Recurrent phyllodes tumor of the breast transforming to a fibrosarcoma

Abstract: Phyllodes tumors are fibroepithelial tumors of the breast, representing 2-3% of all fibroepithelial tumors, and <1% of all breast tumors. Malignant transformation may occur usually within stromal component of phyllodes tumor. Careful characterization of the stromal compartment is critical, since it is the pathologic features of stromal cells that determine its malignant potential. Primary sarcomas of the breast are extremely rare and account for <0.1% of all malignant tumor of the breast, of which the conversi… Show more

“…Larger tumor size and positive resection margin are well known to be risk factors for local tumor recurrence. Recurrence tumor can be lower or the same grade as the initial one, but in majority of cases, tumors with a more aggressive growth and enhanced malignancy are found on recurrence [26,27,28]. In our study, a girl that had been operated for phylloid tumor had a recurrent tumor 10 months after thr initial surgery.…”

“…Contrary to the other two reported cases, our patient developed an aggressive transformation after multiple recurrences while in the case report by Gunasekaran et al, the patient developed fibrosarcoma in the very first recurrence after surgery. In the other case reported by Pant et al, the patient developed such change at the third recurrence [9,10].…”

“…It constitutes 0.3-1.0% of mammary tumors and 2-3% of fibroepithelial neoplasms of the breast. 1,2 It usually presents as a rapidly growing and clinically benign breast lump in females within fourth to fifth decade of life and rarely it occurs in adolescents and the elderly. 3 Grossly, the tumor displays characteristics of a large, malignant sarcoma.…”
