INTRODUCTION: Primary lung tumors showing features of salivary gland-type neoplasms are extremely rare. We report a case of bronchial pleomorphic and mucous gland adenomas and study the expression of markers such as TTF-1 and high molecular weight keratins in the tumor. The pleomorphic adenoma also had a well-circumscribed parenchymal component, with a biphasic morphology composed of epithelial and myoepithelial cells in a background of myxoid and hyaline stroma. Epithelial cells showed strong and diffuse cytoplasmic staining with high molecular weight cytokeratins and lacked TTF-1 expression.
