#1
Adesh A Ramdass, Mike Yao, Suneetha Natarajan, Parampreet K Bakshi
BACKGROUND Vagus nerve schwannoma is a benign neoplasm that usually presents as an asymptomatic slow growing mass, and its presentation as a neck mass is rare. The diagnosis can be difficult to make and complete surgical excision is challenging due to the proximity of the vagus nerve fibers from which it originates. The most common symptom associated with vagus nerve schwannoma arising in the neck is hoarseness due to vocal cord palsy. CASE REPORT We report a case of a 55-year-old woman who presented to the clinic complaining of throat irritation and feeling of something stuck in her throat for the past three months...

BACKGROUND Primary mediastinal non-seminomatous germ cell tumors (NSGCTs) are aggressive and carry a poor five-year disease free survival rate even with aggressive treatment. We describe a young adult male with primary mediastinal NSGCT presenting with airway obstruction and superior vena cava syndrome (SVCS). CASE REPORT The patient presented with four weeks of nonproductive cough, weight loss, and right-sided pleuritic chest pain. Chest computed topography (CT) imaging demonstrated a right-sided mediastinal mass determined as a yolk sac tumor on biopsy...

BACKGROUND Spindle cell oncocytoma (SCO) is a rare nonfunctioning neoplasm of the adenohypophysis, and was first described in 2002. SCO has been categorized as a separate entity by the 2007 World Health Organization (WHO) and is classified as a Grade 1 tumor of the central nervous system (CNS). Review of the literature has shown that 33 cases of SCO have been reported to date, and most of them presented with a mass effect or with panhypopituitarism. However, all reported cases have described the tendency of SCO to be hypervascular on imaging and histology...

BACKGROUND The treatment of locally advanced non-small cell lung cancer involves a combination of chemotherapy, surgery, and radiotherapy. Each case is discussed and the best strategy is chosen individually, following international guidelines. CASE REPORT A 37-year-old man was diagnosed with locally advanced broncho-pulmonary adenocarcinoma (stage IIIA). The disease was stable after 2 cycles of cisplatin plus Navelbine used as neoadjuvant therapy. FISH analysis revealed an ALK rearrangement. The patient then received unlicensed crizotinib as second-line neoadjuvant treatment, which led to an almost complete radiological and metabolic response...

Masanori Sando, Masaki Terasaki, Yoshichika Okamoto, Kiyoshi Suzumura, Tomonori Tsuchiya
BACKGROUND Ultrasound (US) or computed tomography (CT)-guided biopsy of intra-abdominal lymph nodes is minimally invasive; however, percutaneous procedures are often difficult to perform because of the location and size of the lymph nodes. In many cases, this approach may result in insufficient specimens necessary to evaluate histopathology. In such cases, laparoscopic biopsy is useful to obtain adequate specimens, regardless of the location and size of the lymph nodes. Additionally, laparoscopic biopsy is an approach that can avoid the possible complications associated with a laparotomy...

BACKGROUND Postoperative bile duct leak following hepatobiliary and pancreatic surgery can be intractable, and the postoperative course can be prolonged. However, if the site of the leak is in the distal bile duct in the main biliary tract, the therapeutic options may be limited. Injection of absolute ethanol into the bile duct requires correct identification of the bile duct, and balloon occlusion is useful to avoid damage to the surrounding tissues, even in cases with non-communicating biliary fistula and bile leak...

BACKGROUND In Primary Myelofibrosis (PMF; a clonal disorder arising from the neoplastic transformation of early hematopoietic stem cells) patients, spinal cord compression (SCC) is a common complication or even a presentation symptom due to extramedullary hematopoiesis (EMH). However, a case of SCC caused by a spinal abscess is unusual. To the best of our knowledge, this is the first case report of this rare condition. CASE REPORT We are reporting the case of a 50-year-old male with primary myelofibrosis and long-standing splenomegaly with back pain as a presenting symptom who was found to have spinal cord compression...

BACKGROUND Recently, the use of cardiac implantable electrophysiological devices (CIEDs) has increased. Advances in medical technology, an increasingly aging population, increases in clinical indications, and expanded medical insurance coverage for these devices have all contributed to this trend. Infection is considered to be one of the most serious complications of CIEDs and carries a significant risk of morbidity and mortality. Although infection with Staphylococcus sp. accounts for the majority of cases, other bacteria have been implicated as causative agents of infection of CIEDs...

BACKGROUND Percutaneous catheter radiofrequency ablation (RFA) and cryoablation of the left atrium and pulmonary vein ostia have become successful therapeutic modalities in the management of atrial fibrillation. Atrio-esophageal fistula is a rare complication. Awareness of complication risk is imperative because without prompt diagnosis and urgent surgical intervention, the outcome is often fatal. We present 3 cases of atrio-esophageal fistula following percutaneous catheter radiofrequency ablation (RFA). CASE REPORT Case 1: A 72-year old white male presented 27 days after percutaneous RFA for atrial fibrillation with fever, altered mental status, and melena...

BACKGROUND Recurrent respiratory papillomatosis (RRP), caused by human papillomavirus (HPV), is the most common benign neoplasm of the larynx and central airways. RRP has a significant impact on quality life and high annual costs to healthcare. Currently, there is no cure for RRP, leading to repeated debulking operations for symptomatic palliation. Various local adjuvant therapies have also been studied with mixed efficacy. HPV oncogene products increase expression of vascular endothelial growth factor (VEGF) providing a potential target for treatment of RRP...

BACKGROUND Type 1 autoimmune pancreatitis (AIP), also known as lymphoplasmacytic sclerosing pancreatitis (LPSP), is a rare cause of chronic pancreatitis, characterized by a fibro-inflammatory process. However, patients with AIP may have a good response to corticosteroid therapy. We describe a Tunisian patient with AIP that was confirmed to be an IgG4-related disease (IgG4-RD). CASE REPORT We describe a case of a 70-year-old man who was admitted to hospital for obstructive jaundice and abdominal pain. Serum liver function tests were abnormal and upper abdominal computed tomography (CT) imaging showed diffuse pancreatic swelling and strictures of the main pancreatic duct without any focal lesion...

BACKGROUND Phyllodes tumor (PT) is a rare neoplasm of the breast. Concomitant PT with invasive ductal carcinoma (IDC) is an even rarer occurrence. When ductal carcinoma in situ (DCIS) or IDC are detected within the specimen, the management changes from wide local excision to further staging work-up, including sentinel node biopsy and radiation. CASE REPORT We report the case of a 70-year-old presented with right breast mass whose pathology showed benign PT with concomitant IDC and DCIS. The patient elected for a wide excision of the mass with sentinel lymph node biopsy, which did not show any involvement...
