The McCune-Albright syndrome (MAS) is characterized by a triad of poly/monostotic fibrous dysplasia, café-au-lait macules and hyperfunctioning endocrinopathies including growth hormone (GH) excess. Polyostotic bone lesions and café-au-lait macules are common while monostotic bone lesions are rare. Similarly, acromegaly as a manifestation of endocrine hyperfunction with MAS is uncommon and in most of the instances somatotropinoma has not been documented. We report 3 patients, two of them had monostotic lesion, none had café-au-lait macules and all had GH secreting pituitary macroadenoma. All of them underwent transfrontal pituitary adenomectomy and had histopathological confirmation of GH secreting pituitary adenoma. A brief review of literature is also presented.
