Hi, Sounds like we are in the exact same situation. My daughter is 8 weeks with an ulcerated lower lip H. I just took her to the doctor yesterday. The ulceration is on the outer lip border. There has been no bleeding, but it looks like a hole. The doctor told me to use polysporin on the area and swabbed it to check for infection. She told me if it does not go away within the next 7-10 days that she will prescribe a stronger medicated ointment. I have only put on two applications, but the ulcerated area appears to look slightly better. The doctor also mentioned steriod injections if it gets worse. Hope that helps.
I was curious if your doctor has talked to you about using Timolol (topical propanolol)? My daughter has been on it since she was three weeks old. Our doctor told us that the topical medicine has the best results for lip and eye lid hemangiomas because the skin is thinner in those areas. I feel comfortable with the medicine because it is topical and does not have any known adverse side effects. The medicine obviously didn't stop the ulceration, but it has stunted the growth of her H. Please keep us updated!
