6 weeks post op lipoma removal on scalp, experiencing recurring swelling (thick blood). Thoughts? (photo)

There is always a possibility that blood has accumulated again under the skin (hematoma). It will need to be drained again. There also could be a leaky blood vessel that might need to be cauterized. RegardsDr.J

Thank you for sharing your question and I am sorry to hear of your healing difficulties.  Unfortunately it appears that you will require another drainage procedure to help speed the healing process.  May want to consider some temporary compression to the area after treatment to help avoid a recurrence.  Hope this helps.

You should return to the surgeon who carried out the surgery or see a suitably qualified and experienced plastic surgeon.Swelling where a lipoma has been removed could be several things. The most likely are a haematoma (collection of blood), less likely seroma (collection of tissue fluid) or possibly pus if it was infected but this unlikely if there are no signs of inflammation on the surface.Best wishes
