A 3-year-old boy presented with a 3 x 3 cm dermoid cyst in the midline of t
he anterior chest wall. This was successfully removed, using an endoscopic-
assisted technique, through a single incision placed in the anterior axilla
ry fold, avoiding the need for a mid-sternal incision. This technique and i
ts application to paediatric soft-tissue surgery are discussed. (C) 2001 Th
