[Pili multigemini: a pilar dysplasia with linear disposition].
BACKGROUND
Pili multigemini is an uncommon pilar dysplasia with linear disposition which could be explained by the pattern of Blaschko's lines.


METHODS
A 37-year-old man with no medical history developed pili multigemini over a heavily bearded chin.


CONCLUSIONS
Mili multigemini is an uncommon developmental defect of hair follicles resulting from hairs with multiple matrices and papillae emerging through a single pilosebaceous canal. This defect has a linear distribution on the chin we found to follow Blaschko's lines. Pili multigemini has been observed in association with a few rare malformations. Treatment is difficult.
