First of all height has nothing to do with this kind of a presentation.
Commenting first on the vagina appearing to be white, this could be a yeast infection and will have to be confirmed by a doctor through a physical examination and laboratory investigations. Treatment will be directed according to the test reports.
As for the white spots
all over her body, this could be related to various skin associated conditions, I would recommend a visit to the skin specialist without further ado, as I will not be able to comment on the possible causes without looking at the lesions myself.
Hope this helps.
