Hi,
Noted the history about your neighbour developing ulcer like things on mon pubis and face.
The commonest causes I can think about are as follows:
Scabies is one of the commonest reasons to have such things but not known to occur on face hence may not be possible diagnosis
Dermatitis with secondary infection can cause as you have described about scabs on face.
Seborrhoic dermatitis can present in similar ways.
I would advise you the following in such a situation:
Consult a Dermatologist for proper clinical diagnosis and have proper management as advised.
Till you get an appointment for her do the following:
Apply Liquid
povidone iodine locally to the affected area.
Take an anti-inflammatory like
Ibuprofen if it suit her.
Take multivitamins and mineral with sufficient quantity of
Vitamin A and D as these helps for better skin results.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, General Surgeon
