We report 3 cases of Albright's syndrome consisting of the triad of polyostotic fibrous dysplasia, cafe au lait spots and various endocrinal abnormalities, which were encountered in the period from 1980 to 1989. There were 2 males and 1 female, with age ranging from 35 to 48 y/o. All of them had polyostotic fibrous dysplasia mainly involving thoracic cage and femoral bone, pigmented skin spots, and endocrine disorder. Two had hypogonadism which was not commonly reported. It is our purpose to bring up the possibility of Albright's syndrome as a differential diagnosis when polyostotic fibrous dysplasia is seen.
