Brief Answer:
could be vitiligo

Detailed Answer:
Hi,
Thanks for writing to us.
From the description it seems your child could be having a single lesion of vitiligo.
Your doctor must have advised a steroid injection to induce pigmentation and control disease activity.
I would appreciate if you could attach an image of the lesion, so that i can confirm diagnosis and suggest an effective treatment.
You may upload the pic by clicking on upload report/image icon which is on right side of query page.

Hoping to hear from you soon.
Take care

Detailed Answer:
Hi,
Thanks for sending the pic.
Though the image is not very clear but a small white spot can be seen.
It looks like vitiligo lesion but you need not worry.
Right now I would suggest that you use a potent steroid like clobetasol cream once in a day over affected area and tacrolimus 0.03% ointment twice in a day. If at all lesions seems to be increasing in number or size then we will start oral medicines. Personally I feel we can delay injection for few weeks as the lesion should respond to topical treatment alone.
hope this helped.
Take care
