Should I be worried. Has this skin graft failed? 2 weeks post breast reconstruction with mastectomy. (photos)

Dear brookl1,it is hard to tell for sure without an examination. I would suggest you to consult your plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS

HiThanks for your question and sharing your photos.Viability of nipple grafts is hard to determine in pigmented skin but they do look ok to me. You should expect the epidermis to peel shortly while the dermis remains and takes on a light pink color. Pls keep grafts clean by washing with soap and water then patting dry and lightly applying antibiotic ointment or Vaseline. Pls follow up closely with your PS.I hope this helps.....

Thank you for the question.  Unfortunately, it is difficult to determine the viability of the left nipple skin graft.    Would talk with your plastic surgeon, have him/her evaluate it and make any treatment recommendations.   Best of luck on your recovery.
