Multiple pulmonary myofibromas mimicking metastatic disease in an adult patient

Abstract

We report a case of multiple bilateral pulmonary myofibromas in an asymptomatic 76-year-old man, who was referred to our institution for investiagtion of incidentally discovered pulmonary nodules, orginially suspected to represent pulmonary metastases. Myofibromas are unusual benign neoplasms, infrequent in adults, and rarely affecting the lungs. Pulmonary neurofibromas can mimic lung metastases and their diagnosis requires histopathological assessment.
