Squamous cell carcinoma with sarcoma‐like stroma of the nose and paranasal sinuses: report of two cases

Abstract
Two cases of squamous cell carcinoma with sarcoma‐like stroma of the nose and paranasal sinuses are described. To the best of our knowledge, this is the first report of such a localization for this tumour type. Keratin was localized by immunocytochemistry in the epithelial cells, as well as in occasional stromal‐like elements. The importance of distinguishing these tumours from morphologically similar neoplasms is emphasized in view of their different therapeutic approach.
