Clinical case of gonadotropinoma, which occurs for a long time under the guise of hyperprolactinemia

Abstract

The prevalence of pituitary adenomas in the population among tumors of the central nervous system is about 17%. Pituitary adenomas are divided into non-functional (about 36–54%), characterized by the absence of secretory activity, and functional (about 46–64%), secreting hormones or their subunits. The most common are prolactinomas (32–51%), somatotropinomas (9– 11%), corticotropinomas (3–6%), the frequency of gonadotropins and thyrotropins is low and amounts to less than 1% of cases. This article presents a clinical observation of a patient with gonadotropinoma, which has been occurring for a long time under the guise of hyperprolactinemia.
