Ultrastructural and fluorescence microscopy study of a case of acute erythremia

The authors studies in fluorescence microscopy and electronic microscopy the dysmorphic erythroblasts of a case of acute erythremia. They found evidence of granular fluorescence on the smears, corresponding to the presence of prophyrins and proteinaceous cristallin structures on the ultrathin sections. It seems to be possible to establish a morphologic correlation between the fluorescent granules and the cristallin structures. Thus, the hypothesis of poryphrins adsorption on cristallin structures may be proposed.
