INTRODUCTION: Pancreatic metastases are uncommon and only found in a minority of patients with widespread metastatic disease at autopsy. The most common primary cancer site resulting in pancreatic metastases is the kidney, followed by colorectal cancer, melanoma, breast cancer, lung carcinoma and sarcoma. PRESENTATION OF CASE: Herein, we report a 63-year-old male patient who presented -3.5 years after radical nephrectomy performed for renal cell carcinoma (RCC)-with a well-defined lobular, round mass at the body of the pancreas demonstrated by abdominal Magnetic Resonance Imaging (MRI)...

Breast cancer can be divided into four molecular subtypes with different prognoses using immunohistochemical markers in the routine clinicopathological work-up. The protein Ki-67 is of central importance in this context, in particular to distinguish between luminal A and luminal B carcinomas. Determination of the Ki-67 index of a carcinoma also allows a prediction of the likelihood of the response to chemotherapy. Additionally, the expression of certain cytokeratins in tumor cells is associated with a poor response to chemotherapy...

The diagnosis of a tumor-to-tumor metastasis in the central nervous system most commonly involves metastasis to a meningioma. These combined lesions are often radiographically unsuspected and mimic a meningioma. Most commonly, the source of metastatic disease are carcinomas from the lung and breast. To our knowledge, fewer than a half dozen cases of metastatic prostatic adenocarcinoma to a meningioma have been documented in the literature. This report documents a 67-year-old man who presented with worsening confusion and altered mental status, accompanied by symptoms of increased urinary frequency, incontinence, and difficulty urinating...

A wide range of health benefits have been ascribed to soya intake including a lowered risk of osteoporosis, heart disease, breast cancer, and menopausal symptoms. Because it is a hormonally active diet, however, soya can also be endocrine disrupting, suggesting that intake has the potential to cause adverse health effects in certain circumstances, particularly when exposure occurs during development. Consequently, the question of whether or not soya phyto-oestrogens are beneficial or harmful to human health is neither straightforward nor universally applicable to all groups...

The differential diagnosis of epithelial proliferative disease using core needle biopsy (CNB) is problematic because it is difficult to differentiate between intraductal papilloma, ductal hyperplasia, ductal carcinoma in situ, and invasive ductal carcinoma. Many studies have reported that breast cancer lesions are positive for neuroendocrine (NE) markers, whereas only a small number of studies have reported immunopositivity for NE markers in normal mammary tissues or benign lesions. We asked whether NE factors could be used as markers of breast cancer...

A 57-year-old woman presented to our department with a 2-month history of pain and paresthesia on the left side of the face 12 years after having undergone surgery for breast cancer. We performed an endoscopic biopsy and diagnosed metastatic breast cancer to the pterygopalatine fossa. There has been no recurrence for two years since the metastatic tumor was treated by radiation therapy. A literature search shows only one case of metastatic breast cancer with severe trigeminal neuralgia located in the V2 division of the trigeminal nerve area...

INTRODUCTION: Despite remarkable advances in tumor treatment, many patients still die from common tumors (breast, prostate, lung, CNS, colon, and pancreas), and thus, new approaches are needed. Many of these tumors synthesize bombesin (Bn)-related peptides and over-express their receptors (BnRs), hence functioning as autocrine-growth-factors. Recent studies support the conclusion that Bn-peptides/BnRs are well-positioned for numerous novel antitumor treatments, including interrupting autocrine-growth and the use of over-expressed receptors for imaging and targeting cytotoxic-compounds, either by direct-coupling or combined with nanoparticle-technology...

We report a case of interval breast cancer that was an invasive ductal carcinoma of the breast with neuroendocrine differentiation. The patient was a 66-year-old woman who had a breast lump. She had received breast cancer screening every other year. The last screening was 1 year and 6 months prior to diagnosis. A core needle biopsy for breast tumor led to a diagnosis of invasive ductal carcinoma. Breast conserving surgery plus sentinel lymph node biopsy was performed. The pathological diagnosis from the resected surgical specimen was invasive ductal carcinoma with neuroendocrine differentiation, positive for ER and PgR, and negative for HER2/neu protein expression...

Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant neoplasm, but, generally, asymptomatic with respect to pituitary involvement. The most common primary sites are breast in women and lung in men. We present the case of a 64-year-old patient with clinical visual changes, polyuria, polydipsia, and decreased level of consciousness whose tests showed pan-hypopituitarism, hypernatremia and low urine specific gravity, and extensive mass in sellar region...

UNLABELLED: : Neuroendocrine carcinoma of the breast is considered a rare entity, and for this reason there are no data from prospective clinical trials on its optimal management. Early stage tumors are usually treated with the same strategy used for the other types of invasive breast cancer. Anthracycline- and taxane-based regimens represent the most frequently administered chemotherapy in neoadjuvant and adjuvant setting, as well as for metastatic disease, although combinations of platinum compounds and etoposide have been widely used, in particular for small-cell histology and tumors with a high proliferation index...

