A 42-year-old man was diagnosed with cancer of the right lower lung lobe with a posteparterial type of tracheal bronchus, in which the posterior segmental bronchus of the right upper lobe arose from the distal bronchus intermedius. A mass involved the distal bronchus intermedius, requiring a right lower bilobectomy with an additional posterior segmental resection of the right upper lung lobe. T...

INTRODUCTION Tracheal bronchus is a right-sided anomalous bronchus arising from the trachea above the main carina and occurs in 0.1% to 2% of the general population. CASE PRESENTATION We present a case of left main bronchus obstruction during a left-sided double-lumen tube intubation in a patient with an unrecognized tracheal bronchus. After the intubation, to confirm the position of the tube...

A 75-year-old woman with no history of skin tumors came to our clinic complaining of hemoptysis lasting for three months. Chest computed tomography (Picture 1A) and an image of the left main bronchus on virtual endoscopy (Picture 1B) demonstrated endobronchial polyps in the left main bronchus and proximal portion of the lingular bronchus. Bronchoscopy revealed two polypoid tumors arising from t...

A bronchus arising directly from the trachea is an infrequent congenital anomaly which usually represents the displaced origin of a normal bronchus. Rarely, a true supernumerary tracheal bronchus occurs supplying an associated tracheal lobe. The case is described of a patient in whom a supernumerary tracheal bronchus and tracheal lobe was demonstrated by computed tomographic scanning and magnet...

This paper introduces basic Galois Theory, primarily over fields with characteristic 0, beginning with polynomials and fields and ultimately relating the two with the Fundamental Theorem of Galois Theory. This paper then applies Galois Theory to prove Galois’s Theorem, describing the relationship between the Galois groups of polynomials and their solvability by radicals.

Accessory bronchi arising from the trachea 'are rare in man (Boyden, 1955) but common in lower animals (McEwen, 1937). When present they commonly arise from the right side of the trachea, approximately 2 cm. above the origin of the right main bronchus (Brock, 1954). Accessory bronchi may be displaced normal branches or true supernumerary bronchi (FosterCarter, 1946). In the former the accessory...
