  • Cystic hypersecretory carcinoma of the breast is a rare variant of ductal carcinoma of breast, first described in 1984 by Rosen and Scott. Histologically, it is characterized by the formation of dilated ducts and cysts containing an eosinophilic secretory product resembling thyroid colloid. Cytologic findings show a few clusters of atypical ductal epithelial cells in amorphous proteinaceous material with clacking artifact. Differential diagnosis include mucinous carcinoma and benign mucocele-like tumor. We present two cases of fine needle aspiration cytology of cystic hypersecretory intraductal carcinoma of the breast with a review of the literature.

  • Tumors that metastasize to the pituitary gland are unusual, and are typically seen in elderly patients with diffuse malignant disease. The most common metastases to the pituitary are from primary breast and lung cancers. We report a 65-year-old woman with pituitary metastasis from breast cancer who presented with recent-onset left progressive deterioration of visual acuity and visual field. The clinical diagnosis was made after brain and sellar magnetic resonance imaging showed a large sellar mass compressing the optic chiasm and invading the pituitary stalk. An otorhinolaryngology and neurosurgery team removed the tumor via a transsphenoidal approach, and this procedure obtained symptomatic relief. Postoperatively, metastasis from breast invasive ductal adenocarcinoma was confirmed histologically. We report this unusual case with a review of the relevant literature.

  • Metastatic tumors to the jawbones are an infrequent but not rare phenomenon. The most common site of distant primary tumor metastasis to the jaw bones is the breast. The clinical signs and symptoms, and radiographic appearance of these lesions can be quite variable. In this report, an invasive ductal carcinoma of the breast that metastasized to the whole mandible is presented. The patient's medical history revealed that she had undergone a modified radical mastectomy on the right breast eight years ago.

  • Direct injection of foreign material, such as liquid paraffin and silicone, into the breast can induce a foreign body granulomatous reaction and fibrosis, resulting in hard, nodular breast masses and architectural distortion that can mimic neoplasm. Conventional methods, including physical examination, mammography, and ultrasonography are of little use to differentiate between foreign body-induced mastopathy and breast cancer. In patients with foreign body injection such as breast augmentation, dynamic contrast enhanced MR imaging is an excellent imaging modality. Here, the authors report the MR imaging and pathological findings of ductal carcinoma in situ (DCIS) with multicystic changes in a 41-year-old woman with a previous history of interstitial mammoplasty by paraffin injection.

  • Overexpression of human epidermal growth factor receptor 2 (HER2) is found in about 20% of breast cancer patients. With treatment using trastuzumab, an anti-HER2 monoclonal antibody, systemic control is improved. Nonetheless, the incidence of brain metastasis does not be improved, rather seems to be increased in HER2-positive breast cancer. The mainstay treatment for brain metastases is radiotherapy. According to the number of metastatic lesions and performance status of patients, radiosurgery or whole brain radiotherapy can be performed. The concurrent use of a radiosensitizer further improves intracranial control. Due to its large molecular weight, trastuzumab has a limited ability to cross the blood-brain barrier. However, small tyrosine kinase inhibitors such as lapatinib, has been noted to be a promising agent that can be used as a radiosensitizer to affect HER2-positive breast cancer. This review will outline general management of brain metastases and will focus on preclinical findings regarding the radiosensitizing effect of small molecule HER2 targeting agents.

  • Cellular stress severely disrupts endoplasmic reticulum (ER) function, leading to the abnormal accumulation of unfolded or misfolded proteins in the ER and subsequent development of endoplasmic reticulum stress (ERS). To accommodate the occurrence of ERS, cells have evolved a highly conserved, selfprotecting signal transduction pathway called the unfolded protein response. Notably, ERS signaling is involved in the development of a variety of diseases and is closely related to tumor development, particularly in breast cancer. This review discusses recent research regarding associations between ERS and tumor metastasis. The information presented here will help researchers elucidate the precise mechanisms underlying ERS-mediated tumor metastasis and provide new directions for tumor therapies.

