Conversation: The conversation between human and AI assistant.
[|Human|] My daughter, age 12 has an area on her lower back which began around first of May and about the size of a dime when we noticed it, and thought it was a bruise. The area kept getting bigger and is now approx 20mm x 40mm and is not a bruise. I took her to the pediatrician who said it was a skin issue and not spinal. The area does appear to be of different texture with no hair on this spot. The color is a brownish-grayish-bluish. She has some back ache, but the pediatrician said was just coincidental. Made an appointment w/dermatologist. Just worried about what it might be.
