sulfur mustard (sm) gas was used in the iran-iraq war (1981 - 1989) as a vesicant chemical warfare against the iranian warriors. this alkylating agent with the potential of producing chemical injury in the skin, eyes, and lung, may damage both upper and lower respiratory tract, which in turn can cause different types of sequels such as asthma, bronchiectasis, chronic bronchitis and lung fibrosi...

Over the past four years (1360-1364) we have surgically treated seven infants for lobar emphysema. The pathologic lesion in all patients was in upper lobe of the left lung. Respiratory distress and pneumonia are the cardinal symptoms of patients with this abnormality. Diagnosis is confirmed by chest x-ray. The treatment of choice is lobectomy of affected lobe. 

Pulmonary nodular lymphoid hyperplasia (PNLH) is a reactive lymphoid proliferation manifesting as multiple solitary nodules or localized infiltrates in the lungs.
