A curvilinear incision was made directly over the mass in the upper-outer quadrant of the right breast.  Dissection was carried out around a firm mass, which was dissected with surrounding margins of breast tissue.  Hemostasis was obtained using electrocautery.  Frozen section exam showed a fibroadenoma with some proliferative hyperplasia within the fibroadenoma, but appeared benign.  The breast tissues were approximated using 4-0 Vicryl.  The skin was closed using 5-0 Vicryl running subcuticular stitches.  A sterile bandage was applied.
