Endoscopic-assisted transaxillary removal of a midline anterior epidermoid cyst

A 3-year-old boy presented with a 3×3 cm dermoid cyst in the midline of the anterior chest wall. Thiswas successfully removed, using an endoscopic-assisted technique, through a single incision placed in the anterior axillary fold, avoiding the need for a mid-sternal incision. This technique and its application to paediatric soft-tissue surgery are discussed.
