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...

Erythema annulare centrifugum (EAC) is a clinical reaction pattern that includes lupus erythematosus, spongiotic dermatitis (particularly pityriasis rosea), pseudolymphoma and cutaneous B-cell lymphoma. However, it can be the result of cutaneous metastasis by an internal carcinoma. We present the case of a 38-year-old woman with bilateral inflammatory breast cancer following multimodal therapy. After chemotherapy, the patient developed EAC on her back, clinically suspect of subacute cutaneous lupus erythematosus...

The ErbB/B2 (HER-2/neu) oncogene family plays a critical role in the development and metastatic spread of several tumor types including breast, ovarian and gastric cancer. In breast cancer, HER-2/neu is expressed in early disease development in a large percentage of DCIS lesions and its expression is associated with an increased risk of invasion and recurrence. Targeting HER-2 with antibodies such as trastuzumab or pertuzumab has improved survival, but patients with more extensive disease may develop resistance to therapy...

Phyllodes tumor is a rare breast tumor described by Müller (1938) as a lesion comprising leaflike stromal fibrous components and narrow cysts. The frequency of distant metastasis from this entity is reportedly approximately 20%, and no effective therapy has been established, so the prognosis is poor. This report describes the case of a 60-year-old woman with a history of left lung resection who showed metastasis of a mammary gland malignant phyllodes tumor to the oral cavity. Intraoral examination showed an elastic, hard mass measuring 28 × 27 mm in the gingiva around the left mandibular second molar...

Mammary analog secretory carcinoma (MASC) is a recently described tumor of the salivary glands named for its morphological and molecular similarity to secretory carcinoma of the breast. Many primary carcinomas arising from the adnexal glands also share similar morphology to those arising from the breast. Brandt et al first described primary cutaneous MASC in 2009 and since then only 2 other cases have been reported. Herein, we describe a long-standing mass on the arm of an otherwise healthy 40-year-old female...

The skeleton represents a common site of metastases for osteotropic cancers such as prostate and breast tumors and novel therapeutic targets and new markers for the monitoring of bone lesions are urgently needed. The formation of bone metastases is a complex process that starts at the level of the confined tumor and that is characterized by a dynamic crosstalk between the primary cancer and the future metastatic site, the bone. Factors released by the primary tumor contribute to prepare a fertile "soil", where a "pre-metastatic niche" is established prior to future colonization by cancer cells...

Metastatic tumors are rare in the breast. Well-differentiated neuroendocrine tumors (WDNETs) are slow-growing neoplasms that arise from neuroendocrine cells, particularly in the gastrointestinal tract and bronchial tree. Metastatic WDNET to the breast is a rare entity. We present a case report of ileal WDNET metastatic to the breast which was initially identified as a small mass in the patient's left breast on screening mammography. Targeted ultrasound identified a suspicious mass, and ultrasound-guided percutaneous core biopsy was performed...

Abnormal uterine bleeding in a patient on maintenance hormonal therapy for breast cancer should raise concern for endometrial abnormalities including rare uterine metastasis from the breast. Hormonal receptor profile changes in metastatic lesions favoring human epidermal growth factor receptor 2 (HER2) overexpression may be involved in the pathogenesis of metastasis to the uterus.

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...

Locallyadvanced breast cancer lesions often compromise the patient's qualityof life(QOL). Mohs paste is a histopathological fixative containing zinc chloride as the main ingredient. It has been applied to perform chemosurgeryon skin tumors. In recent years, this paste has reportedlybeen veryeffective for controlling various symptoms of skin metastases in inoperable advanced cancer, such as pungent odor and hemorrhage, in the field of palliative care. We evaluated the clinical significance of immunosuppressive acidic protein(IAP)and C-reactive protein(CRP)in the serum of patients with locallyadvanced breast cancer duringMohs paste treatment...

We evaluated the clinical significance of indoleamine 2,3-dioxygenase(IDO)during fulvestrant therapyfor multiple metastatic breast cancer patients. IDO activitycan be measured using the tryptophan(Trp)/kynurenine(Kyn)ratio. Trp and Kyn were measured using high-performance liquid chromatography(HPLC). The serum Trp/Kyn level in patients with multiple metastatic breast cancer was lower than in patients without metastases. IDO activityincreased after breast cancer metastases developed. IDO activitywas correlated with the number of metastatic lesions during toremifene and fulvestrant therapy...

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...

INTRODUCTION: The use of texture indices (TI) to characterize tumor heterogeneity from Positron Emission Tomography (PET) images is increasingly investigated in retrospective studies. Yet, the interpretation of PET-derived TI values has not been thoroughly reported. Furthermore, the calculation of TI lacks a standardized methodology, making it difficult to compare published results. To allow for TI value interpretation, we investigated the changes in value of six TI computed from simulated and real patient data...

Tumor heterogeneity has been shown for several cancers including breast cancer (BC). Despite the fact that expression of tumor markers may change throughout the metastatic process, rebiopsies at the time of recurrence are still not performed routinely at all institutions. The aims of the study were to evaluate changes in biomarker profiles during the metastatic process and to investigate whether previous anthracycline or endocrine therapy given in the adjuvant setting could affect the biomarker profile in metastatic lesions...
