Here, we describe a patient with bilateral breast cancer and melanoma, and with a concomitant double variant, namely p.Gln563Ter in BRCA1 and p.Lys3326Ter in BRCA2. The BRCA2 p.Lys3326Ter (K3326X) (rs11571833) mutation identified in our patient is a debated substitution of thymidine for adenine which is currently regarded as benign polymorphism in main gene databases. Recent studies, however, describe this variant as associated with breast and ovarian tumors. Based on the observation of the cancer's earliest age of onset in this subject, our purpose was to reevaluate this variant according to recent papers indicating a role of powerful modifier of the genetic penetrance...

A variety of molecular techniques can be used in order to unravel the molecular composition of cells. In particular, the microarray technology has been used to identify novel biomarkers that may be useful in the diagnosis, prognosis, or treatment of cancer. The microarray technology is ideal for biomarker discovery as it allows for the screening of a large number of molecules at once. In this review, we focus on microRNAs (miRNAs) which are key molecules in cells and regulate gene expression post-transcriptionally...

There has been tremendous progress in detection of breast cancer in postmenopausal women, resulting in two-thirds of women surviving more than 20 years after treatment. However, breast cancer remains the leading cause of cancer-related deaths in premenopausal women. Breast cancer is increasing in younger women due to changes in life-style as well as those at high risk as carriers of mutations in high-penetrance genes. Premenopausal women with breast cancer are more likely to be diagnosed with aggressive tumours and therefore have a lower survival rate...

BACKGROUND: We evaluated the diagnostic implications of a small-voxel reconstruction for lymph node characterization in breast cancer patients, using state-of-the-art FDG-PET/CT. We included 69 FDG-PET/CT scans from breast cancer patients. PET data were reconstructed using standard 4 × 4 × 4 mm3 and small 2 × 2 × 2 mm3 voxels. Two hundred thirty loco-regional lymph nodes were included, of which 209 nodes were visualised on PET/CT. All nodes were visually scored as benign or malignant, and SUVmax and TBratio(=SUVmax/SUVbackground) were measured...

Objectives: Controversy exists about the localization of non-palpable breast lesions. In many countries, the gold standard for the diagnosis of these lesions is needle localization due to its accuracy. This study sought to compare the ultrasound- and radio-guided occult lesion localization (ROLL) as a simple method with the conventional procedures in terms of their diagnostic power. Methods: This study was conducted on 94 patients with non-palpable breast lesions detected by ultrasonography and localized by the combination of ultrasonography and using radiopharmaceuticals...

BACKGROUND: Phyllodes tumors (PT) are uncommon biphasic tumors, accounting for less than 1% of all breast primary neoplasms. They form a wide variety of tumors ranging from benign to malignant. Several histological features are used to grade PT into 3 categories: benign (grade I), borderline (grade II) and malignant (grade III) tumors. The aim of our study was to analyse histolopathological, radiological and clinical features of PT from an experience of a single center. METHODS: It was a retrospective study including 106 patients diagnosed with phyllodes tumors on surgical specimens at the department of pathology, of Hassan II university hospital (Fez, Morocco), from 2009 to 2016...

Male breast disease is uncommon. Men presenting with breast symptoms may represent unique diagnostic challenges for the radiologist, particularly if imaging findings are not classic for gynecomastia or carcinoma. In this paper we review 10 unusual male breast cases, 5 benign and 5 malignant, including the radiologic findings, differential diagnosis, pathology and management.

RATIONALE AND OBJECTIVES: Gynecomastia is the benign enlargement of the male breast because of proliferation of the glandular component. To date, there is no radiological definition of gynecomastia and no quantitative evaluation of breast glandular tissues in the general male population. The aims of this study were to supply radiological-based measurements of breast glandular tissue in the general male population, to quantitatively assess the prevalence of gynecomastia according to age by decades, and to evaluate associations between gynecomastia and obesity, cirrhosis, and dialysis...

Premature thelarche is a benign condition that affects young girls and may be interpreted as a sign of central precocious puberty (CPP). Parental concern is common when breast development is noted in a young girl. It is important to differentiate premature thelarche from CPP, as the latter is a more serious disorder that may affect final adult height and menarcheal age, and may have psychological implications as well. Distinguishing between the two conditions clinically may help the patients avoid unnecessary testing...

PURPOSE: Chemical exchange saturation transfer (CEST) MRI for breast lesion characterization is promising. However, artifacts are prone to develop in breast CEST imaging as a result of strong lipid signals. The aims of the study are (i) to develop and validate the CEST-Dixon imaging sequence for simultaneous water-fat separation and B0 mapping; and (ii) use the CEST-Dixon method to characterize suspicious lesions in patients undergoing percutaneous biopsy. METHODS: The gradient-echo multi-echo Dixon acquisition is used to create fat-free CEST and B0 maps...

Juvenile papillomatosis of the breast represents a rare benign proliferative disorder that affects women younger than thirty years of age. Although it is a localized lesion, it does not have well-demarcated margins. These patients tend to have a strong family history for cancer. As it has similar clinical presentation with that of a fibroadenoma, it usually receives the diagnosis of the latter in the preoperative period. Nonetheless, it has distinct microscopic features such as ductal papillomatosis and cysts that are helpful in the diagnosis...

REVIEW
Ian S Fentiman
This review examines the symptoms, need for referral and management of the benign breast conditions which afflict males, together with the steps that are necessary to exclude or confirm male breast cancer. The most common complaint is gynaecomastia, either true or pseudo, and the majority of these cases need reassurance without over-investigation. Drugs that induce breast enlargement are described in order that, when possible, a medication switch can be made. Men receiving endocrine therapy for prostate cancer may develop painful gynaecomastia and this can be relieved with tamoxifen...
