Abstract
Tracheal bronchus is a rare, congenital abnormality of the tracheobronchial tree. Majority of patients with tracheal
bronchus are asymptomatic. Lung malignancy associated with tracheal bronchus is rare. An asymptomatic
40-year-old female was diagnosed with right upper lobe lung carcinoma. CT thorax revealed a right upper lobe
tracheal bronchus. The patient underwent right uniportal video-assisted thoracoscopic (VATS) lobectomy and
recovered well. To our knowledge, this is the first reported case of primary lung carcinoma with tracheal bronchus
treated with right uniportal VATS upper lobectomy in Malaysia, and the second reported case internationally.

Keywords: Case report, tracheal bronchus, primary lung carcinoma, uniportal video-assisted thoracoscopic,

INTRODUCTION
Bronchovascular variations exists in the general population but are often only diagnosed pre- or intra-
operatively. Tracheal bronchus is a rare congenital variation of the bronchial tree structure and can be seen
[1-5]
in 0.1%-3% of population . Primary lung cancer in association with tracheal bronchus is an even rarer
entity [1,6,7] . We present a case of a middle-aged female with right upper lobe carcinoma, tracheal bronchus
and other bronchovascular variations, who underwent uniportal video-assisted thoracoscopic (VATS) right
upper lobectomy and lymphadenectomy.
