Traditionally, phyllodes tumors are graded by the use of a set of histologic data into benign, borderline, and malignant

Local recurrence of phyllodes tumor (PT) of the breast is an adverse outcome that can result in sarcomatous degeneration. The aim of this study was to investigate the histologic and surgical factors associated with local recurrence We reviewed the FNA findings of 18 histologically proven phyllodes tumours and 18 fibroadenomas, checking in each case the epithelial features, the stromal features, and any atypia. Using a semi-quantitative score assessed by two observers we were able in most cases to distinguish a phyllodes tumour from a fibroadenoma Visual survey of surgical pathology with 11131 high-quality images of benign and malignant neoplasms & related entities.

A phyllodes tumor is a very rare breast tumor that develops from the cells in the stroma (connective tissue) of the breast. Other names for these tumors include phylloides tumor and cystosarcoma phyllodes. These tumors are usually benign, but they can come back and cause the breast to look abnormal if not totally removed Among the 24 cases labeled as phyllodes tumor on cytology, 17 were benign phyllodes, 03 borderline phyllodes and 3 were malignant. All the three malignant phyllodes had been diagnosed as malignant on cytology. One benign phyllodes tumor was discordant on histopathology and was reported as a fibroadenoma. The two discordant cases were reviewed

The final pathology revealed 173 fibroadenomas and 40 phyllodes tumors. The data, including patient characteristics, clinical presentation, and mammography, ultrasonography (US), and pathology findings were analyzed Phyllodes Tumors of the Breast. Phyllodes tumors (FILL-odes or full-OH-deez) can also be spelled phylloides tumors (full-OY-deez). These are rare breast tumors that start in the connective (stromal) tissue of the breast. Phyllodes tumors are most common in women in their 40s, but women of any age can have them INTRODUCTION Phyllodes tumors are uncommon fibroepithelial breast tumors that are capable of a diverse range of biologic behaviors. In their least aggressive form, phyllodes tumors behave like benign fibroadenomas, although with a propensity to recur locally following excision without wide margins

[Phyllodes tumor: histology and behavior]

Introduction. Phyllodes tumor is a very rare tumor of the breast, incidence being between 0.3% and 0.9% of all breast tumors. 1 They are most commonly found in women aged between 40 and 50 years. 2 The World Health Organization (WHO) has published guidelines classifying this tumor into benign, borderline or malignant according to the histological features such as stromal cellularity, stromal. Malignant phyllodes is the least common type of fibroepithelial lesion and they develop 2-5 years later than their benign counterparts. With classic histological changes of leaf-like architecture, malignant phyllodes can be diagnosed on a biopsy Cellular fibroepithelial lesions (CFELs) are a heterogeneous group of tumors encompassing cellular fibroadenoma (CFA) and phyllodes tumor (PT). Distinction between the two is challenging on core needle biopsy (CNB) specimens. The objective of this study was to evaluate histologic features that can help distinguish PT from CFA on CNB specimens Phyllodes Tumor Benign phyllodes tumor is characterized by the presence of leaf-like growth pattern and elongated epithelial-lined clefts. Stromal cellularity is most dense in areas adjacent to the epithelial components. Increased mitotic figures may be present in this zone Phyllodes Tumor : Low-grade. This low-grade phyllodes tumor arose in a 55 y/o female who presented with a steadily enlarging nodule in her left breast. At low magnification, the histologic features are highly suggestive of the diagnosis

Most patients are young with median age of 37 - 39 years at presentation. Good prognosis if no myometrial invasion, bland histology and no sarcomatous overgrowth ( Oncol Rep 1998;5. MATERIALS AND METHODS: Data were analysed on 183 patients with newly diagnosed phyllodes tumors from 1999 to 2014. Five-year Kaplan-Meier local recurrence and survival were compared between cohorts with benign (n=83), borderline (n=50) and malignant phyllodes tumor (n=49) histology. RESULTS: Median (range) follow-up was 65 (0.5-197) months Phyllodes Tumor of the Breast. Classification / Lists . Biphasic lesions of the breast. Adenomyoepitheliom Surgery is the main treatment for phyllodes tumors of the breast. This is the case regardless of whether they are benign or malignant. Because these tumors can come back if enough normal tissue is not removed, surgery should involve removing the tumor and at least 1 cm of the surrounding tissue. Some doctors feel that an even wider margin of healthy tissue should be removed (wide excision) The vast majority of metastatic tumors have malignant histology, although a very small percentage of patients with benign phyllodes tumors subsequently develop distant metastases. 45 Approximately 20% of patients with malignant phyllodes tumors develop metastases, and they are treated with similar systemic agents as those with soft tissue.

Purpose: To retrospectively evaluate the magnetic resonance (MR) imaging findings of phyllodes tumor of the breast and to compare these findings with the histologic grade. Materials and Methods: Institutional review board approval and informed consent were obtained. The authors reviewed the MR findings in 30 female patients aged 16-73 years (mean, 40.2 years) with surgically confirmed. In patients with phyllodes tumors, all three methods individually have low sensitivity and, even in combination, the diagnostic accuracy is often poor because mammary phyllodes tumors rarely develop and their clinical, imaging and cytology and histology findings are similar to those of fibroadenomatous breast tumor, which has a high incidence.

A phyllodes tumor is a rare tumor of the breast. Phyllodes tumors grow in the connective tissue of the breast, called the stroma. This includes the tissue and ligaments that surround the ducts. Phyllodes tumors are a fibroepithelial tumor composed of an epithelial and a cellular stromal component. They may be considered benign, borderline, or malignant depending on histologic features including stromal cellularity, infiltration at the tumor's edge, and mitotic activity. All forms of phyllodes tumors are regarded as having malignant. Phyllodes tumors contain different kinds of cells, but the cancerous part is a sarcoma, or cancer of connective tissue. These tumor cells are very different than ductal breast cancer cells, and behave differently. Phyllodes Tumor Staging and Treatment

Malignant phyllodes tumor (PT) is one of the rare breast tumors that is difficult to diagnose. First reported in 1838, PT of the breast accounts for less than 1% of all breast masses. Based on histological features, PT is categorized on a spectrum of benign to malignant tumors The role of the pathologist in the preoperative diagnosis of phyllodes tumours of the breast is critical to appropriate surgical planning. However, reliable differentiation of phyllodes tumour from cellular fibroadenoma remains difficult. Preoperative diagnostic accuracy allows correct surgical treatment, avoiding the pitfalls of reoperation because of inadequate excision, or surgical. Tumors rarely involve the nipple-areola complex or ulcerate to the skin. Patients with metastases may present with such symptoms as dyspnea, fatigue, and bone pain. A firm, mobile, well-circumscribed, nontender breast mass is appreciated.
