Summary
This study reports the first female case of laryngeal myxoma, a rare benign tumor often misdiagnosed as a vocal polyp. Surgical excision with surrounding tissue is crucial for preventing recurrence of this slow-growing connective tissue tumor.
Area of Science:
- Otolaryngology
- Pathology
- Oncology
Background:
- Laryngeal myxomas are rare benign tumors, most commonly occurring in the head and neck, particularly the mandible and maxilla.
- They are frequently misdiagnosed as vocal polyps due to similar clinical presentations.
Observation:
- This case presents the first documented instance of a laryngeal myxoma in a female patient, located on the vocal cord.
- The patient, previously treated for a vocal cord polyp, underwent laryngomicrosurgery for bilateral edematous vocal cords, revealing a submucosal mass on the right vocal cord.
Findings:
- Pathologic diagnosis confirmed the vocal cord mass as a myxoma, a connective tissue tumor characterized by stellate cells in a mucopolysaccharide-rich stroma.
- Myxomas have a propensity for local recurrence due to their infiltrative nature.
Implications:
- Surgical excision of laryngeal myxoma must include surrounding normal tissue to minimize the risk of recurrence.
- Despite no detected recurrence in this case, the slow-growing nature of myxomas necessitates long-term patient follow-up.

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...

01:20Myasthenia Gravis: Overview and Treatment
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
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)...
01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
01:22Trachea
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...
