Infantile choriocarcinoma (ICC) is a rare, highly malignant form of gestational trophoblastic neoplasia. Rapid diagnosis and initiation of treatment are paramount in reaching a successful outcome. Patients with these tumors typically present with a triad of anemia, hepatomegaly, and precocious puberty. Cutaneous manifestations of ICC are extraordinarily rare with few documented cases. Here, we describe a male neonate who presented to our Dermatology clinic with a rapidly growing, markedly vascular glabellar mass associated with abnormal laboratory values suggestive of Kasabach-Merritt phenomenon...

BACKGROUND: Colorectal serrated lesions (SLs) are important premalignant lesions whose clinical and biological features are not fully understood. AIMS: We aimed to establish accurate colonoscopic diagnosis and treatment of SLs through evaluation of associations among the morphological, pathological, and molecular characteristics of SLs. METHODS: A total of 388 premalignant and 18 malignant colorectal lesions were studied. Using magnifying colonoscopy, microsurface structures were assessed based on Kudo's pit pattern classification system, and the Type II pit pattern was subcategorized into classical Type II, Type II-Open (Type II-O) and Type II-Long (Type II-L)...

BACKGROUND AND AIMS: There are few prospective data about the use of surveillance colonoscopy and the risk of recurrent neoplasia in first degree relatives (FDRs) of colorectal cancer (CRC) patients. We examined the use and yield of surveillance colonoscopy in a population-based screening program (Trentino, Italy) METHODS: 1252 FDRs have been included in this study. We calculated compliance (percentage of FDRs who underwent surveillance colonoscopy among those eligible), appropriateness of colonoscopy (appropriate if performed within 6 months of the guidelines recommended interval) and diagnostic yield for neoplasia...

Human papilloma virus (HPV)-associated cancer is a significant global health burden and despite the presence of viral transforming antigens within neoplastic cells, therapeutic vaccinations are ineffective for advanced disease. HPV positive TC1 cells are susceptible to viral oncolysis by MG1-E6E7, a custom designed oncolytic Maraba virus. Epitope mapping of mice vaccinated with MG1-E6E7 enabled the rational design of synthetic long peptide (SLP) vaccines against HPV16 and HPV18 antigens. SLPs were able to induce specific CD8+ immune responses and the magnitude of these responses significantly increased when boosted by MG1-E6E7...

BACKGROUND: A comprehensive understanding of cancer has been furthered with technological improvements and decreasing costs of next-generation sequencing (NGS). However, the complexity of interpreting genomic data is hindering the implementation of high-throughput technologies in the clinical context: increasing evidence on gene-drug interactions complicates the task of assigning clinical significance to genomic variants. METHODS: Here we present a method that automatically matches patient-specific genomic alterations to treatment options...

BACKGROUND: Mutations activating the α subunit of heterotrimeric Gs protein are associated with a number of highly specific pathological molecular phenotypes. One of the best characterized is the McCune Albright syndrome. The disease presents with an increased incidence of neoplasias in specific tissues. MAIN BODY: A similar repertoire of neoplasms can develop whether mutations occur spontaneously in somatic tissues during fetal development or after birth. Glands are the most "permissive" tissues, recently found to include the entire gastrointestinal tract...

The irritable bowel syndrome (IBS) counts among the most prevalent chronic diseases. Clinically, the IBS is characterized by abdominal symptoms combined with irregular defecation, which are not explained by routine diagnostic tests. IBS is often triggered by enteric bacterial infections, and its pathogenesis involves disturbed enteric, gut-brain, and cerebral mechanisms. Diagnostic work-up must aim to establish a positive IBS diagnosis, and to exclude serious underlying differential diagnoses (such as neoplasia, inflammatory bowel disease, celiac disease and others)...

