Reported is a hitherto unrecognized association of pulmonary hamartomas with salivary gland-type tumors showing myoepithelial differentiation, namely, a case of myoepithelioma arising in a otherwise classic hamartoma with cartilage predominance, and a case of malignant mixed tumor arising in a predominantly fibrous hamartoma resembling müllerian adenofibroma. The tumors occurred in middle-aged female patients of 35 and 44 years, respectively, and presented as 7 cm (treated with lobectomy) and 13 cm (treated with pneumonectomy) masses of the right upper lobe showing a short clinical history of cough, dyspnea, and wheezing. Both lesions did not present regional lymph node metastases after mediastinal lymphadenectomy. The myoepithelioma patient was well with no signs of recurrent disease at 6-month clinical control, but she was then lost to follow-up; the malignant mixed tumor patient is alive and well after 6 months since operation. Both tumors presented with morphologic and immunohistochemical features of myoepithelial cells, and we interpret them as being derived from a myoepithelial-like stromal cell population found within the hamartomatous areas, which is also consistently detected in classic pulmonary hamartoma. The lack of individual cell necrosis, mitotic activity, cell atypia, and pulmonary parenchyma infiltration supported a diagnosis of benign or unproven malignant potential tumor for the myoepithelioma, whereas the reverse held true for the other tumor in which the diagnosis of malignant mixed tumor of the lung was rendered. Their main importance of recognizing this association lies in separating these tumors histologically from other monophasic or biphasic tumors, either primary or secondary, such as pulmonary sarcomatoid carcinomas or true sarcomas, and metastatic salivary gland tumors, spindle cell carcinomas, melanomas, and soft tissue and visceral sarcomas.