  • Hematologic malignancy of the breast is very rare. Here, we report a case of relapsed acute myeloid leukemia (AML) presenting as multiple breast masses. A 77-year-old female visited an outpatient clinic reporting palpable masses in both breasts. She had a medical history of AML, which showed complete remission after nine cycles of chemotherapy. On mammography and ultrasonography, there were multiple masses correlated with her palpable symptoms accompanied by enlarged lymph nodes. Core needle biopsy immunohistochemistry (IHC) results indicated AML and blastic plasmacytoid dendritic cell neoplasm. AML was confirmed using bone marrow biopsy. Although very rare, when a patient with a history of hematologic malignancy presents a palpable mass in the breast, clinicians should conduct proper tissue analysis, including IHC stating for leukemic markers, to guide appropriate diagnosis and treatment.

  • Purpose: The purpose is to explore the illness experience of Korean women with breast cancer using feminist phenomenology. Methods: Data were collected by individual in-depth interviews from ten women with total mastectomy. The data were analyzed using Colaizzi's method from feminist perspective to reveal implicit socio-cultural norms that oppress women with breast cancer. Results: Two categories and seven major themes emerged: cancer-related experience (1) unfairness of having breast cancer; (2) being confined to the gaze of the others; patriarchy-related experience (3) hardness of being daughter-in-law; (4) struggling to keep on being good mother; (5) continued housework as duty; (6) recognizing self as precious wife, and (7) awakening of true self. All participants felt it was very unfair to get breast cancer because they had done their best for roles of mother, wife, and daughter-in-law. They struggled to free themselves from the social disgrace like the roles imposed by the patriarchal society. By awakening their true selves, they could manage a balance between other-oriented life and self-oriented life. Conclusion: Oncology nurses need to provide psychosocial support for women with breast cancer in finding their true selves in a traditional patriarchal society where women are oppressed and breast cancer is stigmatized.

  • Background: The protective effect of metformin against breast cancer is inconclusive. Objective: To evaluate the effect of metformin on breast cancer risk and mortality in patients with type 2 diabetes. Method: A comprehensive literature search was performed for pertinent articles published prior to June 30, 2014, using PubMed and EMBASE. Study heterogeneity was estimated with $I^2$ statistic. The data from the included studies were pooled and weighted by random-effects model. The quality of each included study was assessed on the basis of the 9-star Newcastle-Ottawa Scale and publication bias was evaluated by visual inspection of a funnel plot. Results: Ten studies were included in the meta-analysis of the association of metformin and breast cancer risk. By synthesizing the data from the studies, the pooled odds ratio (OR) was 0.72 (95% CI: 0.59, 0.87) (p = 0.0005). Three cohort studies were included for meta-analysis of the association between metformin and breast cancer-related mortality. Metformin was associated with a significant decrease in mortality (Risk ratio: 0.68; 95% CI: 0.51, 0.90, p = 0.007). Conclusion: The present meta-analysis suggests that metformin appears to be associated with a lower risk of breast cancer incidence and mortality in patients with type 2 diabetes.

  • Herein, we report a case of synchronous bilateral triple negative invasive ductal breast carcinoma in a patient with discrepant pathologic response to neoadjuvant chemotherapy. Right and left breast cancer stages at the initial diagnosis were T1cN0M0 and T4dN3aM0, respectively. The patient was identified as a BRCA1 mutation carrier and treated with four cycles of adriamycin and cyclophosphamide, followed by four cycles of docetaxel. Bilateral breast cancer stages decreased with the first regimen. However, the bilateral breast cancers showed discrepant responses to chemotherapy with docetaxel. The right breast cancer showed a continuous tumor volume reduction while the left breast cancer showed marked progression. Finally, the tumor size was 0.3 cm and 12 cm in the right and left mastectomy specimens, respectively. As bilateral breast cancers of the same subtype may show discrepant responses to neoadjuvant chemotherapy, close monitoring and follow-up imaging are required to avoid delayed surgery.
