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...

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: 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...

Prostate cancer is a leading cause of death by cancer in male worldwide. Indeed, advanced and metastatic disease characterized by androgen resistance and often associated with neuroendocrine (NE) differentiation remains incurable. Using the spontaneous prostate cancer TRAMP model, we have shown that mast cells (MCs) support in vivo the growth of prostate adenocarcinoma, whereas their genetic or pharmacologic targeting favours prostate NE cancer arousal. Aiming at simultaneously targeting prostate NE tumor cells and MCs, both expressing the cKit tyrosine kinase receptor, we have tested the therapeutic effect of Imatinib in TRAMP mice...

Secreted protein acidic and rich in cysteine (SPARC) plays an essential role in tumor invasion and metastasis. The present work was undertaken to detect expression of SPARC mRNA in phyllodes tumors (PTs) and its association with SPARC protein expression. This study also evaluated expression of SPARC mRNA and its correlation between grade and clinical behavior of PTs. In addition, we assessed in PTs the association of expression of SPARC with that of matrix metalloproteinase (MMP)-2 and of MMP-9. SPARC mRNA expression was determined by RNAscope in situ hybridization (ISH) in 50 benign, 22 borderline, and 10 malignant PTs using a tissue microarray...
