SEVERAL recent reviews of the literature on colloid milium by Robinson and Tasker,1 Reuter and Becker,2 Way3 and others make it inappropriate to include a complete review in this report. Gilbert and Cox,4 both of the Australian Army Medical Corps, reported 8 cases of colloid degeneration observed at an Australian general hospital. They stated the belief that sunlight is an important factor in the etiology of this condition. While the theory was expressed by Anderson,5 Way and others that a vitamin deficiency may exist and that it may be an etiologic factor in the development of colloid milium, there is not an unanimity of opinion as to the etiology of this condition. In the 2 patients whose cases I report here, the question of vitamin C as an etiologic factor is problematic. Both patients enjoyed good health, and their economic status was better than average.
