Background . Over a 15 year period, the authors followed 51 male patients with myelodysplastic syndromes whose clinical findings, laboratory data, and evolution demonstrated a wide spectrum of disease. Methods . The following characteristics were assessed: age at diagnosis, risk factors, clinical presentation, laboratory features, category of myelodysplasia, leukemia conversion, and overall survival. Results . The clinical manifestations included hemolytic episodes in two patients, antibody‐mediated thrombopenia in one, marked marrow fibrosis in two; thrombocytosis in three, and simultaneous lymphoproliferative disorders in two. There were 21 patients whose marrow was either normo‐ or hypocellular. Six patients presented with single cytopenia but not anemia. There were six instances of overlapping of the French‐American‐British classification. Eighteen patients progressed to acute leukemia and 1 to chronic myelomonocytic leukemia. Conclusions . These observations indicate that patients with myelodysplastic syndromes may have single cytopenia without anemia that progresses to acute leukemia and may, rarely, evolve into chronic myelomonocytic leukemia. The clinical aspects of these syndromes may include autoimmune phenomena and myeloproliferative featu.
