Abstract

Pulmonary hamartoma is an uncommon benign tumor consisting of a mixture of loose fibromyxoid tissue, cartilage, fat, and cleft-like spaces lined by cuboidal or ciliated epithelium. Cytologically, the presence of a mesenchymal component is essential for the diagnosis of pulmonary hamartoma. We report the fine needle aspiration cytologic findings of two cases of pulmonary hamartoma. Case 1 was a 71-year-old woman with a mass, measuring $1.8{\times}1.5cm$ in the upper lobe of the right lung. Case 2 was a 51-year-old woman with a mass, measuring $2.3{\times}2.0cm$ in the lower lobe of the right lung. Fine needle aspiration cytology of both pulmonary masses revealed several sheets of loose fibromyxoid tissue fragments with focal cartilaginous differentiation and a few clusters of bland cuboidal epithelial cells on the bloody background. The diagnosis was histologically confirmed by needle biopsy.
