Acromegalia que simula un neuroblastoma

Endocrinology is a specialty that, to a large extent, lacks specific diagnostic tools. Endocrinologists are characterized by their ability to interpret basal and stimulated hormonal data. We describe the case of a male patient initially diagnosed as suffering from an olfactory neuroblastoma with ectopic prolactin secretion, based on histological and radiological studies. After a review of all the clinical and hormonal results, the tumor was finally diagnosed as a growth hormone (GH)- and prolactinsecreting pituitary macroadenoma. In summary, pituitary adenomas that secrete GH and prolactin can sometimes simulate other tumors, especially when hormonal results are not interpreted correctly.
