TLDR Isolated patchy heterochromia with pili annulati can occur without other health issues.
The study by Lobato-Berezo, Pesqué, and Pujol (2022) investigates a case of isolated patchy heterochromia with pili annulati features using light and electron microscopy. The findings reveal distinct structural characteristics of the hair, including alternating light and dark bands, which are indicative of pili annulati. This condition was observed without any associated systemic or dermatological disorders, suggesting that it can occur as an isolated phenomenon. The detailed microscopic analysis provided insights into the unique hair shaft abnormalities present in this rare condition.
