GARCIA GARCIA, E. et al. Prolactinoma: a diagnosis to be taken into account in children with pituitary neoplasms. Rev Pediatr Aten Primaria [online]. 2009, vol.11, n.44, pp.607-612. ISSN 1139-7632.

Pituitary adenomas are rare in childhood and adolescence and half of them are prolactinomas. In this report, we present a 13-year-old boy with a sellar and suprasellar cystic lesion treated with surgery; afterwards, histopathological and immunohistochemical examinations revealed a prolactinoma. Cystic macroprolactinomas are extremely rare in prepuberty, nevertheless they have been reported from the age of 9 years. The differential diagnosis with cystic craniopharyngioma is important, as treatment with dopamine-agonists may be the first choice in prolatinomas, whereas a transcranial surgery is required for a suprasellar craniopharyngioma.
