Neutrophils form neutrophil extracellular traps (NETs) of decondensed DNA and histones that trap and immobilize particulate matter and microbial pathogens like bacteria. NET aggregates reportedly surround and isolate large objects like monosodium urate crystals, which cannot be sufficiently cleared from tissues. In the setting of acute necrotizing pancreatitis, massive tissue necrosis occurs, which is organized as pancreatic pseudocysts (1). In contrast to regular cysts, these pseudocysts are not surrounded by epithelial layers...

The formation of aortic thrombi is an extremely rare complication of acute pancreatitis. Here we report a case of acute pancreatitis complicated by a paraesophageal pseudocyst, necrotizing mediastinitis, and the formation of multiple thrombi in the ascending aorta. The patient was successfully treated by surgical therapy, which included extensive debridement of the mediastinum and removal of the aortic thrombi under cardiopulmonary bypass. Although esophageal resection was not carried out concomitantly, the lesions were resolved and the patient remained free of complications over 2 years of follow-up care...

Pseudocyst is a common complication of Acute and chronic pancreatitis. However, its extension into the mediastinum is a rare entity. We present a case of 52 years male with acute on chronic pancreatitis (alcohol related) who presented with dysphagia and dyspnoea and was found to have a pancreatic pseudocyst extending upto the neck. Ultrasound fails to pick up mediastinal pseudocysts and requires additional imaging modalities - CT and MRI. Management of Mediastinal pseudocyst depends upon underlying etiology, ductal anatomy, size of the pseudocyst, and availability of expertise...

Auricular pseudocysts are uncommon benign lesions of the pinna. The etiology is not well understood but repeated trauma is considered as a possible trigger. Exact diagnosis is important to avoid overtreatment with disfigurement. Various surgical approaches can be used in accordance to the stage of the lesion. Minor invasive procedures provide good results with low recurrence rates.

Lead toxicity in adults is characterized by nonspecific symptoms of abdominal pain, vomiting, constipation, fatigue, and weight loss. We present a case of severe lead toxicity that developed subacutely, causing quadriparesis 9 years after a gunshot wound with retained bullet fragments. The onset of symptoms may have been related to the development of a pseudocyst. The long interval between the gunshot wound and the onset of symptoms contributed to a delay in suspecting that the retained bullet was a source of lead toxicity...

Nontuberculous mycobacteria (NTM) are a rare cause of ventriculoperitoneal shunt infections. We describe the isolation and identification of a novel, rapidly growing, nonpigmented NTM from an abdominal cerebrospinal fluid pseudocyst. The patient presented with fevers, nausea, and abdominal pain and clinically improved after shunt removal. NTM identification was performed by amplicon and whole-genome sequencing.

Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms that arise in the gastrointestinal tract, accounting for ~1% of gastric malignancies. The present study reports the case of a GIST of the stomach in a 75-year-old man who presented with abdominal distension and anorexia for 1 month. Gastroscopy was unremarkable. Ultrasound and computed tomography (CT) scans showed a giant intraabdominal cystic lesion of unknown origin. The lesion was initially believed to be a duplication cyst, a pancreatic pseudocyst or a liver cyst in the pre-operative diagnosis...

The use of lasers in skin diseases is quite common. In contrast to other laser types, medical literature about 980 nm ultrapulsed diode laser is sparse in dermatology. Herein, we report the use of ultrapulsed diode 980 nm laser in 300 patients with vascular lesions, cysts and pseudocysts, infectious disease, and malignant tumors. This laser is a versatile tool with excellent safety and efficacy in the hands of the experienced user.

Cholelithiasis is the most common cause of acute pancreatitis, accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned, the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management, including cholecystectomy, endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy, or no definitive treatment...

Interventional endoscopy is a field that continues to grow rapidly. A novel prototype forward-viewing echoendoscope (FV-EUS) has been recently developed in an attempt to overcome some of the limitations of conventional curved linear-array echoendoscopes (OV-EUS). We present a case of a successful endoscopic ultrasound-guided drainage of a pancreatic pseudocyst using a forward-viewing echoendoscope. Although the utilization use of this newly developed echoendoscope has not yet become widespread, its unique characteristics can help to easily perform routine therapeutic procedures and contribute to the expansion of interventional endoscopic utrasoundultrasound...

Complete congenital absence of the omentum is very rare with only one previously reported case. We present a unique case of the management of a pregnant woman with a large pelvic pseudocyst caused by complications related to congenital absence of omentum, resulting in acute kidney injury, likely secondary to acute compartment syndrome. This case highlights the importance of considering acute compartment syndrome in critically unwell pregnant women and reiterates the need to measure intra-abdominal pressure when clinically indicated...
