In humans, phyllodes tumors of the breast are rare fibroepithelial tumors that are further characterized as benign, borderline, or malignant according to their histomorphologic features. Phyllodes tumors are poorly responsive to treatment other than excision. NHP have a much lower frequency of mammary neoplasia than do humans, and none of the lesions reported previously in NHP are consistent with phyllodes tumors. Here we present the case of a mammary tumor in a northern greater galago (Otolemur garnettii) that was histologically characteristic of a malignant phyllodes tumor...

BACKGROUND Contrast enhanced spectral mammography (CESM) is a new method of breast cancer diagnosis in which an iodinated contrast agent is injected and dual-energy mammography is obtained in multiple views of the breasts. The aim of this study was to compare the degree of enhancement on CESM with lesion characteristics on mammography (MG) and lesion histology in women with suspicious breast lesions. MATERIAL AND METHODS The degree of enhancement on CESM (absent, weak, medium, or strong) was compared to lesion characteristics on MG (mass, mass with microcalcifications, or microcalcifications alone) and histology (infiltrating carcinoma, intraductal carcinoma, or benign) to compare sensitivity of the two modalities and to establish correlations that might improve diagnostic accuracy...

We evaluated the clinical significance of indoleamine 2,3-dioxygenase(IDO)in intra-cystic tumors of the breast. IDO activitycan be measured byusing the tryptophan(Trp)/kynurenine(Kyn)ratio. Trp and Kyn were measured by high performance liquid chromatography(HPLC). We took liquid from 3 intra-cystic papilloma cases and 5 intra-cystic breast cancer cases. Then, we measured the Trp/Kyn ratio in these samples, and we evaluated the difference in the Trp/Kyn ratio between the papilloma group and the breast cancer group...

Juvenile giant fibroadenoma is a very rare breast disease affecting young girls of premenarche and adolescent ages. It is a benign fibroepithelial tumour characterised by stromal and epithelial proliferation that causes rapidly growing breast mass. Bilateral symmetrical involvement is extremely rare. In this article, we describe this entity in a girl aged 13 years who presented with bilateral gigantically enlarged breasts. Ultrasonography and MRI showed large, multilobulated masses involving both breasts entirely...

Acquired resistance to doxorubicin in breast cancer is a serious therapeutic problem. In this study, we investigated whether Pseudomonas aeruginosa mannose-sensitive hemagglutinin (PA-MSHA) could inhibit the growth of doxorubicin-resistant breast cancer cells. We found that the expressions of Nrf2 and p62 in breast cancer were higher than that in the corresponding adjacent normal tissues and benign breast epithelial cell. The expressions of Nrf2 and p62 in breast cancer doxorubicin-resistant cells MCF-7/ADR were higher than that in doxorubicin-sensitive cells MCF-7...

BACKGROUND: A sarcoid reaction is a phenomenon characterized by histologically proven granulomatous lesions without evidence of sarcoidosis. This pathology is a benign tumor itself, but several reports have described sarcoid reactions accompanying malignant tumors. Sarcoid reactions occur in various cancers, such as skin, lung, ovary, stomach, and breast cancers. However, only a few published reports have described sarcoid reactions in patients with colorectal cancer. CASE PRESENTATION: A 76-year-old woman underwent laparoscopic sigmoidectomy for sigmoid colon cancer...

Carcinoma ex pleomorphic adenoma (CEPA) is a carcinoma that shows histologic evidence of arising in or from a benign pleomorphic adenoma. Carcinoma ex pleomorphic adenoma often occurs in parotid glands, but is extremely rarely in the tongue. A 53-year-old Japanese woman was referred to the Department of Oral and Maxillofacial Surgery, Nagasaki University Hospital, because of tumor of the right dorsum tongue. She had a history of surgery of breast cancer (invasive ductal carcinoma) and it was disseminated to the lung and bone...

Solitary fibrous tumor (SFT) is an uncommon neoplasm of mesenchymal origin, which can be benign or malignant. Most SFTs develop from the pleura, but they can also be found in other sites. There are only few reports of SFT occurring in the breast. We herein report such a rare case. Sonography demonstrated an ovoid lesion mimicking a fibroadenoma, whereas color Doppler imaging showed marked internal vascularity. A brief literature review on imaging features of SFTs is added. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound, 2016...

High risk human papilloma viruses (HPVs) may have a causal role in some breast cancers. Case-control studies, conducted in many different countries, consistently indicate that HPVs are more frequently present in breast cancers as compared to benign breast and normal breast controls (odds ratio 4.02). The assessment of causality of HPVs in breast cancer is difficult because (i) the HPV viral load is extremely low, (ii) HPV infections are common but HPV associated breast cancers are uncommon, and (iii) HPV infections may precede the development of breast and other cancers by years or even decades...

We report a case of a 36-year-old woman that presented with a painful mass in the outer quadrants of the left breast that had grown rapidly. Physical examination revealed a well circumscribed elastic mass and breast ultrasound showed a cyst measuring 26 mm with vegetation growing on the inner wall. Microscopic evaluation, after fine needle aspiration cytology (FNAC), suggested benign lesion. Tumorectomy was performed and the final diagnosis was a pure squamous cell carcinoma (SCC) of the breast. A simple mastectomy with sentinel node biopsy was performed...

Phyllodes tumors of the breast are rare, accounting for less than 1% of the breast tumors. They are mostly seen in women between 45 and 49 years old. These are fast growing tumors with a large spectrum of behavior (from benign to metastatic) and can resemble fibroadenomas. Correct diagnosis mostly through core needle biopsy is important to decide whether a surgical excision has to be done. Here we report a case of a 57-year-old woman with a fast growing, ulcerated tumor in the left breast. Core needle biopsy suggested a malignant phyllodes tumor with heterologous liposarcomatous differentiation...

In this systematic review and meta-analysis, we report measured elasticities of benign and malignant breast pathologies from shear wave elastography (SWE), quantitatively confirm the effect of the selected region of interest (ROI) on these measures and test the hypothesis that a metric of heterogeneity based on the mean and maximum elasticity can improve specificity of diagnosis. The elasticities of benign, malignant and specific pathologic states are reported from 22 publications encompassing 2989 patients, identified from a structured search of the literature from May to September 2015...
