Exactly.....
Tinea Versicolor... also called Pityriasis Versicolor, this white spot disorder is caused primarily by an over production of a fungus, a type of yeast called pityrosporum orbiculare. This bacteria is a normal part of the skin flora (bacteria mix). This microscopic fungus flakes off of the scalp onto the upper body, just like dandruff, and remains unnoticed until a person starts to tan. Unfortunately, tanning is prevented in areas where it lands because this fungus produces a chemical that prevents melanocytes from producing melanin. The condition spreads more easily in hot, humid environments. One treatment is to use extra strength dandruff shampoos that have selenium sulfid in their ingredients. These products must be used consistently in order to be effective. Does it cause sun sensitivity.....no.... but until you have it nipped in the bud, you will have white spots in those areas. Also wear light, loose clothing to avoid sweat in those areas. You didnt mention where you live.
