We report a case of a primary lung tumor characterized by complex gland-like spaces lined by simple cuboidal to columnar epithelium surrounded by a hyalinized spindle-cell fibroblastic proliferation reminiscent of adenofibroma of the female genital tract. The lesion occurred in a 56 year-old male with a history of left thoracic pain and hemoptysis. The tumor presented clinically as 1.5 cm solitary lesion and was discovered on chest X-rays. The lesion was treated by lobectomy. The main importance lies in distinguishing this lesion histologically from other types of pulmonary hamartoma, pulmonary blastoma, intrapulmonary solitary fibrous tumor and metastases from soft tissues and visceral sarcomas.
