-
- Froelich's syndrome, or adiposogenital dystrophy, is characterized by
- delayed puberty, small testes in males, and obesity. It affects primarily
- males. In recent years, Froelich's syndrome has come to refer exclusively to
- such features in boys who have lesions in the hypothalamic region of the
- brain. (Different parts of the hypothalamus control sexual development and
- appetite.) Teenagers with this disorder must be differentiated from those who
- simply have a familial trait of slower than normal growth or Prader-Willi
- Syndrome.
-
- Symptoms
-
- Puberty is considered delayed if the external genitalia fail to enlarge
- normally by about the age of thirteen and a half, or if the period between
- the beginning and the completion of the growth of the genitalia (in girls,
- breast development and the first menstruation) takes longer than 5 years.
-
- In Froelich's Syndrome, obesity accompanies such a delay. Body growth
- may also be slow, and patients often remain short in stature. Secondary
- sexual characteristics such as facial and body hair, voice changes,
- coarsening of the skin, etc., appear very slowly. Finger nails are often
- malformed or undersized. Headaches are common. Some patients may have mental
- retardation, visual disturbances, and, rarely, diabetes mellitus.
-
- Causes
-
- In some cases, the anterior pituitary, an endocrine gland attached to the
- brain, fails to secrete the hormones necessary for puberty to proceed because
- of some lesion to the gland. Froelich's syndrome is due to lesions in the
- hypothalamus, one part of which produces substances that stimulate the
- pituitary; another area of the hypothalamus is believed to regulate the
- appetite. Tumors and inflammation due to infections such as tuberculosis or
- encephalitis usually cause the lesions.
-
- Related Disorders
-
- Hypogonadotropic hypogonadism is a disorder of development of the region of
- the hypothalamus that regulates the pituitary hormones (gonadotropins) that
- in turn regulate the functioning of the gonads. In the congenital Laurence-
- Moon-Biedl syndrome, the child has defects in the ears and/or eyes, mental
- retardation, anomalies of the fingers and toes, obesity, and underdevelopment
- of the genitalia. In Prader-Willi syndrome, also congenital, neurological
- and behavioral abnormalities accompany hypogonadism and obesity. (For more
- information on these disorders, choose "Laurence-Moon" and "Prader-Willi" as
- your search terms in the Rare Disease Database).
-
- Therapies: Standard
-
- Pituitary extracts may be administered to replace the missing hormones in
- patients with Froelich's Syndrome. Hypothalamic tumors should be removed if
- possible, although this will not restore destroyed tissue. Appetite may be
- very difficult to manage, although weight control depends on this.
-
- Therapies: Investigational
