In 1926 M. F. Engman Sr.1 presented before the Chicago Dermatological Society a case of reticular pigmentation of the skin with atrophy. In his description of the case he remarked that the brother of this patient also suffered, but to a lesser degree, from the same condition. These patients have continued under our observation and have submitted to certain studies, which are reported here.
