PURPOSE: Malignant phyllodes tumors (MPT) are exceptionally rare, and the genomic drivers of these tumors are still being elucidated. We performed comprehensive genomic profiling (CGP) of MPT to identify genomic alterations that will inform approaches to targeted therapy for patients with MPT, including relapsed, refractory, and metastatic disease. METHODS: DNA was extracted from formalin-fixed, paraffin-embedded samples from 24 consecutive patient cases of MPT...

We present the case of a 31-year-old woman with an inflammatory and ulcerative malignant phyllodes tumor in her right breast. A right modified radical mastectomy and transverse rectus abdominis myocutaneous (TRAM) flap were performed. A month after the initial operation, several masses recurred at the superior margin and deep margin of the TRAM flap. Wide excision was performed, but masses recurred at the inferior margin and in both lung fields 2 weeks after the second operation. Six weeks after the second operation, the patient died due to progression of dyspnea and respiratory failure...

INTRODUCTION: Phyllodes tumors (PTs) are rare fibroepithelial tumors of the breast which are classified as benign, borderline, or malignant. Malignant PTs account for <1% of malignant breast tumors, and borderline tumors have potential to progress to malignant tumors. Metastatic recurrences are most commonly documented in bone and lungs. We report an extremely rare presentation of recurrent malignant PTs involving the brain, lung, lymph nodes, and bone. CASE: A 66-year-old female presented with a large breast mass...

A 70-year-old woman noticed a mass in her right breast. Breast ultrasonography showed a low echo mass with a smooth border to the greatest dimension measuring 5.4 cm. Needle biopsy showed an increase in the number of spindle-shaped cells with diffuse fascicles having nuclei with seasonal polymorphisms in the stroma, which led to the final diagnosis of spindle cell sarcoma. Immunohistochemistry analysis showed a CAM5.2-negative, AE1/AE3 partly-positive, bcl-2-positive, ER-negative, PgR-negative, SMA-positive, S-100-negative, desmin-negative, CD34-negative, and keratin 5/6-negative tumor that was suspected to be a phyllodes tumor...

BACKGROUND: Phyllodes tumors of the breast are the rarest of all breast neoplasms. Giant phyllodes tumors (>10 cm) of the breast have been less discussed in the literature. Reconstruction of the large defect created after wide excision (safety margin >1 cm) is a challenge in these patients. We present one technique using a bi-pedicled deep inferior epigastric perforator flap for post-mastectomy breast reconstruction for giant phyllodes tumors. METHODS AND RESULTS: We treated three patients with giant phyllodes tumors between 2013 and 2016...

BACKGROUND: Tonsillar metastasis is very rare and accounts for only 0.8% of tonsillar tumors. And phyllodes tumor of the breast with tonsillar metastasis is very rare. CASE PRESENTATION: A 57-year-old Japanese woman received surgery (partial mastectomy) of malignant phyllodes tumor. Seven months after initial surgery, pharyngeal pain, swelling, and a feeling of dyspnea developed, and tumor was found in the left palatine tonsil. Computed tomography for further evaluation showed a tonsillar lesion with contrast enhancement, and tonsillar metastasis was suspected...

Primary breast sarcoma, arising from connective tissue within the breast, is extremely rare, accounting for less than 1% of all primary breast malignancies and no more than 5% of all sarcomas. The rarity of this pathology limits most studies to case reports and small retrospective studies, which has led to a lack of consensus on the clinical management. We report a clinical case of a 52-year-old woman, perimenopausal, previously healthy, with regular breast surveillance, who presented with a large (>20 cm) and rapidly expanding hypervascularized tumor of the left breast developed over 10 days, with a very thin preulcerative skin over the last 4 days...

