title: [Pituitary adenoma with alpha, 17-39 ACTH and beta, MSH cells, without hypercorticism (author's transl)].
abstract: In one case of pituitary basophil adenoma, the majority of the cells contains numerous small granulations which, by using immunohistoenzymatic technique, react with alpha, 17-39 ACTH and beta, MSH antisera. The reaction with anti beta, 1-24 ACTH is negative. The radioimmunoassay of ACTH reveals an increase of plasmatic ACTH, but the cortisol cycle stays low. This data suggests that this functional adenoma releases a product of which has an immunological relationship with ACTH, without biological activity.
