Hormonal receptors of giant cell tumors (GCTs) have not been previously reported. Five cases of GCT of bone were analyzed for estrogen and progesterone binding. Frozen sections were studied by a histochemical method, using 17-beta-6-CMOBSA-FITC and 11-alpha-hydroxyprogesterone-HS-BSA-TMRITC. Cytoplasmic fluorescence with

The present study defines criteria for determining the presence of estrogen-receptors in human breast carcinomas demonstrated by a histochemical assay using 17 beta-estradiol-carboxy-methyl-oxim-bovine serum albumen-FITC. The criteria were: 1) the percentage of cells showing fluorescence; 2) the intensity of the
