AbstractGrowth hormone (GH) secreting adenoma represents a therapeutic challenge in childhood. Because of its rarity no treatment guidelines are available and pediatric management often results from recommendations issued for adults. We report a case of a 4-year-old girl with somatotropinoma successfully treated with only medical treatment. She presented with tall stature and history of growth acceleration. Imaging and laboratory confirmed the diagnosis of GH secreting macroadenoma. She started medical treatment with a somatostatin analogue and a dopamine agonist. During an 8-year follow-up period, a good clinical control of the disease and a shrinkage of the adenoma have been demonstrated. At the last observation she achieved normal near-adult height and pubertal development. According to our experience and limited literature evidences, first line treatment with somatostatin analogues can be attempted in patients with somatotropinoma. This approach seems to be able to control the clinical course of the disease, allowing to postpone transphenoidal surgery to adult age or to avoid it.
