SARCOMATOID CARCINOMA OF THE LUNG

Sarcomatoid carcinomas of the lung are very uncommon tumors and their biological behavior remains controversial. Here we describe a case of a 62 year old male with an endobronchial mass and subjected thereafter to right upper and middle bilobectomy. A squamous carcinoma with a sa rcomatous component resembling a fibrosarcoma was found at microscopic examination. Although there is neither agreement on the denomination nor on the histogenesis of these tumours, it is recognized that they a re highly aggressive. Therefore, in order to provide the best possible treatment it appears recommendable to supply a detailed description o f the different components of the tumor at the time of the histopathol ogical diagnosis.
