Phyllodes tumor is a rare biphasic neoplastic lesion of the breast composing of stromal and epithelial components.1 Its incidence is 0.3-1% of all the breast tumors.2 It was first described by the name cystosarcoma phyllodes by Mullor which was labeled to the present name by WHO classification in 1982.3,4 It is divided into benign and malignant depending upon stromal and atypical cells.5 About 70-90% of tumors are benign.
To the Editor: Phyllodes tumors are rare fibroepithelial malignancies of the breast and account for <1% of all malignant breast tumors.[1] It is difficult to distinguish from fibroadenomas, while malignant cystosarcoma phyllodes can grow in size quickly and metastasize early.[2] Gigantic cystosarcoma phyllodes of the breast is very rare, thus limiting our understanding of the disease and influencing diagnostic and management outcomes.

Primary osteosarcoma of the breast is a rare and aggressive malignancy that should be differentiated from two other similar tumors: metaplastic carcinoma and cystosarcoma phyllodes.
