Myofibroblast differentiation plays an important role in the malignant progression of phyllodes tumor (PT), a fast-growing neoplasm derived from periductal stromal cells of the breast. Macrophages are frequently found in close proximity with myofibroblasts, but it is uncertain whether they are involved in the myofibroblast differentiation during PT progression. Here we show that increased density of tumor associated macrophage (TAM) correlates with malignant progression of PT. We found that TAM stimulated myofibroblast differentiation and promoted the proliferation and invasion of PT cells...

BACKGROUND: We evaluated shear-wave elastography (SWE) and color Doppler ultrasonography (US) features for fibroepithelial lesions (FELs), and to evaluate their utility to differentiate fibroadenomas (FAs) and phyllodes tumors (PTs). METHODS: This retrospective study included 67 FELs pathologically confirmed (49 FAs, 18 PTs). B-mode US, SWE and color Doppler US were performed for each lesion. Mean elasticity (Emean), maximum elasticity (Emax), and vascularity were determined by SWE and Doppler US...

Phyllodes tumor is a rare fibroepithelial biphasic tumor of the breast composed of hypercellular mesenchymal stroma and double-layered epithelial component, arranged in clefts with leaf-like projections. Phyllodes tumor with coincidental presence of invasive carcinoma or in situ ductal carcinoma in the same or distinct breast is a rare occurrence, documented by some reports. Invasive carcinoma can be seen within or outside the phyllodes tumor. Skin ulceration by malignant phyllodes tumor with coexisting invasive carcinoma as collision tumor is extremely rare...

Fibroepithelial tumours are the most common type of solid breast tumours. They include the common fibroadenomas and the rare phyllodes tumours. Fibroadenomas usually present in younger patients and are smaller than phyllodes tumours. They are benign and do not require any treatment or follow-up. Further examination (usually ultrasound-guided thick-needle biopsy) is recommended if in doubt about the diagnosis. Phyllodes tumours can be divided into benign, borderline and malignant tumours and are primarily treated with surgery, breast-conserving surgery if possible...

Giant phyllodes tumors (PT) are an uncommon fibroepithelial neoplasm and especially rare in adolescent girls. Diagnosis is difficult not only due to the rarity of PT, but also owing to the resemblance of its clinical and imaging features with fibroadenoma. The author reports a case of a giant PT in a 14-year-old girl. Clinical examination showed a large painful mass in the left breast, and an abscess was initially suspected. But magnetic resonance imaging (MRI) displayed features characteristic of PT. Following complete surgical excision of the mass, histopathology confirmed the diagnosis of a benign PT with diffuse myxoid changes, consistent with the MRI findings...

Salinity, one of the major environmental constraints, threatens soil health and consequently agricultural productivity worldwide. Acacia auriculiformis, being a halophyte, offers diverse benefits against soil salinity; however, the defense mechanisms underlying salt-tolerant capacity in A. auriculiformis are still elusive. In this study, we aimed to elucidate mechanisms regulating the adaptability of the multi-purpose perennial species A. auriculiformis to salt stress. The growth, ion homeostasis, osmoprotection, tissue tolerance and Na(+) exclusion, and anatomical adjustments of A...

Clinically relevant histological categorization of fibroepithelial lesions can be a daunting task, especially in a core needle biopsy. Assessment of stromal nuclear atypia, including nuclear pleomorphism and mitotic activity, is a key morphological feature employed to classify fibroepithelial lesions. We describe a case of fibroadenoma with markedly atypical nuclear features in the stromal cells that led to misclassification as phyllodes tumor in the core needle biopsy. Excision showed a fibroadenoma containing pleomorphic stromal giant cells, with occasional mitotic figures, including atypical forms...

Phyllodes tumours (PTs) are rare fibroepithelial neoplasms representing about 0,2% to 2% of all breast tumors with an incidence of about 2.1 per million. The classification proposed by the World Health Organization for PTs into benign, borderline, and malignant is based on a combination of several histologic features. High-grade malignant phyllodes tumors may spread by hematogenous route. While smaller and moderate size malignant phyllodes may typically be seen, gigantic ones with larger than 10 cm in diameter are very rare...

A 28 year old woman has suffered over the previous month from a post-traumatic swelling sensation of the left breast. Ultrasonography demonstrates a 9 cm, sharply-cut, rounded, hypo-echogenic lesion. Surgery is performed, with the hypothesis of an haematoma. The pathological analysis of the lesion shows a malignant phyllodes tumour with heterologous rhabdomyosarcomatous features. No metastasis is found. A radical mastectomy is performed and the patient benefits from an adjuvant radio-chemotherapy. Phyllodes tumours represent up to 1 % of all mammary cancers, with 10-20 % of malignant lesions...

Phyllodes tumors of the breast are rare neoplasms that account for <1% of all mammary tumors and 2-3% of fibro-epithelial neoplasms of the breast. We evaluated the clinicopathological characteristics of a cohort of 246 Chinese patients in relation to the expression of epithelial-to-mesenchymal (EMT) markers in benign, borderline and malignant tumors and the prognostic value of different surgical regimens. We observed that survival outcomes correlated with the mode of surgical management in the three patient groups...

PURPOSE: This study aims to obtain the accurate time intensity curve (TIC) of a dynamic contrast-enhanced magnetic resonance image (DCE-MRI) by eliminating the normal tissue enhancement and obtaining pure lesion information. The TIC of DCE-MRI is sometimes distorted because of the influence of normal tissue. In this paper, a new tracer-kinetic modeling based on total variation (DC-TV) is proposed to address this problem by decomposing the DCE-MRI into the normal tissue image and the lesion image...

Malignant phyllodes tumors of the breast are a rare entity. They occur infrequently but most often in younger women in comparison to typical epithelial-based breast cancers. Treatment of these tumors is not without controversy and in this review we will present an update on the diagnosis and management of malignant phyllodes tumors of the breast.

Fibroepithelial lesions (FELs) are the most frequent breast tumors in adolescent females. The pubertal hormonal surge could impact the growth and microscopic appearance of FELs in this age group. In this study, we evaluate the morphology and clinical behavior of FELs in adolescents. We searched the 1992-2012 pathology data base for FELs in females 18 years old or younger (F ≤18 years). Seven FELs from 1975 to 1983 were also included. Three pathologists reviewed all available material. Patient (pt) characteristics and follow-up information were obtained from electronic medical records...

INTRODUCTION: Fibroepithelial tumours are a heterogeneous group of biphasic neoplasms consisting of a proliferation of both epithelial and stromal components. Fibroadenoma (FA) and Phyllodes Tumour (PT) constitute the major entities. It is crucial to distinguish benign from borderline PT (low grade malignant PT), because the former do not metastasize, have a lesser risk of local recurrence and initial local recurrences are histologically benign in almost all instances. Multiple Immunohistochemical (IHC) markers are being studied to find their utility in grading the PT accurately for planning proper treatment...
