[Angioleiomyosarcoma of the lung--primary tumor or metastasis?].

Pulmonary angioleiomyosarcoma was diagnosed in a 69-year-old women by evaluation of lung tissue obtained during thoracotomy. The primary angioleiomyosarcoma of lung is a very rare leiomyomatous neoplasm of the smaller pulmonary vessels with about 100 cases described so far. Sometimes it is difficult to distinguish tumorous processes with mainly fibroblastic components and to determine the dignity in particular cases. The reliable decision only succides in surgical obtained tissue. The clinical course of disease is--like in the presented case--determined by recurrence of tumor and metastasis into other regions.
