Knowledge of staining pattern of certain immunostains might be useful in the classification of cutaneous adnexal tumors that can have clinical importance. We studied GATA3 and MYB expression in archival materials of 220 adnexal tumors comprised of sebaceous carcinomas, follicular tumors, apocrine carcinoma, predominantly apocrine tumors, predominantly eccrine tumors, and others including adenoid cystic carcinomas. Nuclear GATA3 expression was seen in 70% (153/220) of cases, including sebaceous carcinoma (93%), apocrine carcinoma (93%), follicular neoplasms (100%), and predominantly apocrine neoplasms (69%), yet only 38% of predominantly eccrine neoplasms...

Identification of the associations between microRNA molecules and human diseases from large-scale heterogeneous biological data is an important step for understanding the pathogenesis of diseases in microRNA level. However, experimental verification of microRNA-disease associations is expensive and time-consuming. To overcome the drawbacks of conventional experimental methods, we presented a combinatorial prioritization algorithm to predict the microRNA-disease associations. Importantly, our method can be used to predict microRNAs (diseases) associated with the diseases (microRNAs) without the known associated microRNAs (diseases)...

BACKGROUND: Population-based data on the development of kidney cancer as a second malignant neoplasm following the diagnosis of other common malignancies are rare. This clinical scenario has been evaluated within the Surveillance, Epidemiology, and End Results (SEER) database. MATERIALS AND METHODS: The SEER-9 database (1973-2013) was queried using the SEER*Stat program to determine the standardized incidence ratios (SIRs) of kidney cancer development following each one of 10 common invasive malignancies (colorectal, breast, prostate, lung, thyroid, corpus uteri, urinary bladder, kidney/renal pelvis, cutaneous melanoma, and non-Hodgkin lymphoma)...

An adenomyoepithelioma of the breast is a rare tumor characterized by biphasic proliferation of both epithelial and myoepithelial cells. This tumor is generally considered as a benign neoplasm, and there are few reports describing the imaging features of this tumor through (18) F-fluorodeoxyglucose positron emission tomography (FDG-PET). Here, we report a case of an adenomyoepithelioma that showed strong uptake of FDG on PET similar to that observed with a malignant tumor. A 73-year-old woman presented to our hospital with a 3...

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare adnexal tumor of the skin with low-grade cytological features and neuroendocrine differentiation. It has a predilection for the skin of the eyelid, but has also been reported in the face and rarely extra-facial locations. The tumor is seen more frequently in women and on average affects the elderly. It is histologically and immunohistochemically analogous to solid papillary carcinoma of the breast/endocrine ductal carcinoma in situ with a nodular, solid, papillary, and/or cribriforming architecture, neuroendocrine differentiation, and mucin production...

We aimed to assess changes in the total effective xenoestrogen burden (TEXB) -a biomarker of combined effect of mixtures of xenoestrogens- in breast cancer patients at surgery (breast adipose tissue) and at different time points during an 18-month follow-up (abdominal adipose tissue), and to analyze the potential influence of socio-demographic, reproductive, tumor, and treatment characteristics on TEXB levels. TEXB-alpha (due to persistent organohalogenated chemicals) and TEXB-beta (due mainly to endogenous estrogens) were quantified in 44 women...

We reviewed available evidence on coffee drinking and the risk of all cancers and selected cancers updated to May 2016. Coffee consumption is not associated with overall cancer risk. A meta-analysis reported a pooled relative risk (RR) for an increment of 1 cup of coffee/day of 1.00 [95% confidence interval (CI): 0.99-1.01] for all cancers. Coffee drinking is associated with a reduced risk of liver cancer. A meta-analysis of cohort studies found an RR for an increment of consumption of 1 cup/day of 0.85 (95% CI: 0...

OBJECTIVE: Emerging data have shown an increased risk of malignancy among patients diagnosed with systemic sclerosis (SSc) so identification of risk factors linking both disorders might have prognostic implications. The aim of this study was to assess the clinical and treatment-related risk factors for cancer in a single-center cohort of patients with SSc. METHODS: Demographic, clinical, capillaroscopic, immunological and treatment-related data from 432 consecutive SSc patients were retrospectively analyzed...

INTRODUCTION: Pancreatic cysts are often observed incidentally on abdominal computed tomography (CT). For cysts involving intracystic nodules, malignant neoplasms such as intraductal papillary-mucinous carcinoma (IPMC) should be suspected. In contrast, cholesterol granuloma (CG) rarely occurs in the pancreas, and CG-associated autoimmune pancreatitis (AIP) has not yet been reported. To our knowledge, this is the first reported case of AIP with CG mimicking IPMC. PRESENTATION OF CASE: A 56-year-old woman underwent abdominal CT for preoperative breast cancer screening...

