The most likely cause of this problem may be fat necosis (a scar tissue nodule formed in reaction to death of fat) from the reduction surgery. Peau d'orange (orange peel skin) is a sign of inflammatory breast cancer which may not be picked up on mammography. You undoubtedly had a pathologic examination of the removed breast tissue from your reduction surgery. I would obtain a copy of this pathology report. This major biopsy of your breast tissue should reveal if there is anything disturbing about the condition of your breast tissue. For further reassurance, you might consider obtaining the opinion of a local general surgeon (pathology report in hand). That surgeon can advise you if a biopsy of the area is warranted. Over the years, I have seen several patients who had similar conditions or lumps post breast reduction. Some of these patients were ultimately seen by a general surgeon who biopsied the tissue. All of these patients turned out to have benign fat necrosis.
thanks!!!
