Tracheal tumors are rare and difficult to diagnose. Moreover, delays in diagnosis are very common because the symptoms are nonspecific. As a result, tracheal tumors are commonly mistreated as chronic obstructive pulmonary disease or bronchial asthma. We report a case of a 49-year-old male who presented with a 3-month history of dyspnea and cough. Chest computed tomography scan showed a 1.5×1.3 cm homogenous tumor originating from the right lateral wall of the tracheobronchial angle into the tracheal lumen as well as a 0.5×0.4 cm round nodular lesion at the right upper lobe with multiple mediastinal lymph nodes enlargement. Bronchoscopic findings revealed a broad-based, polypoid lesion nearly obstructing the airway of the right main bronchus. The patient was diagnosed with pleomorphic adenoma which is the most common benign tumor of the salivary glands, but rarely appears in the trachea. Upon surgery, tracheal pleomorphic adenoma and co-existing active pulmonary tuberculoma that had been mistreated as bronchial asthma over 3 months was revealed. Following surgery, the patient underwent anti-tuberculosis treatment. No recurrence has been detected in the 3 years since treatment and the patient is now asymptomatic.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects the medium-sized muscular arteries, with occasional involvement of the small muscular arteries. As with other vasculitides, PAN can affect any organ system, including the cardiovascular, gastrointestinal and central nervous systems. The prognosis for patients with untreated PAN is relatively poor, with five-year survival rates of approximately 13 percent. The outcome has improved with proper therapy to approximately 80 percent survival at five years. We report here on a case of a 46 year old man with polyarteritis nodosa and who suffered from pulmonary tuberculosis.
