Phyllodes tumor

Andrea D Olivas, Jerome Taxy, Rebecca Wolsky, Tatjana Antic
Phyllodes tumor of the prostate is a rare mesenchymal tumor conventionally regarded as a stromal tumor of undetermined malignant potential. While the initial presentation is that of urinary obstruction and/or hematuria, the subsequent clinical behavior is thought to be a function of stromal cellularity and cytologic changes of malignancy. Of histologic interest, the epithelial component of this tumor varies, including intestinal metaplasia, as seen in the present case.

PURPOSE: Prostate cancer (PC) patients who undergo antiandrogen monotherapy are offered prophylactic radiation therapy (PRT) to the breast buds to avoid gynecomastia. The aim of the present study was to evaluate whether the risk of breast cancer (BC) in men with PC as their first cancer diagnosis was influenced by PRT. METHODS AND MATERIALS: From the Norwegian Cancer Registry, we collected data from all patients with PC as their first cancer diagnosis from 1997 to 2014...

Phyllodes tumor (PT) of the breast is a rare but clinically important fibroepithelial tumor with potential risks of recurrence and metastasis. Recent studies identified recurrent TERT promoter mutations in PTs. However, the clinical significance of this alteration has not been fully examined. Two hundred and seven PTs from two intuitions were included. All cases were subjected to immunohistochemical analysis for TERT expression. Analysis of TERT promoter mutations was further performed by Sanger sequencing targeting the hotspot mutation region on cases from one of the involved institutions...

Malignant phyllodes tumor is a rare tumor of the breast occurring in females usually between the ages of 35 and 55 years. It is often difficult to distinguish benign from malignant phyllodes tumors from other benign entities such as fibroadenomas. This case presentation demonstrates a woman with malignant phyllodes tumor treated with mastectomy with abdominal skin flap reconstruction.

INTRODUCTION: Benign Osseous metaplasia of the breast is rare, with only a few cases reported in the literature. Here we present a case of benign osseous metaplasia of the breast presenting as a breast lump. CASE PRESENTATION: 38-year-old previously well woman presented with a one-year history of bilateral breast pain and a left-sided breast lump. Ultrasound and mammography suggested calcified fibroadenoma. An ultrasound-guided true cut biopsy revealed fibrous tissue containing foci of adenosis in the presence of a myoepithelial cell layer...

The aim of this study was to explore the independent prognostic factors related to postoperative recurrence-free survival (RFS) in patients with breast phyllodes tumors (PTBs). A retrospective analysis was conducted in Fudan University Shanghai Cancer Center. According to histological type, patients with benign PTBs were classified as a low-risk group, while borderline and malignant PTBs were classified as a high-risk group. The Cox regression model was adopted to identify factors affecting postoperative RFS in the two groups, and a nomogram was generated to predict recurrence-free survival at 1, 3, and 5 years...

BACKGROUND: Breast carcinoma arising in a benign fibroepithelial tumor is rare, and is usually discovered incidentally during examination of the breast mass. METHODS: We evaluated the clinicopathological features, treatment, and prognosis of seven women with breast carcinomas within benign fibroepithelial tumors, diagnosed and treated at a single institution between 2011 and 2015. RESULTS: Seven women, aged 21-64 years, visited our hospital complaining of a breast mass detected by self-checking or screening examination...

Mammary fibroepithelial lesions encompass a wide spectrum of tumors ranging from an indolent fibroadenoma to potentially fatal malignant phyllodes tumor. The criteria used for their classification based on morphological assessment are often challenging to apply and there is no consensus as to what constitutes an adequate resection margin. We studied a retrospective cohort of 213 fibroepithelial lesions in 178 patients (80 fibroadenomas with unusual features and 133 phyllodes tumors: 63 benign, 41 borderline, and 29 malignant) in order to describe the spectrum of changes within each group, with special emphasis on margin evaluation...

Fibroepithelial breast lesions encompass a heterogeneous group of neoplasms that range from benign to malignant, each exhibiting differing degrees of stromal proliferation in relation to the epithelial compartment. Fibroadenomas are common benign neoplasms that may be treated conservatively. Phyllodes tumors are relatively rare lesions, and classified as benign, borderline, or malignant based on histologic evaluation of various parameters. The diagnostic interpretation of "gray-zone" fibroepithelial lesions often imposes formidable demands on a pathologist's skills...

A 72-year-old woman noted a mass in the left breast about 5 years ago, but she did not consult a medical institution. She was taken in the ambulance and hospitalized to our department due to severe anemia and malnutrition. A computed tomography( CT)scan indicated an 18×12 cm tumor in her left breast. A fiborsarcoma protuberance was suspected based on needle core biopsy results. Simple mastectomy was performed to control hemorrhage and infection. The resected tumor weighed 2.6 kg. The pathological diagnosis was a malignant phyllodes tumor...

Atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) and its higher-grade counterpart, dedifferentiated liposarcoma (DDL), are extraordinarily rare tumors in the breast. The main differential diagnostic consideration of primary breast ALT/WDL is malignant phyllodes tumor with liposarcomatous differentiation, and the main differential diagnostic consideration of DDL in the breast is metaplastic breast carcinoma, particularly the spindle cell type, with heterologous sarcomatous differentiation...

A 76-year-old female patient with a malignant phyllodes tumor underwent modified radical mastectomy and wide excision. Multiple nodules were observed in the operated wound area. Positron emission tomography-computed tomography (PET-CT) revealed recurrent disease in the left breast, the adjacent left third rib, the left internal mammary region and the left ilium. A novel formulation of bevacizumab (5 mg/m2, first day) in combination with liposomal doxorubicin (Lipodox, 30 mg/m2, second day) was administered for 3 cycles every 2 weeks, and subsequently wide excision was performed...

BACKGROUND: Phyllodes tumors (PT) are uncommon biphasic tumors, accounting for less than 1% of all breast primary neoplasms. They form a wide variety of tumors ranging from benign to malignant. Several histological features are used to grade PT into 3 categories: benign (grade I), borderline (grade II) and malignant (grade III) tumors. The aim of our study was to analyse histolopathological, radiological and clinical features of PT from an experience of a single center. METHODS: It was a retrospective study including 106 patients diagnosed with phyllodes tumors on surgical specimens at the department of pathology, of Hassan II university hospital (Fez, Morocco), from 2009 to 2016...
