Phyllodes tumors are rare fibroepithelial lesions that count for 0.3-1% of all primary breast tumors.
Telling the difference between phyllodes tumors and giant juvenile fibroadenomas, that rarely affect adolescent and young women, is difficult but of importance because resection with margins is the mainstay of treatment for phyllodes tumors.
We report a clinical case of an eighteen-year-old female patient, with past history of left breast lump excision four years before, classified as “juvenile fibroadenoma”.
In early 2015, she was referred to the consultation by the appearance of a bulky ipsilateral lump (10.8 x 6.9 cm), core-biopsy histology revealed “fibroadenoma with more lax stroma vs benign phyllodes tumor”. Surgical excision of the lesion was performed.
Histology of the specimen confirmed “benign phyllodes breast tumor (14 x 12 x 8 cm and 788 g)”. Given its benign nature and negative margins, the patient did not require further treatment and currently attends in follow-up consultation.
A brief discussion of this rare form of fibroepithelial tumor, minding its classification, diagnosis, treatment, followup and prognosis is done.
