A CASE OF GIANT PHYLLODES TUMOR IN A 14-YEAR-OLD GIRL

Abstract

A 14-year-old girl was referred to the hospital because of a painless tumor of the left breast. About 4 months before the referral, she began to feel a swelling of the left breast but left it alone; she visited another hospital because the tumor gradually enlarged. On admission, a 12.5×10.5cm elastic soft and well defined tumor was palpated in the left breast and an elastic hard lymph node in her left axillary region. The tumor was diagnosed as phyllodes tumor because of multinodular figure by ultrasonography and enhancement in an early phase by dynamic magnetic resonance imaging and was resected by an enucleation with a little normal gland. Histological examination revealed that the tumor was benign phyllodes tumor 12.5×11.0×6.5cm in size and 400g in weight and no maligant finding were found in the lymph node. No signs of recurrence have been recognized 4 years after the surgery. Although the standard surgical treatment for phyllodes tumors has not been established as yet, wide excision with marginal normal gland is enough for benign phyllodes tumors. Normal gland should be conserved as much as possible and lymph node dissection should be avoided especially in early teens as shown in this present case.
