Abstract
A 59-year-old female patient with type 2 diabetes mellitus, chronic bone pain and hyperthyroidism without treatment, as well as multiple fractures since childhood, early puberty and recently diagnosed intramuscular myxoma, was admitted to internal medicine unit to establish a clinical syndrome. Imaging and nuclear medicine studies were carried out and polyostotic fibrous dysplasia was documented, which in association with intramuscular myxoma are characteristic of Mazabraud's syndrome. In addition, the correlation between precocious puberty, endocrine dysfunction and a single café-au-lait spot on the back was made, which allowed establishing the clinical diagnosis of McCune-Albright syndrome. The case of the association of these two rare syndromes is presented.
