Clinical Case Reports
|February 24, 2025
Summary
Respiratory epithelial adenomatoid hemartoma (REAH) is a non-neoplastic overgrowth of glandular tissue. This report details a rare case of REAH located on the nasal floor, a previously undescribed site.
Area of Science:
- Otorhinolaryngology
- Pathology
- Oncology
Background:
- Respiratory epithelial adenomatoid hemartoma (REAH) is a benign glandular lesion.
- REAH is uncommon in the upper airway, typically affecting the nasal septum.
- No prior cases of REAH attached to the nasal floor have been documented.
Purpose of the Study:
- To report a novel case of REAH occurring on the nasal floor.
- To highlight the diagnostic challenges and management of this rare condition.
Main Methods:
- A 56-year-old male presented with nasal obstruction.
- Diagnostic procedures included nasal endoscopy and CT scan.
- Surgical management involved endoscopic excision of the lesion.
Main Results:
- A large, lobulated lesion was identified on the nasal floor.
- Histopathological examination confirmed REAH.
- Complete endoscopic excision was successfully performed.
Conclusions:
- REAH can occur in rare locations, such as the nasal floor.
- Endoscopic excision is the definitive treatment.
- REAH may be underdiagnosed, emphasizing the importance of accurate diagnosis to avoid overtreatment.

01:16The Respiratory System
79.4K
The respiratory system is comprised of the organs that enable breathing. Air enters the nostrils and mouth, followed by the pharynx (throat) and larynx (voice box), which lead to the trachea (windpipe). In the thoracic cavity, the trachea splits into two bronchi that allow air to enter the lungs. The bronchi split into progressively smaller bronchioles and terminate in small groups of tiny sacs in the lungs called alveoli, where gas exchange occurs.

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
890
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.

01:05Breathing
58.2K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

01:21Barrett Esophagus-I: Introduction
55
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
