1 Introduction Cutaneous Pili Migrans, first described by Yaffee in 1957, is a rare condition characterized by a creeping eruption caused by the intradermal migration of a hair shaft [1]. It most commonly occurs on the feet and presents as a linear or wavy black track [2]. Involvement of the scrotum is exceedingly rare, and an annular presentation has never been documented.

To the Editor: Millipedes do not have nearly as many feet as their name would suggest; most have fewer than 100.1 They are not actually insects; they are a wormlike arthropod in the Diplopoda class.