INTRODUCTION: Phyllodes tumors are uncommon biphasic fibroepithelial neoplasms of the breast of varying malignant potential occurring in middle aged women. They exhibit diverse biological behavior. Margin free excision is the mainstay of treatment. CASE PRESENTATION: A 27 year-old lady was referred with a painless ulceroproliferative right breast lesion which had rapidly progressed over six months. Three years back, she had been diagnosed with a borderline phyllodes tumor and underwent a wide local excision followed by a right mastectomy for recurrence...

Whether patients with non-functioning pituitary adenoma (NFPA) are at increased risk of developing malignant tumours has been sparsely studied and is a matter of debate. In this study, we have investigated the incidence of malignant tumours in a large and unselected group of patients with NFPA. The study was nationwide and included all patients diagnosed with NFPA between 1987-2011 (n=2,795) in Sweden, identified in the National Patient Register. Malignant tumours, occurring after the NFPA diagnosis, were identified in the Swedish Cancer Register between 1987-2014...

INTRODUCTION: Fibroepithelial tumours are a heterogeneous group of biphasic neoplasms consisting of a proliferation of both epithelial and stromal components. Fibroadenoma (FA) and Phyllodes Tumour (PT) constitute the major entities. It is crucial to distinguish benign from borderline PT (low grade malignant PT), because the former do not metastasize, have a lesser risk of local recurrence and initial local recurrences are histologically benign in almost all instances. Multiple Immunohistochemical (IHC) markers are being studied to find their utility in grading the PT accurately for planning proper treatment...

Chronic myeloid leukemia (CML) is characterized by increased and unregulated proliferation of granulocytic lineage in the bone marrow and presence of these immature myeloid cells in the peripheral blood with presence of Philadelphia (Ph) chromosome. Tyrosine kinase inhibitors are the most important drugs in the CML therapy and provide long disease-free survival. Due to the increased survival of CML patients with continual administration of these drugs, the chance of development of secondary malignancies may increase...

The objective of this review was to identify recurrences (ipsilateral, contralateral, metastases and deaths) occurring after controlled ovarian hyperstimulation (COH) or cryopreservation of ovarian tissue (CPTO) for patients treated for a breast cancer. METHODS: We performed a bibliographical research through the Pubmed/Medline database, including all the references from January 2006 until September 2016, in French or in English, after exclusion of animal studies. The keywords association "breast neoplasms", "fertility preservation", "reproductive techniques", "ovarian cryopreservation" and "in vitro fertilization" allowed the selection of 852 publications among which only 6 were selected because they included data on recurrence and long term follow up...

Carcinomas arising from breast hamartomas are exceedingly rare. We present the first reported case of an African-American female presenting with a right breast lump and a subsequent mammogram suggestive of a hamartoma. She later underwent lumpectomy and was found to have HER2+ invasive ductal carcinoma (IDC) arising from a hamartoma. She was amenable to HER2-targeted trastuzumab, hormone therapy and adjuvant radiation but declined chemotherapy. In a review of the literature, IDC is the predominant neoplastic type found in hamartomas...

REVIEW
Shin-Ichi Ansai
This article reviews several topics regarding sweat gland and sebaceous neoplasms. First, the clinicopathological characteristics of poroid neoplasms are summarized. It was recently reported that one-fourth of poroid neoplasms are composite tumors and one-fourth are apocrine type lesions. Recent progress in the immunohistochemical diagnosis of sweat gland neoplasms is also reviewed. CD117 can help to distinguish sweat gland or sebaceous tumors from other non-Merkel cell epithelial tumors of the skin. For immunohistochemical differential diagnosis between sweat gland carcinoma (SGC) other than primary cutanesous apocrine carcinoma and skin metastasis of breast carcinoma (SMBC), a panel of antibodies may be useful, including p63 (SGC(+) , SMBC(-) ), CK5/6 (SGC(+) , SMBC(-) ), podoplanin (SGC(+) , SMBC(-) ) and mammaglobin (SGC(-) , SMBC(+) )...

FOXA1 is a transcription factor essential for the binding and action of other transcription factors on the chromatin. It is the major regulator of endoderm differentiation. It has important roles in breast, prostate and endometrial cancer. It has never been studied in ovarian tumours. The aim of this study was to investigate its expression in ovarian epithelial neoplasms. A total of 195 primary ovarian epithelial borderline or malignant tumours were immunohistochemically studied for the expression of FOXA1...

Zinc is the catalytic component of proteins that regulate responses to DNA damage, intracellular signaling enzymes, and matrix metalloproteinases, which are important proteins in carcinogenesis. The objective of this review is to bring current information on the participation of zinc and matrix metalloproteinases types 2 and 9 in mechanisms involved in the pathogenesis of breast cancer. We conducted a literature review, in consultation with the PubMed, Lilacs, and Scielo databases. The zinc and cysteine residues are structural elements shared by all members of the family of matrix metalloproteinases, and these proteins appear to be involved in the propagation of various types of neoplasms, including breast cancer...
