Brief Answer:
more case details and photograph required.

Detailed Answer:
Hello,

Thanks for writing to health care magic.

It is a good thing that you are interested in discussing your sisters skin problem here.

But information provided by you is not sufficient and can not point out any particular diagnosis.

I request you to send following details,

1.Duration of the lesions(days/months/year)

2.Lesions on other part of body such as face,scalp,mouth etc.

3Appearance of blisters (fluid filled/pus filled/red/ etc)

4.Any treatment she has received from any doctor for this condition.

This details along with photograph if possible will help in making out a diagnosis and further plans for treatment.

There is a facility available in this forum for uploading a photograph.

I hope we can continue our discussion once you send details.

Take care.
