so what i want from you after you see these images are :

1- Put your diagnosis and why ?
2-Look at the left image and :
-Describe what do you see
-what do we call it?
-is it pathognomonic sign?
-when does it appear and what is its importance ?

see these images

mmmm let's see

1-I think it is measles
we can see wide-spread rash in a child...
2- and in the second picture we can see a characteristic sign for measles which is Koplik´s spots which appear before the rash
(Koplik´s spots are a white macules in the mucous mambrane of the mouth)
