[Prolactin adenoma developed during puberty. Diagnosis and long-term course. 9 cases].
Nine patients (2 boys, 7 girls) with prolactinomas diagnosed at puberty were followed for 2 to 20 years. The presenting signs were sexual infantilism (n = 2), amenorrhea-galactorrhea (n = 6) and hypogonadism (n = 1). Growth retardation was also present in 3 cases. The pituitary tumor induced endocranial manifestations in only 2 cases, whereas a suprasellar extension was found in 5 cases with visual field defects in 2 cases. Initial prolactin levels ranged between 132 and 2,400 ng/ml and were unresponsive to TRH (n = 6/7). The hormonal work-up showed decreased GH (n = 4/4); LH, FSH (n = 9/9) or ACTH, TSH (n = 1/9) functions. Seven patients underwent trans-sphenoidal adenomectomy associated with dopaminergic agonist treatment. Two patients were treated with bromocriptine. In the long term, clinical signs (n = 6), hyperprolactinemia (n = 7) or prolactinoma (n = 4) persisted or recurred. These data stress the severity of this disease at this period of life, the therapeutic difficulties and the need for long term follow up of these patients.
