[The diagnostic challenge of a rare pulmonary neoplasm].
Primary pulmonary sarcomas account for less than 0.5% of all thoracic neoplasms.  They're aggressive tumors arising in mesenchymal cells from the bronchial  walls, vessels or pulmonary interstitium. The authors present a patient in which  the diagnostic pathway ended with the diagnosis of a primary pulmonary leiomyosarcoma.  This case was a true challenge, illustrative of the difficulty associated with  this type of neoplasm, but also regarding its aggressiveness, considering its  rapid and fatal progression.
