Pulmonary hamartomas are uncommon benign tumors, usually discovered radiologically as a solitary coin lesion in asymptomatic individual. The approach to the patient with a peripheral lung nodule has changed with the increasing acceptance of fine needle aspiration cytology(FNAC) as a rapid, safe, inexpensive, and highly accurate diagnostic tool. However, a few reports describing the FNAC findings of pulmonary hamartoma have appeared in the cytologic literature and the experience of FNAC is limited. We reviewed all 9 cases of pulmonary hamartoma with histologic confirmation after FNAC seen at Asan Medical Center since 1995 to evaluate cytologic findings and to determine the value of FNAC in identifying that lesion. Originally, seven of nine patients were diagnosed as pulmonary hamartoma, while two patients were diagnosed as inflammatory lesion and adenocarcinoma of each. On review, eight of nine patients were considered as diagnostic of pulmonary hamartoma. The diagnostic findings in FNAC of pulmonary hamartoma were the presence of fibrillary myxoid tissue with spindle cells as well as hyaline cartilage.
