title: Congenital hypothyroidism in a young man with growth hormone, thyrotropin, and prolactin deficiencies.
abstract: A growth-retarded, mentally deficient, young man is described with diminished secretory response of growth hormone, thyrotropin, and prolactin to the pharmacologic stimuli of insulin, arginine, chlorpromazine, and thyrotropin-releasing hormone. Gonadotropin and ACTH functions were normal both basically and upon pharmacologic stimulation. Additionally, the patient was unresponsive to exogenous thyrotropin injections. These data suggest that the hypothyroidism in this patient was due to combined thyroid dysgenesis and pituitary insufficiency, i.e., primary and secondary hypothyroidism.
