Can chickenpox start out on the area near navel of a child?

Possible: The rash usually starts on the trunk and spreads to head (face and scalp). It begins with crops of red bumps which rapidly become little fluid-filled blisters which do not have an indentation in the center. Children usually first have fever, malaise, and loss of appetite about a day before the rash begins. The rash continues in new crops of lesions for 3-4 days. They itch and may be in mouth.

The first...: ...Lesion can be anywhere, but if there are more than 3 lesions and they are all clustered together, chickenpox would not be my first choice.
