My daughter is seven years old and last August I noticed some hypopigmented areas on her knuckles. She also has a small patch on her wrist and one on her ankles. Immediately I rushed assuming it was vitiligo. Three doctors have examined her since then, in October, December and March with a wood;s lamp. All wood's lamp examinations have been negative. The spots do not flourensce. The Dr.'s claim she has pigment, just a lighter shade then her skin. They showed me an example of lint under the wood's lamp to show me what vitiligo would loook like. The lint glowed blue-white as oppose to her spots which look a lighter shade of beige than her regular skin. I asked for a biopsy and the said that the biopsy would show pigmet, therfore a negative vitiligo diagnosis.
Dr. I wish to believe them, however, I the research I conduct shows the areas of her hypopigmentation to be the exact areas where her marks are.
Can these marks be something other than vitiligo? Her dx: is post-inflammatory hypopigmentation. Also, luckily, she is very fair skinned and I apply sunblock daily also locoid cream. I have seen complete repigmentation on three spots, however, I see two new ones.
Are three wood's lamp examinations within six months enough to rule out vitiligo???
Also, I am concerned as the last examination was done with the light on. That's were she showed me the difference between the glowing lint and her spots.
Dr. Please help
