ObjectiveTo discuss the method and significance of concentric circumareolar approach in treatment of gynecomastia.MethodsThe incision was designed with the patient in a standing position.The location of the new nipple was determined,around which a outer cycle with the diameter of 5 cm was marked.And then a concentric inner circle with the diameter of 2.5 -3 cm was marked around the original nipple.The bilateral nipple position should be on the same level.A rim of tissue around the nipple-areola complex( NAC )was deepithelialized,excision of excess glandular tissue was performed subcutaneously and vascular network of dermis was preserved as much as possible.The purse string suture was applied in the circumareolar incision.Results 30 patients with gynecomastia were treated with this method.The result of the operation was pleasing with good aesthetic appearance,normal blood supply,and inconspicuous scars.Conclusion As a surgical approach of gynaecomastia,concentric circumareolar incision can remove excess glandular tissues and redundant skin,and has the benefit of concealing incision,simple procedure and satisfactory outcome.

ObjectiveTo evaluate the diagnosis and surgical management of non-palpable breast cancer (NPBC). MethodsDiagnosis, preoperative localization and surgical management of 26 cases of NPBC were analyzed retrospectively.ResultsAll the 26 lesions were found by ultrasound or mammography.Local-extensive excision was performed under preoperative ultrasound-guided or radio-guided wire localization.Of the 26 lesions, 14 were ductal carcinoma in situ (DCIS), 9 were DCIS with micro-invasion and 3 were invasive ductal carcinoma.ConclusionsCombination of ultrasound and mammography improves the discovery rate of NPBC.Local-extensive excision under preoperative ultrasound-guided or radio-guided wire localization of NPBC shortens the duration of surgical procedure, avoids excessive resection of breast tissues and maintains the apperance of the breast.
