"   Question I have been unable to find any information about a condition called hemihypertrophy.  Any information that you could pass on to me would be greatly appreciated.   Answer Hemihypertrophy is a rare congenital condition that is found either as an isolated feature, or associated with one of a number of so called &amp;#039;overgrowth syndromes&amp;#039;.  Hemihypertrophy is an example of hemi-asymmetry, where part or all of one half of the body is enlarged, affecting multiple tissues on a primary basis.  Additional features vary according to which overgrowth syndrome is present. One such example is Beckwith-Wiedemann syndrome, a congenital overgrowth syndrome with variable expression, that occurs with an incidence of one in 13,700 births.  Most cases occur sporadically, but approximately 15% are familial.  The major features are abdominal wall defects, enlarged tongue (macroglossia), and large birth weight or postnatal growth. Less common features are low blood sugar in infancy, organ enlargement, congenital kidney anomalies and a predisposition to the development of tumours affecting embryonic tissue.  Other very rare congenital overgrowth syndromes that have been reported to feature hemihypertrophy include:   Macrocephaly-cutis marmorata telangiectatica congenita. Klippel-Trenaunay-Weber syndrome. Proteus syndrome.  Hemihypertrophy is linked to a variety of benign and malignant disorders that usually appear during childhood, but can develop later in life.  These disorders include cancer of the adrenal glands and liver.  Yours sincerely The NetDoctor Medical Team  Other Qs &amp;amp;amp; As Can an underactive thyroid exacerbate allergies?