Objective: To study the relationship between morphological characteristics, grading, diagnosis and prognosis in phyllodes tumors (PT) of the breast. Methods: A retrospective study was carried out on 83 PTs diagnosed between 1999 and 2003 that were classified semi-quantitatively according to the WHO recommendation. Follow-up data was available for some cases, and Cox regression analysis was used to evaluate factors affecting metastasis and recurrence. Results: All cases were classified into the benign (57.8%), borderline (28...

AIMS: Pulmonary adenofibromas are rare benign fibroepithelial tumours of the lung with unknown histogenesis and an indolent clinical behaviour. Their stroma resembles that of solitary fibrous tumours, while the glands are composed of respiratory epithelium organized in a phyllodes-like architecture. Differentiation of pulmonary adenofibromas from other more aggressive intrathoracic tumours is clinically relevant. However, their biology is unknown. Here, we sought to characterize pulmonary adenofibromas at a clinicopathologic level and to define whether they could be underpinned by a highly recurrent somatic genetic alteration akin to tumours with similar morphology...

Phyllodes tumors of the breast are rare tumor types that consist of 0.3-1.0% in all breast tumors. The naming and classification of breast phyllodes tumor have been debated for years. Based on the classification criteria modified by WHO in 2003, this review mainly introduced the clinicopathologic characteristics, pre-operational diagnosis and the treatment of breast phyllodes tumors, and also summarized the prognostic factors related to tumor recurrence.

BACKGROUND: Fibroepithelial lesions of the breast (FEL) are atypical lesions diagnosed on core-needle biopsy. The purpose of this study was to determine the rate at which FELs are upstaged to phyllodes tumor on excision, and to examine the clinical and radiological factors that may be predictive of upstaging. METHODS: A retrospective review from the medical records of patients diagnosed with FEL on CNB at a single institution between 2010 and 2015 was performed...

BACKGROUND: Metaplastic breast carcinoma (MBC) is a rare type of breast cancer and its diagnosis in routine practice can be challenging and may require immunohistochemical (IHC) characterisation if no conventional invasive or in situ carcinoma is present. Previous IHC studies of MBC often had a small sample size and did not investigate the different histological subtypes. This study aimed to assess the immunoprofile of MBC subtypes in a large series. METHODS: 172 MBC diagnosed in routine and referral practice in Nottingham over 26 years were reviewed by 3 breast pathologists...

AIMS: Previous concordance studies examining accuracy of breast diagnosis by pathologists, typically targeting difficult, histologically challenging breast lesions using artificial and restrictive environments, have reported aberrantly high levels of diagnostic discordance. The results of these studies may be misinterpreted by non-pathologists and raise concerns relating to routine practice. This study aims to assess the diagnostic agreement among UK breast pathologists. METHODS: Two hundred and forty consecutive breast lesions, submitted by participants from their routine practice, included in the UK National Health Service Breast Screening Programme (NHSBSP) breast pathology EQA scheme during the last 10 years were reviewed...

Benign phyllodes tumor (BPT) is a biphasic neoplasm composed of bland stromal and epithelial elements. Cytologic diagnostic criteria of BPT, though documented in the literature, diagnostic pitfalls in fine-needle aspiration cytology (FNAC) may occur due to sampling error, high cellularity, ductal hyperplasia, paucity of stromal component, and occasional dissociation of epithelial cells. Here, we describe a case of BPT diagnosed by histology in a 19-year-old female, where FNAC features were inconclusive due to paucity of stromal component, predominance of tubular adenoma-like epithelial component, and due to the presence of other overlapping features with fibroadenoma...

PURPOSE: Malignant phyllodes tumor of the breast (MPTB) accounts for less than 1% of whole breast neoplasm. Surgery is regarded as the primary treatment of choice in patients with MPTB, but the necessity of postoperative radiation therapy (RT) has been a subject of debate. Our aim was to evaluate effects of postoperative RT for MPTB using a large population database. METHODS: Using the Surveillance, Epidemiology, and End Results Program (SEER) database (1983-2013), clinico-pathologic prognostic factors were evaluated...
