For a long time the discovery of the solitary pulmonary nodule has remained a difficult problem to solve and has attracted a great deal of attension in recent years. Circumscribed coin lesion of the lung were generaly peripheral in location with respect to the pulmonary hilus. Because of this, important clinical problem in management and diagnosis arise. Such a lesion is discovered through roentgenologic examination. So the roentgenologist is the first be in a position to offer advise. This presentation is an attempt to correlate a useful diagnosis with roentgenologic finding of pulmonary coin lesion which enables us to get differential diagnosis of benign and malignant lesion. Histologically proven 120 cases of the pulmonary coin lesion during the period of 8 years were reviewed through plain film tomogram, bronchoscopy, variable laboratory findings, and clinical history. The result are as follows ; 1. Male to female sex ratio was 3 : 1 In age distribution, most of the malign nt pulmonary coin lesion appeared in 6th decade (39%) and 5th decade (27%). In benign lesion, the most cases were in 3rd decade. 2. Pathological cell type are as follows ; Primary bronchogenic cancer, 43.3%, tuberculoma 25.8%, inflammatory lesion 17.5%, benign tumor 10%, & bronchial adenoma, harmartoma, A.V. malformation, mesothelioma, are 1 case respectively. As a result benign and malignant lesion showed equal distribution (49.1% : 50.3%). 3. In symptom analysis ; cough is the most common (43.5%) symptom in malignant lesion, next follows hemoptysis (20.9%) and chest pain (14.5%). In benign lesion, most of the patient (32.77%) did not complain any symptom. 4. In malignant lesion, the most common nodular size was 4 cm (32.3%), and in benign lesion 2 cm sized coin was most common (39.3%). 5. In general, margin of nodule was very sharp and well demarcated in benign lesion (83.3%), and in malignant lesion that was less demarcated and poorly defined. 6. Most case of calcification (82.7%) was seen in benign lesion, and the most common type is central nidus. 7. Cavitary lesion (12.5%) of thick walled irregular margin with eccentric location in the coin lesion is indicative of malignant coin lesion. 8. Stellate lesion was 7 cases and all of them were seen in tuberculomas.
