Abstract

Background: Phyllodes tumors (cystosarcoma phyllodes) are uncommon lesions in the female breast. Rarely, the occurrence of carcinoma within a phyllodes tumor has been reported in the literature, but has never been associated with lymph node metastases.

In Situ and Invasive Ductal Carcinoma Within a Borderline Phyllodes Tumor

“…The stroma is benign in the majority of the cases [2, 6]. The patients' age ranged from 26 to 80 years, with most of them in the 5 th or 6 th decades, similarly to our patient.…”

“…The epithelial component of phyllodes tumors may show various types of changes like apocrine and squamous metaplasia, adenosis and less commonly proliferative changes [5]. However, carcinoma arising within a phyllodes tumor is rare with less than 30 cases reported in the literature [6]. Most of these cases are of lobular type [7].…”

“…The prognosis of carcinoma in phyllodes tumor is generally favourable because the stroma is benign in the majority of the cases and cancer detection often occurs early [9]. Lymph node metastases associated with a carcinoma within a phyllodes tumor are extremely rare [2, 6, 7]. Treatment must be performed according to the carcinomatous component independently of the phyllodes tumor [6].…”

Ductal Carcinoma in Situ within a Benign Phyllodes Tumor of Breast: Report of a Case

“…Parfitt et al reported a 26-year-old woman presented with a left breast mass and palpable lymph nodes in the left axilla. The pathologic study showed extensive high grade DCIS and invasive carcinoma of no special type, entirely located within the phyllodes tumor that subsequent axillary lymph node dissection revealed metastatic carcinoma (11).…”
