Striae Distensae, Familial

Clinical Features

McKusick (1971) observed transverse striae of the lumbar area in father and 2 sons. The striae appeared in their teens and faded as they grew older. Carr and Hamilton (1969) noted that such striae are more common in males. Weber (1935, 1935) called them idiopathic striae atrophicae of puberty. Striae distensae occur, especially in the deltoid, pectoral, hip and thigh areas, in the Marfan syndrome (154700) and there are sometimes very striking transverse striae in the lumbar area identical to those seen on an apparently idiopathic basis.
