“…Although the median age of occurrence of disease is 40-50 years, and the documented literature about ductal carcinoma in situ arising in phyllodes tumor is a rare situation especially in older patients, our case illustrates that this situation can be seen in younger ages. Moreover, our case presented here is the youngest patient with ductal carcinoma in situ arising in phyllodes tumor according to documented in the literature (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19).…”

“…Even this transformation is rare, most of them are infiltrative ductal carcinomas (2). Documented literature about ductal carcinoma in situ arising in phyllodes tumor is a rare situation (7)(8)(9)(10)(11)(12)(13)(14)(15)(16). We report a 19-year old patient who was diagnosed with ductal carcinoma in situ arising in a benign phyllodes tumor of the breast.…”

In Situ Ductal Carcinoma Arising in Benign Phyllodes Tumor in 19-Year Old Patient: A Case Report

et al. 2014

Phyllodes tumors are fibroepithelial lesions and malign forms are rare neoplasms with lower than 1% of all primary breast tumors. Malign forms are usually behaves like sarcomas because they occur in the stroma of the breast. Also proliferation of epithelium occurs and even it is less often, the epithelial component of phyllodes tumors can transform into malignancy too. This epithelial malignancies are usually in the form of infiltrative carcinomas and non-invasive tumors arising in benign phyllodes tumors are much rarer but can be seen. Literature include very few cases about this situation and cases are usually old woman. We report a 19-year old patient who was diagnosed with ductal carcinoma in situ arising in benign phyllodes tumor of the breast.

“…They are histologically unique in that they are composed of epithelial and stromal components (17). Phyllodes tumor of the breast is classified as benign, borderline, or malignant subtypes based on features of the tumor such as necrosis, margins (pushing or infiltrative), cellular atypia, stromal overgrowth, and number of mitoses per high power field (8,18). Malignancy is determined by characteristics of the stroma, and approximately 30% of phyllodes tumors are diagnosed as malignant.…”

“…These types of phyllodes tumors are classified as borderline in the literature (8,18). Based on examples in the literature, we performed a wide local excision to the 100-mm long round-shaped mass in the left breast (19).…”

Five-Year Disease-Free Follow-Up of a Borderline Breast Phyllodes Tumor in a 15-year-old Patient

2015

Phyllodes tumors are large breast tumors representing only 1% of breast neoplasms and are rarely seen in young women. Histologically, phyllodes tumors are classified as benign, borderline, or malignant based on the characteristics of the stroma. Although wide local excision is recommended for the treatment modality, the reoccurrence rate after surgical excision varies between 36% and 65%, with recurrence more likely in those with the tumor at the margins of excision. Our aim was to report -a case in a 15-year-old girl with a 115-mm borderline phyllodes tumor in her left breast mimicking a juvenile fibroadenoma. We presented a 5-year disease-free follow-up after wide local excision with negative margins.

“…The vascular stroma might have played a role in the quick recurrence and malignant transformation of the epithelial and mesenchymal components. In situ carcinoma has been reported before in association with phyllodes tumor, and most have been in situ lobular carcinomas (32)(33)(34). Positive E-cadherin expression in our case, which had histologically equivocal features, confirmed the presence of ductal carcinoma in situ (35,36).…”

Aggressive Giant Fibroepithelial Lesion with Unusual Vascular Stroma—A Case Report

2003

View full text Add to dashboard Cite

The stroma of fibroadenoma and phyllodes tumor usually consists of fibroblastic proliferation. Rarely the stroma contains bundles of smooth muscle. Pseudoangiomatous hyperplasia of the mammary stroma has been described in fibroadenomas. However, true benign vascular stroma has not been reported. We report a case of a 34-year-old Chinese woman who presented with a large mass occupying the entire left breast. Left mastectomy was performed and showed a large, well-circumscribed, lobulated, rubbery-firm tumor measuring 13 ؋ 10 ؋ 6 cm. A 34-year-old Chinese woman presented with a large mass occupying the entire left breast. Left mastectomy was performed that showed a remarkable fibroepithelial lesion with stroma showing extensive vascular proliferation. The patient developed a local recurrence a year later, and the resection was diagnosed as malignant phyllodes tumor with ductal carcinoma in situ. The patient had had right mastectomy 5 years ago in China before coming to Canada. No information on the pathology could be obtained.
