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...

Background Phyllodes tumor (PT) of the breast is an uncommon fibroepithelial neoplasm. Malignant epithelial transformation in PT is rare. This study reports clinicopathologic characteristics and outcomes of patients with malignant epithelial transformation in PT. Methods From an institutional database of 183 patients with newly diagnosed PT referred to a Canadian provincial cancer institution between 1999 and 2014, 11 cases of PT with concomitant in situ or invasive carcinoma were identified. Descriptive analysis was performed to document the characteristics, treatment and outcomes of this cohort...

Phyllodes tumor of the breast is an uncommonly encountered disease. The tumor presenting as fungating breast mass or 'ruptured' breast is an even more rare presentation of an unusual disease. This report documents the case of a 60-year-old female with delayed presentation of a large exophytic mass of the left breast. Biopsy of this lesion was non-diagnostic, so excision via left total mastectomy was performed. The final pathology was consistent with malignant phyllodes tumor. This report highlights the features of a rare breast cancer, the challenges in obtaining a definitive diagnosis, and the treatment of this disease, in an effort to provide clinicians with an example of the management of such a peculiar entity...

INTRODUCTION: Malignant phyllodes tumor of the breast is an extremely rare entity usually presenting with similar clinical features with those of benign fibroadenoma. Due to its scarcity and clinical presentation, it is quite difficult for clinicians to suspect and diagnose the disease at its early stage. There is currently no consensus regarding adjunctive radiotherapy, hormonal therapy and systemic chemotherapy recommended for malignant phyllodes tumors. PRESENTATION OF CASE: This report presents a case of early-stage malignant phyllodes tumor treated by lumpectomy only without adjunctive chemoradiation therapy, but with an excellent outcome...

RATIONALE: Phyllodes tumor is a rare fibro epithelial neoplasm of the breast. They resemble fibroadenomas clinically and can be mistakenly ignored sometimes. PATIENT CONCERNS: We report the case of a young woman with her first presentation to hospital due to a hypoglycemia and she underwent 2 excised fibroadenomas in the same breast before diagnosed of malignant phyllodes tumor. She was complaining about 2 masses presented in her right breast 4 months after mastectomy...

OBJECTIVE: To investigate whether the parameters derived from intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) could differentiate phyllodes tumors (PTs) from fibroadenomas (FAs) by comparing the apparent diffusion coefficient (ADC) values. METHODS: This retrospective study included seven FAs, 10 benign PTs (BPTs), four borderline PTs, and one malignant PT. Biexponential analyses of IVIM were performed using a 3 T MRI scanner. Quantitative IVIM parameters (pure diffusion coefficient [D], perfusion-related diffusion coefficient [D*], and fraction [f]) were calculated...

Phyllodes tumors account for less than 1% of tumors of the mammary gland, have both epithelial and stromal components and are classified as benign, borderline and malignant. The malignant tumors are highly heterogeneous: they can differentiate to liposarcomas, fibrosarcomas, rhabdomyosarcomas, chondrosarcomas or osteosarcomas. The differentiation to osteosarcoma is extremely rare, constitutes 1.3% of cases and is very aggressive. The standard treatment of these tumors is surgical. The role of radiotherapy and chemotherapy is not clear...

Phyllodes tumor is a relatively uncommon fibroepithelial neoplasm of the breast characterized by proliferation of both stromal and epithelial elements. Benign phyllodes tumors are distinguished from fibroadenomas by their prominent leaf-like architecture and exaggerated intracanalicular stromal growth pattern. Typically, these lesions affect older natal females; however, we present what we believe is the first reported case of benign phyllodes tumor in a hormonally treated transgender woman.

Malignant phyllodes tumors (MPT) are rare breast neoplasms. Preoperative diagnosis is often challenging due to the unspecific clinical, radiological, and histological characteristics of the tumor. Dissemination pathways are local with chest wall invasion, regional with lymph nodes metastasis, and distant, hematogenous, mostly to the lungs, bones, and brain. Distant metastasis (DM) can be synchronous or appear months to years after the diagnosis and initial management. The current report describes the case of a 57-year-old woman presenting with a giant/neglected MPT of the breast, with no DM at initial staging, treated by radical modified mastectomy...

PURPOSE: Phyllodes tumors (PTs) of the breast are rare, accounting for less than 1% of all breast tumors. Among PTs, malignant PTs (MPTs) have malignant characteristics and distant metastases occur in about 20% to 30% of MPTs. However, there is no effective treatment for MPTs with distant metastasis, resulting in an abject prognosis. We performed targeted deep sequencing on PTs to identify the associations between genetic alterations and clinical prognosis. METHODS: We performed targeted deep sequencing to evaluate the genetic characteristics of PTs and analyzed the relationships between clinical and genetic characteristics...

INTRODUCTION: Phyllodes tumors (PTs) of the breast are extremely rare accounting for less than 1% of all breast tumors globally. Case records at the Trinidad and Tobago Cancer Registry show that only 0.003% of the reported breast cancer cases between 1995 and 2009 were PTs. PRESENTATION OF THE CASE: We report a 45-year-old woman who presented with swelling of the left breast. Ultrasound, mammogram and computed tomography imaging confirmed the presence of a mass in the right upper inner quadrant of the left breast...

BACKGROUND: Fibroadenoma is overwhelmingly the most common pediatric breast lesion. Breast malignancy is quite uncommon in children, most frequently metastatic or hematological malignancy. Core biopsy has largely replaced excision for diagnosis of breast masses in adults. OBJECTIVE: The purpose of this study is two-fold: (1) compare utilization at our institution of interventional procedures vs. surgery for breast mass diagnosis in patients ≤18 years and (2) propose guidelines for breast imaging and biopsy in this population...

Breast fibroepithelial lesions (fibroadenomas and phyllodes tumors) are underpinned by recurrent MED12 exon 2 mutations, which are more common in fibroadenomas and benign phyllodes tumors. TERT promoter hotspot mutations have been documented in phyllodes tumors, and found to be more frequent in borderline and malignant lesions. Several lines of evidence suggest that a subset of phyllodes tumors might arise from fibroadenomas. Here we sought to investigate the genetic differences between phyllodes tumors with fibroadenoma-like areas vs...

A 50-year-old woman with a large right breast mass was emergently hospitalized for generalized weakness and fatigue. A histological examination of tumor biopsy specimens revealed a phyllodes tumor (PT). She suddenly lost consciousness due to severe hypoglycemia. Non-islet cell tumor hypoglycemia (NICTH) due to the PT was suspected. The tumor was emergently resected. A histological examination revealed a borderline PT. The patient recovered from the hypoglycemic episode. High-molecular-weight insulin-like growth factor II was detected in serum that had been collected preoperatively and in the tumor tissue, but not in serum that had been collected postoperatively...
