Co‐Occurrence of Agminated Lentigines, Café‐Au‐Lait Macules, and Vitiligo: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Lentigines, café‐au‐lait macules (CALMs), and vitiligo are pigmentary disorders that seldom occur together in a single individual. Their co‐occurrence may indicate underlying genetic syndromes requiring differential diagnosis. We report an 18‐year‐old male who developed CALMs at age 11, agminated lentigines at age 13, and vitiligo on the right
