Papillary breast lesions are a heterogeneous group of tumors which mainly arise in the central mammary region, ranging from benign to malignant. Among them, solid papillary carcinoma (SPC) represents a very uncommon variant with indolent clinical behavior and excellent prognosis. The categorization of papillary lesions as benign, atypical or malignant is often difficult even for experienced pathologists. Furthermore, for prognostic purposes, to decide whether to consider a lesions as in situ when it is not associated with frank invasive foci of carcinoma may be problematic...

Disparities in cancer control exist in low- and middle-income countries (LMICs). Many countries do not have cancer registries to record incidence, mortality and prevalence and are reliant on Globocan estimates of their cancer burden. Poorer cancer control within and between countries occurs in those living remotely from urban centres, those in a low socioeconomic group and some ethnic groups who have lifestyle and belief systems which impact on cancer control. High-income countries generally have population screening programmes for cervix, breast and bowel cancer...

Ganoderma lucidum total triterpenes were evaluated for its apoptosis-inducing and anti-cancer activities. Cytotoxicity and pro-apoptotic effect of total triterpenes were evaluated in human breast adenocarcinoma (MCF-7) cell line using MTT assay and DNA fragmentation analysis. Total triterpenes induced apoptosis in MCF-7 cells by down-regulating the levels of cyclin D1, Bcl-2, Bcl-xL and also by up-regulating the levels of Bax and caspase-9. Anti-carcinogenicity of total triterpenes was analysed using dimethyl benz [a] anthracene (DMBA) induced skin papilloma and mammary adenocarcinoma in Swiss albino mice and Wistar rats respectively...

To evaluate whether biopsy with vacuum-assisted biopsy (VAB) devices improves histologic underestimation rates of benign papillomas when compared to smaller bore core needle biopsy (CNB) devices. Patients with biopsy-proven benign papillomas with surgical resection or minimum 12 months follow-up were selected. Two breast pathologists reviewed all pathology slides of percutaneous and excisional biopsy specimens. Histologic underestimation rates for lesions biopsied with 10-12 Gauge (G) VAB were compared to those with 14G CNB...

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...

James Sutherland Lawson, Wendy K Glenn, Noel James Whitaker
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...

AIMS: Hidradenoma papilliferum (HP) is a benign vulvar neoplasm that arises from anogenital mammary-like glands, and its morphology is similar to mammary intraductal papilloma. The aim of this study was to investigate oncogenic mutations involved in the tumourigenesis of HP. We focused specifically on PIK3CA and AKT1 mutations, which are both reported to be detected in 33% of mammary intraductal papillomas. METHODS: In total, seven HP cases were analysed. Clinicopathological analyses and immunohistochemistry for oestrogen receptor, p63, smooth muscle actin (SMA), p53 and β-catenin were performed...

BACKGROUND: Ductal carcinoma in situ of the male breast is an unusual lesion and most often associated with invasive carcinoma. On rare occasions when the in situ component is present in pure form, histological grade is almost always low to intermediate. Imaging for these patients is difficult as gynecomastia is often present and can mask underlying calcifications or carcinoma. CASE REPORT: We report a case of pure high-grade ductal carcinoma in situ of the male breast in a patient with clear nipple discharge...

Cowden syndrome (CS) is an uncommon autosomal dominant multiorgan/system genodermatosis. It is characterized by the development of multiple hamartomas of endodermal, mesodermal and ectodermal origin, an increased lifetime risk of breast, thyroid, endometrial and other cancers and an identifiable germline mutation. Mucocutaneous hamartomas are the most common lesions seen and mainly include facial trichilemmomas, oral mucosal papillomas and benign acral keratoses. Herein, we report a case of a 63-year-old Caucasian male with a long-established diagnosis of CS and history of thyroid cancer, colonic polyps, and innumerable trichilemmomas, seborrheic keratoses, squamous papillomas and non-melanoma skin cancers excised in the past...

Honokiol (C18H18O2) is a biphenolic natural product isolated from the bark and leaves of Magnolia plant spp. During the last decade or more, honokiol has been extensively studied for its beneficial effect against several diseases. Investigations have demonstrated that honokiol possesses anti-carcinogenic, anti-inflammatory, anti-oxidative, anti-angiogenic as well as inhibitory effect on malignant transformation of papillomas to carcinomas in vitro and in vivo animal models without any appreciable toxicity. Honokiol affects multiple signaling pathways, molecular and cellular targets including nuclear factor-κB (NF-κB), STAT3, epidermal growth factor receptor (EGFR), cell survival signaling, cell cycle, cyclooxygenase and other inflammatory mediators, etc...

Malignant papillary neoplasms of the breast comprise a number of microscopically distinct lesions, where apocrine metaplasia is commonly found in papillomas compared to other papillary lesions including papillary carcinomas. However, association of apocrine metaplasia in papilloma with Ductal Carcinoma in Situ (DCIS) is not very well defined. The lesions with apocrine metaplasia are not only difficult to categories, but also there is controversy regarding their relative risk of subsequent carcinoma development...
