Acquired refractory anaemia with excess of blasts of promegakaryoblastic type.

A case of acquired refractory anaemia with excess of blasts (RAEB) of the promegakaryoblastic type is described. The promegakaryoblastic origin was demonstrated by means of ultrastructural cytochemistry (platelet peroxidase) and immunological methods. The blasts were also 5'-Nucleotidase positive. After a stable course over 2.5 years the patient died from hematological failure, his marrow demonstrating a high degree of fibrosis.

Cytochemical detection of erythroblastic enzymes in acquired dyserythropoiesis.

We have studied the amount and intracellular distribution of erythroblastic alkaline and acid phosphatase, nonspecific esterase, and N-acetyl-beta-glucosaminidase in 50 patients with acquired dyserythropoiesis. 19 morphologically normal bone marrow smears served as controls. Alkaline phosphatase was found in all controls (mean 9.4% of erythroblasts). The percentage of positive erythroblasts in pathological conditions varied greatly from absence to over 70%. Acid phosphatase and N-acetyl-beta-glucosaminidase were positive in pernicious anaemia and in acute erythremic myelosis. Nonspecific esterase was only detected in a case of erythremic myelosis. This case also showed a faint metachromasia with the dye azure A.
