Is this a fungus on my nipple 5 month post breast reduction? (photos)

Thank you for your pictures. It is impossible to diagnose this type of thing from a photo. I suggest you see your surgeon for an exam and possible biopsy of the area to be sure.Good luck!Dallas R. Buchanan, MD, FACSOwner & Board-Certified Plastic SurgeonVIVIFY plastic surgery

Your photo is very helpful.  You need to go back to your plastic surgeon for help.  They may organise a consultation with a dermatologist for you if they cannot help.  Best wishes.

Why are you not seeing your operative surgeon for care? Or seek finding a second opinion and care providing PS. Expect the second PS to charge a fee to be seen and to render care. Also see a dermatologist for any skin issues...
