Definition:

Pituitary gigantism is very rare conditions resulting from excessive secretion of growth hormone (GH). Most cases are due to benign pituitary adenomas. Nonadenomatous GH excess is exceptional but occasionally occurs in patients with multiple endocrine neoplasia syndrome type 1 (MEN1), Carney complex, or McCune-Albright syndrome. The clinical manifestations may include increased growth velocity with tall stature, enlargement of the hands and feet, excessive perspiration, coarsening of facial features, and headaches. It has been reported that duplication of GPR101 probably causes gigantism and acromegaly. Therapeutic modalities for the treatment of pituitary gigantism include surgery, medication and radiation.
