Abstract:

Alveolar adenoma is a rare and a benign tumor of the lung. There is few case of alveolar adenoma in the literature. This paper presents a case with this rare tumor. A 52 years old female patient was admitted with complaints of cough and dispnea for five months. Chest radiograph showed a solitary pulmonary nodule between third and fourth anterior costa with 3 cm diameter and well defined borders. Computed tomography of the thorax demonstrated a well circumscribed, cystic nodulan lesion without calcification on right middle lobe. Fiberoptic bronchoscopy revealed normal endobronchial system. Cytology was not diagnostic of any disease. MR angiography of the thorax showed a solitary pulmonary nodule on right middle lobe. No relation with vascular structures were detected. Solitary pulmonary nodule was palpated during thoracotomy. Frozen cytology of the nodule was reported as benign and wedge resection was performed for excision. Pathological diagnosis of surgical specimen was alveolar adenoma.
