Koplik spots

Full Definition

Koplik spots are characteristic enanthem findings that appear as small white or bluish-white spots surrounded by red halos on the buccal mucosa, typically opposite the molars. These lesions are pathognomonic for measles (rubeola) and typically appear 1-2 days before the characteristic rash develops. First described by American pediatrician Henry Koplik in 1896, these spots are considered one of the most reliable early signs of measles infection and are crucial for early diagnosis in clinical practice.

Usage
