Abstract
Myoepithelial neoplasm mainly occurs in the salivary glands and breasts and is extremely rare in the lung. To our knowledge, this report describes the first documented case of a myoepithelial carcinoma present in the lung. The tumor derived from the right main bronchial submucosa and exhibited a dual epithelial and smooth muscular phenotype by immunohistochemical and ultrastructural studies. It invaded the neighboring pulmonary tissue and the hilar lymph nodes. Despite a right pneumonectomy and chemotherapy, metastasis was found in the left lung 7 months later.
