Summary
This case study details a rare benign esophageal schwannoma, a non-cancerous tumor. Surgical resection was successful, with no recurrence observed in this patient.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Benign esophageal tumors are rare, comprising about 2% of all esophageal tumors.
- Leiomyomas are the most common type of benign esophageal tumor, while schwannomas are exceptionally rare.
- Esophageal schwannomas can present with symptoms like dysphagia and chest discomfort.
Observation:
- A 55-year-old woman presented with palpitations and dysphagia.
- Imaging revealed a large mediastinal tumor compressing the esophagus.
- Endoscopy showed a smooth, elevated lesion, and biopsy confirmed schwannoma.
Findings:
- Histopathology showed spindle cells with palisading nuclei.
- Immunohistochemistry was positive for S100 protein and negative for αSMA, CD34, and CD117.
- The diagnosis of benign esophageal schwannoma was confirmed.
Implications:
- Large benign esophageal schwannomas may necessitate extensive surgical resection, such as subtotal esophagectomy.
- Accurate diagnosis through biopsy and immunohistochemistry is crucial for appropriate management.
- Successful surgical outcomes are achievable for benign esophageal schwannomas, with low recurrence rates.

01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:30Esophageal Strictures-I: Introduction
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
01:22Esophageal Perforation-I: Introduction
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...
