Abstract:
A 81-year-old man presented with massive hemoptysis and dyspnea. Results of chest radiography and computer tomography were highly suspicious for a large right-sided tumor of the bronchus with impression of the right main bronchus. Because of clinical worsening the patient was transferred to our department of pulmonology. The patient died of unappeasable hemoptysis the next day. At autopsy we found a 2-cm-diameter tumor of the proximal trachea as the source of massive bleeding and blood aspiration. Histological examination confirmed the tumor to be an epithelioid angiosarcoma of the trachea, which was a primary as no other tumor manifestation was detected. The entity of epithelioid angiosarcoma as a primary tumor of the trachea, to our knowledge, has not yet been reported.

Trachea
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...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
Anatomy of Respiratory System II: Lower Respiratory Tract
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
Esophageal Strictures-I: Introduction
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...
