SECRETING PITUITARY ADENOMAS have marked prevalence in pediatric adenomas. We described a case of an 11-year-old boy with pituitary null cell macroadenoma with silent macroscopic pituitary apoplexy. The patient was admitted with bitemporal hemianopsia and a gradual deterioration of visual acuity. An endocrinological study revealed a low concentration of testosterone and in the plasma a decreased response of luteinizing hormone and follicle-stimulating hormone to luteinizing hormone-releasing hormone. This patient may be the first case of prepubescent null cell macroadenoma confirmed with immunohistochemical study in addition to the findings of classical histopathology.
