Interrelations between cytokines, produced by invasive ductal carcinoma (IDC) and fibroadenoma (FA) of the breast, and angiogenic growth factor VEGF-A, expressed in IDC and FA, were investigated. The analysis of the cytokine profiles of IDC and FA was performed by cultivation of tumor biopsy specimens in vitro. Testing of the cytokine-producing reserve of the tumors for production of VEGF-A was conducted by culturing samples of IDC and FA in a medium containing polyclonal activator (a complex of phytohemagglutinin, concanavalin A, and lipopolysaccharide)...

INTRODUCTION: Polymastia and polythelia may be asymptomatic or cause pain, restriction of arm movement, milk discharge, cosmetic problems or anxiety. Cosmesis is the main indication for surgical excision of accessory breasts in axilla. In addition it also confirms the diagnosis and allays the patient's fear of harbouring a malignancy. AIM: To evaluate the presentation of symptoms, investigations required for diagnosis and the management to improve the treatment protocols in patients with breast diseases...

Fibroadenoma is the most common benign breast tumor in women of reproductive age, carrying little to no risk of breast cancer development. We report on a case of a woman with history of neuroendocrine tumor who on follow-up imaging tests underwent whole-body PET/CT study using Ga DOTATATE. The scan showed increased focal activity in the right breast, which was biopsied revealing a fibroadenoma. The presented data suggests cell surface overexpression of somatostatin receptors by this benign breast tumor. Moreover, this finding emphasizes the need for cautious interpretation of Ga DOTATATE-avid breast lesions that could mimic malignancy in neuroendocrine tumor patients...

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a pathology that is usually diagnosed by accident during pathological examination of other breast lesions. PASH is an uncommon and benign tumoral lesion of the mammary stroma that can be pathologically mistaken for other tumours, such as phyllodes, fibroadenoma, and sometimes even angiosarcoma. We report the case of a 45-year-old woman with complaints of huge bilateral breast enlargement. This is a rare case of PASH presenting with gigantomastia and involving bilateral breasts and axillae simultaneously...

Up to 19% of breast malignancies may be missed by conventional imaging techniques, especially when they are concurrent or co-located with other benign lesions. However, more sensitive techniques, such as magnetic resonance imaging (MRI), are often too expensive for routine use in developing countries. Contrast-enhanced, dual-energy digital mammography (CESM) is a recently introduced imaging modality whose performance has been reported to be similar to that of MRI. Being much cheaper, CESM may constitute a good alternative for improving diagnostic sensitivity in these countries...

Cytokine production was evaluated in supernatants of cultured tumor cells that were obtained by biopsy of the breast invasive ductal carcinoma (IDC) and breast fibroadenoma (FA) and grown in vitro. In the IDC supernatants, the concentrations of pro-inflammatory (pro-oncogenic) cytokines IL-17, IL-18, and IFNγ and of IL-1 receptor antagonist were significantly higher than in the FA cell supernatants. The concentrations of anti-inflammatory cytokine IL-10 and MCP-1 protein in supernatants of IDC cells were significantly lower than those determined in FA supernatants...

A palpable breast mass is one of the most common presenting features of breast carcinoma. However, the clinical features are frequently nonspecific. Imaging performed before biopsy is helpful in characterizing the nature of the mass. For women with clinically detected breast masses, the vast majority will require evaluation with ultrasound. Diagnostic mammography is the initial imaging modality of choice for women aged ≥ 40 years; ultrasound is typically necessary unless a definitively benign mass is identified as the etiology of the clinical finding...

Aims Pseudoangiomatous stromal hyperplasia (PASH) diagnosed on core needle biopsy is generally excised. As a consequence, PASH as an incidental finding, may lead to unnecessary excisions. This study categorized PASH in biopsies as diffuse versus focal to determine if this correlates with the presence of a mass. Methods In a 10-year period, 253 biopsies were identified and 159 met inclusion criteria. Of these, 47 biopsies had excisions. Biopsies and excisions were classified as diffuse, involving 2 adjacent lobules, or focal PASH in a single lobule or noncontiguous lobules...

Modifications of microvascular configuration are essential features encountered during the progression of breast tumors. Our objectives were to correlate morphometrically evaluated microvessel parameters (microvessel density [MVD], microvessel caliber [VC], microvessel cross-sectional area [VCSA], percentage of total VCSA [%TVCSA], and total microvessel boundary density [TVBD]) with histologic grades of invasive ductal carcinoma (IDC) of the breast and benign breast lesions. Sixty cases of IDC presented with modified radical mastectomy, and 20 benign breast fibroadenomas were evaluated for various microvessel parameters, using CD34-immunostained histologic sections by computerized image morphometry...

Exome sequencing has recently identified highly recurrent MED12 somatic mutations in fibroadenomas (FAs) and phyllodes tumors (PTs). In the present study, based on a large series, we confirmed the presence of MED12 exon 1 and 2 mutations in 49% (41/83) of PTs, 70% (7/10) of FAs and 9.1% (1/11) of fibromatoses. We show that MED12 mutations are associated with benign behavior of phyllodes tumors, as they are detected less frequently in malignant PTs (27.6%) compared to benign (58.3%) and borderline (63.3%) PTs, respectively (p = 0...

A 45-year-old woman with a differentiated thyroid carcinoma received adjuvant radioiodine therapy following total thyroidectomy and left modified radical neck dissection. A posttherapy planar radioiodine scan showed multifocal uptake in the thyroid bed and left chest. SPECT/CT revealed a fibroadenoma in the left breast. Six months later, an I scan showed no iodine avidity in the breast fibroadenoma, whereas ultrasonography showed no significant change in the size of the fibroadenoma. Altered radioiodine uptake of a breast fibroadenoma can be observed on follow-up scans after cytotoxic radioiodide treatment in patients with differentiated thyroid carcinoma...

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...

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...

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...
