Phyllodes tumor of the breast is a benign newgrowth of the breast which usually rapidly increases in size. The mass usually contains fleshy and cystic areas which have led to its original name being used (cystosarcoma phyllodes – cysto = cystic areas; sarcoma = fleshy areas). There are usually no associated axillary lymph nodes despite its huge size. A wide excision is the treatment of choice. Depending on the size of the phyllodes at the time of treatment, the wide excision may entail a subtotal or a total mastectomy.
