The pathological feature of intraductal papillomas is defined as a papillary structure composed of a fibrovascular stromal core lined by luminal epithelial cells and myoepithelial cells. We used droplet digital PCR for the mutational analysis of AKT1 (E17K) and PIK3CA (H1047R, E542K, and E545K) in 60 papillomas. AKT1 and PIK3CA mutations were detected in 12 (20%) and 17 (28%) of the papillomas, respectively. In five tumors harboring mutations, mutational analysis of AKT1 or PIK3CA was performed separately using luminal epithelial cells and myoepithelial cells sorted using anti-CK19 antibody and anti-SMA antibody...

BACKGROUND: Our aim was to compare the pathologic upgrade rates of high-risk breast lesions (HRLs) on digital two-dimensional mammography (DM) vs digital breast tomosynthesis (DBT). STUDY DESIGN: The study cohort was composed of patients with HRLs diagnosed by image-guided core needle biopsy from December 2007 to February 2011 (DM group, before DBT integration) and from January 2013 to March 2016 (DBT group, after complete DBT integration). Medical records were reviewed for surgical outcomes and follow-up imaging...

Background: Although the risk factors for breast cancer are well established, namely female gender, early menarche and late menopause plus the protective influence of early pregnancy, the underlying causes of breast cancer remain unknown. The development of substantial recent evidence indicates that a handful of viruses may have a role in breast cancer. These viruses are mouse mammary tumor virus (MMTV), bovine leukemia virus (BLV), human papilloma viruses (HPVs), and Epstein-Barr virus (EBV-also known as human herpes virus type 4)...

We investigated the usefulness of vacuum-assisted biopsy(VAB)using the EnCor ENSPIRE®system for initial biopsy of breast tumors. We analyzed 24 cases of VAB using the EnCor ENSPIRE®system performed for breast tumors. Of 24 mammary lesions, 12 cases(50.0%)were diagnosed as malignant. Among them, 7 cases(29.2%)were invasive ductal carcinoma(IDC) and 5 cases(20.8%)were ductal carcinoma in situ(DCIS). Six cases required tumor resection for definitive diagnosis; 1 case was diagnosed with IDC, 2 cases with DCIS, 2 cases with intraductal papilloma(IDP), and 1 case with atypical ductal hyperplasia( ADH)...

The aim of this prospective study was to identify characteristics of breast lesions on contrast enhanced ultrasound (CEUS) that can be a source of diagnostic ambiguity and cause under- or overestimation of examined breast lesions. 215 women (range 23-76 y., mean age 53.16 y) with 215 breast lesions were examined by B-mode ultrasound, followed by CEUS and core biopsy. CEUS parameters: degree of opacification, character of washout and preliminary CEUS result (suspicious, non-suspicious, uncertain) were subsequently correlated with histopathological outcomes...

Nipple discharge is a common symptom in clinical practice, representing the third leading breast complaint, after pain and lumps. It is usually limited and has a benign etiology. The risk of malignancy is higher when the discharge is uniductal, unilateral, spontaneous, persistent, bloody, or serous, as well as when it is accompanied by a breast mass. The most common causes of pathologic nipple discharge are papilloma and ductal ectasia. However, there is a 5% risk of malignancy, mainly ductal carcinoma in situ...

Intraductal papilloma falls under the category of benign breast mass. However, recent studies show that it can harbor occult carcinoma. The management of benign intraductal papilloma remains controversial because of its nonspecific radiologic and histological findings, as well as its association with surrounding malignant pathology. The purpose of this study is to investigate upgrade rates of a benign intraductal papilloma on surgical excision and the need for surgical excision of papillary lesions diagnosed at core needle biopsy...

PURPOSE: In this study, we demonstrate a novel imaging technique, based on ultra-small-angle X-ray scattering (USAXS) that uses a Laue-case Si wafer as the angle analyzer. METHODS: We utilized the (1 1 1) diffraction plane of a 356 μm thick, symmetrically cut Si wafer as the angle analyzer, denoted by A[L]. With this device, we performed USAXS imaging experiments using 19.8 keV synchrotron X-rays. The objects we imaged were formalin-fixed, paraffin-embedded breast tumors (an invasive carcinoma and an intraductal papilloma)...

BACKGROUND: Multiple oncogenic viruses including, mouse mammary tumor virus, bovine leukemia virus, human papilloma virus, and Epstein Barr virus, have been identified as separate infectious pathogens in human breast cancer. Here we demonstrate that these four viruses may be present in normal and benign breast tissues 1 to 11 years before the development of same virus breast cancer in the same patients. METHODS: We combined the data we developed during investigations of the individual four oncogenic viruses and breast cancer...

OBJECTIVE: To determine the feasibility and safety of breast endoscopic thulium laser ablation for treatment of intraductal neoplasia. STUDY DESIGN: Ductoscopy is a minimally invasive endoscopic approach of the milk ducts of the breast via the nipple. Besides diagnosis in women with pathologic nipple discharge (PND), it allows non-invasive removal of intraductal lesions with a stalk like papillomas. Removal, however, is often incomplete and flat lesions cannot be targeted...

AIM: HPV DNA has never been investigated in nipple discharges (ND) and serum-derived extracellular vesicles, although its presence has been reported in ductal lavage fluids and blood specimens. MATERIALS & METHODS: We analyzed 50 ND, 22 serum-derived extracellular vesicles as well as 51 pathologic breast tissues for the presence of 16 HPV DNA types. RESULTS: We show that the presence of HPV DNA in the ND is predictive of HPV DNA-positive breast lesions and that HPV DNA is more represented in intraductal papillomas...

BACKGROUND: Previous studies in our laboratory showed that Daucus carota oil extract (DCOE) possesses remarkable in-vitro anticancer activity and antitumour promoting effect against DMBA/TPA skin carcinogenesis in mice. Chemical analysis of DCOE led to the isolation of the β-2-himachalen-6-ol (HC), major sesquiterpene with a potent anticancer activity against various colon, breast, brain and skin cancer cells. This study investigated the anticancer activity of HC against invasive epidermal squamous cell carcinoma cells and evaluated its effect in a DMBA/TPA skin carcinogenesis Balb/c murine model...

Phyllodes tumor of the breast is a rare neoplasm, particularly in young women. It is usually presented as a unilateral palpable mass and nipple discharge presented as a symptom is rare. We reported a 22-year-old Taiwanese woman in our hospital for right breast tumor with nipple discharge. Preoperative diagnosis was intraductal papilloma but the histological examination showed a malignant phyllodes tumor with intraductal growth. Symptom of nipple discharge and intraductal growth in phyllodes tumor are rare presentations...

Papillary lesions of the breast range from benign to atypical to malignant. Although papillomas without frank cancer are benign, their management remains controversial. When a core needle biopsy of a lesion yields a diagnosis of intraductal papilloma with atypia, excision is generally recommended to rule out a concurrent malignant neoplasm. For intraductal papillomas without atypia, however, recommendations for excision versus observation are variable. The aims of this study are to evaluate the rate of concurrent malignancies for intraductal papilloma diagnosed on core needle biopsy and to assess the long-term risk of developing cancer after the diagnosis of a papillary lesion...
