AML M5b (1), AML M6 (1), RAEB-t (3), RAEB (1), RA (1). All three cases with tetrasomy 13 had AML M0. Characteristic small hand-mirror blasts with cytoplasmic blebs and tails and scanty small granules were seen in 13/25 cases and 18/25 cases had small blasts which could easily be mistaken for lymphoblasts. Trilineage dysplasia was present in 8/28 cases. Median patient survival was 3 months. We conclude that trisomy 13 is particularly associated with acute myeloid leukaemia with minimal differentiation (AML MO), often has distinctive morphological features, and has a poor prognosis. |
