A patient with cleidocranial dysostosis developed extensive pili mulrigemini over the heavily bearded chin and cheek areas. Histological examination of serial sections revealed complicated follicular structures forming from two to as many as eight hair shafts. Each hair is formed by a single branch of dermal papilla which is surrounded by all layers present in a normal follicle except for the outer root sheath cells. The outer root sheath surrounds the entire follicle. Irregularities in configuration of the hairs, longitudinal grooving and areas of bifurcation and re-adhesion of the hair shafts are demonstrated. Pili multigemini is a rare malformation of the pilary apparatus characterized by the presence of bifurcated or multiple divided hair matrices and papillae giving rise to formation of multiple hair shafts within the individual follicles (Flemming, 1883; Giovarmini, 1907,1908,1909,1910). We report a patient with the congenital bony abnormalities of cleidocranial dysostosis developing extensive pili multigemini over the heavily bearded areas of his face. [ABSTRACT FROM AUTHOR] |
