title: [Myelodysplastic syndrome in a patient with familial Pelger-Huet anomaly].
abstract: This paper reports on a patients with congenital Pelger-Huet anomaly who developed myelodysplastic syndrome (MDS). A 45-year-old female was referred for investigation of pancytopenia of 6 months' duration. Hereditary Pelger-Huet anomaly was diagnosed by family study 7 years prior to admission. On admission, Hb was 6.5 g/dl, Ht 19.9%, Platelets 1.8 x 10(4)/microliters, and WBC 1,200/microliters with 2% myelocytes, 9% metamyelocytes, 14% bands, 2% segmented neutrophils, 58% lymphocytes and 5% monocytes. Most of the granulocytes were Pelger-Huet type with strikingly clumped nuclear chromatin. Bone marrow aspirate demonstrated 3.6% blasts and dysplastic changes including megaloblastoid features in erythroid series and micro-megakaryocytes compatible with refractory anemia, a subtype of MDS. The association of hereditary Pelger-Huet anomaly and MDS is discussed.
