Endoscopic extirpation of benign breast tumors using an extramammary approach

Background: Skin incision has been made directly in the breast for treatment of benign breast tumor in spite of the young age of the patient population. Methods: Small incisions (12 mm, 5 mm, and 2 mm) were made in the extramammary line, and the benign tumors (diagnosed by imaging and aspiration needle cytology) were endoscopically extirpated. Results: The mean age of 36 patients was 27.6 years, and the mean mass size was 3.6 cm (7 masses at maximum). The average operation time per mass was 2.6 hours in the first 18 operations and 1.4 hours in the latter 19 operations. Overall blood loss was 19 mL. Postoperative complications were seen in 2 patients: an extended subcutaneous emphysema due to excessive CO₂ gas inflation and a mild burn, both of which were reversible. All patients were extremely satisfied with the cosmetic results of the procedure. Conclusions: Endoscopic removal by the extramammary approach is the best option for benign breast tumors considering the patient's age and the excellent cosmetic results.
