Summary
Schwannomas, also known as neurilemmomas, are rare, slow-growing tumors originating from Schwann cells. Diagnosis in these two presented cases was confirmed only after surgical tumor removal.
Area of Science:
- Oncology
- Neurosurgery
- Pathology
Background:
- Schwannomas (Neurilemmomas) are benign, encapsulated, slow-growing perineural tumors.
- These tumors originate from the Schwann cell sheath, a component of neuro-ectodermal tissue.
Purpose of the Study:
- To present two rare cases of Schwannoma (Neurilemmoma).
- To highlight the diagnostic challenges and confirm diagnosis post-excision.
Main Methods:
- Surgical excision of the tumors.
- Histopathological examination of the excised tissue (implied).
Main Results:
- Diagnosis of Schwannoma (Neurilemmoma) was established in both cases.
- Confirmation of diagnosis was achieved post-surgical tumor removal.
Conclusions:
- Schwannomas are rare neuro-ectodermal tumors.
- Delayed diagnosis, confirmed post-excision, can occur in rare cases of Schwannoma.

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...

01:27Esophageal 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)...
01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
