Summary
A rare dermoid cyst in a cat
Area of Science:
- Veterinary Medicine
- Surgical Pathology
Background:
- Nasopharyngeal masses in felines can present with respiratory distress.
- Differential diagnoses for nasopharyngeal lesions include polyps, tumors, and cysts.
Observation:
- A 2-year-old cat exhibited nasopharyngeal stridor and stertor.
- Initial endoscopic attempts to remove a nasopharyngeal mass failed due to fragmentation and hemorrhage.
- Histopathology and CT imaging confirmed a dermoid cyst.
Findings:
- Dermoid cysts are typically congenital and contain skin and hair elements.
- This case represents a previously unreported nasopharyngeal location for a feline dermoid cyst.
Implications:
- Recognition of dermoid cysts as a differential diagnosis for feline nasopharyngeal masses is crucial.
- Advanced imaging like CT is vital for accurate pre-interventional diagnosis.
- Complete surgical excision leads to favorable outcomes.

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
2.3K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

01:20Pharynx
2.4K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

01:23Chronic Pharyngitis
4.2K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:29Suctioning the Nasopharyngeal Airway
765
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

2.5K
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...

01:27Cranial Bones: Lateral View
2.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
