In this report, the authors investigate and discuss a galactocele that developed in the breast of a 5-month-old male. Based on the histological and immunohistochemical findings, they suggest that the rare and intriguing process that is exclusively observed in males in the absence of any detectable hormonal stimulation at time of investigation could represent a developmental anomaly possibly promoted by an obstructive phenomenon involving a defect of hollowing of some primary epidermal buds, the precursors of the mammary ducts.

Objective: To review standardized Nuss correction of pectus excavatum and vacuum bell treatment over the last 10 years. Summary of Background Data: In 2010, we reported 21 years of the Nuss procedure in 1215 patients. Methods: Over the last 10 years, 2008-2018, we evaluated 1885 pectus excavatum patients. Surgery was indicated for well-defined objective criteria. A consistent operation was performed by 8 surgeons in 1034 patients, median 15 years, (range 6-46); 996 were primary, and 38 redo operations. Surgical patients' mean computed tomography index was 5.46. Mitral valve prolapse was present in 5.4%, Marfan syndrome in 1.1% and scoliosis in 29%. Vacuum bell treatment was introduced for 218 patients who did not meet surgical criteria or were averse to surgery. Results: At primary operation, 1 bar was placed in 49.8%; 2 bars, 49.4%; and 3 bars, 0.7%. There were no deaths. Cardiac perforation occurred in 1 patient who had undergone previous cardiac surgery. Paraplegia after epidural catheter occurred once. Reoperation for bar displacement occurred in 1.8%, hemothorax in 0.3%, and wound infection in 2.9%; 1.4% required surgical drainage. Allergy to stainless steel was identified in 13.7%. A good anatomic outcome was always achieved at bar removal. Recurrence requiring reoperation occurred in 3 primary surgical patients. Two patients developed carinate overcorrection requiring reoperation. Vacuum bell treatment produced better results in younger and less severe cases. Conclusions: A standardized Nuss procedure was performed by multiple surgeons in 1034 patients with good overall safety and results in primary repairs. Vacuum bell treatment is useful.
