Association of Peritumoral Radiomics With Tumor Biology and Pathologic Response to Preoperative Targeted Therapy for HER2 (ERBB2)-Positive Breast Cancer.

JAMA Netw Open 2019 Apr 5;2(4):e192561. Epub 2019 Apr 5.

Department of Biomedical Engineering, Case Western Reserve University, Cleveland, Ohio.

Importance: There has been significant recent interest in understanding the utility of quantitative imaging to delineate breast cancer intrinsic biological factors and therapeutic response. No clinically accepted biomarkers are as yet available for estimation of response to human epidermal growth factor receptor 2 (currently known as ERBB2, but referred to as HER2 in this study)-targeted therapy in breast cancer.

Objective: To determine whether imaging signatures on clinical breast magnetic resonance imaging (MRI) could noninvasively characterize HER2-positive tumor biological factors and estimate response to HER2-targeted neoadjuvant therapy. Read More

Department of Gastroenterology, Kitasato University School of Medicine, Kitasato University Hospital, Sagamihara, Kanagawa, Japan.

Pancreatic granular cell tumors (GCTs) are rare and making an imaging diagnosis of pancreatic GCT is difficult because it has no definite characteristics on contrast-enhanced computed tomography (CE-CT) or magnetic resonance imaging (MRI) owing to varying findings. We report about a 32-year-old woman who presented with an incidental finding of a pancreatic tumor with a past history of excision of a right forearm GCT nodule 12 years ago. CE-CT revealed a 23-mm-sized homogeneous low enhancement tumor in the arterial phase in the pancreatic body. Read More

Virginia Commonwealth University School of Dentistry, Richmond, VA, USA.

When faced with an uncertain clinical pathosis in the oral cavity, identifying the color of the mucosal lesion helps to narrow down a differential diagnosis. Although less common than red and white lesions, yellow lesions encompass a small group of distinct mucosal pathologic entities. Adipose tissue, lymphoid tissue, and sebaceous glands are naturally occurring yellow constituents of the oral cavity and become apparent with associated developmental or neoplastic lesions.

Introduction And Objective: Granular cell tumour (GCT) is a benign neoplasm of neural/schwannian origin, usually presenting as a single asymptomatic lesion, mainly located in the dermis and subcutaneous tissue or submucosa, although multiple tumours may occur. Microscopically, GCTs are composed of large cells with abundant eosinophilic, granular cytoplasm arranged in sheets, nests, cords or trabeculae. Based on the cytological characteristics and the presence of necrosis, three types are recognized: benign, atypical and malignant. Read More

Distinct Expression and Clinical Significance of Zinc Finger AN-1-Type Containing 4 in Oral Squamous Cell Carcinomas.

J Clin Med 2018 Dec 10;7(12). Epub 2018 Dec 10.

Instituto de Investigación Sanitaria del Principado de Asturias (ISPA), Instituto Universitario de Oncología del Principado de Asturias (IUOPA), Universidad de Oviedo, C/Carretera de Rubín, s/n, 33011 Oviedo, Asturias, Spain.

Zinc finger AN1-type containing 4 (ZFAND4) has emerged as a promising prognostic marker and predictor of metastasis for patients with oral squamous cell carcinoma (OSCC). However, further validation is fundamental before clinical implementation. Hence, this study evaluated the expression pattern of ZFAND4 protein expression by immunohistochemistry using an independent cohort of 125 patients with OSCC, and correlations with the clinicopathologic parameters and disease outcome.

Effect of experimentally induced hypertension on cerebellum of postmenopausal rat.

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

Department of Physiology, Faculty of Medicine, Minia University, Minia, Egypt.

Cerebellum seems to be a specific target for both the decrease of estrogen and hypertension in menopause. The aim of this study was to investigate the hypertension and menopause-induced changes in rat's cerebellar cortex and the possible mechanisms of these changes. Rats were divided into four groups: the sham-operated control (SC-group), the ovariectomized (OVX-group), the hypertensive (H-group), and the ovariectomized-hypertensive (OVX-H-group) group.

Unknown primary large-cell neuroendocrine tumor.

