Endobronchial myxoma - Case report [Mixoma endobrônquico - Caso clínico]

Introduction: pulmonary myxoma is an extremely rare benign neoplasm. it is mostly parenchymal but may occasionally occur within the tracheobronchial tree. there are very few reports of endobronchial myxoma. case report: we describe a case of endobronchial myxoma in a 40-year-old female patient with a history of asthma and repeated right-sided pneumonia. thoracic computed tomography (ct) showed medium lobe atelectasis. fiber optic bronchoscopy revealed a polypoid,well-circumscribed tumor,causing total obstruction of the medium lobe bronchus. biopsy of the mass was non-diagnostic. further study included a positron emission tomography (pet) which demonstrated low metabolic activity of the tumor and no evidence of neoplasia in other location. the patient was submitted to a medium lobectomy and microscopic examination of the tumor revealed myxoid stroma with lobulated pattern,elongated and stellate cells,compatible with myxoma. conclusion pulmonary myxoma is extraordinary rare and endobronchial location is very few reported in medical literature. © 2011 sociedade portuguesa de pneumologia. published by elsevier españa,s.l. all rights reserved.
