Peculiar distribution of comedones: a report of three cases.
Three cases in which comedones developed in three different peculiar patterns are presented. Comedones developed along the stria nasi, the creases of the forehead and the ear lobule in a girl aged 14 and 2 men aged 73 and 72 years, respectively. A parallelism with keratosis punctata of the palmar creases is proposed. Some anatomical locations seem to facilitate the development of comedones in preexisting pilosebaceous units showing an apparently artificial pattern.