Autops Case Rep 2018 Apr-Jun;8(2):e2018025. Epub 2018 Jun 8.

a Centro Hospitalar de São João, Medical Oncology Department. Porto, Portugal.

Large-cell neuroendocrine tumors (NETs) are poorly differentiated malignancies of rare incidence and aggressive nature. NETs mostly arise in the lung followed by the gastrointestinal tract, although they are potentially ubiquitous throughout the body. Primary unknown NET has a worse prognosis and shorter survival comparing with other NETs, with limited available data in the literature concerning this subgroup. Read More

A CK1α Activator Penetrates the Brain and Shows Efficacy Against Drug-resistant Metastatic Medulloblastoma.

Clin Cancer Res 2019 Feb 28;25(4):1379-1388. Epub 2018 Nov 28.

Molecular Oncology Program, The DeWitt Daughtry Family Department of Surgery, University of Miami, Miller School of Medicine, Miami, Florida.

Purpose: Although most children with medulloblastoma are cured of their disease, Sonic Hedgehog (SHH) subgroup medulloblastoma driven by mutations is essentially lethal. Casein kinase 1α (CK1α) phosphorylates and destabilizes GLI transcription factors, thereby inhibiting the key effectors of SHH signaling. We therefore tested a second-generation CK1α activator against -mutant, -amplified medulloblastoma. Read More

Two Cases of Granular Cell Tumors that Clinically Mimicked Hypertrophic Scars and Keloids.

J Nippon Med Sch 2018 ;85(5):279-282

Department of Plastic, Reconstructive & Aesthetic Surgery, Nippon Medical School.

We report two cases of granular cell tumors (GCTs) arising on rare sites, namely, the nape and umbilicus. While GCTs have a very characteristic histology, their clinical signs and symptoms are non-specific. Therefore, it is extremely difficult to make a diagnosis of GCT on the basis of clinical findings only. Read More

Genetic ablation of Gpr37l1 delays tumor occurrence in Ptch1 mouse models of medulloblastoma.

Exp Neurol 2019 Feb 16;312:33-42. Epub 2018 Nov 16.

Institute of Cell Biology and Neurobiology, Italian National Research Council (CNR), I-00015, Monterotondo Scalo, Rome, Italy.

The G-protein coupled receptor 37-like 1 (Gpr37l1) is specifically expressed in most astrocytic glial cells, including cerebellar Bergmann astrocytes and interacts with patched 1 (Ptch1), a co-receptor of the sonic hedgehog (Shh)-smoothened (Smo) signaling complex. Gpr37l1 null mutant mice exhibit precocious post-natal cerebellar development, with altered Shh-Smo mitogenic cascade and premature down-regulation of granule cell precursor (GCP) proliferation. Gpr37l1 expression is downregulated in medulloblastoma (MB) and upregulated in glioma and glioblastoma tumors. Read More

Benign Oral Mucosal Lesions: Clinical and Pathological Findings Part I- Benign Oral Mucosal lesions.

J Am Acad Dermatol 2018 Nov 14. Epub 2018 Nov 14.

Department of Dermatology, Boston University School of Medicine, Boston, MA. Electronic address:

A diverse spectrum of benign oral mucosal lesions exists, presenting as either isolated oral findings or in association with dermatological conditions. Oral lesions can closely resemble one another; therefore, it is important for clinicians to be able to recognize their distinctive features and recognize benign versus malignant disease and when a biopsy is warranted. In this continuing medical education series, we review oral anatomy and the clinical attributes of several benign lesions of the oral cavity along with the appropriate management and therapeutic modalities.

Deep Learning Models Differentiate Tumor Grades from H&E Stained Histology Sections.

Conf Proc IEEE Eng Med Biol Soc 2018 07;2018:620-623

Aberration in tissue architecture is an essential index for cancer diagnosis and tumor grading. Therefore, extracting features of aberrant phenotypes and classification of the histology tissue can provide a model for computer-aided pathology (CAP). As a case study, we investigate the application of convolutional neural networks (CNN)s for tumor grading and decomposing tumor architecture from hematoxylin and eosin (H&E) stained histology sections of kidney.