Doublecortin-like kinase 1 (DCLK1), a microtubule associated kinase, has recently been proposed to be a putative marker for stemness and adverse prognosis in gastrointestinal cancers. However, it is not clear whether the protein also plays similar roles in breast cancer. Here, the expression of DCLK1 was analyzed in a large cohort of invasive breast cancers (IBC) by immunohistochemistry. DCKL1 was associated with favorable clinico-pathologic features, namely lower histologic grade, absence of lymphovascular invasion, fibrotic focus, necrosis and lower pN stage (p≤0...

UNLABELLED: Primary neuroendocrine cancer of the breast (NECB) is an extremely rare tumor. In 2003, the World Health Organization (WHO) recognized this category with three well-described subtypes: small cell, large cell, and carcinoid-like carcinoma; very few peer-review publications based on the WHO definition were encountered in the literature, and we conducted a literature search to investigate the reported incidence, diagnosis, prognosis, hormone receptor status, and treatment options for this rare tumor...

Metastases to the breast are uncommon, accounting for 0.5% of breast tumors, and most of them are originated from lymphoma, melanoma and carcinomas of various organs. Alveolar soft part sarcoma (ASPS) is a very rare neoplasm that is usually found in the lower extremities. Lungs are the common site of dissemination and may represent initial manifestation of disease. We report a clinically unsuspected case of ASPS presenting as a breast metastasis in a 25-year-old woman. The patient's medical history was notable for a thyroid cancer treated by surgery and radioiodine ablation 2 years ago...

The authors reported an uncommon presentation of metastatic neuroendocrine carcinoma to the breast detected by Tc-99m-HYNIC-TOC SPECT/CT in a 49 years old woman who, previously, had carcinoid tumor of left main bronchus and invasive ductal carcinoma of the right breast. Later, the patient developed left breast mass. Core needle biopsy of the mass revealed poorly differentiated invasive ductal carcinoma. The disease remained stable for 12 years without any treatment on that left breast (due to patient's rejection)...

BACKGROUND AND AIMS: The lung large-cell neuroendocrine carcinoma (LCNEC) is a very rare aggressive neuroendocrine tumor with a high propensity to metastasize and very poor prognosis. We report an atypical presentation of lung LCNEC was diagnosed from a metastatic nodule on the breast. METHODS: Our patient is a 59-years-old woman that presented in March 2014 nonproductive cough. A CT scan showed multiple brain, lung, adrenal gland and liver secondary lesions; moreover, it revealed a breast right nodule near the chest measuring 1...

BACKGROUND: Mucinous carcinoma (also known as colloid carcinoma) is a particular type of breast cancer characterized by the presence of extracellular mucin and is linked with a more favorable prognosis than invasive breast carcinoma of no special type. Mucinous carcinoma of the breast is an uncommon form of breast tumor, often presenting as a lobulated, moderately well circumscribed mass on mammography, sonography, and MRI imaging. It accounts for 1 to 7% of all breast cancers. Pure mucinous breast carcinomas are rare and account for about 2% of all primary breast carcinomas...

Neuroendocrine tumors (NET) are rare malignancies, with the most common site of origin being from the gastrointestinal tract, particularly the pancreas, small bowel and appendix. Pancreatic neuroendocrine tumors (PNETs) can be functional, hormone secreting tumors, and can have distinctive symptoms leading to the diagnosis. In contrast nonfunctional tumors, the majority of PNETs, usually present later either incidentally or due to tumor bulk symptoms. Currently Everolimus, an inhibitor of mammalian target of rapamycin (mTOR), is the most promising drug for patients with unresectable, metastatic disease, in progressive well-differentiated PNETs and many studies are ongoing to demonstrate its effects on the other neuroendocrine histotipes...

Neuroendocrine neoplasms (NEN) of the breast are specific tumor entities. According to the literature up to 5% of breast neoplasms are malignant epithelial neoplasms of the breast. They are defined by a neuroendocrine (NE) architecture and cytology combined with an expression of the neuroendocrine vesicle markers chromogranin A and/or synaptophysin. The diagnosis is supplemented by the receptor status and the proliferative activity. According to the World Health Organization (WHO) classification of 2012 the following groups of NEN are distinguished: (1) invasive breast carcinoma with NE differentiation, (2) well-differentiated neuroendocrine tumor (NET) and (3) poorly differentiated small cell carcinoma (NEC)...

BACKGROUND: The present study was designed to determine whether the Thinprep plus Papanicolaou stain (Thinprep) method is more sensitive than the Cytospin-coupled Wright-Giemsa (WG) stain (Cytospin) method in diagnosis of leptomeningeal metastasis (LM) from malignant solid tumors in cerebrospinal fluid (CSF). We also explored if the Thinprep method could be used in the differential diagnosis of the type of primary tumor cells based on the morphology of tumor cells in CSF samples. METHODS: The morphological features of tumor cells in fresh CSF samples were analyzed using both methods...

We performed immunohistochemical analysis of neuroendocrine breast cancer. The significance of this approach to differential diagnosis of this cancer form by detection of specific markers is demonstrated. The incidence of diagnosis of neuroendocrine breast cancer has increased 8-fold over 5 years. Neuroendocrine breast cancer is responsible for 3.4% of all breast cancer cases. The disease is significantly more incident in patients over 60. Neuroendocrine breast cancer is characterized by high expression of neuron-specific enolase (100%) and chromagranin A (57%)...