The left ventricle is a less frequent location of cardiac myxomas overall. Meanwhile, cardiac myxomas related to Carney complex (CNC), which is a multiple neoplasia syndrome involving cardiac, endocrine, neural, and cutaneous tumours, more frequently occur in the left ventricle compared with sporadic cardiac myxomas. Herein, we report a case of a 20-year-old woman with CNC who underwent complete surgical excision of a large and mobile left ventricular myxoma. In our case, echocardiography performed 4 years earlier was normal...

OBJECTIVE: A growing body of evidence indicates that patients with colorectal serrated lesions especially advanced serrated lesions (ASLs) are at risk of subsequent malignancy. This study aimed to provide more information for endoscopists for the management of ASLs by analyzing the clinicopathological features of ASLs, and the association between the presence of ASL and synchronous advanced colorectal neoplasia (sACN) in China. METHODS: We performed a retrospective cross-sectional study of data from 38,981 symptomatic patients who underwent colonoscopy between January 2010 and March 2016...

BACKGROUND: Membrane-associated guanylate kinase, WW and PDZ domain-containing protein 2 (MAGI2) promotes the activity of phosphatase and tensin homolog (PTEN). Recent studies suggest that dysregulation of this signaling pathway has a role in prostate carcinogenesis. Our study aims to determine the prognostic significance of MAGI2 expression in prostate cancer. METHODS: Tissue microarrays from 51 radical prostatectomy cases including benign prostatic tissue, high grade prostatic intraepithelial neoplasia (HGPIN), and adenocarcinoma were constructed...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

BACKGROUND: The diagnostic accuracy of colposcopy is poor for detecting precancerous cervical lesions. OBJECTIVES: We assessed the performance of colposcopy for identifying cervical intraepithelial neoplasia grade 2 or worse (CIN2+), before and after including a dynamic spectral imaging (DSI) map that quantifies and maps acetowhitening to assist subsequent biopsy of suspicious lesions. METHODS: Four hundred and twenty-five women were examined at a multi-center setting in Wales, of which 393 women were included in the final analysis...

A 10-year-old female Australian Cattle Dog was referred for investigation of a mediastinal mass. During clinical examination, a mandarin- sized mass was detected ventrally of the trachea. According to computed tomographic (CT) findings and cytology of a fine-needle aspirate, thyroid neoplasia was suspected. The assumed tumour affected the left thyroid gland and was staged as stadium II because of enlargement of the ipsilateral cervical and retropharyngeal lymph nodes. The left thyroid, including the parathyroid gland, was removed surgically with a guarded prognosis...

The content of mRNA of the histidine-rich glycoprotein (HRG), a potential marker of malignant neoplasia, which can be used in differential diagnosis of breast tumors, was determined in 110 breast tumor biopsy samples. The presence of HRG mRNA did not depend on the cancer type, on the preoperative treatment or its absence, as well as on the tumor progression stage and the presence of metastases.

Gestational choriocarcinoma is a rare and aggressive type of gestational trophoblastic neoplasia, which is characterized by early vascular invasion and widespread metastases. Choriocarcinoma metastasizes hematogenously, and bleeding from metastases is common. Splenic rupture from a metastatic tumour is exceedingly rare, with only a few reports. We report a case of a 41-year-old female presenting with acute abdomen and haemorrhagic shock secondary to splenic rupture from metastatic choriocarcinoma, which was managed with emergency laparoscopic splenectomy...

Copy number variations (CNV), an important genetic mechanism in inherited tumor genetics, can affect large genetic regions or can be limited to smaller regions within genes, such deletions of single exons. Such exon deletions can be challenging to identify and sequencing can be normal in these cases. Multiplex ligation dependent probe amplification (MLPA) can identify CNV of individual exons. Mutations in the MAX gene are associated with a risk of sporadic and hereditary pheochromocytoma. As mutations in other pheochromocytoma related genes can also cause pituitary tumors (3P-Association), we studied whether MAX exon deletions were involved in the etiology of patients with an unexplained association of multiple endocrine neoplasia including pituitary adenoma and pheochromocytoma...
