INTRODUCTION: Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas. PRESENTATION OF CASE: A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma...

Fibrous dysplasia is a benign developmental disorder of bone in which fibrous connective tissue containing abnormal bone with irregular trabeculae replaces normal cancellous bone. It may affect 1 (monostotic) or multiple bones (polyostotic). Polyostotic disease is the less common of the 2, occurring in only 20 to 25% of fibrous dysplasia patients and tending to affect those who are younger than 10 years of age; patients having this form tend to experience bone enlargement beyond normal skeletal maturation, which can cause pain, progressive damage, and increased risk of pathological fracture...

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...

PURPOSE: Optoacoustic imaging provides high spatial resolution and the possibility to image specific functional parameters in real-time, therefore positioning itself as a promising modality for various applications. However, despite these advantages, the applicability of real-time optoacoustic imaging is generally limited due to a relatively small field of view. METHODS: With this work, we aim at presenting a path towards panoramic optoacoustic tomographic imaging without requiring additional sensors or position trackers...

Ovarian epithelial type tumors of the testis have been a rare entity in clinic. Its' awareness and management remain a clinical challenge. We described a case of an 18-year-old, obese, boy who presented with scrotal enlargement. He underwent eversion of tunica vaginalis and resection of epidydimal mass. The histology of the resected sample showed ovarian epithelial type borderline tumor. We believe this case helps to strengthen awareness and management of this rare disease.

OBJECTIVE: Although percutaneous transluminal angioplasty is an effective therapy against vascular access failure in hemodialysis patients, recurrent stenosis imposes enormous burden for hemodialysis patients. A nitinol scoring element-equipped helical balloon catheter (AngioSculpt® ) has been altered the landscape for treating several vascular diseases. It is not, however, fully elucidated whether AngioSculpt for advanced vascular access stenosis, difficult to expand by conventional balloons, successfully provides bailout angioplasty...

Enlargement of a self-assembled metal-organic rhomboid is achieved via the organic solid state. The solid-state synthesis of an elongated organic ligand was achieved by a template directed [2+2] photodimerization in a cocrystal. Initial cocrystals obtained of resorcinol template and reactant alkene afforded a 1:2 cocrystal with the alkene in a stacked yet photostable geometry. Cocrystallization performed in the presence of excess template resulted in 6:4 cocrystal composed of novel discrete 10-component hydrogen-bonded 'super-assemblies' wherein the alkenes undergo a head-to-head [2+2] photodimerization...

A giant right coronary artery aneurysm (60 × 70 mm in size) was incidentally found by chest X-ray as an abnormal right atrial enlargement, and it needed surgical resection. Although the majority of giant coronary artery aneurysms present with symptoms of coronary ischemia, this case presented without any specific symptom. This study indicates that when chest X-ray shows abnormal atrial enlargement, a differential diagnosis of giant coronary artery aneurysm may need to be considered.

A 2-year-old Boer doe was presented with respiratory distress and severe inspiratory dyspnea. Cervical and thoracic radiographs revealed a marked retropharyngeal soft tissue mass effect, several mineralized pharyngeal and retropharyngeal structures, and a pulmonary mass. Computed tomography (CT) revealed a severely enlarged right medial retropharyngeal lymph node, which caused laryngeal compression, leading to upper airway obstruction. Multiple cervical and thoracic lymph nodes, and the pulmonary mass had an irregular layered/laminated pattern of mineralization...

Secondary alveolar septa are mostly generated after birth in humans and in mice this is completely accomplished postnatally, when mechanical stresses vary as airspace pressure oscillates. Alveolar mesenchymal cells deposit elastic fibers which limit cellular strain, but while the elastic fiber network is incomplete, this function is also served by the intracellular cytoskeleton. Intermediate filament proteins support deformation during cellular division and migration, which occur during septal elongation. Because platelet-derived growth factor-alpha (PDGFRα) signaling is essential for alveolar septation, we hypothesized that neuropilin-1 (NRP1) may link PDGFRα to cytoskeletal deformation...

During mammalian heart development, restricted myocardial Bmp2 expression is a key patterning signal for atrioventricular canal specification and the epithelial-mesenchyme transition that gives rise to the valves. Using a mouse transgenic line conditionally expressing Bmp2, we show that widespread Bmp2 expression in the myocardium leads to valve and chamber dysmorphogenesis and embryonic death by E15.5. Transgenic embryos show thickened valves, ventricular septal defect, enlarged trabeculae and dilated ventricles, with an endocardium able to undergo EMT both in vivo and in vitro...
