[Alopecia totalis, hypotension and erectile dysfunction in a 34 year old patient. Difficult clarification of a common cause].

The occurrence of both autoimmune endocrinopathies and endocrinopathies caused by other reasons is called polyglandular autoimmune syndrome (PAS-syndrome). In a 34 years old man with weakness, weight loss and erectile dysfunction we found low cortisol caused by an autoimmune adrenalitis and low testosterone caused by a hypophysitis with impaired gonadotropin secretion. Thyroid autoantibodies and islet cell autoantibodies without any hormone deficiencies were further signs of a broad endocrine autoimmune syndrome. In the following 11 years the patient developed three autoimmune disorders: paradrenal glandular insufficiency, hypogonadism caused by hypophysitis, Diabetes mellitus type 1. In the same time several non endocrine autoimmune diseases became manifest: alopecia totalis, vitiligo, retrobulbar neuritis and keratoconjunctivitis.
