The management of adolescent females with giant cystosarcoma phylloide
s remains controversial. Since in this age group the overwhelming majo
rity of these neoplasms are benign, aesthetic outcome is as important
as adequate tumor resection. Traditionally, treatment has been wide lo
cal excision, which may lead to substantial breast deformity. In addit
ion, inadequate planning with improper incision placement may result i
n visible scarring and impair immediate or subsequent breast reconstru
ction. The treatment of four adolescent females with large breast mass
es using breast-sparing techniques is discussed.
