Pulmonary hamartoma is the most common benign tumor of the lung but rarely encountered in routine cytologic work-up. We recentely experienced a case of fine needle aspiration cytology of pulmonary hamartoma in a 65-year old male patient. The characteristic cytopathologic features were 1) The mesenchymal components with cuboidal epithelial cells in a clean background, 2) The presence of fibromyxoid mesenchymal component composed of fibroblasts in a loose fibrillary stroma, and 3) Antler-liker fibromyxoid cluster having the rimming of epithelial cells which correspond to the epithelial glowing in cleft-like fashion in pulmonary hamartoma.
