The use of Congo red as an elective stain for eosinophilic granulocytes and their precursors
in tissue sections and autoradiographs is demonstrated and discussed. The 0.5% alcoholic
Congo red solution of Highman, normally used for the detection of amyloid, may also be
used with only minor changes. This simple method may aid in the diagnosis of special
hematological problems and facilitates the recognition of eosinophil granulocytes as well as
proliferating and nonproliferating myelocytes in autoradiographs from paraffin sections.
