Koplik spots
1) First manifestation of measles
2) Rarely seen in measles
3) Are seen 2-3 days after cutaneous rashes
4) Is first manifestation but seldom seen
Oral Pathology
Answer: 4
Koplik spots are first manifestation but seldom seen.
Koplik spots are small, white spots with a bluish-white color that appear on the
inside of the cheek opposite the molars in individuals with measles. They are
considered a pathognomonic sign of measles and typically appear 2-3 days before
the onset of the characteristic skin rash. However, they are not commonly
observed in all cases, making them a less frequently seen early manifestation of
the disease. They are small and can be easily overlooked or mistaken for other
oral conditions.
