    Abstract:
    A case of latent Addison's disease accompanied by hypogonadotropic hypogonadism and dwarfism is described. A 20-year-old man was admitted to our department complaining of short stature and immature development of the external genitalia. Pigmentation was most evident on the fingers and face. Endocrinologically, serum ACTH level was very high, and serum cortisol level was in the lower limit of the normal range. Serum aldosterone and adrenal androgen levels were below their normal ranges. Based on these clinical and laboratory findings, the patient was diagnosed as having latent Addison's disease. Serum LH did not respond to a bolus injection of LH-RH. However, after 3 days administration of LH-RH, the response of serum LH to a bolus injection of LH-RH was enhanced. Serum testosterone level was not increased after the administration of hCG. These findings suggested a hypothalamic cause for the hypogonadism. It was indicated that short stature was apparently caused by GH neurosecretory dysfunction, since nocturnal GH secretion was below that in normal males and the response of GH to the administration of arginine was normal. In regard to the thyroid function, the peak of serum TSH after a bolus injection of TRH was delayed compared with normal subjects, and although serum T4 level was high, the basal metabolic rate was very low. This suggests that there is tissue resistance to the elevated thyroid hormone.
