Ecker has specially pointed out, appear to be due to a temporary 
arrest in the development of the hairy covering, and the persistence 
and subsequent growth in post-embryonic life of the foetal woolly 
covering or lanugo. Wecan describe this as Pseudohypertrichosis

red edges of the lps, was thickly covered with delicate, soft, 
and partly curly hair, such as also projected from the orifices 
of the ears and nose. The body of the Russian was somewhat

(¢.g. retarded puberty) not infrequently occur.
