7 weeks post op...seroma after tummy tuck? (photo)

Thanks for your question -The firm mass you have is unlikely to be a seroma it is more likely fat necrosis.  You should absolutely continue to have close follow-up with your plastic surgeon to manage both the seroma and this area of firmness.

You should be seen ASAP, the redness that is apparent appears to be infected.  You may have an infected hematoma, since you feel a very hard mass with fluid around it.  Best to be seen and evaluated immediately. Good luck!

From your photographs and your history, it would appear that
you may have a seroma.  The redness that has
been marked out indicate that there may be inflammation there, which could lead
to infection of the seroma fluid.  The
seroma cavity may be loculated (have inner chambers) that may make draining the
fluid completely difficult to do in the office.  In general, if a loculated seroma does not respond to serial aspirations
in the office, it may need to be removed by reopening the incision and cleaning
it out.  I would recommend that you speak
with your plastic surgeon about the possibility of excising the seroma cavity
in the operating room if serial aspiration does not solve the problem.
