[38 year-old patient with suspected congenital hormonal dysfunction].

We present the case of a patient with suspected congenital hypopituitarism first diagnosed at the age of 38 years. Despite partial insufficiency of all pituitary-regulated hormonal axes, the patient never suffered from severe health problems. However, the patient was disfigured, and his intellectual and physical capacities were clearly impaired. The initiation of a hormone replacement therapy with hydrocortisone and thyroid hormones is essential in such a patient, but the substitution of sex hormones can create ethical problems.
