Tinea Versicolor
by UncleJack5, May 02, 2005 12:00AM
Hello.
This past summer I was very tan from alot of sun exposure.
However, towards the end of the summer I noticed a rather large
white "patch" in the middle of my chest. It looked very strange because the rest of my body was tan except for this white patch. I have since lost my tan because I have not had much sun exposure during the fall and winter months. However, the whiteness still remains. There are many white
blothces in the middle of my chest. Often, when my body temp rises, especially when I sweat due to working, these white blotches turn into red blothces about 24-48 hours after profuse sweating. My dermatologist just diagnosed the white blotches as tinea versicolor and prescribed me shampoos and a cream (not sure of the exact names). He also stated that the white blotches turning red 24-48 hours after a lot of sweating is completely normal for tinea versicolor. It is quite embarrasing having these red blotches on my chest. After a few days, the redness does goes away, but the white blotches remain. I am concerned, and I would appreciate your opinion that it is normal for these white blotchs to turn red after increased body temp due to sweating. Thank you very much.

I agree with your dermatologist--the lack of pigment lets you see the blood vessels more clearly when they open up, as they do after exercise, for instance. Fortunately, the pigment change is temporary in tinea versicolor. The treatment will kill the fungus, and then it's just a matter of time (generally a few months) for the color to return. If you get more white spots in the future, which is likely at some point, it's best to treat them right away, so they won't hang around.
Best.

on my chest are actually blood vessels? And does it sound normal that the red blotches stay for 4-5 days and then fade
back into white blotches?
Thank you.

It's white spots that grow if left untreated, when treated with the liquid sold in pharmacies here, it leaves a dry skin which rubs off. the natural skin colour returns after a while.
