My tummy tuck scar has a tiny hole and this morning I noticed that is draining pus. Could it be a sign of gangrene? (Photo)

Hi, there.  Based on your photos, you might have had a suture abscess.  Depending on which suture was used to close your incision, it may take 4-6 months for the suture to dissolve.  If the suture works its way out, it creates a small abscess and irritates the skin around it.  You can apply antibiotic ointment.  But please visit with your plastic surgeon to be evaluated in-person.  In regards to coloration of scar, it will improve with time.  Follow your plastic surgeon's post-operative recommendation.  I usually provide a scar cream once the incision is healed and ask my patients to avoid Sun exposure.  Best regards.

Thank you for your question. If draining a pus you need to contact your surgeon. It is more look like a healing issues possibly stitch abscess, which can be treated easily in the office. Pl talk to your PS . Good luck with your healing.
