An ulcerated haemangioma over the diaper area can be challenging to manage as you have rightly pointed out that this is an area that is prone to friction and trauma. The ulcer can be become infected or even bleed.
The ulcer should be cleansed gently and you can use the antibiotic ointment over the area. A non-adhesive dressing over the area may be helpful. B
The ulcer is often painful and taking some syrup panadol for pain relief with the dressing changes may be helpful.
If this is persistent or bleeds, you may wish to see a paediatric dermatologist eg. at NSC or KKWCH to see if the underlying haemangioma needs to be treated.
