International audience; Introduction: Sclerosing pneumocytoma is a benign and rare lung tumor affecting epithelial cells. In most cases, patients are asymptomatic and the diagnosis is made on an X ray or a CT scan performed for other enquiry. Sex ratio favors women. Epidemiological studies report that middle-aged Asian women are more frequently affected. Radiological investigations find a solitary nodule or a mass with peripheric localization. When performed, histological analysis shows a tumor composed of at least two of the four following architectures: papillary, sclerosing, hemangiomatous and solid, with two types of cells that can be round or cubic cells.Cases report: We report two cases of multiple sclerosing pneumocytoma in two caucasien men. The first patient was asymptomatic, the second complain from moderate dyspnea. A wedge resection was performed in both, allowing diagnosis. Anatomopathology revealed respectively a predominant sclerosing and solid architecture and a sclerosing and papillary architecture. There was no progression of the other concomitant nodules after three years follow-up.Conclusion: Pneumocytoma is a benign, slow-growing tumor with good prognosis.
