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 sarcomatous 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 are highly aggressive. Therefore, in order to provide the best possible treatment it appears recommendable to supply a detailed description of the different components of the tumor at the time of the histopathological diagnosis.
