Transnipple pyramidectomy in pathological nipple discharge: an original minimal surgery technique in a series of 80...

Pathologic nipple discharge presents a diagnostic dilemma as no one diagnostic test has proven clearly superior to any other in the differentiation of benign versus malignant conditions. This is a clinical study of 80 patients with unilateral suspicious nipple discharge whose complete investigation included histological evaluation. A transnipple approach was used to identify, get to and excise the breast tissue suspicious of having caused the pathological discharge, with a pyramide-shaped tissue dissection (pyramidectomy). Specimens satisfactory for histological evaluation were obtained in all cases. Breast cancer was detected in six cases, papillomatosis in four, papillomas in 30, fibrocystic changes in five, ductal ectasia in 31 and non specific findings in four cases. There were no intraoperative complications and functional and healing-esthetic recovery was very good in all cases. It is concluded that transnipple pyramidectomy is a useful technique for a reliable diagnosis of pathologic nipple discharge.
