Bilateral benign phyllodes tumour in a nulliparous woman: a case report and review of literature.

Cystosarcoma Phyllodes is an uncommon disease of the breast with variable clinical behaviour. Its incidence is reported as 1% of all breast tumours. The occurrence of bilateral disease is very rare. In this communication, we present a case of metachronous bilateral benign cystosarcoma phyllodes presenting in a 24year old nulliparous lady. She had right breast mastectomy after two recurrences following local excision. The left breast lesion developed one year after the treatment of the right lesion, again she had to be treated with mastectomy after 2 recurrences. This case unlike most reported cases of bilateral Phyllodes tumour occurred in a nulliparous lady. The problems of diagnosis, clinical behaviour and management are discussed.
