It certainly is possible that this blue lesion growing on your abdomen could be a recurrence of the hemangioma, especially if it is growing at exactly the same spot as the previous lesion. So I I would recommend evaluation by your dermatologist
or primary care doctor
as soon as possible.
However, I think the more concerning possibility that needs to be ruled out right away is that this is actually a more serious skin growth. In particular, ruling out that this is a melanoma, a serious form of skin cancer, needs to be prioritized. Signs that would be more concerning for melanoma would include an irregular border or shape, variations in color within the spot, or rapidly growing. The size of the spot is already concerning enough, that I would recommend evaluation by your dermatologist or primary care doctor as soon as possible.
After your doctor takes a look at the lesion, they may decide that ruling out melanoma is needed. If so, this will require a repeat biopsy
, which will probably be similar to the procedure that you already had to remove the hemangioma. In the case of suspected melanoma, the entire spot is usually removed rather than just a small sample.
Call and make an appointment with your doctor as soon as you are able to do so!
