Cat scratch colon and cecal barotrauma perforation during colonoscopy with CO2 insufflation.

Background: Cecal perforation from barotrauma is a rare complication of colonoscopy, even with the use of CO₂ insufflation, which is generally preferred over room air due to its rapid absorption and reduced patient discomfort.

Case Report: A 64-year-old woman with hypertension and dyslipidemia underwent a routine colonoscopy with CO₂ insufflation. Multiple diverticula were noted, and upon reaching the cecum, several parallel linear lesions with spontaneous bleeding, consistent with "cat scratch" colon, were observed.

A rare case of pancreatic pseudocyst-portal vein fistula in a patient with chronic pancreatitis.

A 60-year-old female with chronic pancreatitis and a history of splenectomy presented with epigastric pain, vomiting, and asthenia. Elevated pancreatic enzymes and CT imaging revealed a pseudocyst in the pancreatic head with suspected communication to the portal vein, confirmed by MR Cholangiopancreatography and endoscopic ultrasound (EUS). EUS-guided puncture revealed high amylase levels.

Lumen-apposing metal stent for malignant gastrointestinal stricture.

We present a case of gastro-jejunal anastomotic stenosis due to the progression of malignant disease, successfully treated endoscopically by placing a lumen-apposing metal stent. This case illustrating the successful use of a lumen-apposing metal stent in a complex clinical scenario. This approach can significantly improve patient outcomes, especially in those who are poor surgical candidates or have advanced disease.

Clear cell renal cancer metastasis - A case of delayed diagnosis.

Renal cell carcinoma represents about 90% of all primary renal neoplasms. Clear cell renal cell carcinoma is the most common histological type, characterized by an aggressive clinical course due to its tendency to metastasize. Metastases are typically diagnosed on average 5 years after oncological surgery.

Gastric neuroendocrine tumor presenting with carcinoid syndrome.

Carcinoid tumors are rare neoplasms, most frequently found in the gastrointestinal tract, responsible for the production of neuroendocrine mediators. Carcinoid syndrome is even rarer and consists of a set of symptoms characteristic of the release of these mediators into the systemic circulation. We present an interesting case of a patient with carcinoid syndrome as a late manifestation of a gastric neuroendocrine tumor with, highlighting the importance of knowing how to identify the carcinoid syndrome.

Anorectal melanoma: a rare entity.

Anorectal melanoma is a rare malignant tumor with the potential of simulating a benign anorectal disease, making its diagnosis difficult. We describe a case of anorectal melanoma, in which the interpretation of symptoms as hemorrhoidal disease delayed diagnosis and appropriate intervention.

Esophagitis dissecans superficialis: a rare endoscopic finding.

Esophagitis dissecans superficialis is an extremely rare benign illness. Although an association with medications, skin conditions, heavy smoking, and physical trauma has been reported, most cases remain unexplained. We present a previously healthy 42-year-old woman found to have EDS secondary to trauma.

The medical response to burn disasters in Europe: A scoping review.

Introduction: A burn disaster is defined by a mass casualty involving a large number of severely burned victims. Several countries have been confronted with these mass casualties and have developed national burn practice guidelines. This study presents a comprehensive review of the literature related to the benefits and conditions required for the introduction of a burn plan and identify successful strategies in Europe to apply in Portugal.
